Go Notes

September 25, 2020

5 games, 4.5 reverse komi. I won 4

game 1

I successfullly invaded Rik’s big shimari on the top right and took good territory on the bottom and up into the middle. I won by 16.5.

game 2

In the second game I gave up the entire top side. However, I had 2 good corners and a pretty big territory on the left. I won by 4.5.

game 3

Rik had a strong opening in the third game and got off to a good lead. I tried to wreck his middle and found my group in deep trouble. I escaped and made it close but Rik won by 3.5.

game 4

In game 4, I did pretty well negating Rik’s top side strength early on. Rik made an error on the bottom and I killed 2 stones. Later I killed 2 in the top right. I won by 10.5

game 5

My perspective on this game was that I invaded Rik’s strength and reduced his potential in the top left, and also killed 2 stones near the top. Harvey reviewed this one and suggested (among other things) that I never should have made the top left invasion that early, especially when there was a single stone on the right to attack. He also pointed out that I missed a lot of the endgame sente, costing me quite a few points. Still, I won by 7.5.

September 21, 2020

I again won 3 of 5 online games this session. We continued to play with a 4.5 point reverse komi for Rik.

game 1

Rik dominated the first game, winning by 16.5

game 2

The second game featured even development. Rik took 3 or the corners, but my 1 corner was pretty good. I got ahead in the middle game and hung on, winning by 2.5.

game 3

Rik got off to a good start in the 3rd game but in the middle game I broke through Rik’s defenses on the bottom and killed 2 stones, putting me ahead. I won by 4.5 points.

game 4

Game 4 was all about a big fight. Rik ran a group down from the top with me destroying his eye potential along the way. He found a way to connect up his stones. In review we saw 2 different ways I could have assured a kill. I wish I had seen them in the actual game. Rik won by 17.5

game 5

In the 5th game, I killed 2 stones on the left size, connecting my side to my bottom left corner and putting me in the lead. I won by 13.5.

September 17, 2020

We played 5 games online. I won 3.

game 1

Rik started on the 4-4, not unusual in Go but unusual for Rik. He staked a lot on a big framework on the top which ended up about 40 points. I took the corners with pretty good territory on the bottom right. I made a light reducing move against his big group, which was enough. I won by 13.5

game 2

Early in the second game we engaged in infighting on the top of the board. I had a weakness I was late to settle and Rik exploited my weakness by making territory along the sides for a big lead.

game 3

The third game was characterized by my killing his group on the top and then also his stones in the bottom left corner. A 19.5 point win for me.

game 4

In game 4, Rik had an early lead but I had a good wall in the top right. Unfortunately I failed to make the extension I needed to convert it when I had the opportunity. Rik jumped in and reduced my potential, winning by 13.5 points.

game 5

In our final game of the evening, Rik took 3 corners to my 1 larger corner. I was able to run stones through the middle and take some side territory for a 10.5 point win.

September 14, 2020

This session we played 5 and I won 4.

game 1

I started a joseki in the top right but instead of following it through, I shifted to a probe in the top left. I made a series of force moves including a ko (there are no ko threats at the beginning of the game). This opening propelled me into a lead and eventually I won by 16.5

game 2

In the second game I started with the sanren-sei, occupying the 3 star points on the bottom. Rik played a shimari in top left and again I tried a probe to bet a position and split the side. I won by 10.5

game 3

Rik was ahead through most of this game but I attacked his centre group, and he was unable to find the way to save the group. As usual it was clearer on review.

game 4

I neglected to protect a group of 4 stones inexplicably in game 4. It cost me the game. Rik won by 9.5

game 5

In the final game, I pressed Rik along the right side to the smallest size and made a strong wall. Rik tried to run a group out to break my potential. I attacked for profit. The win for me was just 4.5 points but there was no room for Rik to catch up and win.

September 11, 2020

We played 5 games online, continuing to play at even stones with Rik taking 4.5 points komi. While Rik has won other evenings in which he has needed the komi, this session he won 4/5 and didn’t need komi for any of his wins. On the whole he outplayed me until the last game. In most of the games, we identified on review a bad move I made which he exploited to gain a lead.

game 1

After a strong opening, Rik took 3/4 corners and shared the 4th. He was able to turn a couple stones floating in the centre to close to 15 points of territory. I had too many weaknesses to be able to attack them effictively.

game 2

A weak early move on the left side cost me dearly in the second game. Rik got a good top left corner and he strength there helped him reduce my side territory on the top. I did well on the bottom but it wasn’t enough.

game 3

In the 3rd game I saw an opportunity to break through Rik’s defenses on the top but I left behind a weakness and the result was that he greatly reduced my top left and managed to grab 25 points in the centre. I would have been better to let him take 3rd line territory on the top and expand my territory into the centre, grabbing that space for myself.

game 4

After Rik played a stone on the bottom in the second game I pushed up with my corner group. Instead, I should have forced Rik to take a base by extending from the left, then advance my stones on the right up to keep pressure on his stones and preserve more territory on the left for myself. I made it too comfortable for him to settle.

game 5

I got off to a strong start in the last game. I went right after his big shimari in the top left. The result was that the top was mostly a saw-off. I was able to get great territory in the bottom left. After my opening, it was an easy game for me.

September 7

We played 5 games online. Even game with a 4.5 point reverse komi to Rik. In the first couple games, that reverse. komi was difficult for me to overcome.

game 2

The first game was very even. On review we found one move I made which was actually unnecessary, giving up sente. Was that the difference? Rik won by .5 points

game 2

In game 2, in the early middle game, Rik overlooked an opportunity to kill my corner on the bottom right. He was a bit ahead when he missed an upcoming double atari. I killed 4 stones. Almost enough to steal a .5 point game.

game 3

The third game was a disaster for me. He had a weak group on the left and I started an attack. I wasn’t able to either kill or make gains elsewhere as a result. Rik won by 32.5

game 4

At move 14 in game 4 I played tengen. I made a mistake in direction that allowed Rik to break into my potential and threaten my stones in the centre – but I was able to recover ok. Rik had only cash and little more potential. I made an endgame kill of a few stones but was already ahead enough to win. I finally won by 35.

