After 2...d5, Black challenges White's c-pawn directly and prepares to develop naturally. Your main goals here are simple: control the centre with pawns on d5 and e6, develop your kingside pieces (Nf6, Be7, O-O), and keep the position solid. White's most popular move, 3.cxd5 (played in over 760,000 games), leads to a reversed Queen's Gambit structure where Black can play ...exd5 and aim for equality with sensible development. If White plays 3.d4, the game transposes into a Queen's Gambit Declined proper — a well-known battleground where Black's solid setup is perfectly fine. Whatever White chooses, your position is resilient, and the statistics show Black scores almost as well as White.
The Most Dangerous Line: 3.d4
While 3.cxd5 is the most common move, 3.d4 is actually the engine's top choice and the one that scores best for White (52.2%). From here, the best continuation runs 3.d4 Nf6 4.Bg5 Be7. White has built a classical centre with pawns on c4 and d4, and your job is to develop steadily. This is the critical test of the Agincourt Defense. If you know how to handle this line — developing your knight to f6, pinning ...Be7 to oppose the bishop, and preparing to castle — you will neutralise White's edge. The interactive drill will let you practice this exact position until it feels automatic.
Common Mistakes and How to Punish Them
One of the best reasons to play the Agincourt Defense is that White can easily slip. The engine flags three suboptimal moves that lose a full pawn's worth of advantage (all better was d4):- 3.g3 — an inaccuracy that loses ~1.0 pawns. White's attempt to fianchetto is premature here. Develop your knight to f6 and keep pressure on the centre.- 3.Nf3 — an inaccuracy losing ~1.0 pawns. White develops but neglects the centre. Strike back with ...dxc4 or build a strong pawn chain with ...c5.- 3.d3 — a full mistake, losing ~1.1 pawns. This passive move hands you the advantage. You can immediately seize the centre with ...dxc4 or ...e5.Knowing these three moves means you can confidently punish White's most natural-looking slip-ups from the very first turn.
How to Handle the Main Replies
Let's look at White's most common choices and your best plan for each: - 3.cxd5 (the crowd favourite, 48.6% White score): Simply recapture with the e-pawn — 3...exd5. You have a symmetrical pawn structure and a clean game. Develop your knight to f6 and bishop to d6 or e7. - 3.e3 (119,000 games, 49.4% White score): A flexible move. Play 3...Nf6 and prepare to develop. White hasn't committed to d4 yet, so stay ready to meet it. - 3.d4 (103,000 games, 52.2%): As we covered, this is the critical line. 3...Nf6 followed by ...Be7 is the solid response. - 3.g3, 3.Nf3, 3.d3 (the mistakes): Pounce on these with central activity. 3...dxc4 is often good, followed by ...Nf6 and ...c5 to challenge White's centre.

Yes. After 1.c4 e6 2.Nc3 d5, Black has a solid, time-tested setup. Statistics from over a million games show Black wins 47.0% of the time, very close to White's 48.7%. The engine rates this as a small edge for White (+0.34), but at amateur level, understanding the plans and avoiding White's best move (3.d4) is enough to fight for the full point.
What is the best move for White after 1.c4 e6 2.Nc3 d5?
The engine's top choice is 3.d4, continuing 3...Nf6 4.Bg5 Be7. This scores best for White at 52.2%. However, the most popular move in practice is 3.cxd5 (played in over 760,000 games), which scores a modest 48.6% for White and gives Black comfortable equality.
What should Black do if White plays 3.g3 or 3.Nf3?
Both are inaccuracies that lose roughly a pawn's worth of advantage compared to 3.d4. Against 3.g3, develop with Nf6 and prepare to challenge the centre. Against 3.Nf3, consider capturing on c4 (dxc4) or playing ...c5 to gain space. These are positions where Black can already hope to be better.
