Life In 19x19

Played another AYD game just now.

I feel both stupid and angry.

Here is the game:

Notably, the AI pointed out this 60% mistake move:

I was under time pressure, and I figured those stones were lost. I played a few more moves, and counted myself behind. Then I resigned. It seems I still had a winnable position here.

Whatever the case, skimming through the AI analysis, I can't say I was ahead the entire game (though, I was ahead at the end for awhile, up until this move).

Not really in the mood to do more review right now. Just angry.

I guess I'm angry because I spent a good amount of time thinking for this game, and it feels wasted... It's not a waste, I guess. But on the other hand, I'm playing the same kinds of mistakes in my games... So I can't accurately say if it's a waste or not, either.

Whatever the case, it was a break from work, so I guess I can count that as valuable.

Lost another game in the AYD. I think I'll drop for the first time to the B league. It means I'll play on Wednesdays instead of Tuesdays...

Here's the game:

There are a lot of mistakes in this game, but skimming it over with an AI, I want to point out two areas.

First, there's this:

The AI says I've got a solid lead here.

But then I cut and immediately lose a lot of ground:

Furthermore, it's not even a "cut", since white can always capture at the marked intersection. This "cut" was purely emotional.

and ultimately fall behind - dying, in fact.

Overall, I think I am pushing too far without thinking about my own weaknesses.

Ahhhh!

I set the goal of playing every weekday in order to prepare for the Ohio tournament... But that didn't happen. The tournament is this Saturday.

Oh well, at least I can start from now.

I played again on Tygem.

Here is the game:


I won, but it was mostly due to killing something early on. I have a harder time with games where something big doesn't die.

This is POSSIBLY aggressive. Black is relatively strong in the area, so I don't know how much benefit I'm getting.

OTOH, if I don't do that, black can have a pretty strong wall:

Not really sure. I'll review with AI later.

The end result in the game made me uncomfortable.

That's the main thing I'll say about this game. It was not SUPER stressful after I killed the group on the left.

Reviewed with AI. Some points:

As kind of expected, the AI likes the move at 'B' over the one at 'A'. I chose A since the marked stone on the left is high. But I guess AI doesn't really like that variation that often.

That being said, the AI still likes the marked hane. I guess it's no time to be passive here. However, it recommended a slightly different line after black's weird shape move:

The corner should die, I guess. The AI still thinks that white is ahead here, so maybe globally, it's OK. But I'd probably be freaking if my group died in the game - I was probably in byo-yomi around this time, anyway...

All in all, this was a game where I was ahead for most of it. But I've gotta watch out for basic reading like in the bottom corner - even though it turned out OK, I didn't think fast enough to resolve the true status of the corner.

Secondly, that first 3-3 "joseki" doesn't seem to be often favored by AI.

Dropped down to the "B league" in the AYD, due to not-so-stellar performance last month. That means that I play on Wednesdays instead of Tuesdays. The timing is OK, because I need more practice before the tournament this Saturday.

Unfortunately, I heard that my mom slipped on the ice the other day, and needs hip surgery. So I was kind of anxious to hear how that went - usually a safe procedure, I guess. Fortunately, it seems like things went OK, surgery-wise... But maybe it won't be the same for her walking after this.

Anyway, here is the game I played today:

A couple of points that stand out:

Since I am not going to kill the group anyway, this is kind of unnecessary. So I should probably just turn to force:

He's a bit stronger than me, so I'll compare our thought processes.

Not a real quote wrote: Me: "Hmm. Should I cut?... CAN I cut? Will I die? I don't think so... OK, let's GO!"
Him: "Hmm. Do I NEED to cut? Black seems ahead here. So let's not make things uncertain, and just take points."

It's interesting to contrast these different ways of thinking. I'm definitely prone to thinking the way I did in the game. And of course, it introduces risk into the game and gives my opponent the chance to make a comeback. It introduces risk.

His way, on the other hand, is more stable. More likely to win... So why don't I do that?

I think the answer is primarily: I am not confident in my ability to assess the game. I don't vary moves much in terms of "am I ahead" or "is he ahead". Rather, I play with the same mindset throughout the game: Does my aggressive move work? If the answer isn't a clear NO, then I go for it...

