Benko Gambit Exchange Sacrifice Chess Puzzles
The Benko Gambit Exchange Sacrifice is the hallmark idea of the Benko Gambit, usually after 1.d4 Nf6 2.c4 c5 3.d5 b5. Black often plays ...b4 and then sacrifices the a8-rook for White’s a- or c-file rook with ...Rxa6 or ...Rxb2 ideas, gaining long-term pressure instead of material. For an intermediate player, the key feature is that Black gives up the exchange to open the a- and b-files and target White’s queenside pawns.
You should look for this sacrifice when White accepts the gambit and castles kingside while leaving the queenside pawns slightly advanced or weak. The exchange sacrifice works best if Black’s bishops, rook, and queen can quickly occupy the open files and keep White’s queenside pieces tied down. Use it when the resulting activity and pawn targets are more valuable than the rook you give up.
