Abstract form

Abstract form  

This is the abstract form of the connection. The marked stones indicate the two crosscuts which connect the unmarked stones and the groups they belong to or areas they influence a and b. Each of the four stones, when absent, indicates the only move with which the connection can be ensured.


Black resistance 1  

If Black plays atari, then White cuts again and the weak diagonal is now short of liberties.

Black resistance 1  

Symmetry aside, Black's only other move is the empty triangle which is obviously caught.



Using the marked stone to achieve the first crosscut in sente, W3 is tesuji.

Game example

Moves 102 to 102  

The W1-W3 combination accomplishes the tesuji.
