A typical sacrifice

In the game below, White was already in big trouble when he attempted to exploit the pin on my knight with 8.Ne4?? 8...Nxe4! was a typical sham sacrifice. After 9.Bxd8 Bb4+, Black will regain the sacrificed material with interest. In the final position, the threat of 15...Nd2 double check and mate was enough to induce my opponent to resign.
