Sicilian Defense · B20

Euwe Attack, Prins Gambit

1. e4 c5 2. b3 d5 3. Bb2

The pawns on d5 and e4 stand in direct tension - the first player to resolve it chooses the structure. White's queenside bishop takes the long diagonal.

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. b3 Prepares the fianchetto: the bishop will take the long diagonal via b2. Theory calls this the Czerniak Attack.
• 2... d5 Stakes a claim in the centre, controlling e4, and frees the bishop and queen.
