High approach questionable

When Black plays BC in the left-hand corner, the joseki shown is a very likely consequence, finished by White playing W5 or perhaps one line higher. Then Black has to consider how to play an approach in the right-hand corner. Black a is good.

Black at b, however, is not, by pro standards.

Not good play

With the normal plays to W6, it may seem that Black is doing fine; but where should B7 be? Neither of the points a or b is really satisfactory. The point is that the BC stone is strong, and there is now no play on the side that really makes use of that, and the strong B3+B5.

Disappointing avalanche

It seems unlikely that Black can get a good result by switching into the avalanche either: once W6 is played low and solid, it seems that BC will go to waste as a powerful stone.



This side position came up in this year's Oxford-Cambridge match.
