Can I ask why Kirby's post above is in my "view your posts" list, which normally only consists of my own posts?

Is this an ad, virus, accident, or UFO?

edit: Ah, I probably misunderstood, and any thread I've commented on shows up if updated. Apologies.

I think the marked move, above, misses the point. I should just jump out:

The move above was risky - I didn't read it all out, and if I get captured, I lose points, Counting the board, I think it may not be necessary.

Takeaway: Analyze carefully before taking big risk.

I suppose it's important to put that pressure on, early.

I felt the result was bad for black because of white's influence there. But I suppose the point is, white's influence isn't perfect. If I move out the black stones there, I can negate white's influence in the center.

Neither A nor B would occur to me, for different reasons. I would definitely feel the urge to play with the ponnuki, preventing C, either by playing C myself or D. Therefore I would not consider B because of the apparent urgency of the area. A is a move that goes along well with the 3 black stones below, almost a middle game joseki move, but it's cursing against the power of the ponnuki.

With hindsight, I can see that C is not a very efficient move for either Black or White. Black's ponnuki is too resilient for White to attack swiftly, while building influence towards no man's land. And White's three stones are out in the center, even after Black C.

So I think I understand why AI favors B, which is a rather severe approach to White's corner, while taking a wide stake at the bottom. Probably being a ladder breaker (ladder starting with E) is another added value.

I think you have a good point that 'a' makes the ponnuki a bit inefficient.

Played another AYD game just now.

I feel both stupid and angry.

Here is the game:

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.

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:

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.
