Summary
The Benko Gambit arises after 1.d4 Nf6 2.c4 c5 3.d5 b5 and falls under ECO code A57. With 3...b5, Black sacrifices a pawn on the queenside, and since declining tends to be unfavorable, White usually accepts with 4. cxb5. Black then follows up with 4...a6, offering a second pawn. If White takes with 5. bxa6, the compensation for being down material (Black can recapture on a6 at a convenient moment) comes in the form of powerful queenside pressure along two half-open files, a strong long diagonal for the fianchettoed bishop on g7, and a healthy pawn structure. White can opt to accept the first pawn but decline the second, for example with 5. b6, to avoid the most theoretically demanding lines. Declining the gambit entirely on move four is also possible but generally considered suboptimal, as it allows Black to advance with ...b4!, seizing queenside space and clamping down on a3 and c3, squares where White's knight would naturally develop. In practice, Black frequently maintains the tension between the b- and c-pawns, waiting to see whether White will eventually transpose back into a Benko Gambit accepted. With 4.3 million Lichess games across all rating levels, it is a well-established opening choice.
- Black gives up a pawn for long-term queenside pressure down the half-open a- and b-files, backed by a fianchettoed bishop on the long diagonal.
- Unusually for a gambit, Black is happy to swap queens - the positional pressure keeps paying off deep into the endgame.
- White's extra pawn comes at a price: the a- and b-pawns become targets while Black develops quickly and plays for a win.
History and Notable Players
It arises from the Indian Defense Systems. Among the most prolific practitioners on the White side are Ivan Farago (54 games), Ivan Sokolov (37 games), Loek Van Wely (35 games). On the Black side, notable exponents include Juan Manuel Bellon Lopez (67 games), Jan Plachetka (66 games), Natalija Pogonina (64 games).
The ...b5 pawn sacrifice was employed repeatedly by Karel Opocensky in the late 1930s, and a 1953 Taimanov-Bronstein game at the Zurich Candidates brought it wider attention. Pal Benko then refined and promoted it from the late 1960s, publishing The Benko Gambit in 1974. In Eastern Europe it is known as the Volga Gambit, after a 1946 Russian magazine article.
Named after: Hungarian-American grandmaster Pal Benko, who championed the gambit from the late 1960s and published a book on it in 1974.
Notable players: Pal Benko, Garry Kasparov, Viswanathan Anand, Veselin Topalov

Common Mistakes to Avoid
- Overextending without backup: When playing a gambit, each attacking move should have a purpose. Random checks and threats without coordination can leave your own position exposed once the initiative fades.
