B Q M 11
   

[Diagram]
Diag.: A game of Go Seigen

At move 32, White (Go Seigen) decides not to cut at A, presumably because the atari of Black B and the ensuing awful shape is intolerable. Is there anyone out there who can read out the fight ? Question 1: who wins the semeai if White cuts regardless ? Question 2: even if White wins it or if he can't read it out to the end, is it preferable not to cut but play calmly in order to maintain pressure ? Question 3: what would you do instead of cutting ? (= Where did Go play - not too hard to guess).

--Dieter


If black is concerned only with living, I think he can do so fairly easily by playing c and d in sente, then making his second eye on the edge. If white tries to resist, I think she will lose her corner.

Diag.: Life at all costs

(unkx80: Black 8 can play at 10. And it's much better this way.)

Diag.: Living all right

So, if White keeps up the pressure with 7, Black lives with 8 in sente, and then connects at 10 to put the left side group in great danger. Yes, this seems intolerable for White. So, let's go back a bit. What if White doesn't defend at 5: give up the marked stone in exchange for having shut in Black. Too much of a loss ? --DieterVerhofstadt
