Caissa's pearls.

In this position from a blitz game black is winning easily but the queen is in a spot of bother and cumbersome attempts to save her failed - eventually white won on time. The missed knockout is 16. ... 0-0-0!  solving everything with the threat of Nc3 dbl check and mate to follow.

Caissa casts her pearls and we  poor mortals are like the proverbial swine before her.
