Two nice mates in best of 5

Played  a best of 5 against another chess.com player, and had two really fun mating patterns.  Posting it mainly for memory sake :)

In this one he resigned when there was forced mate, unfortunately -- but after this position he can't stop Qh7+, Qxg7#

And this game was a nice exploitation of an unsafe king, and weak light squares -- and who doesn't love a queen sac followed by mating with a pawn :)
