Benko Gambit Refutation (1.d4 Nf6 2.c4 c5 3.d5 b5 / 1.d4 Nf6 2.c4 c5 3.d5 b5 4.cxb5 a6) Chess Puzzles

In a benko gambit refutation, White aims to neutralize Black’s queenside pawn sacrifice after the defining idea of the Benko Gambit: …b5 and …a6 to tempt White to accept pawns. The “refutation” part means you don’t just win material—you use the extra tempo and central control to make Black’s compensation (active pieces and pressure on the b-file) fizzle. For an intermediate player, the key feature to recognize is whether Black can quickly generate pressure against your c- and b-pawns while your king stays safe.
