King's Indian Attack · A07

Omega-Delta Gambit

1. Nf3 d5 2. g3 e5

In the centre, Black holds d5 and e5.

The first 4 moves, explained

• 1. Nf3 Develops the knight to f3, eyeing d4 and e5. Theory calls this the Zukertort Opening.
• 1... d5 Stakes a claim in the centre, controlling e4, and frees the bishop and queen.
• 2. g3 Prepares the fianchetto: the bishop will take the long diagonal via g2. Theory calls this the King's Indian Attack.
• 2... e5 Stakes a claim in the centre, controlling d4, and frees the bishop and queen. The pawn is genuinely on offer - this is the Omega-Delta Gambit: development and initiative over material.
