Chess Opening Trainer

Classic open game starting 1.e4 e5 2.Nf3 Nc6 3.Bc4 — fast development and quick king safety.

1.e4 e5 2.Nf3 Nc6 3.Bb5 — pressures the c6 knight defending e5; deep strategic main lines.

1.d4 d5 2.c4 — challenges the d5 pawn to fight for central control.

1.d4 followed by Nf3, Bf4, e3, c3 — a solid system you can play vs almost anything.

1.c4 — flank opening, often transposes to many structures.

1.Nf3 followed by g3, Bg2, O-O, d3, Nbd2, e4 — a flexible system for white.

1.e4 c5 — the most popular reply to e4. Asymmetrical play, fights for the center indirectly.

1.e4 e6 — solid, often leads to closed positions with chain pawns.

1.e4 c6 — solid and resilient, prepares ...d5 with a strong pawn structure.

1.d4 Nf6 2.c4 g6 — hypermodern: cede the center early, then strike back.

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 — pin the c3 knight; deeply strategic lines.

1.e4 d5 — direct challenge to the e4 pawn from move 1.
