White gives up the bishop pair to saddle Black with doubled c-pawns — a permanent structural concession. The position after 4...dxc6 (Black's best) is famously balanced: Stockfish rates it -0.16, a sliver in Black's favor. That small negative is the honest price of the trade. White isn't winning the opening; White is simplifying to an endgame where the healthy 4-3 kingside pawn majority can be converted into a passed pawn — a patient, strategic weapon.
Black's two main recaptures
- 4...dxc6 — the theoretically correct recapture taken in 6,011,628 games (79.6% of all Exchange games). Black opens the d-file and keeps the pawn center. White scores 47.3% — equal and positional.
- 4...bxc6 — popular at club level (1,529,615 games), keeps the c6 pawn closer to center but creates a different pawn structure. White scores a clear 57.1% — Black has fewer active plans without the open d-file.
The rarer tries (4...b5, 4...Nf6, 4...b6) are all significant inaccuracies or blunders in the facts file — White scores 72–84% against each.
How to play it as White
After 4...dxc6, castle kingside, play d3 and Nbd2, then slowly expand with f3 and g4 or push the queenside with b4 to challenge the c-pawn complex. The engine's principal variation continues 5.O-O Qd6 6.h3 — a quiet move that prevents Bg4 and keeps maximum flexibility before committing. Avoid early queen exchanges unless you've prepared a concrete pawn-majority plan: the Exchange works through accumulated small advantages, not tactics. Against 4...bxc6, play more actively — Black's doubled c-pawns are weaker here and your central control is stronger.
What 7.5 million games say
White scores 49.3% across 7,555,638 Lichess games — a shade below 50%, fully consistent with the -0.16 Stockfish assessment. The key split: against 4...dxc6 White scores 47.3% (the correct, equal line), but against the club-level 4...bxc6 the score jumps to 57.1%. The Exchange is not a try for advantage — it's a try for a structurally clear, theory-light game where White knows the plan and Black often doesn't.

Frequently asked questions
Is the Ruy Lopez Exchange good for beginners?
Yes — it cuts memorization to almost zero. After 4.Bxc6 the structure is fixed and White's plan (castle, build, push the kingside majority) is the same every game. The -0.16 eval is a fair trade for that clarity.
Why does Stockfish give -0.16 for White — does that mean it's a mistake?
No. -0.16 is statistically noise — less than a fifth of a pawn. Stockfish's principal variation continues with normal moves on both sides. The Exchange is objectively fine; the negative simply reflects that doubling Black's pawns doesn't yield a concrete initiative at high depth.
Should Black recapture with d×c6 or b×c6?
4...dxc6 is correct — it opens the d-file and gives Black real compensation for the pawn structure (White only scores 47.3% across 6M games). 4...bxc6 is the mistake most club players make, and White scores 57.1% against it.
What is White's winning plan in the endgame?
Convert the kingside 4-3 pawn majority into a passed pawn while Black's doubled c-pawns restrict a queenside counterpart. The technique takes patience: trade pieces, activate the king, and march the f/g/h pawns. Bobby Fischer famously used this exact plan.
