Petrov's Defense · C43

Modern Attack, Murrey Variation

1. e4 e5 2. Nf3 Nf6 3. d4 Nxe4 4. Bd3 Nc6

The structure hands White the half-open e-file - rook pressure down it is a standing plan. Black mirrors with ...Nf6 and meets attack with symmetry: sound, drawish by reputation, and quietly venomous when White overpresses.

The first 4 moves, explained

• 1. e4 Stakes a claim in the centre, controlling d5, and frees the bishop and queen.
• 1... e5 Stakes a claim in the centre, controlling d4, and frees the bishop and queen.
• 2. Nf3 Develops the knight to f3, eyeing d4 and e5.
• 2... Nf6 Develops the knight to f6, eyeing d5 and e4. Theory calls this the Petrov's Defense.
