Positional Judgement Problem 1 Discussion
From Positional Judgement Problem 1. Chris Hayashida: I listed this as a "discussion" instead of an answer, because I really do not know the right answer to the problem. This page is my explanation of why I played the way I did, and what I was thinking. It might help weaker players see how a low kyu player (4k? KGS) thinks. It also might provide a good laugh for stronger players. I would love to have comments about both my thinking and my play, as I hope to improve both. From my game on 11 September 2003 on KGS: White has captured 9 stones. Black has captured 3. 6.5 komi.
Chris Hayashida: I considered giving up the three white stones marked with circles. Even if those stones were captured, it would only give the black group one eye.
However, giving up these stones would jeopardize the marked white group on the left, though. I needed to capture the marked black stones in order to keep the game close.
Chris Hayashida: I counted the board in pairs, with a result that Black is ahead by four points (two pairs) after prisoners and komi. I counted the upper left, upper right, lower left, and lower right as Black's territory. I also counted the area just below my dead group as Black's territory. I did not count the middle as anyone's territory, since I felt that both sides should be able to connect their stones without too much of a swing in points. However, I felt that Black had many opportunities for reduction, while White did not have any areas where he could make more territory. I thought that if I played passively at A or thereabouts, I would not have enought points to win.
I connected solidly at
Sebastian: Excuse me, I'm only starting to learn Positional Judgement. Is this more or less what you meant? (Black areas marked with dot, white with w. Dead stones marked with ring.)
Chris Hayashida: Before playing the bad shape move
If black plays like this, white cannot defend both a and b without letting black get two eyes (or connect at c), so black has the option to live. This would seem to mean that black c is a serious problem for white. --Bass
