Play Kikashi Before Living

Adapted from KanazawaSolution21.

[Diagram]
Diag.: Correct

White can live with either A or B, but plays kikashi with 1 before living.


[Diagram]
Diag.: No kikashi

If White immediately takes a VitalPoint, she lives too, but now she has failed to kikashi Black. If White plays 3 later in the game, the value of that move is reduced to 4 points and odd, and Black can choose to ignore it. If White eventually captures the marked stones with 5 and 7, Black can make shape with 6 and 8. Also, 1 has now been turned into a superfluous move, a 1 point loss.



[Diagram]
Diag.: Difference

The difference with the correct diagram is that, if Black ignores White 1, then the capture of the marked stones yields not merely 4 points, but also life for the corner. Now look again at the previous diagram, which is as if White plays at A here, in exchange for a Black move elsewhere, really a ridiculous turn of events.

Diag.: Comment

Comment: Depending on the situation, if white plays at 1 alone, then later the peek at 3 may turn out useful.
