Queen's Gambit Declined: Marshall Defense 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 Queen's Gambit Declined: Marshall Defense

The Marshall Defense (1.d4 d5 2.c4 Nf6) is a rare and fairly dubious way of declining the Queen's Gambit. Play Black's moves of the line from memory — 1. d4 d5 2. c4 Nf6 — and the trainer plays White's replies; "Play the other side" turns it around.

"Drill all" adds the 1 named line that continue it, such as Queen's Gambit Declined: Marshall Defense, Tan Gambit.

Read about the line, its statistics on Lichess and Stockfish's evaluation on the Queen's Gambit Declined: Marshall Defense page, or pick another opening in the opening trainer.
