Sicilian Defense · B40
Marshall Counterattack
1. e4 c5 2. Nf3 e6 3. d4 d5
The pawns on d5 and e4 stand in direct tension - the first player to resolve it chooses the structure.
The first 4 moves, explained
- 1. e4 Stakes a claim in the centre, controlling d5, and frees the bishop and queen.
- 1... c5 Fights for d4 from the flank - contesting the centre without committing a centre pawn. Theory calls this the Sicilian Defense.
- 2. Nf3 Develops the knight to f3, eyeing d4 and e5.
- 2... e6 Supports the centre, adding control of d5. Theory calls this the French Variation.