For some reason I don’t understand I can’t upload a screen shot from the fifth game, which I won by 22.5 points. Rik had 3 corners but I kept them small. He had 6 groups in this game and couldn’t get much territory with them. I didn’t have huge territories but easily more than him.

September 4

We played 5 games online last evening. Rik played black and took 4.5 reverse komi.

game 1

In the first game, Rik took 4 corners and aggressively tried to stop me from making any territory. This strategy left him thin. I started a splitting attack. He emphasized the upper group and I captured the side group for a 19.5 point win. I was worried about having to kill a group to win, as I’ve been playing somewhat sloppily lately, but I was able to secure the group calmly. I think Rik would have been better to give me some territory and keep his own groups stronger. It is true that had he survived everything he would have won but I think his strategy was unreasonable.

game 2

We started the second game with 3-4s all around. Rik took 2 shimaris and I blocked the big extensions by playing around the star points. He was ahead going into the endgame, but made a mistake allowing me to kill off 6 stones for a 3.5 point victory.

game 3

The key move in this game was a beautiful tesuji on Rik’s part, attacking my right side invasion group. I saved the main group but he took 4 stones in a flower shape. He went after 2 more, but that was a mistake, as it allowed me to break through to the right side, separating his corner stones. he was able to save the corner for a 3.5 point win.

game 4

I made a mistake in the middle game in the 4th game, choosing to atari an invasion stone in the wrong direction. The result was Rik was able to run the stone and my potential was erased. This left him quite a bit ahead. I could not catch up and resigned.

game 5

Our last game of the evening was a scrappy and messy one without a lot of territory on the board. Rik won by 7.5.

August 28

Last session we played 5 games and Rik won 3.

game 1

The evening started with a 26.5 point win for me. I stole Rik’s top right corner. This led to a splitting attack against 2 groups plus I was able to steal the bottom right corner. Rik was left with one big territory at the bottom left, but not nearly enough.

game 2

One of the themes to this evening’s session has to be woulda/shoulda. In this game, Rik set up a big centre moyo. It was ominous but I broke through and won a close 5.5 point game. On review, Rik identified what he ought to have done to defend against my breakthrough invasion. It would have been game-winning.

game 3

In this game I played poorly against the top right corner by playing a knight’s move toward the corner instead of simply making a base. I found myself behind and while I did everything I could think of to catch up I still lost by 5.5

game 4

Rik had a good start to game 4. I was behind but I still thought I had a chance…until he found a tesuji that tore apart my position in the top right sector of the board. It was a beautiful attack and I was forced to resign.

game 5

More woulda/shoulda. I got off to a great start in game 5. Rik made a decision to run out a weak group. If I killed it, it was game over. In the game, he escaped, connecting up to the bottom. I took points above that group but still he won by 5.5. On review, it was obvious there were 3 places during the battle in which I could have sealed the deal and killed his group, yet during the actual game, I couldn’t see them. Very discouraging.

August 24

Last night we played 5 games online with the usual handicap. The results were 3-2 for Rik. Three of the games were decided by a hair.

game 1

Rik won the first game by 1.5 points. It was an excellent, well-fought game all around.

game 2

I gave up all the corners in the 2nd game and early on that strategy looked poor. Rik played to stop me from getting territory at every turn, and I erased his territory as well. By about 3/4 through the game I felt I had pretty much caught up and had a shot at the game but Rik took it by a half point.

game 3

In the third game I went after cash early and Rik pressed me down so my cash didn’t look promising. He had a big ugly outside wall on the right side that really worried me. However, I was able to create a situation where cutting off the bottom chunk of that wall and chase it for profit. I did really well out of this. Once he found a way to survive his group, I allowed the connection, but at that point I had done a lot of damage, taking the bite out of his wall and building up good centre territory myself. I won by 20.5

game 4

Game 4 was another tough close match, this one littered with kos. I had a bit of an edge and hung on to win by 2.5.

game 5

Our final game of the evening was one featuring large territories. Rik won by 8.5 but the score is deceptive. He developed a strong lead then played a conservative game. I caught up some but it seemed impossible for me to win.

August 21

Last night we got a late start and only played 4 games. That must be the fewest games we’ve played in a session in a very long time. I won 3 and Rik won 1.

Rik started the evening with a strong game (sorry no screen shot). I played an invasion on the left side. I should have jumped out to the centre but didn’t and he attacked my group effectively. I should have let the stones go and played on the outside but instead I tried to survive them. I did so but the cost was really high and I was well behind, finally resigning the game.

game 2

In the second game, I took 3 corners. Rik played too slow defending 3rd line territory on the left. Instead I think he should have jumped to the centre, creating an ambitious moyo. As well this game I had more than my share of sente. Rik finally resigned.

game 3

The 3rd game was decided by just half a point in my favour. Rik was sure he had won this game and the server had miscounted, but finally determined he neglected to count F6-7 for white. Rik’s strategy for grabbing 3 corners and some middle was strong, but he did make some mistakes which allowed for some profit on my part. I felt fortunate to win this one.

game 4

Rik misplayed the top left corner and I killed it, putting him behind early. It seemed to me that he didn’t want me to have anything this game, not the top left corner, not the left side and not the outside. It was unreasonable for him to expect to take everything. It is after all a game of give and take. I won this one by 37.5. I think he would have been better to emphasize fewer areas but be more ambitious in those areas.

August 17

game 1

Last night we played 5 games online, continuing with my giving Rik 2 stones and receiving 6.5 points komi. Rik has continued to play well, and again won 3/5. We started with a good close game. On review it was clear I should have capped to kill the weak group he ran out from the right side. He won by 3.5

game 2

In the second game it looked like I was going to win by just a few points, but I invaded his corner and survived for a 20.5 point win.

game 3

Rik tried to establish a big moyo outside the bottom left corner. I invaded on the sector line and created a strong group for a 4.5 point win.

game 4

In the 4th game, Rik threatened to take a lot of territory on the right side. He ran out a weak group from the top left and I chased it down the board but his position gained more strength we descended. He won by 4.5

game 5

The 5th game was Rik’s best game of the night. I made a couple poor directional choices and he took full advantage.

