Ruy Lopez: Classical Variation with Nxe5 – Playing Black

ECO C64 1,566 games Stockfish +0.95

If you play 1.e4 e5, you've probably faced the Ruy Lopez and wondered what to do when White grabs the e5-pawn with 4.Nxe5. The immediate reply 4...Qh4 attacks the knight and threatens checkmate on f2 — Black is already setting traps. The engine rates this position +0.95, a clear edge for White, meaning White is objectively better here. But the statistics tell a different story: across 1,566 games, Black actually wins 55.7% of the time. White's advantage is hard to convert at club level, and one wrong move from White can be catastrophic. Let's see how Black fights for the full point.

What Black Gets Right Away

After 4.Nxe5 Qh4, Black attacks both the knight on e5 and threatens Qxf2#. White's king is suddenly exposed, and Black's dark-squared bishop on c5 eyes the g1-a7 diagonal. Even though Stockfish prefers White, the practical pressure is real. Black's queen and bishop coordinate beautifully against the kingside, and White has to be precise from move 5. The engine's best response is 5.O-O, castling into safety and threatening the Black queen with the rook. After 5...Nxe5 the game continues 6.d4 c6 — Black gives back the knight but keeps the initiative. If White handles the position casually, Black's counterplay arrives fast.

Where White Goes Wrong

The most common mistake in this position is 5.Qf3, which has been played 169 times but loses roughly 4.2 pawns according to the engine. It's a blunder because it blocks the f-pawn and fails to address the threats. White's queen looks active but is vulnerable. Also losing are 5.Nd3 (a mistake costing about 1.6 pawns) and 5.d4 (a mistake costing about 2.4 pawns). The statistics back this up: White scores only 30.2% after 5.Qf3, 32.3% after 5.d4, and 43.2% after 5.Nd3. Compare that to the 54.5% score White gets after the correct 5.O-O — and you can see why this opening is a goldmine for Black at lower and intermediate levels.

The Critical Moment: Black Against 5.O-O

When White finds 5.O-O, the position requires care. Black's best reply is 5...Nxe5, after which White plays 6.d4 c6. Black prepares ...d5 to open the centre and challenge White's bishop on b5. Black's queen is temporarily misplaced but can retreat to safety. The resulting structure gives Black solid play and chances to outplay White in the middlegame. Remember: even in this main line, White's winning percentage is only 54.5% — barely better than half. Black has every reason to be confident.

A Surprising Statistic for Black Players

Despite the engine giving White a +0.95 advantage, Black actually wins more games than White in this position: 55.7% versus 41.4%, with only 2.8% draws. That's a massive swing. It means the position is much harder for White to handle in practice than the computer suggests. Black's threats are concrete and dangerous, while White's advantage requires precise, patient play to realise. If you know the key ideas and wait for White to slip — which happens often — you'll end up with excellent winning chances.
