TA 1999 Problem 4 solution
    Keywords: Shape, Problem

[Diagram]
Diag.: Solution

White 1 here is a key point of shape. (Solution given by Kim Seong-june 6d.)


[Diagram]
Diag.: Follow-up

With the marked white stone in place White has a very good follow-up sequence with White 1 and 3 here. White has secured the corner, constructed perfect shape, and give 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.



[Diagram]
Diag.: Game sequence

In the actual game White attacked with 1 and 3, but was in trouble after Black played 4.



[Diagram]
Diag.: Game sequence

Obviously White 1 is a good move if Black doesn't answer. The question I have is if the 1-2 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 1) in sente. That means that White can attack more strongly on the outside. I like White 3 as shown, from the point of view of direction.
