Benko Gambit
also known as: Volga Gambit
1. d4 Nf6 2. c4 c5 3. d5 b5
Named after
Pal Benko (1928–2019), Hungarian-American grandmaster — wartime survivor, defector, puzzle composer, and the man who gave Fischer his 1970 Interzonal spot.
Origin
Known in Soviet literature as the Volga Gambit (1946 article from Kuibyshev on the Volga); Benko's systematic treatment and 1974 book made it his in the West.
The story
Benko's life outdoes fiction: he survived a labor camp, was imprisoned after trying to defect, finally escaped to the U.S. via the 1957 World Student Championship, and famously gave up his own 1970 Interzonal qualification so Bobby Fischer could play — and win the world title. His gambit is equally generous and equally cunning: Black gives a whole pawn (...b5) for no attack at all, just two open files and an endgame initiative that grinds forever. It is the only mainstream gambit where the gambiteer is happiest in the ENDGAME — a strategic paradox that has never been refuted, only avoided.
Why it matters
Positional gambit par excellence: compensation measured in file pressure and pawn-structure paralysis rather than mating threats. It rewired theory's understanding of what "compensation" can mean.
