Sunday Problem #63

This is a somewhat more challenging problem featuring a shape that could appear in a real game.

Black to play.

Solution
Failure
Black 1 may look like a promising move, but it lets white live with 2. Following, Black can get 3–8 in sente for a fairly good endgame profit, but this is still a failure because the core white group lives.
Solution
Black’s 1–3 combination is strong; after this, there is nothing White can do to live. 4–8 is probably White’s strongest attempt, but black 9 limits White to one eye.
