Scandinavian Modern: c4 — How to Play the 3...c6 Line as Black

After 1.e4 d5 2.exd5 Nf6 3.c4 c6, you have set a trap of sorts. White's d5-pawn is attacked — if they capture on c6 immediately with dxc6, you recapture with the knight, developing with tempo and leaving White's c4-pawn a target. This is why dxc6 is by far the most common move (1,146,498 games), yet White scores only 42.8% with it — meaning you, as Black, score over 57% against it. That is a massive practical success rate for a supposedly inferior position. White also has respectable alternatives like Nc3 (the engine's choice) and d4, each leading to different pawn structures. What all these lines have in common is that you play the Scandinavian with active piece play and genuine winning chances, not just survival.

Stockfish recommends that White play Nc3, continuing with Nc3 cxd5 d4 Nc6. This line keeps the c4-pawn alive and builds a solid centre. From the engine's viewpoint, White enjoys a tiny +0.26 advantage — that means you are very slightly worse, but the margin is negligible for human play. In practice, this position leads to a complex middlegame where you have easy development, central control, and a sound pawn structure. The database confirms this: in the 301,257 games where Nc3 was played, White scored 46.0%, meaning you still win more often than White despite the engine's cold verdict. Your plan is straightforward: recapture on d5, develop the b8-knight to c6, and prepare to challenge the centre with ...e6, depending on White's setup.

One White move to welcome is d3 — and it is played in 11,455 games, so it happens. According to the engine, d3 is an inaccuracy that loses roughly 0.8 pawns of advantage compared to Nc3. White scores only 40.6% with d3, which is your best result against any of the common replies. Why is d3 so poor? It defends the c4-pawn but does nothing to contest the centre or develop actively. After you capture on d5 (cxd5), White's pawn on d3 looks passive compared to the more natural d4. You can follow up with ...Nc6, enjoying easy development while White struggles to find a good square for their pieces. If your opponent plays d3, seize the chance to play actively and punish their slow setup.

Let's look at the full picture from the Lichess database. Here is how White's five most popular moves score from this position (higher = better for White, so lower = better for you):- dxc6: White scores 42.8% (played 1,146,498 times) — an excellent result for you.- Nc3: White scores 46.0% (301,257 games) — the engine's pick, but you still win more often.- d4: White scores 52.6% (40,509 games) — the only move where White edges ahead statistically.- Qa4: White scores 41.1% (32,074 games) — another very good outcome for Black.- Nf3: White scores 47.6% (24,685 games) — balanced but slightly favourable to you.- d3: White scores 40.6% (11,455 games) — the worst result for White of all.The pattern is clear: this position rewards Black in practical play. Even against the best engine move (Nc3), Black scores 54% — a fantastic hit rate for a position that theory considers only marginally better for White.

When White plays the most popular move — dxc6 (1,146,498 games) — your response is simple and strong: recapture with the knight. You develop a piece, attack the c4-pawn, and leave White with a somewhat awkward position. The c4-pawn is now a target. White may try to defend it with Nc3 or b3, but you have easy development and your king can castle quickly. The statistics back this up: White scores only 42.8% after dxc6, meaning you win more than 57% of the time from this line. The key is not to rush — just develop naturally, keep the pressure on c4, and wait for White to commit to a plan. Your position has no weaknesses, and White's isolated c4-pawn is already under fire.
