Benoni Defense: King's Pawn Line, with Bg5 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 Pawn Line, with Bg5

Play White's moves of the line from memory — 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f3 O-O 6. Bg5 c5 7. d5 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 4 named lines that continue it, such as King's Indian Defense: Steiner Attack.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Benoni Defense: King's Pawn Line, with Bg5 page, or pick another opening in the opening trainer.
