After 4.dxe5, White has given up the e4 pawn and recaptured with a tempo, winning back the pawn on e5 later. Your main trumps are central space (your pawn on e5 cramps Black) and the open files that will appear once the centre clears. Black's knight on e4 is awkward: it can't stay there forever, and any move it makes costs time. The engine's top recommendation, d5, shows you the right idea — blockading Black's counterplay in the centre and preparing to develop with Nbd2, targeting the knight. You're not trying to trap the knight immediately; you're building a positional grip that leaves Black struggling for equality.
The Engine's Path: d5 as a Model
If you want to see what best play looks like, follow Stockfish's suggestion: d5, with the plan Nbd2, Nc5, and c3. That sequence restricts Black's pieces, kicks the knight away, and solidifies your centre. In the drill, when the engine plays the strongest moves against you, this is the kind of setup you'll aim for. You don't need to memorise 15 moves — just absorb the idea: push d5 early, develop your knight to d2, and force Black's knight to retreat to an awkward square. The statistics back this up: while d5 is only the second-most-popular move in practice (100,862 games), it's the engine's choice, and the most-played alternatives from Black all score well for you.
What the Numbers Reveal About Black's Replies
Looking at Black's most popular moves tells a clear story. Bc5 is the most common reply (141,565 games), but White only scores 48.2% — it's tricky, so you'll need to stay alert. The three biggest opportunities come from Black's inaccuracies: Nc6 (loses ~0.7 pawns), Qe7 (loses ~0.8 pawns), and Nc5 (loses ~0.8 pawns). Each of these is a mistake compared to the correct d5. In each case, Black misplaces a piece or wastes time, and you gain a clear advantage. The drill will show you how to capitalise on these errors — spotting them at the board is where the real gains are made.
Spotting and Punishing the Three Key Mistakes
Here's what to look for in the position after 4.dxe5. If Black plays Nc6, they develop a piece but fail to challenge your centre — you should be able to build pressure quickly. If Black plays Qe7, they block their own bishop and waste a tempo — your development lead will matter. And if Black plays Nc5, the knight goes to a nice-looking square but still doesn't solve the central problem. In all three cases, the engine says Black should have chosen d5 instead. Your job as White is to recognise these moments, keep developing with purpose, and trust that your +0.31 edge will grow into something more serious.

Frequently asked questions
Is 4.dxe5 a good move for White in the Petrov Defense?
Yes, it's perfectly sound. Stockfish rates the position +0.31 in White's favour, meaning a small but real advantage. White wins 51.1% of games from here in the Lichess database, so it's a practical choice that keeps pressure on Black without taking unnecessary risks.
What is the best move for Black after 4.dxe5 in the Petrov?
According to the engine, Black's best reply is d5. This move challenges White's centre and helps Black complete development. Unfortunately for Black, many players choose other moves — Nc6, Qe7, or Nc5 — which are all inaccuracies that give White a larger advantage.
Why is Nc6 a mistake for Black in this Petrov line?
Nc6 is classified as an inaccuracy because it loses roughly 0.7 pawns of advantage compared to the better move d5. Black develops a piece but fails to address the central tension, allowing White to maintain a comfortable edge with straightforward play.
What should White do against Black's most common reply Bc5?
Bc5 is played in over 141,000 games and is the most popular Black response. White scores only 48.2% here, so it's the trickiest line to face. The engine recommends continuing with d5 and Nbd2, just as in the main line — stay principled, don't panic, and you'll gradually untangle your advantage.
