Sicilian Defense: Kan Variation
ECO B41 · 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 a6
The Kan Variation, 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6, is one of Black's most flexible Sicilians. The move 4...a6 takes the b5 square from White's knights and prepares ...b5, while Black delays the development of the kingside pieces until White commits. Black's queen often comes to c7, the bishop can go to c5, b4, d6 or e7, and the knight to f6 or e7.
Plans for White
The main tries are 5.Bd3, guarding e4 and preparing c4 and Nc3, and 5.c4, an immediate Maroczy bind that clamps down on d5 and b5. 5.Nc3 Qc7 6.Bd3 is a third popular choice. White usually castles short, puts the queen on e2 and tries to use a space advantage before Black finishes development.
Plans for Black
Black can set up a hedgehog with pawns on a6, b6, d6 and e6 and pieces behind them, waiting for the right moment for ...b5 or ...d5. Other plans hit the d4 knight early with ...Bc5, or use ...Qc7 and ...Nf6 to pressure e4.
Typical pawn structures
Against c4 the key picture is the hedgehog against the Maroczy bind: Black has less space but no weaknesses and two pawn breaks.
Who it suits
Patient counterpunchers who like flexible setups and do not want to memorize long forced lines.
Common traps
Because Black castles late, sacrifices such as Nd5, Nxe6 or Bxb5 appear once White's pieces are developed, especially with the queen on c7. If Black never plays ...d6, a white knight that reaches d6 via e4 can paralyze the position.
