Grünfeld Defense: Three Knights Variation, Petrosian 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 Grünfeld Defense: Three Knights Variation, Petrosian System

The Petrosian System of the Grünfeld Defense, also called the Taimanov Variation, is 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.Bg5. Play White's moves of the line from memory — 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Nf3 Bg7 5. Bg5 — and the trainer plays Black's replies; "Play the other side" turns it around.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Grünfeld Defense: Three Knights Variation, Petrosian System page, or pick another opening in the opening trainer.
