Atari from crosscut

    Keywords: Shape, Tactics

When there are other stones nearby, sometimes the atari is the better follow-up to the crosscut, despite the proverb.

[Diagram]

black+circle influences the crosscut. Suppose development towards the bottom right is important.

[Diagram]

With this atari and connect, White limits the development of the Black stone and she influences the bottom right.

[Diagram]

Of course, Black can thwart White's intentions, but now she comes out with a ponnuki and probably sente, thanks to having given atari.

[Diagram]

Following the proverb and extend in this situation is not bad, but then Black can choose to connect to black+circle. His shape is not bad, whereas W1 looks superfluous now

[Diagram]

W1 here violates the spirit of the proverb as it doesn't gain liberties. Now black+circle is perfectly placed as hane at the head.
