The queen's pawn. The flexible knight. The full claim. The Benoni strike. White advances, sealing the center — — and the Benko offer lands: ...b5 volunteers the wing pawn at c4. If White accepts, Black recaptures toward the center over the coming moves and inherits the a- and b-files half open, a fianchetto bishop on the long diagonal, and a queenside initiative with no expiration date. Most gambits fade when the queens come off. This one gets clearer."]]
The Benko Gambit runs on economics no other gambit shares: Black gives a wing pawn not for a lead in development or a mating attack, but for permanent positional pressure — the a- and b-files half open, rooks stationed on them by move ten, the fianchetto bishop raking the long diagonal, and White's queenside tied to defending itself for the rest of the game. Ordinary gambit compensation is a currency that expires; the Benko's appreciates, and the standard astonishment of every student who meets it is that Black's pressure often improves in the endgame, where the queenside targets remain and White's extra pawn is the hardest kind to use.
