TA 1999 Problem 3 attempt
As a player around 20k, I'm wondering if my thoughts come even close to dealing with the real question here. But perhaps some of the better players can give me some hints what the real issue is in this problem. If this was my game, I would think that white groups in the lower left corner and on the right side are alive at the moment. The white groups in the left middle and the upper left corner look to me as if they could do with some help or they might forced to live in a cramped space or even killed. The two white stones in the upper right corner seem to me a good enough base to make life or connect to the middle if needed. For black, I'd think, that the stones sandwiched in the lower left corner will be hard to kill. So I think,the question comes down to what side of that group is more profitable for White. With both plays, White should be able to drive Black across the board towards the upper right corner while building a nice wall on one side. The otherside however is probably lost for most part to Black. By playing a, I would guess white will soldify a nice framework on the left and upper side by trying to connect to the stones in the upper right corner. On the lower side, the black territory can be reduced from the 2 groups there. Black could get a good chunk of territory in the upper right and middle. By playing b, White should be able to connect the lower left to the rigth middle group. But I think, the two black groups are well positioned to check the territory. On the left side, Black will be able to put a lot of pressure on the white groups and keep the small. The upper right corner could be forced to make life on its own. Going by that reasoning, I'd play at a. -- Confused: This is a copy of the living page "TA 1999 Problem 3 attempt" at Sensei's Library. (C) the Authors, published under the OpenContent License V1.0. |
