Great Queen Sac
This mating pattern should not be attempted from this position. The Knight on c6 throws a wrench in White's plans. After 1.Nxe5 Nxe5, Black is up a piece for a pawn and White's Queen is still en prise. This should be played only if Black knights are not on c6 or f6. In that case, after dxe5, White is a pawn up and is building strong pressure.
