Locock Gambit

The Locock Gambit is a very aggressive line in the Philidor Defense and starts with the moves:

1.e4 e5
2.Nf3 d6
3.d4 Nf6
4.Ng5 h6
5.Nxf7

The Philidor Defense is generally pretty passive. When you start out with e5 and d6 you are playing for a very long game by building up a strong pawn structure. This can be very frustrating for many players starting out with e4 because they are looking for an aggressive start.

With the Locock Gambit, white is able to regain the initiative and play a very aggressive line. The knight is sacrificed and in exchange, white is able to launch a strong attack against black
