The "big" stuff that sticks out to me...

Position 1

I don't know much about this pincer, or how to respond to it. I want to press like this:

But I was afraid that black would come back and push through. I vaguely recall a sequence like this:

But checking on josekipedia, it says that's outdated, and to play here:

I will check it with the AI later.

Whatever the case, I felt really bad about this push:

But I don't know the best way to avoid it. Should *I* push there first? That seems bad. But I don't have a sequence that I can find that seems good. This seems like the biggest thing for me to get some ideas from AI.

I will leave it at that for now and check the AI soon.

Checking AI, seems it wants to just tenuki this:

Bigger problem seems to be that it doesn't like my response here:

Instead, just push through:

AI seems OK with getting split here and taking the corner.

This week's AYD game:

There were some mistakes, but after the opening, I felt somewhat comfortable.

Move above is a misread. It's not a ladder breaker. Besides, I have no time to break ladders, locally.

This is the move of the game for me:

Looking through some variations, I might have given up on killing black. And killing black may have ended the game right then and there. But I couldn't read it all out.

So I relinquished a little bit.

My reading was off, but I like the psychology there. Normally, I go for it no matter what when the result is unclear. This time, I showed a little care.

I saw Inseong's review of the game, and there was one obvious bit that was wrong that I missed with the reading here:

You get the picture... So I missed this in my reading.

However, I think my mindset was still OK here, despite that Inseong said that I was not "cooling down" for this move. I believe I played rationally, thinking of several variations. I didn't consider the loose ladder, which is a reading weakness. But I was not playing aggressively just to play aggressively, which has been my problem in the past.

I played a rated game on KGS for the first time in a long time. I did automatch and was paired against a 1d - I personally think he's stronger than that, because he hasn't played that many games.

Not really sure, but whatever the case, I got destroyed.

Here is the game:

I also noticed for the first time today that KGS has some sort of AI graph after the game... Kinda cool. Looking at the graph, I saw the lead from the no komi at the beginning, and later saw the graph drop. I don't want to pay too much attention to the AI, yet, before I think about the game myself a bit more.

So what went wrong...?

Things started getting complicated around here:

Incidentally, I just heard about this sequence from a guy I played in Ohio. According to him, black can play the move I played. That's where I got the idea for it.

Locally, the obvious shape weakness is if white plays here:

But I'm thinking, during the game, if white plays there, I can do this:

I lose a stone, he loses a stone. Seems reasonable.

But then what if he plays here?

Immediately locally, it seems like a conundrum, because white has some forcing moves:

The weakness at the marked area doesn't seem great... But it's OK, because I can play the ladder:

So seems OK. I proceed with the game.

Just a couple of moves later, I've moved on a bit, and he peeps:

Seems like just responding's gotta be the best thing locally. But then, that screws up the ladder I was thinking of:

Doh.

So this was the first real problem where the game didn't flow the way I expected it to...

Why is that?

Potential reasons:
(1) I played something complicated that I wasn't familiar with.
(2) After reading locally, I stopped thinking about it after the board position changed.

Here's another one:

I knew I could surround the white stones like this. I even thought about the position that resulted from the game. But somehow, I didn't think about the fact that I wouldn't have enough liberties.

I felt the general position thinking ahead, but my awareness of the resulting liberties was bad.

As a result, I ended up here:

Alas, white has 4 liberties, and I have only three.

Later in the game, there are some minor reading mistakes, but psychologically, I've already fallen apart by now. I played aggressively to try to catch up, but it was no good.

Maybe a better strategy would be:
* Stay calm, though behind, and wait for an opening. Maybe there'd be another chance.

Just trying to push through aggressively after feeling behind made me overplay more and fall further behind...

So what are the overall takeaways?

(1) Reading mistakes were costly.
(2) I should investigate the pattern with that one space pincer.
(3) When behind, be calm and endure...

