Playing White in the French Defense: Tarrasch Variation with c5

The French Defence is all about the tension between White's space advantage and Black's solid pawn chain. After 1.e4 e6 2.d4 d5 3.Nd2 c5, Black is saying: I'll let you occupy the centre, but I'll attack it immediately. By playing 4.Ngf3, you avoid the main line Tarrasch (4.exd5) and keep the centre fluid. Your edge, while small, comes from better development and more space — especially if Black trades on d4 too early, which can free your pieces. The key idea is to complete development before committing to a pawn break, and to punish Black if they waste time.

Black's most common move here is Nc6, appearing in 81,976 games (just under half of all encounters). White scores 51.7% from this position — solid, but not crushing. The engine's best continuation is: exd5 exd5 Bb5. This line targets Black's knight on c6, pinning it to the king and threatening to double Black's pawns on the queenside. After Bb5, you've traded your e4 pawn for Black's d5 pawn, and your bishop becomes very active. Black often responds with Qb6 or a6, but your development lead remains intact. Notice how the engine doesn't rush to capture on c5 — instead, it exchanges on d5 first to fix the pawn structure.

One move, c4, is flagged as a known inaccuracy in this position, losing roughly 0.7 pawns in evaluation. The engine says the better move was cxd4 instead. Why is c4 so bad? It allows Black to capture on d4 (cxd4) and then after Nxd4, Black's queen can come to b6, putting pressure on b2 and your knight on d4 simultaneously. You end up with a weakened pawn structure and a lag in development. The 5,974 games where c4 was played show White scoring 54.1% — which looks okay, but those games include lower-rated play where the mistake goes unpunished. Against a prepared opponent, c4 is a trap you don't want to fall into.

Across all 164,166 games from this position, White wins 52.4%, draws just 3.8%, and Black wins 43.8%. The extremely low draw rate is typical of the French — positions are sharp and mistakes get punished. The best scoring move for White is dxe4 (58.8% over 10,226 games), but that's rare because Black usually doesn't play it — it's actually Black capturing on e4, which is a mistake. Among Black's normal moves, Qb6 (52.2%) and c4 (54.1%) offer White slightly better results, while Nf6 (49.4%) is the only one where Black scores above 50%. If you see Nf6, be extra careful — Black is developing sensibly and the position requires accurate play.
