Ruy Lopez
C90 · Ruy Lopez: Closed · you play White
The idea
Pressure the knight that guards e5. The bishop drops back to b3 and c3 prepares d4.
The moves
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 8. c3 O-O

When they go another way
- If they play 3...Nf6: Castle and let Black take e4: the rook on e1 wins the pawn back and your pieces come out first.
