Benko Gambit Defensive Move in Chess

In the Benko Gambit, a key “benko gambit defensive move” is Black’s practical defense after accepting the queenside pawn sacrifice—most often …a6 and the follow-up …b5 (or …bxc4) to challenge White’s center and queenside structure. The defining feature is that Black uses the extra queenside pawn pressure to neutralize threats while preparing counterplay against White’s pieces and pawn chain.
