Black Sheep Rengo 2003

Charles In this position the clamp black+circle takes advantage of White's shortage of liberties, in a standard way. The question is whether White could have avoided this, earlier.

[Diagram]

Assume no tenuki

Suppose that White hadn't played tenuki after B1, but had answered at W2. There is a reading problem here, after B3 is tried.

[Diagram]

Assume no tenuki (continuation)

These plays are inevitable. Then Black has a choice of three directions in which to play atari:at a, b or c.

Black can play at a whenever it seems useful.

[Diagram]

Variation 1

This way Black can break into the centre; but has given away some points on the upper side.

[Diagram]

Variation 2

If Black plays this way, White's shape seems to be good enough after W4. Up to W10 Black can only make a small dent in White's centre.

There are some other variations to consider: but White 112 in the game seems to have been a 'tenuki too far'.

[Diagram]

Variation 3

Black's best line here seems to be this way to play.


unkx80: Argh, yes, it was a reading error on my part. =/

Migeru: Wasn't it I that missed the shortage of liberties? (Sorry, Charles)