August 16

We played 5 games on the 13th. I’ve been busy with a lot of other things and haven’t got around to putting together any comments about the games, beyond that Rik had a winning evening and generally outplayed me. He won the 1st by 6.5, the 3rd by 12.5 and the 5th by 3.5. I won the 2nd by 19.5 and the 4th by 1.5. Here are the game records.

game 1

game 5

August 11

We played 5 last night at the usual handicap. I won 3/5. It may be noteworthy that Rik’s wins were squeakers compared to my wins – 13.5, a resignation, and 55.5

The first one was tight. I missed a chance at killing a centre group and Rik won by 2.5.

game 1

game 2 (white wins by 13.5)

In the 3rd game, I went for a big centre territory but Rik broke through and won by half a point.

game 3

game 4

I took 3 corners including a big top left which grew into good centre. Rik finally resigned.

game 5

Rik got off to a bad start, misplaying a joseki and losing his stones in the top right. Easy game for white – 55.5 points.

August 8, 2020

The night before last, we played 5 games online, a 3-2 result in my favour. It started badly for me. Rik approached my top right corner and I should have simply blocked without giving it a second thought. Unfortunately my little brain was focused on action in the middle of the board, trying to figure out if there was some kind of forced attack I could make. I failed to block and he killed my corner and just like that the game was over.

game 2

game 2

In the second game, I thought Rik got ahead early, but I chipped away at it and came close to stealing the game, losing by just 2.5 points.

game 3.jpg

game 3

In the 3rd game, Rik decided to run a weak group from the right side of the board. This was a high-risk idea because it meant the whole game rested on the survival of that group. I ended up killing 29 stones for a 40.5 point win. On review, we found a successful counter-attack for Rik, but he was unable to find it in the heat of battle.

game 4.jpg

game 4

In game 4 I got a nice wall against Rik’s bottom left corner and turned it into the best territory on the board. in the top right I got the corner but also got modest territory outside of Rik’s covering stones. I won by 17.5,

game 5.jpg

game 5

The last game was interesting in that Rik invested in getting a very large territory on the right side. I mitigated it a little by taking the top right corner. As formidable as his side was, I had a really good top left that spilled out into the middle, and also a good bottom. I won by 9.5  August 4, 2020

The other night we played 5 games online – I again won 4.

game 1

Game 1 was a close match throughout. The tide turned around move 85. Rik had a weak group and to survive it he ran toward his moyo. I followed, keeping the pressure on, destroying potential along the way. Rik missed an opportunity to create a ko later, which may have enabled him to catch up. I won by 5.5.

game 2

Another close one. I won by just 2.5

game 3

In the 3rd game, Rik tried to make territory outside my top right corner, but I was able to reduce it quite a bit. I pulled ahead in the middle game and held my lead for a 12.5 point win.

 

game 4

Game 4: yet another close one.

game 5

Game 5 was Rik’s best game of the night. He kept a lead through much of the game. I found it difficult to destabilize his positions this game.

July 31, 2020

I won 4/5 games last night.

Overall, I’ve had a great July. Rik started the month off by winning 4/6 and then 3/5, but then I won 4/6, 3/5, 4/5, 3/5, 4/5 and 4/5. I won a total of 26 games to Rik’s 16. So at this handicap, I’ve got a 62% win rate for July.

game 1

Just over 20 moves into the first game, Rik made what I think is a glaring error. He played R11, which extended his top right corner territory a modest amount in gote. In doing this he allowed me access to R5. In this corner situation, the very best he can hope for is to survive and give up huge outside strength. I killed the corner easily, giving me a big early lead. After this I played a conservative game, taking decent, safe positions and won by 15.5. In my opinion, if Rik kicks against a kakari against a 3-4 stone, he should follow it up with a 1 space or possibly a 2 space jump along the side from that corner. I have to then extend from my pillar. If you kick you need to finish the corner. Alternatively, Rik could respond to the kakari by making a pincer, putting pressure on the kakari stone. I can respond to that by pressing and the result can be joseki.

game 2

The second game was quite even. When I counted in the middle game, I thought he was a little ahead, but gradually I caught up and won by 4.5 points.

game 3

Rik got off to a strong start in the 3rd game. I tried unsuccessfully to invade the bottom left corner. I found myself with little potential for decent territory. I needed a kill to win but his groups were stong and I couldn’t find a target.

game 4

In the 4th game, I connected up my bottom territory to my side territory. Rik had 3 corners but I contained those and did not allow much outside my 1 corner.

game 5

Again Rik claimed 3 corners and they were pretty good, but I was able to come out toward the centre with my1 corner and make my territory 3 dimensional, getting almost 50 points. I won by 10.5.

July 28, 2020

We played 5 games online the other night, and again I had an edge, winning 4 of them.

game 1

Rik started the evening off with a strong game. On review, we discussed an opportunity I missed to invade his right side, a move which would have made the game close. He won by 11.5

 

game 2

In the second game, I got off to a strong start. Rik came close to catching up….but not quite. I won by 4.5.

game 3

In the 3rd game, I caught 7 stones in the bottom left about 90 moves in. In exchange, Rik weakened my 3 outside stones. I took a move to strengthen them, though and made some centre territory. At about move 185 I threatened to push into Rik’s top area. He responded by attacking a single stone in the centre, but even if he captured that stone, I could contain him. I ignored his move and advanced, erasing lots of his potential territory in the top right. I won by 27.5

 

game 4

Rik was doing ok in game 4 until I caught 4 stones and stole the top right corner. This was devastating to his chances and I won by 25,5.

game 5

I took the bottom corners, but Rik made a great big moyo between them. This promised to be difficult to overcome but I was able to steal the top right corner for a 6.5 point win.

July 23, 2020

Game 1

I won 3/5 online last night, but I needed a blunder on Rik’s part to accomplish it.

In the first game, Rik got off to a strong start and maintained a lead throughout for an 8.5 point win.

Game 2

He would have won the second game too but blundered away 10 points and lost by 8.5.

Game 3

In the 3rd game there was a window of opportunity for me to split Rik’s big group on the left but instead I came out on top into the centre. It turned into an easy win for him – 14.5 points.

