Benoni Defense: King's Indian System 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 Benoni Defense: King's Indian System

Play Black's moves of the line from memory — 1. d4 Nf6 2. c4 c5 3. d5 e5 4. Nc3 d6 5. e4 g6 — and the trainer plays White's replies; "Play the other side" turns it around.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Benoni Defense: King's Indian System page, or pick another opening in the opening trainer.
