Bogo-Indian Defense: Retreat Variation 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: Retreat Variation

Play White's moves of the line from memory — 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. g3 Bb4+ 5. Bd2 Be7 6. Bg2 O-O 7. O-O c6 8. Qc2 Nbd7 9. Bf4 b6 10. Nbd2 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 1 named line that continue it.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Bogo-Indian Defense: Retreat Variation page, or pick another opening in the opening trainer.