Game 4

In game 4 I was able to cut off 6 of Rik’s stones on the right side. Once they were dead, I had an easy time winning by 20.5. On review we could see there was a narrow opportunity for Rik to try to run them out. I don’t know if he could do it successfully or not but on review it looked as if it was his only chance to win.

Game 5

In the last game, Rik had good potential on the bottom, but I was able to establish a position and also run some stones out to the centre, getting underneath a group of stones and surrounding but not killing them. This turned out to be quite powerful, giving me centre influence and reducing his right side potential. I won this one by 13.5.

July 20, 2020

I took 4/5 online games last night, but I needed the 6.5 point komi to win 2 of them. I’m still giving Rik 2 stones.

game 1

We started with a good scrappy game marred by a blunder on Rik’s part, which cost him 10 points. I won by 14.5

 

game 2

I misplayed the bottom right in the opening, choosing to play on top of the corner when I should have blocked on the left side. Rik won by 14.5

game 3

In the third game, Rik misplayed the bottom right corner and I killed his stones. Much later, he disconnected 5 of my stones from my base in the top left and killed them but it wasn’t enough to catch up. I won by 9.5

 

game 4

Game 4 featured a good equitable opening. I dove into his moyo in the bottom left sector but Rik proved to me it was a little deep. I salvaged the situation to some extent but had to give up a stone. In the top right, I successfully invaded his corner. I won by 3.5

 

game 5
game 5

In the 5th game, I successfully invaded the top right corner and to make matters worse, I pushed further down, winning this one by 3.5.

July 15, 2020

We had an exciting set of 5 games this time out.

Game 1

In the first game I found myself behind in the middle game. I looked for something I could kill to catch up and take the lead. Rik had a centre group which didn’t have life shape but he did have many liberties and there was a lot of open area above and the possibility of connecting up as well. I didn’t think I could win unless I killed the group so I launched an all-out attack. Needing to kill a group to win is not a position I want to be in, but I felt I had no choice. It was a very complicated battle and even after review I’m not sure if there were better lines of play for me or not. I was not able to kill the group and lost by 11.5. Very exciting game.

game 2

In the second game, Rik invaded deep into my right side framework. As it turned out it was too deep and I killed off 10 stones. Later in the game, Rik left a big weakness in his bottom left corner group. I found the invasion that destroyed his shape and he was left with nothing more to do than click resign.

Game 3

In the third game, I got off to a great start, and was able to maintain a good lead throughout the game until Rik finally resigned, unable to find any way to catch up.

Game 4

In game 4, we each claimed good chunks of real estate, but Rik had more and there wasn’t much aji for me to exploit. Late on, Rik attacked my top right/side group. I misplayed it and lost part of the group and resigned. On review it was obvious to me what I ought to have done.

Game 5

I think when I stole the top right corner in Game 5, it gave me a decent lead. I held onto it and won by 11.5.

July 12, 2020

Adjusted handicap: 2 stones, 6.5 komi.

I won 4/6 and needed komi to win one of them.

Game 1

I had a good, fast opening to start the evening, then got more of the big endgame points than Rik, for an 8.5 point win.

Game 2

Rik came right back in the second game, holding a lead throughout.

Game 3

In the 3rd game, I caught 4 stones at the top just 30 moves in and pressured another group. As well, I had strong invasion on the right side. I won by 9.5.

 

Game 4

The result of this game had much to do with my successful invasion into Rik’s corner enclosure in the bottom left. I won by 23.5.

Game 5

Game 5 was a close one. I needed the komi to win by 1.5.

Game 6 before the endgame kill

In game 6 I thought the game was over and took the screenshot but Rik showed me my centre group was not so safe after all. It was a close game until he killed some centre stones for a 20.5 point win.

July 7, 2020

Rik had another winning evening, taking 4/6 games. Next session we’re going to adjust the handicap back so that I continue to give 2 stones but I once again receive 6.5 points komi.

Game 1

In the first game, Rik got off to a strong start and held the lead throughout. I couldn’t find a way to catch up and finally resigned.

I didn’t take a screen shot of the second game. I had thought I had misplayed the early middle game but it turned out my position was better than I imagined. I was able to get out to the centre from my upper left position, allowing me to pressure some stones in the middle of the board, which I killed off for a 32.5 point win. One note on this game. Rik played for a ko in the bottom right which was going to be hard for him to win. He should have simply settled the area.

Game 3

In the 3rd game, Rik made a close invasion against my wall – hard to kill. I moved away from the key battle too early. Rik won by 16.5

Game 4

Game 4 was quite scrappy. I got 3 corners and killed 3 stones on the bottom. I won this game by 26.5 points.

Game 5

In the 5th game, Rik took a really big territory on the top and held his own elsewhere. I couldn’t find enough potential anywhere. Rik won by 18.5.

Game 6

In game 6, Rik had a lead, but I successfully invaded his bottom left corner and just about stole the game. He won by 1.5 points.

July 3, 2020

Rik won 3/5 games last night. The first game was the most interesting because it was a comeback game. Rik did really well through the first half and I found myself well behind. However, he had some bad aji which I was able to exploit. Here is the final game, which I won by 25.5 points

game 1

Here is one of the attacks.

white attacks

In the second game, Rik limited my top nicely then started forming centre territory. He was well ahead with centre + 3 corners when I resigned.

Game 2

Game 3 was a close one. Rik made a right-side moyo. I invaded then established a good position. Rik won this one by 4.5 points.

game 3

Early on in game 4, Rik trapped 6 stones, creating good corner and side territory. I fought back and evened things up. In endgame, I brought 2 stones back to life which gave me my 5.5 point margin of victory.

game 4
game 5

Game 5 was an easy 23.5 point win for Rik.

 

June 28, 2020

Game 1

Rik had a great evening, defeating me 5 games in a row. In the first game, I pushed up against Rik’s bottom right corner. On review it seemed obvious I should have extended out instead. This gave Rik a lead, which he was able to maintain through the game.

Game 2

Game 2 was the closest game of the evening. Rik won by 5.5 points. I killed 6 stones early in the bottom left by splitting Rik’s forces. It turned out to not be quite enough to win.

game 3

Game 3 was painful for me. I had quite I thought was a strong moyo in the top left. Rik split my stones, destroyed my moyo and stole the corner, for an easy 17.5 point win.

game 4

In game 4, Rik took a little more than me everywhere and it added up to a 15.5 point win.

