Mastering the Anti-Nimzo-Indian: c6 with 4.Bf4
If you play 1.d4 and enjoy steering games away from heavily booked theory, the Anti-Nimzo-Indian with 4.Bf4 is a fine weapon. You've just developed your bishop outside the pawn chain, eyeing the queenside and keeping flexible options. Black now faces the decision of how to challenge the centre — and the statistics show you are off to a promising start. After 1.d4 Nf6 2.c4 e6 3.Nf3 c6 4.Bf4, Black has several reasonable replies, but none of them equalises. Let's look at what White is fighting for and how to handle Black's most popular answers.

This position is all about central control with a hint of prophylaxis. By playing 4.Bf4 instead of the more common Nc3 (which invites the Nimzo-Indian proper), you keep the c3-square open for a later pawn push or piece, and you avoid early ...Bb4 pins. Your bishop sits actively on f4, pressuring the d6- and c7-squares. Black's ...c6 suggests they want to play ...d5 and challenge your centre from the queenside, but you have already prevented ...d5 from being a free equaliser. The engine rates this +0.42, a small plus for White, meaning you are slightly better. Not a knockout punch — but a clear edge to nurse into the middlegame.
The Critical Reply: 4...d5
Black's most common move by far is 4...d5, seen in 3,971 games — nearly half of all games from this position. White scores a solid 54.5% against it. The engine recommends answering with 5.e3, supporting your centre and preparing to develop your dark-squared bishop to either g3 or d6 after Black plays ...Bd6. A typical continuation runs 5.e3 Bd6 6.Bg5, when you trade bishops on your terms and maintain central tension. Notice how your early Bf4 provokes Black into revealing their dark-squared bishop's placement. Don't rush to capture on d5; keep the tension and develop first.
Black's Other Options
Beyond 4...d5, Black has several alternatives, and White scores well against all of them: - 4...Bb4+ (1,108 games, White scores 56.1%): This check is natural but not troublesome. Simply block with 5.Nbd2 (developing) or 5.Bd2. If Black trades on d2, you recapture with the knight and keep a harmonious setup. - 4...Be7 (731 games, White scores 53.1%): A quiet developing move. Continue with 5.e3 and 6.Nc3 or 6.Be2, building a classical centre. - 4...d6 (562 games, White scores 55.3%): Black prepares ...e5, but you can meet that with 5.e3 and maintain the tension. - 4...Qb6 (529 games, White scores 55.0%) and 4...Qa5+ (460 games, White scores 52.8%): Black tries to pressure b2 or check from a5. In both cases, calm development — 5.Qc1 or 5.Nbd2 — keeps your edge. The engine's preferred answer to 4...Qa5+ is 5.Nbd2, covering the important squares.
