Bogo-Indian Defense

When White plays Nf3 instead of Nc3, Black checks with ...Bb4+ to develop with tempo and reach a solid, flexible position. It is a low-theory, reliable companion to the Nimzo-Indian for players who value soundness.

• Check with ...Bb4+ to develop actively and gain time
• Trade or retreat the bishop and aim for a solid structure
• Play for the ...d5 or ...d6 and ...e5 setups
• Keep the game strategic and low-risk with easy development
