1.e4 e5 2.Nf3 Nc6 3.Bb5 - See Ruy Lopez introduction.
3...Nf6 - The Berlin! Black immediately develops and attacks e4.
White's plans: Play d3 for a closed game, or O-O and d4 for sharp play.
Black's plans: Solid development, often leading to an early queen exchange after 4.O-O Nxe4.
Watch the moves to understand the opening sequence. Use the controls to replay or auto-play the variation.
