18... Kc7 and although you have some compensation for the piece, there are not enough open files on the queenside for your attack to work.
Excellent point, but I suppose at the time the urge to sac it was overwhelming, I guess it could be attributed to the fact that I had previously lost to my opponent in a game before and I wanted to win in a flashy fashion.
