Philidor Defense: Philidor Countergambit, del Rio Attack 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 Philidor Defense: Philidor Countergambit, del Rio Attack

Play White's moves of the line from memory — 1. e4 e5 2. Nf3 d6 3. d4 f5 4. dxe5 fxe4 5. Ng5 d5 6. e6 — 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 Philidor Defense: Philidor Countergambit, Berger Variation.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Philidor Defense: Philidor Countergambit, del Rio Attack page, or pick another opening in the opening trainer.
