Nimzo-Indian Defense · E34

Classical Variation, Belyavsky Gambit

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Qc2 d5 5. cxd5 Qxd5 6. Nf3 Qf5 7. Qd1 e5

An early pawn trade leaves the c-file as White's avenue and the d-file as Black's - both sides get real winning chances down their own file. ...Bb4 pins the knight that supports e4: Black fights for the light squares, often trades on c3 to damage the pawns, and plays structure against the bishop pair. White's knight on c3 is pinned against the king.

The first 4 moves, explained

• 1. d4 Stakes a claim in the centre, controlling e5, and frees the bishop and queen.
• 1... Nf6 Develops the knight to f6, eyeing d5 and e4.
• 2. c4 Fights for d5 from the flank - contesting the centre without committing a centre pawn.
• 2... e6 Supports the centre, adding control of d5.
