French Advance: f6 – Your Guide to a Winning Advantage

The whole point of the French Defence is for Black to challenge your centre with ...c5 and ...d5. By playing 3...f6, Black tries a more radical approach: they want to blast open the f-file and attack your pawn on e5 directly. If you let them trade on e5, the centre gets cleared and their problems disappear. But you don't have to cooperate. The move 4.Bd3 (the engine's top choice and the one you'll see in this drill) does two things at once: it develops your king's bishop to an active diagonal, and it makes f6 ...fxe5 impossible to play without dropping the e-pawn? No — actually, 4.Bd3 doesn't directly prevent the capture, but it prepares a powerful reply. This is the critical moment: Black has several options, and only one of them keeps the game even remotely close.

The most common move here is fxe5, played over 12,600 times — that's nearly half of all games at this position. The stats say White scores 67.5% against it, making it the best possible news for you. Stockfish calls fxe5 an inaccuracy that loses about 0.8 pawns of advantage. Why? Because after 4...fxe5, White recaptures with the bishop: 5.Bxh7!, winning a pawn outright while Black's king is stuck in the centre. The rook on h8 is also threatened. Black gets zero compensation. If your opponent grabs on e5, you punish them immediately. The engine's preferred move is g6, blocking the check and protecting h7 — but that comes with its own problems, which we'll look at next.

The sharpest continuation according to the engine runs 4.Bd3 g6 5.h4 c5 6.h5. Black's idea with ...g6 is to fianchetto on g7 and stop Bxh7 tricks. Your plan is brutally direct: push the h-pawn to open lines against their king. After 5.h4, Black's kingside already looks airy. The follow-up 6.h5 forces them to either let you open the h-file or play ...h6, which leaves the g6-square weak. This is exactly the kind of position where the French Advance shines — you have space, attacking chances, and a lead in development. Even though only 848 games saw ...g6 in the database, White still scores 56.8%, which is a solid result given that this is Black's best attempt to hold things together.

If Black avoids the immediate mistake of fxe5, they'll most often try one of these moves: c5 (4,565 games, White scores 62.3%), Nc6 (4,448 games, White scores 62.7%), f5 (1,502 games, White scores 59.3%), or Ne7 (489 games, White scores 61.8%). All of these are fine for White — you score above 59% against every single one. The common thread: Black has weakened their kingside and lagged in development, and your space advantage on the kingside gives you clear attacking prospects regardless of which move they choose. The engine evaluation of +1.15 tells you that no matter what Black does from here, you are the one pressing. Just remember the key rule: if they ever play ...fxe5, snap off the h7-pawn with Bxh7.
