Black getting entangled in a net

After W2, White can catch Black in a net with W4. B5 and B7 can be exchanged without changing the result.

Correct play for B1

Black should have played at B1.

Correct play for B1

Brent: Then what? How does Black continue after W2?

ProtoDeuteric: I believe that a play next to W2, on the edge, would be in order.

TA: Why not here?

Protect, anyway

W4 at black+circle.

Because W2 will force a protective move, anyway. Even if Black can play B3 - W4 with sente, Black will have to play B5.

OTOH, if Black plays at a, he threatens B2, saving black+circle.

It is a very close call. Depending on the rest of the board, B1 could be better.

See One-Two-Three.
