The Benko Gambit is one of the soundest pawn sacrifices in chess: 1.d4 Nf6 2.c4 c5 3.d5 b5. Black gives up a pawn to open the a- and b-files and gain long-term positional pressure on the queenside.

The Benko Gambit arises after 1.d4 Nf6 2.c4 c5 3.d5 b5. Black sacrifices the b5 pawn to open the half-open a- and b-files on the queenside. Along them the rooks and the g7 bishop will press on White's position for a long time.
Its defining feature is that this is a positional sacrifice, not an attacking one. Black is not counting on an immediate attack: the compensation is long-term and survives into the endgame. That is why the Benko is considered one of the soundest and most reliable gambits.
In the West the opening is called the Benko Gambit, after the Hungarian-American grandmaster Pal Benko, who developed it in depth. In Russian tradition the name Volga Gambit stuck instead.
In the accepted gambit White takes both pawns (4.cxb5 a6 5.bxa6), and with ...Bxa6 and the fianchetto Black gets the classical compensation: pressure on the a- and b-files and an active g7 bishop. This is the opening's main line.
To avoid opening lines, White often returns the pawn with 5.b6 or keeps things in check with the e3 variation. The most cautious route of all is to decline the gambit entirely with 4.Nf3, never taking on b5.
The Benko Gambit is a rare case where the pawn buys not an attack but a position. After 1.d4 Nf6 2.c4 c5 3.d5 b5 4.cxb5 a6 5.bxa6 Black sacrifices a pawn for two open files on the queenside.
The plan is simple and almost identical every game: ...Bxa6, ...g6, ...Bg7, ...0-0, rooks to a8 and b8, and endless pressure on the a2 and b2 pawns. The compensation does not disappear even when the queens come off - which is why the gambit is equally good in the middlegame and the endgame.
That rare property is what makes the opening special: normally a pawn is given up for an attack that either works or ends in a bad endgame. Here it is the other way round - the simpler the position, the clearer the compensation.
There are three approaches. Accept the gambit and play carefully: 5.bxa6 Bxa6 6.Nc3 d6 7.Nf3, or 7.e4 Bxf1 8.Kxf1 with the idea of g3 and Kg2 - the king walks to safety by hand, but the extra pawn stays.
Declining: 4.Nf3 or 5.b6 - White gives the pawn straight back and denies Black the open lines. The position stays closed and the whole point of the gambit is gone.
Or avoid it altogether: play 3.Nf3 instead of 3.d5 and steer the game into other structures. Practical advice: if you do not know the theory, declining is safer than accepting - holding the pawn under double pressure on the a- and b-files is technically hard.
The typical set-ups this opening leads to - learn them, and the plan follows by itself.
Black has given up a pawn and traded the light-squared bishops, depriving White of castling. In return: the open a- and b-files and long-term queenside pressure.
These are the main named variations. Click any one of them and it loads straight onto the board above, where you can play it out move by move. The trainer itself holds more lines than this: it also covers main-line continuations and transpositions that have no name of their own.
What to avoid, and what catches an unprepared opponent.
White gives the material back but does not get developed in time, and simply ends up worse. The pawn has to be returned with tempo, not out of fear.
Curling up in defence against the Benko Gambit is a sure route to a long ordeal. White needs an active plan, or Black's pressure never ends.
Traps in other openings - the 12 most common opening traps.
Because the compensation for the pawn is long-term and positional: the pressure on the a- and b-files and the active g7 bishop last all game and into the endgame. Unlike in attacking gambits, Black has no need to hurry here - the initiative does not burn out.
Benko Gambit, after the American grandmaster Pal Benko, who developed the opening in depth in the 1960s. Volga Gambit is the Russian name, from the Soviet players who analysed the ...b5 idea. They are the same opening.
There are two main routes: accept the sacrifice and defend carefully, conceding Black the initiative for the pawn, or avoid opening lines at all - return the pawn with 5.b6, play 5.e3, or decline the capture altogether with 4.Nf3. Many prefer to keep the lines closed.
Yes, it is an excellent teaching gambit: it shows clearly what positional compensation for a pawn means and how to use open files. Black's plans are clear and consistent (pressure on the a- and b-files, the bishop on g7), so the opening is easy to pick up.
