It’s Your Move: daily chess puzzle # 158

White to play and win

Pachman v Gunnarsson, Vrnjacka Banja 1966

Solution

Fairly straightforward today. Exchange one pair of rooks, the correct way, and then pin and win. So 1 R6d7+ Rd7[] 2 Qb5 and a rook is won; 2…Re7 doesn’t defend the Qe8 because the Rook is pinned to the King, so the Q is a LPDO. (If instead 1 Rcd7+ Rd7[] 2 Qb5 Re7 does this time defend the Q).
