Re: [computer-go] Test position set for MC programs
Huh is right. You wrote C2 C1 and so did I, but I somehow did so while looking at C1 C2. I'm not sure how I managed that myself.

After B B1 W C2 B C1 W H3 B G3, w gains about 7 points in the lower right but has already lost like 31 in the lower left, and black wins by 15. Either I'm missing something obvious, or you overlooked that the lower left is not a seki, or something like that.

In 119 black has a serious weakness on the right. Is there any way for black to win after B B1, W C2, B C1, W H3? ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/ ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/

A2, a3, g1, h1, a4, and if white cuts at b4, black captures and white has no ko threats. If white doesn’t answer at h1, black can live in the corner and white can’t live on the left. Gunnar, does this look correct? Yes, and I get the same score as with A3, so it's not even inferior, only more complicated. With the given komi it's also possible to play A2, A3, A4 directly without the G1, H1 exchange but this is inferior in points. /Gunnar ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
