thanks for this Bill, it took me a bit of time, but I see what you mean now. And probably diagram 4 is never better.

The language I use for endgame does seem to confuse myself. It comes from pro commentary estimates, and my own understanding with a rough overview of the theory, whereas your system is clearer, comparing everything to a given zero point.

I can agree that in general your 3rd diagram is marginally better for white than the 4th, but by 1/6. I think you mean that after white a, then c is worth 2 2/3, so therefore a is worth 3 points with a 2 2/3 gote follow up, and therefore is worth 4 1/3 (instead of the 5 I first wrote down). The 3rd diagram is equivalent to if W gets a and B gets c, so this is better by (3- 2 2/3)/2 = 1/6.


There is a lot of rubbish in what I wrote here. It should be:

after white a, then c is worth 4 2/3, so therefore a is worth 3 points with a 4 2/3 gote follow up, and therefore is worth 3+ (4 2/3) /2 = 5 1/3 (instead of the 5 I first wrote down). The 3rd diagram is equivalent to if W gets a and B gets c, so it is better by ((4 2/3 )/2- 3)/2 = 1/3.

Yes, I do think that the usual method of evaluating plays causes confusion. But this is not my system. It uses what I learned as miai counting, what O Meien today calls absolute counting ( 絶対計算 ). :)

final pandanet game, and I've gone all season undefeated, playing almost all matches

this game, my play quality was low, or at least my alertness, judgement, reading were all down due to exam prep exhaustion, just relying on feeling. Also my opponent played well, making a nice plan to attack a weak group of mine (I should probably have sacrificed a large group to save that one) and perhaps it should have died. In the end, I thought I was slightly behind, but score estimate says I was ahead, I threatened a slow ko to kill my opponent's corner. Instead he threw the ko in himself, so I took the ko first for free, he played a fake ko threat in time trouble, and I won.

I made a quick commentary.



And a practical way to avoid the complacency vs Andrew Kay is probably to imagine a significant reverse komi, to keep playing good moves, and still challenge my opponent to think, to still leave a high quality game, than some conservative rubbish.

I just had a good pro game study session. Perhaps with uni pressure and computer go, my creative spirit in go has gotten lost, and I've stopped improving.

With computer go, I've fallen for the trap of thinking learning their ideas and techniques will help my go, when I forget how much of a gap I have on the understanding of every move of high level games and every move they notice but don't play. Perhaps it is also that the high level of judgement and intuition of computer go really brings me back to my ideas of the logic of fuzzy concepts and intuition that I found so interesting before in go. But it turns out to have limited value in improving go skill. I need to put more emphasis improving my personal understanding rather than mimicking high level moves when my understanding of lower level moves is insufficient. I've reduced my leela usage to a minimum, and I should try to think more independently of alphago.

At today's go club, I got the chance to think more deeply about pro moves on a real board, guessing the next move, and seeing how confusing they are, and how big the gap is. Normally I just skim games without thinking too much.

I've looked at the first 30 moves quite in depth and no more. The file size is bigger than my average self-commentary.

Lee Changho plays a very cool new move against Lee Sedol in some Korean cup. I can't find the sgf on go4go yet.

not too bad a game. Looked into move 28 in depth.
