Averbakh Variation
Named variation
A pin that arrives before the piece it needs is even developed
After 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Be2 O-O, most King's Indian lines continue with White developing the king's knight to f3 before anything else. The Averbakh Variation does something different: 6.Bg5, pinning Black's f6 knight before Nf3 has even been played. Because the knight normally defending against a quick central break isn't fully supported the way it would be in the Classical Variation, this early pin is designed to make Black's most natural plan — striking with ...e5 — genuinely harder to execute cleanly, or at least more committal than usual.
What the pin actually threatens to disrupt
If Black plays the natural ...e5 immediately, White has 7.dxe5, and after 7...dxe5 8.Qxd8 Rxd8, the position simplifies into an endgame where the pin on f6 becomes an actual, uncomfortable asset for White rather than a minor inconvenience, since Black's bishop or pawn structure has to account for it while some tension around the c6 knight's development remains. Black's more common response is instead ...c5 or ...Na6, delaying the central break and reorganizing pieces first — the point being that the Averbakh's pin removes ...e5 as a completely free, automatic reply and forces Black to actually calculate whether striking the center right away is favorable.
Starting position. Averbakh Variation — the bishop pins the knight before it develops.
The pin that arrives before Nf3: White discourages the King's Indian's usual central break before it's even attempted.
Why this differs from the Classical Variation's approach
The Classical Variation, by contrast, develops Nf3 first and lets Black play ...e5 freely, leading straight into the Mar del Plata race described on its own page. The Averbakh's whole reason for existing is to sidestep that specific structure — by pinning the knight before committing Nf3, White keeps the option of meeting ...e5 with a favorable trade into an endgame rather than accepting the opposite-wing attacking race the Classical Variation embraces. A player choosing the Averbakh is explicitly choosing to avoid the Mar del Plata's sharp, symmetric complications in favor of a structure where White holds a small, persistent initiative instead.
Sidestepping a race rather than out-calculating it
The Averbakh Variation, named for Soviet grandmaster Yuri Averbakh, appeals to White players who respect the King's Indian's attacking potential in the Classical lines and would rather avoid it structurally than out-calculate it move by move. It demands real understanding of when ...e5 is actually favorable to allow versus when it should be met with the endgame-simplifying trade, which makes it a strategically demanding choice rather than a purely tactical weapon — but it rewards a player who prefers steering the game away from a race entirely.
Black's other main answer: striking with ...c5 instead
Rather than reorganizing slowly, some Black players meet the Averbakh with an immediate ...c5, striking at White's center from the queenside instead of contesting it with ...e5 at all. This sidesteps the specific endgame the pin makes favorable and heads toward a structure that has more in common with a Benoni-style fight than with typical King's Indian middlegames — a genuinely different practical decision than either playing into the trade line or slowly maneuvering, and one that requires White to know Benoni-adjacent plans alongside standard King's Indian theory to meet it well.
Playing ...e5 as though the pin isn't there
The single most common Black error is autopilot: playing ...e5 out of habit, the way it would be played against the ordinary Classical Variation, without recognizing that the pin changes the evaluation of the resulting trade into an endgame slightly in White's favor. White has a matching autopilot failure — allowing ...e5 without any real follow-up plan, missing the specific point of the favorable trade the whole pin was designed to enable in the first place.
The whole point in one sentence
The Averbakh isn't trying to win material or attack directly — it's trying to make Black's single most automatic King's Indian move, ...e5, into a real decision rather than a free reply.

Frequently Asked Questions
Does the Averbakh Variation actually stop Black from playing ...e5?
No — ...e5 is still legal and playable, but the pin changes the evaluation of the resulting position compared to the Classical Variation, often favoring White slightly in the trade-into-endgame line, which is enough to make many Black players choose a different plan instead.
What's Black's most common way of avoiding the trade-into-endgame line?
Delaying the central break with moves like ...c5, ...Na6, or ...Nbd7 first, reorganizing pieces before deciding on ...e5, is the most common approach — it accepts a slower game in exchange for avoiding the specific structure the pin makes favorable for White.
Is the Averbakh Variation still commonly played at a high level?
It has a long, respected history and remains a legitimate weapon, though it has never displaced the Classical or Sämisch Variations as White's most common main approach — it functions more as a specific tool for players who want to avoid the Mar del Plata race specifically.
Who was Yuri Averbakh, and why does the variation carry his name?
Averbakh was a Soviet grandmaster and one of the most influential endgame theorists in chess history; the variation is credited to his analysis of using the early Bg5 pin to steer the King's Indian toward the favorable trade-into-endgame structure described above, consistent with his broader reputation for endgame-focused strategic ideas.
