Bogo-Indian Defense
Initial Moves: 1.d4 Nf6 2.c4 e6 3.Nf3 Bb4+
Strategic Summary & Main Idea
The Bogo-Indian throws in a useful ...Bb4+ check before committing the central pawns. It is solid and flexible, and often transposes into Queen's Indian or Queen's Gambit structures.
Typical Plans for White
- Meeting the check without creating unnecessary weaknesses
- Winning the bishop pair when the trade favours White
- Building the centre with Nc3, e3 and Bd3
Typical Plans for Black
- Trading on d2 to disrupt White's coordination
- Retreating the bishop and transposing into the Queen's Indian
- Attacking the centre with ...d5 or ...c5
