In the exact position after 1.d4 Nf6 2.Nf3 d6 3.c4, more than one million games have been played on Lichess. White wins 49.4% of them, Black wins 46.3%, and draws are rare at 4.2%. That's a healthy practical score, but the engine's evaluation is even more encouraging: Stockfish rates this +0.54, a clear edge for White. That means you are slightly better already. Black has no immediate threat and must decide how to develop. Your task is to understand which replies are hardest to face and which ones you can punish.
Black's Most Popular Reply: g6
By far Black's most frequent choice is 3...g6, appearing in 562,642 games — over half of all games from this position. Black prepares to fianchetto the bishop on g7, a solid and flexible plan. White scores 47.8% against this move, slightly below the overall average, so Black is doing something right. The engine's best line continues 4.Nc3 Bg7 5.e4, seizing a big centre. You have a space advantage and should aim for a gradual kingside or central build-up. Don't rush — Black's king will be safe after castling, but your central pawns give you lasting pressure.
The Moves That Give You More
Not every Black reply is equally challenging. Against 3...e6 (44,382 games) White scores 52.9%, and against 3...Nc6 (31,217 games) White scores 54.0% — your best results in the main replies. Black playing 3...c6 (96,465 games) gives you exactly 50.0%, while 3...Bg4 (80,846 games) is tricky at 51.1% for White, with the bishop pinning your knight. The rarest of the top replies, 3...Nbd7 (89,065 games), is actually Black's worst statistically at 47.4% for White. Remember: none of these options change the overall verdict — the position always favours you slightly if you play accurately.
A Typical Plan for White
After 3.c4 you have a classical pawn centre with pawns on d4 and c4 and a knight on f3. Your next moves should aim for quick development and king safety. If Black plays 3...g6, follow the engine's suggestion with Nc3 and e4, building a big centre. If Black plays 3...Bg4, consider h3 to ask the bishop what it intends. Against 3...c6 or 3...e6, Black is preparing ...d5 to challenge your centre — you can meet that by developing naturally and only releasing the tension when it benefits you. The key idea: play simple developing moves, don't weaken your pawn structure unnecessarily, and trust that your space advantage will tell in the middlegame.
