Double atari as a tesuji

    Keywords: Tesuji
[Diagram]

White would like to cut off Black with W1 and W3 but when B4 puts a stone in atari and W5 pulls out, the attempt fails. W1 and W5 are cut off.

[Diagram]

Rather than W5 in the previous diagram, the double atari of W5 here is tesuji. A and B are miai for cutting off the big black group.



This tesuji is related to the crosscut tesuji. It sets up a ko lock.