He continued to dominate through the last game where I finally resigned, hopelessly behind again. This was Rik’s best night since January. Has he figured out how to use his handicap successfully to win consistently? For sure his play was very strong. I found his shapes hard to attack and I was under pressure in most of the games. The first two games were in reach for me, but the others were fairly easy wins for Rik.

June 25, 2020

Rik had his most successful night of play last night, since around the time I returned from Vietnam back in February. We continued at 2 stones with .5 komi and he won 3 of the 5 games we played. The first game was a half point game. All the others were decisive one way or the other.

game 1

Early on in the first game, Rik played a probe in the top left. He forced me to kill his invaders in exchange for a position on the outside. I failed to recognize I could have severely attacked his outside stones but for unexplained reasons I could not see it until Rik defended the area. It turned into a very tight game, and Rik won by a half.

Game 2

In the second game, Rik made a mistake in the bottom right and I caught 5 stoned and gained a great position and leading to a fairly easy game for me. Late in the middle game, Rik separated my stones in the bottom left from my force. I was ahead enough to win even giving them up, but I found a way to connect them up with a ko. There was a second two-step ko available to Rik on that group which he didn’t recognize.

Game 3

Rik established an early lead in gae 3 and held on to it. I got myself in trouble early, making an ill-considered invasion at move 14 – too deep and too weak.

Game 4

I stole two corners off the top in game 4, then played tengen on move 19 as a big ladder block on opposite corner areas. The main theme in this game was my attack on his group on the left side above centre. I destroyed his eyes and blocked his exit, killing 16 stones, winning the game by 23.5.

Game 5

Although I took 3 corners, they were small. Rik jumped out to a lead and maintained it through the game, winning by 20.5.

June 21, 2020

Last night we adjusted the handicap so it is now 2 stones and I get just .5 komi instead of 6.5. We played 5. Each of us won 2 by decisive margins and I won the last by 5.5 points.

game 1

In this game I was able to significantly reduce Rik’s moyo on the left side to a handful of points. I was also able to bring 3 stones back to life in doing so. I won by 10.5

In the second game, I was able to kill 12 floating stones + stole the top right corner for a 45.5 point win.

game 3

Rik won the third game by 17.5 points. Rik played a good reduction stone agains my group on the left. On review, it was obvious I should have attacked that stone right away. I didn’t and it easily connected up.

Rik won the fourth game as well, this time by 26.5 points. In this game I established a good moyoon top but Rik got a bigger one in the middle. I note that he also solved the problem he had last session with invasions into a corner structure.

game 5

Game 5 was a tough and tight game. I won by 5.5 points.

 

June 18, 2020

We played 5 and I won 5 last night, all by greater than komi.

game 1

I had a strong opening and maintained a lead throughout the first game, winning by 7.5

 

game 2

The second game was an easy one for me. One note on this one. I stole the bottom left corner. On review it looks like he should have been able to kill me.

 

game 3

The main theme of the 3rd game was my splitting attack on two groups through the centre. Rik saved the bigger group, but killing the smaller group was also huge. I won the game by 8.5. It’s hard to win when you’re busy defending your groups. He did well to keep it close.

game 4

I attacked Rik’s group on the centre left, destroying his eye shape. He defended until the point where it was possible to connect – but when I made the move which allowed me to disconnect his groups unless he connected up right away, he didn’t see it and played elsewhere. It turned out to be a 50 point kill and he resigned.

game 5

In game 5, I made a 2 space high extension in the top left. Rik peeped against it and I was able to gain territory on both the top and side. He should have invaded the 3-3 or attached to the lower stone to mitigate my strength. I won by 11.5

June 13, 2020

Last night I won 3/5 games, giving 2 stones handicap. All the games I won were by a greater margin than the 6.5 points komi I received.

Game 1

I got off to a pretty good start collecting cash along the top of the board. I also limited Rik’s moyo in the top right sector. He made an error, costing him 3 stones (O6,7 and P7) in exchange for S10. A 7.5 point win.

Game 2

Game 2 started out as a close game, but I took a lead and pulled away. Rik failed to see a liberty shortage situation costing him 4 stones in the bottom left. A 29.5 point win for me.

Game 3

Rik had a really good opening and kept a lead throughout, winning by 8.5 points

Game 4

I thought I was ahead enough to win in Game 4, and didn’t see any aji about, but Rik saw it and was able to create the ko in the bottom left area you can see in the diagram. I couldn’t win the ko. He ate up just enough of my territory to win by half a point. In review, Rik found a defense for me to his whole sequence which would have been successful. Too bad I couldn’t find it during the game.

Game 5

Rik had stones in danger on the 13th line on the right. He decided to run them out and was successful, but the cost was giving me territory as compensation. I won by 12. 5.

June 9, 2020

We played 5 games last night online, 2 stones, 6.5 komi again – I won 3. Four of the games were close. I won the first by 3.5 points.

game 1

I was behind for most of the second game, which Rik won by 5.5 points.

game 2

In the 3rd game, I tried an unusual opening, ignoring the open corners initially and approaching the handicap stones. Mostly I was trying to give the game a different look and find some different ways to complicate it. In retrospect it was not the best opening, even if it wasn’t a disaster. In the middle game I attacked a 9 stone group just above the centre. Rik defended then I attacked the 30+ stone group below it, cutting it off and killing it. The kill was more than decisive, worth over 70 points. Rik should have given up the smaller group and defended the larger one. He would have been a little behind but it was a game. I think attacking multiple groups or attacking one with an eye to targeting another is a path to success.

game 3

Game 4 was one of those unusual games which turn out close even though there is a lot of territory involved. I find these games difficult to get my brain around. Rik won this one by 1.5 points.

game 4

I won the fifth game by 8.5. I was able to steal the top right corner and also mitigate his strength on the outside of it.

game 5

 

June 5, 2020

We played 5 very competetive online games last night. It started with a disastrous game for me. Rik played a strong opening. I misplayed the corner and was faced with Rik having lots of strength outside + a large moyo on the lower right side.

game 1

I tried to kill some of his stones and reduce his moyo at the same time, a strategy which he showed me was highly unreasonable. He killed my stones sharply, leaving me with an impossible game, which I resigned.

