Snapback Problem 31 Solution
    Keywords: Problem

[Diagram]
A threat of a snapback

By playing W2, White creates a 4 point (miai counting) threat of a snapback at a. If Black connects at a then W2 was sente.

Correct local move

B1 is the correct local move. White a then creates only a 2 point miai counting threat and b becomes a half point. White a is not that big, because if Black neglects a White will get only 4 points for two moves, which makes each of the moves 1.0 point miai counting.



Tenuki is another option.

Tenuki

W1, W3 get 3 points in gote since a and b will be, probably, sente moves for black in the end of the game. This is the price of Black's tenuki and it is not large.
