White · 1.e4 e5
Ruy Lopez
1.e4 e5 2.Nf3 Nc6 3.Bb5
The Spanish Opening: pin the knight that defends e5, and play for long-term pressure instead of a quick mate on f7.
What it is
The bishop pins or threatens the knight on c6, which is the piece holding e5. White is not grabbing a pawn on move four. White is asking Black to make a concession in the centre or on the queenside, then occupying d4 under better circumstances than in the Italian.
How to play it
- Same start as the Italian: 1.e4 e5 2.Nf3 Nc6, then 3.Bb5.
- After 3...a6, decide: take on c6 (Exchange) or retreat to a4 (almost everything else).
- Castle. Play Re1, c3, and d3 or d4. The Ruy is a system of improving pieces, not a forced win.
- Know one line against the Berlin (3...Nf6) and one against the Marshall, even if you decline the Marshall with a quiet anti-Marshall.
Main variations
Morphy Defense
3...a6
The main move. Black asks the bishop what it is doing. 4.Ba4 keeps the tension; 4.Bxc6 is the Exchange. Most of the opening’s theory lives after 4.Ba4 Nf6 5.O-O.
Berlin Defense
3...Nf6
Solid, and a different game. The famous Berlin endgame after 4.O-O Nxe4 5.d4 Nd6 6.Bxc6 dxc6 7.dxe5 Nf5 8.Qxd8+ is a queenless slog. At club level, 4.d3 keeps pieces on and is a perfectly good choice.
Marshall Attack
8...d5
Black sacs a pawn for a kingside attack in the closed Ruy. If you do not want to defend it, play an anti-Marshall (a4, or d3 systems) rather than walking in cold.
Exchange Variation
4.Bxc6
White doubles the c-pawns and plays against the structure. Do not snatch e5 next: 5.Nxe5 Qd4 wins the pawn back with interest. 5.d3 is the adult move.
Closed Ruy
9.h3
The slow Spanish: both sides castle, White delays d4, Black plays ...Be7 and ...d6. Plans are ...c5 or ...exd4 for Black, and a kingside bind or a central break for White. This is the Ruy people mean when they say it rewards understanding.
Strengths and costs
Why play it
- Lasting pressure instead of a one-move attack.
- You can choose the Exchange, a closed system, or something sharp.
- The same structures appear for years, so study compounds.
What you give up
- More theory than the Italian, especially against 3...a6.
- The Marshall and the Berlin are real study tasks.
- Easy to play too slowly and let Black equalise without a fight.
Common mistakes
Taking on c6 and then e5
4.Bxc6 dxc6 5.Nxe5 Qd4. That is the leak. The Exchange is a structure, not a pawn grab.
d4 with no support
c3 first, or a well-timed d4 after Re1. A loose d4-pawn in an open Spanish is a target.
Ignoring the queenside
Black’s play is often ...b5, ...Na5, ...c5. If you only look at the king, you lose a bishop or a pawn on the other side.
Walking into the Marshall unprepared
Decline it on purpose, or learn the first ten moves of the attack. Hoping is not a repertoire.

FAQ
Do I have to play the main line?
No. The Exchange and the d3 Berlin are complete repertoires for club play. The closed Morphy is the one that needs the most pages.
Why not just play the Italian forever?
You can. The Ruy is for when you want more than a hit on f7 — when you are happy to play a long game with a small plus.
