Solution

Correct is to play B1 as here (solution given by Kim Seong-june 6d). W2 is considered to be forced.

This makes good use of the marked black stones below, strengthening Black's group in the top left considerably.

In the game

In the real game Black played B1 this way. The trouble is that this play doesn't do anything quite so definite. If White plays W2 in the corner as shown, it is White who is more secure. Later a white checking extension at a will be useful.
