About the Ruy Lopez
After 1.e4 e5 2.Nf3 Nc6, White plays 3.Bb5 to attack the knight that defends e5. It is one of the oldest and richest openings.
White builds slow pressure: O-O, Re1, c3 and then d4 to win the centre.
Black usually kicks the bishop with ...a6 and ...b5; it retreats to a4 and then b3.
Bxc6 does not win e5 at once, because Black wins the pawn back with ...Qd4 or ...Qg5.
