Choice of nets



Black has a choice of net captures of white+circle:

  1. Black at a;
  2. Black at b (this looks like a ladder but isn't: if white d then black e)
  3. Black at c.
[Diagram]

Choice of nets (3)

White cannot actually escape with W2 after B1.

Choice of nets (3) (continuation)

After the throw-in B1 here, Black captures the white+circle stones (in a ladder, if White connects at B1).

Of these three nets, one prefers number 1 to number 3 on the choose the firmer capture principle - though that doesn't always apply when building influence.

After choice 2

There is a problem with choice 2, namely W2 after B1. It might depend whether Black actually wanted to provoke the W2/B3 exchange. If so, choice 2 is better than choice 1.

[Diagram]

After choice 1

In this case White has a forcing play at the circled point. This is still a little too close to Black's influence.

The decision may therefore depend on the direction of fighting.
