Bogo-Indian Defense trainer

Back to the opening, all openings to practise or my repertoire

Type a move and press Enter: e4, Nf3, O-O, or from and to squares like g1f3 (e7e8q to promote). The board is also played with the mouse.

Practise the Bogo-Indian Defense

The Bogo-Indian Defense, 1.d4 Nf6 2.c4 e6 3.Nf3 Bb4+, is a check that Black can give after White's 3.Nf3, a move often played to avoid the Nimzo-Indian Defense (3.Nc3 Bb4). Play Black's moves of the line from memory — 1. d4 Nf6 2. c4 e6 3. Nf3 Bb4+ — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 12 named lines that continue it, such as Bogo-Indian Defense: Grünfeld Variation, Bogo-Indian Defense: Exchange Variation, Bogo-Indian Defense: Nimzowitsch Variation, Bogo-Indian Defense: Wade-Smyslov Variation, Bogo-Indian Defense: Retreat Variation, Bogo-Indian Defense: Vitolins Variation, Queen's Indian Defense: Yates Variation, Queen's Indian Defense, with e3, Bb4+ Line.
