BSR 2003 W100 discussion
Charles Matthews In the game Black reacted to with . This gives Black good aji in the corner (in this kind of position a white play at a might well do something interesting, and perhaps could have been played there as a probe instead).
In the game White played now at b, making ugly shape that immediately lost points on the right side. As for capturing Black in the centre, that didn't go well, either.
Dave: How should White answer 6 here? It seems painful for the three stones at the top while also threatening to jump in at a...
Charles I think is called for. After , if Black at a White takes off with b, which makes White c work.
Tough endgame. Getting sente to play on the lower side is very important. But taking some profit in the centre also seems to make sense of White's stones.
Dave: So Black should hane at first perhaps? After White has a problem. If she tries to close the gap with , the atari at makes work.
Dave: Oops! The ladder looks good for White.
