Answer to Puzzle time #3
(as answered correctly by Ian Wallis):
After 1. Qc5+, Black must move his King to b2. If he plays … Kd1, then a quick mate follows with Qc2+ and Qe2#.
Then White plays 2. Qb4+, with Black forced to play … Ka2 (if … Kc1 then 3. Qd2+ and 4. Qc2#).
Now comes the surprising move that wins immediately: 3. Kc2! The Black Queen has no checks (other than kamikaze ones) and White will checkmate next move.
