It might feel uncomfortable giving up the centre on move three, but the numbers tell a clear story. In 24,643 games from this exact position, Black wins 53.8% of the time, against only 42.6% for White, with 3.6% draws. That's a healthy plus for the second player at the club level. The engine agrees: -0.17 is as close to equal as you'll see in a sharp opening. White's bishop on g5 looks active, but it's also a target. Your task is to choose a move that keeps the pressure on, and the stats suggest one reply stands out.
The Best Reply: 3...e6
The engine's top choice is 3...e6, played in 6,585 games — the most popular move by a small margin. It prepares to recapture on c5 with the bishop, giving you quick development and a harmonious setup. After 4.a3 (to avoid ...Bb4 pins) Bxc5, you have a comfortable position with no weaknesses. White's score drops to just 38.4% when you play this way. The idea is straightforward: develop naturally, castle quickly, and enjoy your slight lead in the statistics. You're not trying to trap White — just playing solid chess with a plus.
Watch Out: The Popular but Risky Alternatives
Two other common replies come with warnings. 3...e5 (2,960 games) looks natural, pushing in the centre, but the engine calls it an inaccuracy that loses about 0.8 pawns of advantage — the better move was e6. White's score jumps to 43.8% against it, and you'll find yourself struggling to justify the pawn structure. 3...g6 (942 games) is worse still: a full mistake losing roughly 1.1 pawns, as White scores 40.7% against it. The fianchetto looks tempting, but it leaves your dark squares too weak and doesn't address the centre. If you feel tempted by either, remember that e6 is both the engine's favourite and the statistical winner.
What About 3...Qa5+?
The check 3...Qa5+ is the second most common reply (6,297 games), and it's playable but slightly less effective than e6. White scores 44.5% against it. The idea is to regain the pawn immediately, but you give White time to develop with tempo moves like Nc3 or c3. You'll often end up in a similar structure, but the queen can become a target. If you prefer this line, it's not a mistake — but the data shows e6 gives you better chances. The drill will help you compare both and see which suits your style.

Why is 3...g6 considered a mistake?
