One-Two-Three example 2
    Keywords: Tactics

An example for the principle at One-Two-Three, from a recent article I wrote for the American Go Journal.

Just escape

Here White must get out to the centre. But it is better simply to play W1, than to play atari on BC.

Not needed

W1 here is poor style. White has lost the chance of a ladder with White at B2, and still must play W3.

Additionally, W1 has forced Black to strengthen BC. The two stones BC+B2 are much stronger than the single stone BC was.

Black's mistake?

B2 here looks like a possible mistake of the same type. Omitting B2 and simply playing at B4 is normally better style in attacking.
