Strategic Ideas for White
- Queenside fianchetto: Bb2 controls the long diagonal effectively
- Flexible development: Adapt to Black's setup without early commitments
- Hypermodern control: Control center from the flanks with piece pressure
- Original positions: Create unfamiliar positions for practical advantage
- Development tempo: Complete development while maintaining flexibility
- Central challenge: Challenge Black's central pawns when timing is right
Black's Main Responses
Classical Development
Black develops naturally while preparing to complete development harmoniously.
Central Occupation
Black immediately challenges the center with active piece development.
Fianchetto Response
Black mirrors the fianchetto approach with symmetrical development.
System Philosophy
This transposition combines the flexibility of the Réti with the hypermodern ideas of the Nimzo-Larsen Attack. The early b3 and Bb2 create immediate pressure on the long diagonal while maintaining maximum positional flexibility. This approach often leads to original positions where understanding matters more than memorization.
Key Strategic Themes

- Long diagonal pressure: Bb2 creates lasting influence on Black's position
- Flexible pawn structure: Avoid early pawn commitments to maintain options

For Black
