Solution.



W1 is the correct solution. If Black moves anywhere except B2, White captures four pieces by moving there.

Variation, worse for Black

If Black captures with the White stone (that had been at a) by playing the marked stone, White plays W1 and catches four stones in oiotoshi (connect-and-die). If Black connects at a, White b catches all 9 stones.
