When you play 3...c5, you mirror White's pawn on d4 with your own on c5, creating tension in the centre. The central question is whether White captures (dxc5) or supports the d4-pawn (c3, e3) or develops to g2 first. Because Black has equal space and easy development, this position is extremely balanced — the engine gives +0.07, meaning no edge for either side. Your plan is straightforward: develop naturally, control the centre, and be ready to recapture on c5 or meet White's fianchettoed bishop. The bishop on g2 will eye your queenside, so timely moves like ...Nc6 and ...e6 (or ...g6) are common.
The Engine's Best Move: Bg2
Stockfish's top choice is 4.Bg2, continuing the fianchetto. After that, the main line runs 4.Bg2 cxd4 5.O-O h6 (preventing Bg5). This sequence has been played tens of thousands of times. Notice that you capture on d4 immediately — you don't wait around. The pawn trade opens the centre slightly, and White castles while you play a useful prophylactic move with ...h6, stopping a bishop pin on your knight. From here the game is balanced, and both sides have straightforward development: your queen recaptures on d4 or ...e6 followed by ...Nc6. The engine's continuation is the benchmark for sound play, but White doesn't always find it.
White's Most Popular Replies — and Your Edge
Over 119,000 games from this position show clear patterns. 4.Bg2 is by far the most common (70,295 games) and White scores 49.1% — essentially even. But watch what happens when White plays other moves: 4.c3 (20,437 games) drops White's score to 46.8%; 4.dxc5 (14,469 games) gives White just 43.5%; 4.e3 (5,492 games) scores 45.3%; and 4.c4 (5,408 games) scores 48.2%. The best White can do is the engine move Bg2. If White plays anything else, your winning chances actually improve. The reason: deviating from the symmetrical fianchetto allows you to seize the centre or win the pawn back favourably.
The One Mistake You Can Punish
The FACTS list one clear inaccuracy: 4.Bg5 is a mistake that loses roughly 0.8 pawns of advantage (the engine says Bg2 was better instead). If White pins your knight with 4.Bg5, they're wasting time — you can chase the bishop with ...h6, and if it retreats to h4, ...g5 forces it to a bad square. Black scores 57.9% from the Bg5 line (White wins just 42.1% across 667 games). When you face 4.Bg5, don't panic — your position is already better. Play ...h6 immediately and enjoy being the one with the edge.
