About the Italian Game
After 1.e4 e5 2.Nf3 Nc6, White plays 3.Bc4, aiming the bishop at the weak f7 pawn. It teaches quick development and fast castling.
The quiet plan is c3, d3, O-O and later d4 to build a strong centre.
f7 is guarded only by the king, so watch for Ng5 and Qh5 tricks.
Black can reply 3...Bc5 (Giuoco Piano) or 3...Nf6 (Two Knights), both sound choices.
