Queen's Pawn Game: Modern Defense after 2.c4 Nf6

Your setup with ...g6 and ...Nf6 targets the dark squares and prepares to fianchetto the king's bishop. Unlike some Hypermodern defences, you're not inviting White to build a huge centre — you're getting ready to challenge it. The engine evaluates the position at +0.40, a slight advantage for White, but the practical results tell a different story. Black's winning percentage (48.1%) actually outpaces White's (47.7%), with very few draws (4.1%). That means this is a fighting opening where Black's solid structure and active piece play create real winning chances. Your main idea after White's reply is to strike in the centre with ...d5, transposing into a Queen's Gambit Declined-style structure where your dark-squared bishop will be a powerful piece.

Stockfish recommends Nc3, and it's easy to see why. After 2.c4 Nf6, White wants to develop and maintain control of d5. The most-played continuation in the database is 3.Nc3 d5 4.cxd5 Nxd5, leading to a familiar Scandinavian-like structure where Black has a knight on d5 and a fianchettoed king's bishop in the making. Over 8.3 million games have reached the position after Nc3 (by far the most popular reply), and White scores 48.3% — still below Black's individual win rate. Your plan is straightforward: meet Nc3 with ...d5 immediately. If White captures on d5, recapture with the knight and prepare ...Bg7 and ...0-0. You'll have active piece play and no clear weaknesses.

Not every opponent will play Nc3. Here are the other frequent tries and what you should know about each one, based on statistics from millions of games: - 3.Nf3 (1.38 million games, White scores 47.1%): A quieter development. White keeps options open but delays challenging the centre. You can still play ...d5 or continue your fianchetto with ...Bg7 and ...0-0. Black scores well here. - 3.e3 (626k games, White scores 44.7%): White's worst score by a clear margin. This passive move doesn't contest the centre strongly. Play ...d5 or ...Bg7, and you'll likely equalise comfortably or get a slight edge. - 3.g3 (182k games, White scores 49.4%): White fianchettoes too, aiming for a symmetrical setup. Black's winning percentage here is the lowest among White's options, but the position remains perfectly playable. - 3.Bf4 (167k games, White scores 45.3%): A provocative move that leaves the d4-pawn undefended. Black can consider ...d5 or ...c5 immediately to challenge the centre.

A golden nugget from the statistics: 3.Bg5 is actually an inaccuracy, losing roughly 0.7 pawns of advantage for White. The engine says Nc3 was better instead. Many club players try Bg5, pinning your knight and hoping to disrupt your development, but the numbers show White scores only 46.0% from 419k games — well below their average. After 3.Bg5, you can immediately strike with ...d5 or ...c5, exploiting the fact that White's bishop is slightly misplaced on g5. If White captures on f6 later, you can recapture with the g-pawn, opening the g-file for your rook and keeping your centre intact. This is a concrete way to seize the initiative when White reaches for a move that looks natural but isn't best.
