Solution  

This diagonal W1 is a fairly common technique move in capturing races. It prevents Black from playing at either marked point immediately. It requires Black an additional move at a to approach, while taking away a Black liberty. Thus White wins the capturing race by one move.

White wins the race  

This diagram shows how White wins the race.

[Diagram]
Failure 1  

W1 here loses the capturing race. Note that B2 is the only correct play.

[Diagram]
Failure 2  

This fails as well.

[Diagram]
Failure 3 (B2 elsewhere)  

W1 will be ignored - Black can wait for W3 to play B4 making it a false seki. Because the group of stones containing W3 is dead, so all the white stones are dead.
