Test your chess: Reitstein problem 166
Black to play and win
White has just played 1 Qd2*Pb4
T Buttress v M Levitt 1985
Solution
A nice puzzle. Had I been playing black in a game, I might not have noticed that there was a tactic on; though if I had been true to CJS Purdy and examined all biffs I would have: 1..Qb7! and black wins a piece, since if the Nf3 moves, the Ng2 is en prise.
When checking the position with Stockfish, it tells me that 1…f4! is even better: if white takes 2 gf ef 3 Bf4, then 3…Qh3 is a ruinous entry, with the Nf3 pinned against the Ng2.


Black has 3 rooks!
