It’s Your Move: daily chess puzzle #215

White to play and win after:

1…Bb2, as played; or

1…Re8

Tringov v Donner, Busum 1968

Solution

1…Bb2 loses simply to 2 Re7! since the Ng6 is pinned to the f7 pawn: in Purdy terms, there is a jumpcheck Qh5-f7+ in the initial position.

After 1..Re8, the motif is overload: 1 Bh6+ Kg8 (1…Kf6? 2 Qg5 mate) and 2 Qf5!! overloads the Queen, due to the back rank mate. Very conveniently, White’s king is on g2, not g1, else the combination wouldn’t have worked.
