Philidor Defense: Philidor Countergambit 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

The Philidor Countergambit is 1.e4 e5 2.Nf3 d6 3.d4 f5, the most aggressive approach for Black in the Philidor Defense and Philidor's own original recommendation. Play Black's moves of the line from memory — 1. e4 e5 2. Nf3 d6 3. d4 f5 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 4 named lines that continue it, such as Philidor Defense: Philidor Countergambit, Zukertort Variation, Philidor Defense: Philidor Countergambit, del Rio Attack, Philidor Defense: Philidor Countergambit, Berger Variation, Philidor Defense: Lopez Countergambit, Jaenisch Variation.
