At first glance, the engine's +0.44 evaluation might make you think Black is already in trouble. That small edge for White is real, but it's far from decisive. In fact, across over a million games, Black wins 48.4% of the time, compared to White's 47.8% — and draws are rare at just 3.9%. Those numbers mean that in practical play, this position is an even fight. White has a theoretical plus, but Black's position is solid and the game is wide open. Your task is to complete development, maintain coordination, and look for chances to counterattack. The engine's top move is Nxd4, but whatever White plays, you have clear, principled answers.
The Engine's Top Choice: Meet Nxd4 with Nf6
The strongest continuation for White is 5.Nxd4, leading to Nxd4 Nf6 Nc3 O-O. This is also the most-played line, appearing in over half a million games. White's plan is straightforward: centralise the knight, develop the queen's knight to c3, and castle. Your plan is just as natural. After 5...Nf6, you develop a piece and attack White's e4 pawn. White will likely play 6.Nc3 to defend it, and you castle (6...O-O). Both sides have finished developing their kingside pieces, and the position remains balanced. There's no need to memorise sharp theory here — just develop sensibly, keep your pawn structure intact, and the game will offer you plenty of play.
What the Statistics Reveal About White's Choices
White has several options at move 5, and the statistics reveal which ones you should welcome and which require more care. 5.Nxd4 (the best move) gives White a modest 46.7% score — so even in the main line, you're outscoring the opponent. 5.Qxd4 is the second most popular, with White scoring 48.7% — also a great result for you. The real trouble for White comes from three suboptimal moves: 5.c3 (White scores 50.1%, but the engine considers it an inaccuracy, losing about half a pawn); 5.e5 (White scores 54.9% — a mistake costing ~1.2 pawns); and worst of all, 5.Bxf7+ (White scores only 42.4% and it's a blunder losing ~3.3 pawns). If White plays c3, e5, or Bxf7+, you're the one who should be smiling.
Punishing White's Mistakes: What to Watch For
The three known mistakes in this position are worth knowing because they give you clear winning chances. If White plays 5.c3, it's an inaccuracy — you should continue developing naturally, with ...Nf6 or ...Nc6, and you'll enjoy a comfortable position. If White plays 5.e5, that's a real mistake. The pawn push weakens White's centre and opens lines. You can respond with ...dxe5 or ...Nf6, and your extra pawn (or superior structure) will give you a clear edge. The biggest gift is 5.Bxf7+ — a blunder that loses almost 3.5 pawns' worth of advantage. Don't panic! Just take with the king (Kxf7), and White has traded a bishop for nothing but a pawn and a check. Your king is safe enough, and you're winning. Keep calm, develop, and cash in.

Frequently asked questions
Is the Philidor Defense a good opening for beginners?

The statistics at this exact position show Black wins 48.4% of games, so you're not at a disadvantage. You can focus on learning general chess principles rather than memorising long forced lines.
Should I play ...Nf6 or ...Nc6 after 5.Nxd4?
The engine's top line after 5.Nxd4 is 5...Nf6, attacking White's e4 pawn and forcing 6.Nc3 to defend it. This is the most principled move and the one played in the main continuation. While ...Nc6 is also possible, ...Nf6 is the most straightforward way to develop and challenge White's centre. Stick with ...Nf6 in this position.
What is White's worst move in this position?
The worst move by far is 5.Bxf7+, which is a blunder costing White about 3.3 pawns. White sacrifices a bishop for a pawn and a check. You should calmly capture with the king (Kxf7), and you're winning. White scores only 42.4% after this move, and that low number is mostly because weaker players still find ways to lose — don't be one of them.
Why does Black win more often than White if the engine says +0.44?

Across over a million games, Black's 48.4% win rate vs White's 47.8% shows that this is a very practical choice. The position is far from losing.
