I've been thinking of the assessment bit a little bit more. I found this website: http://gustav.ml/counting

When it's in an endgame situation, I don't think I'm terrible at counting, necessarily. According to that site, I can usually get the right answer in around 40~60 seconds. I could improve speed, I suppose. But I feel like there's more to evaluation than just counting.

The evaluation of whether a result is good for black or white, for example. Part of it is the territory, and part of it is something else - intuition or an idea of how a particular shape, influence, or arrangement of stones... thickness. These types of concepts are hard to encapsulate in simply counting.

What I'm aiming for is a way to isolate this evaluation sub-skill of go in some way such that I can practice it. Bill's series where the AI thinks one side is ahead or behind might be a good start. Maybe I should get some collection of problems like this, and practice them more.

Another game on Fox. I tried the gospel, again. This heretic was crazy. Maybe that's not a nice way to put it... I was surprised by some of the moves.



Biggest takeaway here, I think, is just that I was too confident and answered here too quickly:

I wouldn't even call it a misread, because I played on instinct and didn't read it. I think it's a reminder that I need to be careful, even when I've established some confidence.

Some exercises about position 3:

1. Suppose White gets the entire top as 3rd line territory and Black gets some whatever reduction stones. Who's ahead?

2. As above, but 4th line territory.

3. As above, but 5th line territory.

My evaluation:
My evaluation is that the game is even to slightly good for Black if White gets the whole top as 4th line territory.

Reconsider position 5 in this light. What have White and Black gained since position 3?

My evaluation is not as optimistic, and now I'm curious where my thought process differs from yours.

Here's how I'd think about it:

White has 25 on top + komi = 31.5 points

Black has 28 points, plus the potential to attack the marked stones.

If white has 4th line territory:

White has 9 more points on top, so it'd be 40.5 points.

If it's about even or slightly good for black in this situation, that'd mean that the attack on the two white stones is worth a bit more than 40.5 - 28 = 12.5 points.

Marking the intersections as I have makes sense to me. Evaluating that extra 12.5 points is not clear to me at all...

- The black group on the right is definitely worth more than 2 points.
- The bottom left corner will probably be Black's sente endgame, because White's weaker on the left.
- The white two stones on the right are going to be some kind of liability.
- Black has potential on the bottom and White doesn't.
- The top left corner is counted slightly better for White than it should be; if Black gets the 2-2 point, he gets 3 points and White loses 4 compared to your count; if White gets the 2-2 point she gets ... (1 1/3?) points and black loses 1.5.

The biggest thing is that the top is really all the points White is going to get this game. There'll be 5-6 points from the bottom left group, sure, but there's no other points on the board. Black has lots of areas to make more points.

Cool... Those points seem reasonable. How many points do you think the black group on the right might be worth, if more than 2?

Re: Kirby's Study Journal

I'd give it 5-6? 5 if i'm feeling pessimistic, 6 if i'm not.

Sore throat today, so I didn't play at lunch. Also, I have an AYD game coming up in about 30 minutes anyway. Thought about canceling, but there's no guarantee my throat will be better later this week anyway. So I'll just try it.

Hopefully not COVID-19 :-p

I'll post here when the game is finished.

All I can say is that I got lucky here. Very, very lucky. My sore throat is gone, though, so that's good. Maybe it was psychological :scratch:



Gonna go check out Inseong's review for now... Way too much risk in this game.

The marked move above feels nice to play, but maybe against gospel. I wouldn't say the bottom is an *urgent* situation, so probably I should protect the 4-4:

Somehow, the result in the top left seems decent for black. It's hard to say that I came out ahead there even though I played first. Not really sure what's best there.

Not exactly gospel, persay, but it seems like a nice move. And it's still not continuing locally, which seems to be a big problem with the move I played.

I've seen this before, but it was off my radar during the game.

This trade seems to be a major problem. My thought is that this could sometimes work on other board positions, but here, the top is important.

Still waiting for Inseong's review. I'm last today.

Inseong's review showed some of the many ways black could have easily won the game.

For me, his biggest point was this:

I played the pincer because I felt behind. He agreed I was behind, but he said that I turn on this "switch" too quickly. He said to wait a little bit longer before turning that switch on. That might improve my chances that something will come my way.

This is very interesting to me. It's one of my biggest problems. It's made worse by the fact that I tend to count pessimistically (give myself slightly too few and my opponent slightly to many points when counting), so sometimes I turn on that switch when I'm not even behind.

I haven't worked out yet how to psychologically prevent this. My desire not to fall into passivity is very strong!

( Hi, Graham! Welcome back. )

For me, I over estimate. I'll cruise through an even endgame, thinking that I'm ahead, then find that I lost by 3.5.

I try to compensate by fighting for every last point because I'm unsure. Then I find my opponent is offended because I piled on, fighting the 1/2 point ko when I was fifteen ahead. :oops:

As much as I hate studying endgame (actually, I don’t know why that is; I majored in math as an undergrad, and I like numbers), maybe one way to psychology beat this would be to ramp up skill in the endgame. Then, in cases where I’m behind, there may be some source of psychological confidence: “Well... you’re ahead now, but we haven’t gotten to the strong part of my game”...

Not really sure, though, because this is obviously a problem I have yet to overcome.
