Ruy Lopez: Exchange 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 Ruy Lopez: Exchange Variation

The Exchange Variation of the Ruy Lopez (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6) gives up the bishop to damage Black's pawn structure. Play White's moves of the line from memory — 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bxc6 — and the trainer plays Black's replies; "Play the other side" turns it around.

"Drill all" adds the 10 named lines that continue it, such as Ruy Lopez: Exchange Variation, Normal Variation, Ruy Lopez: Exchange Variation, King's Bishop Variation, Ruy Lopez: Exchange Variation, Keres Variation, Ruy Lopez: Exchange Variation, Lutikov Variation, Ruy Lopez: Exchange Variation, Gligoric Variation, Ruy Lopez: Exchange Variation, Alapin Gambit, Ruy Lopez: Exchange, Alekhine Variation, Ruy Lopez: Exchange Variation, Bronstein Variation.
