Réti Opening · A09

Reversed Blumenfeld Gambit

1. Nf3 d5 2. c4 d4 3. e3 c5 4. b4

Nf3 and c4 attack d5 with pieces and the flank pawn while the centre pawns wait - hypermodern control now, central strikes later.

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. c4 Challenges the pawn on d5 - the central tension has to resolve. Theory calls this the Réti Opening.
• 2... d4 Pushes on to d4 - grabbing space and fixing the centre, and the queen breathes. Theory calls this the Advance Variation.