In game 2, I stone Rik’s top right corner fairly early on. He tried to convert his wall into some territory right away, but I found a way in and erased his potential.

game 2

This left Rik with a wall across the centre that was alive but floating. I got great territory on the right side and pretty good on the left, plus I was able to burst down through his territorial framework to the bottom. On review, it was clear I got away with about a dozen points more than I should have. I won the game by 18.5

The third game was a good tough close game, which he won by 3.5. I started this one with a 3-5, but Rik pointed out I haven’t been very successful when I’ve tried this opening in the past.

game 3

Game 4 was a bit of a rollercoaster. I started with a 3-3 and Rik echoed that play in the opposite corner. I killed 7 floating stones in the middle nicely, but Rik caught up by killing what I had thought was my corner on the bottom right. I counted and realized I was still a bit ahead and managed to maintain that lead for a 3.5 point win.

game 4

In our fifth game, I started with a high 2-space enclosure in the top left. Rik staked out 3 corners but my corner was a better size. This game featured a big endgame ko. Hi might have been able to pull off a victory by winning the ko, but unfortunately for Rik, I had more ko threats and won the game by 5.5.

Overall, I though Rik’s play was tougher than it has been and I needed to komi to win more games than he did last night. In particular, I felt he was playing more ambitious openings and I had a difficult time targeting his groups and dictating direction.

game 5

 

June 1, 2020

I had a good session, winning all 6 games.

game 1

Rik played a stone into my strength at the top. The result was that he played 44 stones in the top left quadrant of the board for only 10 points of territory. I think for Rik to start beating me at this handicap he needs to worry less that I might get some territory somewhere on the board, and concentrate more on making good positions for himself, and concern himself with reducing me later in the game.

game 2

Our second match was a good tight game. In this game, I played a kakari against his top right 4-4, then left it and played elsewhere. Rik ended up playing 3 stones against this one stone, to assure its death. For future, I want to think more about how I can play this kind of aji stone that he cannot ignore. The question is, how much value can I get by sacrificing a single stone. If it takes 3 stones to kill it, it can be really good value.

game 3

Rik made a big moyo with plenty of real territory along the right side – 60 points worth. I did quite well elsewhere but was still a little behind. I needed to gain something somewhere. I needed 2 moves to kill Rik’s bottom left group. I made the first attacking move. He had to give up some stones to protect the rest but didn’t. After my first attacking stone he could not kill it with one move so I was able to play the kill stone on the bottom, winning the game by 43.5 points.

game 4

I won this game by the value of komi, 6.5 points. In the top left quadrant, Rik has again used a lot of stones for little territory – 56 stones for only 8 points. I think he has to figure out ways to make his stones work harder for him.

game 5

This was a fairly close game – I won by 8.5 points, but it was one with a couple big territories. I had a good top left corner and made it 3 -D. Rik had a good top side but I was able to range out to keep it flat. We both felt Rik was a bit behind through much of this game.

Game 6 – no screen shot. I won by 13. 5 I was able to make territory at the top left and along the left side early. Rik had potential on the top but I was able to keep it under control.

May 29, 2020

We played 5 games last night. I won 3/5 – but game for I won by just a margin of 1.5.

Game 1

Rik played a very solid game, with 2 really good corners + we ended up sharing the top left, which I had staked out. I did very well in the bottom left. I sacraficed the 3 stones at the bottom on the F&G lines and in exchange stole that corner. It was not enough to win, though and Rik took the game by 14.5

Game 2

I won the second game by a comfortable 12.5 margin. This game involved a ko, one which could only benefit me. Rik won the ko, but it enabled me to make gains elsewhere.

Game 3 was one-sided. I won by 90.5.

game 4

Game 4 was a good close game. Rik thought he was ahead in this one, but I won it by 1.5.

game 5

In the final game, Rik carved a huge swath down the centre of the board, killing 3 stones in the process, winning by 20.5. I missed an opportunity to take advantage of a weakness on the right side. I didn’t see it at all, and Rik pointed it out during review.

May 24, 2020

Last night we played 5 online games, of which I won 3. Both of us make plenty of mistakes during these games.

game 1

In the first game, Rik got off to a disastrous start. He allowed me to surround him in the bottom right corner and kill off his group. The ugliness continued as I picked off another 6 stones on the bottom. He was trying to make a big moyo on the top right but his wall wasn’t facing any strength and it wasn’t difficult for me to negate it. Easy game for me, and a 32.5 point victory.

game 2

Game 2 was close – I won by 5.5 points. The critical point in this game was when I pressured Rik’s centre group at move 85. He defended and I used that stone to kick off a reduction of his bottom right territory, bringing down to just a dozen points.

game 3

Rik dominated the 3rd game. He build a lead and maintained it. I was desperate to find some way of pulling a rabbit out of a hat. I tried an invation on the bottom which failed. Rik made a seki in the bottom left. He won by 15.5.

game 4

I won the 4th game by 8.5. Rik made a slow opening, playing a 3-3 under his 4-4 in the top right. The indirect result of this was a good top left corner for me. I did well reducing his potential in the bottom right outside of my corner. Late in the game I blundered away 4 points but I had enough margin of victory to withstand this.

game 5

In game 5, I made an error responding to a peep in the top left. This left him with both the corner and a position on the outside and it put me behind. Had I responded correctly, it would have left him with a lonely stone on the outside. I felt all was lost and was ready to resign. In fact I was so ready to resign I didn’t even see Rik’s huge blunder, neglecting to connect at K13.

May 20, 2020

We played just 3 games last night, and had to stop due to a problem with the server, which froze and locked us both out.

