[edit]

Correct solution:

If white plays a, black plays b.. And still alive..

[edit]

Wrong attempts:

a and b are miai.. If black takes one, white plays the other and kills..

The main trap in this problem is that Black cannot play at . Because is a snapback, in that if Black plays at a to capture the stone, then White will capture the Black stones by playing at again. Hence, the black+circle stones cannot be saved, and the whole group is dead.

[edit]

Ohh and why does black need to add a move?

Because white can kill! Black can't play at a! (It'd be self-atari..)
