TA 1999 Problem 4 / Solution

Sub-page of TA1999Problem4

W1 here is a key point of shape. (Solution given by Kim Seong-june? 6d.)


With white+circle in place, White has a very good follow-up sequence with W1 and W3 here. White has secured the corner, constructed perfect shape, and given Black serious shape problems on the side.

The recommended answer is an example of a play that is 'almost sente'. It isn't claimed that Black must answer it directly; but if Black doesn't, White has a great deal to look forward to here.

Game sequence  

In the actual game White attacked with W1 and W3, but was in trouble after B4.

Game sequence  

Obviously W1 is a good move if Black doesn't answer. The question I have is if the W1-B2 exchange is favourable for White. Is Black's clamp less threatening now ? --Dieter

Charles So now White has covered the cut (at the point of W1) in sente. That means that White can attack more strongly on the outside. I like W3 as shown, from the point of view of direction.