In game 1 (no screen shot), Rik misplayed the bottom right corner and I would up with corner territory I had no business having. I think the real key to the game though was my reduction of Rik’s moyo in the bottom left. I won by 14.5

Game 2 was a wacky one. Rik had a weak group on the top of the board and when I pressed he ran out. I tried to right straight out on the right of him, destroying his potential and take profit on the left. On reflection, I likely ran him out further than I should have, but I could taste blood and could not resist trying to kill. The game got interesting on the left side. Rik needed to reduce my moyo in a big way to win after being attacked. He played 2 light stones. My usual inclination would be to split his stones and pick off one or the other of his groups but I wasn’t sure I would get enough territory to win, so the big kill follies continued. I played lower on the board to try to push all his invaders into my strength and kill everything.

game 2

As seen in the diagram, I killed Rik’s stones and won by 29.5 points. During the review though, Rik came up with a beautiful tesuji that would have killed my stones k12-15, allowing his group to survive. It would have won him the game. Neither of us saw the tesuji during live play. Too bad for Rik, because it was beautiful.

game 3

Rik was tracking to win the 3rd game. About the only way I could win was to kill his 2-space extension along the left side. I was successful in doing so, but only because Rik made a reading error. We both recognized the gift he gave me. I took this screen shot during the review. This is after his error, just when the server froze us out.

I won all 3 games last night, but I needed Rik to make errors to do it. That too is part of the game.

May 17, 2020

We played 7 games in a highly competitive evening. I won 4.

 

game 1

Rik played a solid, steady first game. I found it difficult to destabilize his positions. There was no need for him to do anything extraordinary. I made a 9 point endgame error, but Rik’s margin of victory was 12.5

game 2

Again, Rik played solid and steady. He secured a really good right side and 3 of the corners, and won by 10.5

game 3

In the 3rd game, Rik took top territory and I made a good outside wall. Rik invaded deep. I pressured his stones and took decent left side territory. I also had a strong position on the bottom which translated into about 40 points of territory. I felt I played a more dynamic game this time, and won by 9.5

In the 4th game, Rik played a different variation when I dove under his 4-4 points. He was concerned that I was playing 4 stones underneath, just enough for life, then peeping on the outside. He played to protect the peep and I was able to curl up around the side of his position. I think he was better to not allow that as the peep is not unmanageable.

game 4

 

game 4

In game 4, I opened with a 3-4, then grabbed two other corners. I took a lead and maintained it, winning by 13.5

game 5

Game 5 was tough and tight, and we both fought for every point. I had the tiniest of an edge and won by half a point.

game 6

Game 6 was another very close game. I had a bit of a lead into the endgame when Rik came up with a game-winning endgame tesuji, killing 4 stones. He found a second one as well, exposing another weakness in my position, but the second time I survived. On review, we found a way he could have killed more stones. Rik won by 4.5 points

game 7

Our 7th and final game was the only game which was fairly easy for me. I opened with a 3-5 in the lower right. Rik played a cross-cut. The result of this was that he got a modest corner and I contained him. I started making really strong structure facing the centre. Rik dived in and I attacked him. His main group survived but the cost was great. I killed 2 stones on the right sied and got territory all around his centre group. I won by 23.5.

May 13, 2020

We played 7 game, of which Rik won 4.

game 1

In the first game, I wasn’t able to attack Rik’s top group effectively. He played solidly throughout and won by 15.5

game 2

The second game was very close throughout. Rik’s endgame tesuju at L15 sealed the deal for him. He won by 1.5 points

game 3

In the 3rd game I took two corners by invading the san-san, then successfully attacked and killed Rik’s group on top. A 20.5 point win.

game 4

Game 4 was a tough close game. Rik got a bit of a lead and hung on. I made an endgame blunder in my desperate effort to make something happen, lost some stones and resigned. The game was Rik’s in any case.

game 5

I opened with an unorthodox 5-3 to give the opening a different look. In the bottom right corner, I blocked the escape route for his stones then killed with Q2. On the top, Rik managed corner life under my moyo. Rik made a small endgame blunder which was just enough to cost him the game. I won by 3.5

game 6

In this game, I had Rik under a lot of pressure in the bottom right quarter of the board. We played 2 kos in that area. He saved both groups but at some cost. I was able to encroach his big territory on top and lay wasted to it. As well, I was able to kill off quite a few stones above the two groups in which we fought the kos. Sometimes keeping attacking pressure on is successful even if you don’t kill the target and this game is an example of that.

game 7

I opened with the 5-4 again. This was a very equitable game. I needed to reduce Rik somewhere on the board to win – he took this one by 6.5, exactly komi.

May 8, 2020

We played 6 games, with Rik receiving 2 stones, komi 6.5. I won 5.

Game 1

In game 1, Rik had a weak group on top, which I chased toward the centre. This group finally died, as did Rik’s group in the bottom left corner. Easy game for white. This was a strategic problem for Rik. He tried to have his cake and eat it too, grabbing the top left corner and having a presence on the top side. He would have been better to get a base on the top side and cede the corner or go for a bigger corner and give up more of the side.

Rik took big territory on the right side in game 2. I had opportunities to invade and disrupt it but instead I played to take some territory along the bottom and reduce some of the bottom right corner. Rik’s territory was overwhelming and he won by 25.5

Game 3

Game 3 was an 18.5 point win for me. I did very well hemming him in on the bottom right and getting some territory on top of his corner. As well I reduced his bottom left territory quite successfully.

 

Game 4

Game 4 was defined by the killing of a huge group of Rik’s stones in the centre. He had numerous opportunities to take a second eye, but failed to do so, giving me an opportunity to kill the eye and the group. The game was Rik’s to win had he kept his stones alive.

Game 5

Rik was ahead for much of game 5. There were two key moments. In one I was able to atari a stone and reduce Rik’s territory in the bottom left. As well, I threatened 4 stones in the centre. Rik misread the situation and thought he had to let me take those stones or risk a greater loss. When we looked at it on review, there was no way for me to damage his position if he saved his stones.

Game 6

Game 6 was equitable through much of the game. I converted a good column of territory from centre to bottom and I think that was the difference. I won the game by 11.5 in a game in which I took 6.5 komi.

Overall, my reading was sharper than Rik’s in this session. He made some reading errors which cost him a great deal.

May 5, 2020

We played 7 games. Although I won 5 of them, it was not indicative of the level of competition. Three of the games were decided by a total of 6 points.

Game 1 was tough and equitable. I won by 3.5. Komi was 6.5.

 

Game 2 was defined by play in the bottom left corner. Rik defended the corner incorrectly and I immediately cut. The capturing race led to a 2-step ko. I not only won the ko but also penetrated Rik’s line of defense in the top right.

