Ruy Lopez
The Ruy Lopez (Spanish Opening) is one of the oldest and most thoroughly analyzed openings in chess, beginning with 1.e4 e5 2.Nf3 Nc6 3.Bb5. White pins the knight defending e5, applying long-term positional pressure. The opening has featured in world championship matches for over a century and remains the gold standard of classical 1.e4 play.

Key Ideas
- White's main plan is d2-d4, breaking the center after proper preparation with c3 and Re1.
- Black should counterplay with ...Na5-Bc2 or ...Nd7-Nf8-Ng6, maneuvering the pieces to better squares.
- The b5 pawn gains queenside space but also creates a hook — White can target it with a4.
- The Ruy Lopez bishop on b3/a2 is a long-term strength, always eyeing the f7 weakness.
- Black's setup is solid but slightly passive — the key is timing the counterattack correctly.
- The battle for the d5 square is central: White wants to plant a piece there; Black must prevent it.
