French Defense: Marshall Gambit with exd5 – A Guide for Black
Welcome to the French Defense: Marshall Gambit after 1.e4 e6 2.d4 d5 3.Nc3 c5 4.exd5 exd5. At first glance, the position looks symmetrical and solid — but the engine gives White a clear advantage of +1.29. That may sound discouraging, but don't worry: White's path to that edge is very narrow, and your opponents at club level routinely stumble. You'll face dxc5 most often (384,389 games in the database), but White's most dangerous weapon is the tricky check Bb5+. In this lesson, you'll learn what White is trying to do, where they go wrong, and how to steer the game toward your best chances. Scroll down for the interactive drill — play the position against a training engine and see if you can punish White's mistakes.

White's best move in this exact position, according to Stockfish, is Bb5+. The engine's suggested follow-up is Bb5+ Nc6 dxc5 d4. White pins your knight on c6 while opening the centre with dxc5, and your d-pawn can advance to d4 to disrupt White's centre. This line scores a staggering 57.3% for White across 91,804 games in the database. Even though you're playing Black and the engine favours White, knowing this line is essential: if your opponent plays something else, they have probably given you an edge.
The Most Common Move: dxc5 and What It Means for You
By far the most popular move in the database is dxc5, appearing in 384,389 games with White scoring 56.9%. White grabs the pawn and dares you to prove compensation. The engine's best response (following Bb5+) involves pinning your knight with the check first — but if your opponent just plays dxc5 without the check, the position changes. Your plan typically involves rapid development and pressure on White's centre: put your bishop on e6 or f5, castle kingside, and target the d4-square. The statistics show you have a 40.4% overall win rate as Black — not great, but far from hopeless. White still has to play accurately.
Three Moves That Are Bad News for White
The FACTS list three common moves that drop significant advantage for White. If you see any of these, you can be confident you're doing well: - Nf3 is an inaccuracy, losing about 0.9 pawns of advantage. Better was Bb5+. The knight develops but doesn't challenge your setup directly. - Be3 is also an inaccuracy, also losing roughly 0.9 pawns. Better was Bb5+. This natural developing move lets you seize the initiative. - Qe2+ is a full mistake, costing White about 1.1 pawns. Better was Bb5+. The check accomplishes little — you can block with Nc6 and continue developing. Recognising these moves as suboptimal gives you confidence: your opponent is already off the engine's path.
Your Typical Plans and Piece Placement
In this Marshall Gambit line, your main goals as Black are straightforward: develop quickly, complete your kingside castling, and put pressure on the d4-pawn or the c5-pawn depending on which capture White made. If White played dxc5, you aim to recapture with your bishop or knight and centralise your pieces. If White played Bb5+ first (the best line), your knight on c6 is pinned, so you need to resolve that — the engine's suggested reply is Nc6, blocking the check, after which you push d4 to strike back in the centre. The key is staying active and not allowing White to consolidate their extra space or pawn.