The solution, I suppose, is a better ability to assess the game. I *do* perform a rough count. But it's difficult to get a feeling for thickness, etc., to be confident in the outcome in many cases.

Overall, the game is a little sloppy. So I have to tune up my reading more and do more problems before this Saturday.

Psychologically, I should try to have more confidence in my ability to assess the game - consider playing moves for points that have low risk...

That's really hard for me to do, though.

I went to the 2022 Midwest Go Tournament last weekend. I had been looking forward to catching up with folks and having fun. But on the other hand, I also had a feeling that I'd be losing a lot of games, since I'm pretty rusty these days. As luck may have it, I ended up with a decent result: 4 wins and 1 loss. I definitely got lucky, and was totally behind at times in the games that I won. But it was fun pulling through.

I don't record my games while I'm playing, and instead just try to generally remember what happened later. But I guess I'm not strong enough to be 100% accurate with all of the moves. So that being said, here are the approximate records of a few of the games that I was able to have a record of (though, the game record where I played Jerry was given to me by him; he was recording the game, so I assume it's pretty accurate).









From these three where I have the approximate records, I won the first and third, but lost the second. I don't remember the details that well from the second game where it stops, but basically, he killed me.

So now let's talk about some details... I haven't reviewed with AI, so these are just my opinions.

In the game, I was reasonably happy to get the 4 stones above - it's some solid territory. But at the same time, I felt that white's approach move on the bottom was strong. It was strong in that I didn't know of a good way to answer it, so the game didn't go as I had expected.

So what could have happened to prevent this? I suppose I could have played on the bottom first, if I thought that was big. Instead of moving out:

This has the downside, however, that white can defend on the left, so I wouldn't get the 4 stones. I don't know which way is better. But this way may be simpler.

Nonetheless, it didn't go as I had read it during the game, so that's problematic.

That's most of what I have to say about this game.

In the game that I lost, I don't even feel that great about the opening:

Already, I feel like black is being more efficient.

One of the problems with this game is that my recollection is pretty vague from the middle game, so I don't have an accurate picture of what happened. That's particularly bad, since it should be more educational to learn from a game that I lost. I was a bit emotional after losing, so maybe that impacted my memory.

Anyway, I do remember one other big turning point, which was this:

The game record isn't exactly correct in that in the actual game, somehow I had enough stones in the middle (like the marked ones) such that the move at really threatened capturing the four black stones on the left of the extension. Because of that, I really thought, "this is sente". And I figured I'd have no problem subsequently killing on the right.

Needless to say, he didn't care about those four stones, and ended up getting a board position something like this:

and my big group died.

As a consolation, later in the game, I did manage to kill the left stones:

However, it wasn't enough to make up for his huge kill on the right.

This is a game where it might have been good for me to have someone record for me; or I should have remembered it better, I suppose. Maybe I would have recorded it sooner had I not been so upset.

I will review more tomorrow. I don't think it does things justice to rush through the game reviews. I still haven't gathered all of my thoughts on the two games that I've posted diagrams on here.

Something I want to particularly think about was the one comment on this diagram:

Why in the world did I play the marked white stone, above? It seemed almost automatic, and I didn't even think to question it during a review of the game. The AI recommends a move which moves out and seems clearly better:

Why the heck isn't that on my radar???

FWIW, if I understand the AI reading correctly, my move cost about 13 points; and -28.8% for the win rate!

Despite that, the AI puts me at 91.7% win rate here:

So maybe the game wasn't so bad after all, at least up until this point.

In fact, even at the end of the game as I have it recorded, the AI has white at a win rate of 96% or something... I guess I should have known how to live. Somehow the entire right side died, though, so that was the bigger problem in terms of win/loss.

Nonetheless, the earlier part of the game is pedagogical.


Still wondering why I didn't see this move:

It's obvious: move out...

I want to review more of my tournament games, but I have little time. I have lots to do at work, and I need to study for a Korean test that's happening in less than a month. And also trying to learn some other things, which I'm not advertising that much...

So I played another game in the meantime, and did a review:



I played on Tygem as white, and lost by 1.5 points.