Game 3 was a solid 25.5 point win for Rik. I misplayed the top right corner. Instead of invading, I should have approached from the outside.

I played the bottom of this board poorly. I played a splitting move that was not sente and Rik was able to press against it and develop big potential, then made a huge move to convert it to big territory. I wound up resigning.

Game 5 was an excellent, tight game. I managed a half point win.

I stole this game by 2.5 points by making a late-game kill of some of Rik’s middle stones. Rik failed to see the kill move coming up and misplayed his defense. I had 4 stones in atari and allowed Rik to connect them up. I should have killed those 4 stones because I had no business being successful in the larger kill. Still I found the sequence and it won me the game.

Rik got off to a bad start in that I trapped and killed 14 stones on the top left early on. That gave me over a quarter of the board in territory. I won by 48.5.

I would say based on this evening’s play that we’re fairly even at 2 stones right now.

May 2, 2020

Tonight I gave Rik 2 stones. We played 6 games and I think to the surprise of both of us, I won 5 of them.

Although I gave up 2 stones, I took 3 of the corners in this game. Rik took a good side that flowed to the outside of my bottom left corner. I created a wall against his side and the game became all about what happened on the other side of that wall.

Rik had stones on the top and a lonely stone in the centre. He tried to save all of them. I split the groups and was able to deny them eye-shape and killed over 20 stones. The margin of victory was 68.5.

In my view, Rik had to give me something in the centre. For instance, he might have given me a stone or two to gain time to make shape for the stones on the top.

 

In the second game, Rik ran a weak group to the centre. If it lived, I was left with little potential for territory. If I killed it, I could win the game. I chased his group toward the centre, then changed direction and played a move to secure a little bit of territory on the left. On review, It seemed that was a slow move. I thought if I capped his group instead, I had a good shot at killing them, but when we played through variations during the review, I was unable to kill his centre group. I have to conclude then that running them to the centre was not the right direction. This was a strong win for Rik. I was forced to resign.

 

Game 3 was a tough and exciting game. It was quite close until Rik initiated a ko by playing atari against my first line stone at P1. He didn’t want to allow me to push in and eat up a couple points of territory in what was a close game. I played atari against his attack stone and we were into a ko. I had plenty of large ko threats, won the ko and advanced into his corner. At this point I thought the game was locked up. I ended up winning by 30.5.

Another interesting sequence occurred after this. I found P9. This was a troublesome move because I could also atari the stone at P8 + threaten to cut off and kill all his stones on the 10 line and above. I think he should have Played Q8 to defend, giving up a little space. Instead, I was able to make life-shape in Rik’s area. The game had already been decided, but it was still a very interesting situation.

 

Game 4 was defined by 2 kills. First I killed Rik’s stones in the bottom right. He had started on the 3-3 in that corner. How did he get killed?

I split Rik’s groups on the top and left, then attacked the left side group by throwing in to force him to take a single eye, then denying an escape route. In review we looked at an alternative line of play for Rik on the left side, in which he gives up a stone and in return gets to run lightly to the centre. I think that was the best approach for Rik, but he was not convinced in review.

 

Game 5 was a tough and competitive game. I needed to convert the centre into territory to win. I had a strong sequence defining the boundaries on the right side of my group, then made the knight’s move to K7 to secure my territory. I wound up winning by 9.5

In our final game of the evening, Rik created a moyo along the bottom which promised him quite a lot of territory. I was able to run some stones along the 5 line to limit the extent of his territory some. I was also able to secure a kill agains his stones along the top left of the board, and with the strength I had from that, I killed the stones he tried to drop on the other side of my guys. Rik resigned.

April 29, 2020

We had a scrappy session. Although I won 5 of the 6 games, they were almost all very competitive. Next session I will give Rik 2 stones. This will test the edge I’ve had in recent weeks.

  1. Our first game was very scrappy. I had Rik’s stones under a lot of pressure but he held his ground. I won but by only 5.5 points.

2. I played white. I thought this was a tight game with me ever so slightly ahead, when Rik found some weaknesses in my position and suddenly he won decisively.

3. I played black and won by 12. 5. Rik had a dragon along the 8th line he had to survive. That allowed me to enhance my territory on both sides

4. I played the sanrensei fuseki (3 star points) as black and Rik played two sansan (3-3). I was able to kill two groups and force a resignation.

5. I played white. In this game I was able to kill a significant group in the lower right sector of the board and won the game by 29.5

6. I played black. Tight game. I won by 4.5. Critical to my game was the kill of 8 stones in the lower right.

    You might be able to upload the image by opening the app, going to the user tab, click view user’s info, then type in your user name, go to the game you want to see, right click it and then choose option see in help room. That will show the completed game. If you can get an image of it from that, i cannot be certain, but i would imagine so.

  2. vox kadavergehorsamkeit

    Not that it matters a great deal, but my notes tell me we played 6 games last night, not 5. And we also got in 6 games on Monday, the 31st with the final one the first back at even strength.
    i must say, it is good to be playing at even strength again. It makes for a different game, or, at least, different approaches. i can’t recall either of us playing a 3,3 with one of our first 2 moves or you invading a corner with the 3,3.

  3. vox kadavergehorsamkeit

    i could be mistaken, but i am reasonably certain that the images posted for the 16th are actually of our games on the 13th. Last night i won the first, 4th and 5th games and in the last pair you had very few points on the bottom half of the board (even fewer than in the posted diagrams.)

  4. vox kadavergehorsamkeit

    Reviewing the first game, i am pretty sure i responded incorrectly to your invasion at G-11. i should have played at H-11, thereby connecting my 11 stones. That would have left you with G-10, a double atari, to which i would have responded at H-9. (F-11, atari on the single stone would not have worked, as i would just connect and have 2 eyes with the group.) The kill of the single stone along with the shared liberties would have been a 6 point gain for you, not the 29 we figured it to be, so still more than i could have afforded to give up, but only a 2.5 point loss, not 25.5. But good for you for battling back in a game in which you seemed to have almost no chance. Win, lose or draw, it was the most interesting game of the set.

  5. vox kadavergehorsamkeit

    Very nice. This will be really good for recalling how games evolved.
