The Big Idea Behind 4.d5

The Queen's Gambit Accepted often tempts Black into holding on to the extra pawn on c4, but you don't even need to worry about that yet. With 4.d5 you strike the centre, kick the knight from c6, and open lines for your pieces. White's main trumps are space and development: Black's knight must move again, and the d5-pawn cramps Black's position. Stockfish rates this +0.87, a clear edge for White. That means you are clearly better here. Your plan is simple: recapture the c4-pawn soon, develop naturally, and keep the pressure on Black's disorganised army.

Black's Most Popular Reply: 4...Nb4 (a Mistake)

The most common move in the database is 4...Nb4, played in 58,654 games. That's good news for you — it's actually a mistake that loses roughly 2.2 pawns of advantage. The knight looks aggressive on b4, threatening ...c2+ or ...Nxd5, but in reality it just wastes time. Your best response continues aggressively: push forward and don't let Black's threats rattle you. White scores a commanding 71.8% against 4...Nb4. The engine's preferred plan is to continue with e4, building a massive centre, then follow with ...e6 Bxc4. Once you recapture on c4, your centre is dominant and Black's misplaced knight on b4 will have to retreat again.

The Engine's First Choice: 4...Nb8

Black's safest move is the humble retreat 4...Nb8, which the engine considers the only correct reply. It's played in 49,525 games. Why is a retreat the best option? Because every other knight move lets you gain time or lose your advantage. After 4...Nb8 5.e4 e6 6.Bxc4, White has full control of the centre, leads in development, and Black's knight has wasted two moves to end up right back where it started. White still scores 64.4% from here — that's a strong result even against Black's best defence. Your task is to keep developing quickly, castle, and enjoy the spacious position.

Punish the Blunders: Na5 and Ne5

Two of Black's knight moves are outright bad news for them. 4...Na5 (26,111 games) is an inaccuracy that costs roughly 0.9 pawns — the knight goes to the edge of the board, far from the action. White scores 68.9% against it. Even worse is 4...Ne5 (1,930 games), a blunder losing about 3.2 pawns. The knight exposes itself to immediate attack; you can chase it with developing moves and White wins 80.5% of games from there. Treat both of these as gifts: develop with tempo, keep the centre strong, and you'll have a dominant position with minimal resistance.

What the Statistics Tell You

Across 141,544 games in the Lichess database, White wins this position 69.0% of the time, with only 28.2% of Black wins and 2.9% draws. Those numbers are hard to ignore — this is one of those openings where the ball is in your court from move 4. Black's most common choices are all sub-optimal, and even the best reply (4...Nb8) still gives you a comfortable advantage. The key takeaway: trust the statistics, learn the simple follow-ups, and you'll convert this early edge into wins far more often than not.
