Sicilian Defense: Najdorf Variation, Amsterdam 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 Sicilian Defense: Najdorf Variation, Amsterdam Variation

The Amsterdam Variation is 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.f4, one of the many sixth moves against the Najdorf. Play White's moves of the line from memory — 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. f4 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 1 named line that continue it, such as Sicilian Defense: Scheveningen Variation, Classical Variation, Paulsen Variation.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Sicilian Defense: Najdorf Variation, Amsterdam Variation page, or pick another opening in the opening trainer.
