How often do you succeed with sacking a piece for a mating attack?

I tend not to do it, but when my opponent does not have a lot of pieces that can defend... it usually works...

1-2% of the time.

@chessanalyst same here.

Well, it's a surprise tactic then :D

sacrifice for a checkmate (33.Rxh7+)

I sacrificed 2 rooks when my opponent dropped his queen (time pressure) but about 5%

The games where you do that and win look amazing, but when it dosnt work... then, omg... it horrible :D I know from experience xD

Well it depends.
How much time left does my opponent have on the clock? :P

In this game I sacrificed my queen to force a back rank checkmate.

Well, what is a piece when you can get a craw pawn?
