About the Bishop's Opening
After 1.e4 e5, White plays 2.Bc4 at once, aiming at f7. White keeps options open for f4 or a quiet Italian-style game.
White often plays d3, Nf3, c3 and O-O, then pushes d4.
Black's best reply is 2...Nf6, attacking e4 right away.
Black can also hit back with ...d5 to gain time against the bishop.