Problem with #3 is that sometimes my aggression works and I can make a comeback. I actually don't know what the stats would be if I compare post-screw-up aggression vs. post-screw-up calmness.

But given that I'm already on the aggressive side, maybe toning back wouldn't hurt.

37 was a special move, which turned out badly, so the question is why not extend until it's gote and then tackle the corner. My gut says you win that fight.

65 was - with hindsight better placed at the turning point in the center, which would also have been sente, then you can attack the left side with a keima check.

Yes it was a battering but mostly a one way street from these moves. Some calibration of the fighting is due. Nothing to be ashamed of.

Thanks for commenting, Knotwilg. It's nice to have some dialog here.

I'm in agreement with both of your points.

I feel bad crawling so low with 37, but white is still weak in the corner, isn't he... If I get the corner, and white gets the outside, I suppose it's not so bad.

I can feel your comment regarding 65 even more strongly. The center was really important, and white breaking through was a disaster.

Regarding this one:

(2) I should investigate the pattern with that one space pincer.

Maybe it'd be a good idea for me to try to play this pincer in upcoming games to try to force some experience with this pattern... Just have to remember that next game.

AYD game from today... I was black, and I got killed.

Clearly, I misread some things. Somehow, I still enjoyed the game. I didn't like dying, though.

Here's the game file - a few comments on it shortly.

Some thoughts.

Position 1
Maybe this is too far:

I say that because the sequence that happened next seemed pretty nice for white.

Both 'a' and 'b' seem like decent places for white. If I extend, I can't say that I love it for black:

Yeah, his cutting stones are weak... But I haven't captured them, yet, and look at that territory that he got!

And when I protect again, like in the game, it seems overconcentrated, giving white the nice extension point:

So it makes me feel that since I'm fighting with his cutting stones here, let's just be strong to begin with:

More solid, and the capture at 'a' doesn't seem as good for white.

Seemed reasonable, at least, to me.

Of course, his response put more pressure on the left group:

At this point, I think I played too aggressively. I didn't want to submit - "hey, he put a weak group in MY area!" was the thinking... But perhaps it's best to just move out with him:

Not great that he moves out, but hey - at least his group is still weak.

But no... I am too stubborn for that. And the sequence to follow hurt:

So the conclusion is:
(1) I tried to be forceful since it was in my area.
(2) I was too weak, and I snapped.

After this, I died. The remainder of the game is not super meaningful, because I was trying to simply catch up. So I don't want to focus on that part so much.

The takeaway from this game, I think, is... When things aren't going the way I want them to, I need to read things out and relent if the position is not looking good for me. Otherwise, I'll snap like I did this game.

However, I have a really hard time doing this. If the opponent invades or something and I am not getting sufficient profit because of a mistake that I made... I have a really hard time easing up to wait for another chance. It's really hard for me, psychologically. I feel some amount of pain in letting up.

This is a common story for me, but due to the emotions there, it's hard to let up. Hopefully, I can look at the board more objectively.

FWIW, KGS AI seems to think I am ahead until this move:

It says -70 there. Instead, it proposes this:

But maybe more educational is the follow up that it proposes:

Perhaps because of the ko threat the AI suggests, white can't hane:

Since there's aji in the marked area for the cut...?

This is just my guess.

But what I also want to take away from this was that the AI was OK with me not directly sealing white in:

I think this gives credence to the idea that I need to look ahead and relent a little bit if I cannot force the ideal position I wanted.

Can you explain the thought process behind this move? Even in retrospect you don't seem to think it's a weird move, so there must be something that makes it look playable in your eyes (while in mine it's a nonsensical novice mistake). An artefact of liberty reducing throw-in tesuji perhaps?

Edit: sorry, now I see it. It's a ko threat!

Yeah, the intention was a ko threat. But the AI seems to think that this one is much better:

In the game, I actually considered the suggested ko threat, however, it seemed more possible that white could ignore it... But this WOULD be pretty big for black:

I suppose after my ko threat, white is pretty strong and there's less aji:
