Modern Defense: Averbakh 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 Modern Defense: Averbakh System

Play White's moves of the line from memory — 1. d4 g6 2. c4 Bg7 3. Nc3 d6 4. e4 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 2 named lines that continue it, such as Modern Defense: Kotov Variation, Modern Defense: Randspringer Variation.

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