A sinister swindle

I'm a pretty good swindler, to the point where I consider my swindling abilities to be among the most valuable skillsets in my chess.  I'd bet that it wins me more games than my (largely absent) endgame technique.  This game I played featured a swindle with an aesthetically appealing checkmate.  The game was one of a series of 15 blitz games I played all in one sitting one night, where I went on a tear and won 13 and lost 2.  

The game begins as a Smith Morra Gambit, and I play the attack energetically, building up a large advantage.  Then I began to falter and had to fall back on my swindling skills to secure the win after blundering.  This is a theme I see cropping up frequently in my blitz play that I need to figure out how to do something about: once I secure a large advantage, I often get lazy and play imprecisely, subconsciously thinking that the hard work must be over.  I have no doubt that I would have found the move 18. Be3 in a classical game, but in a blitz or a rapid game sometimes these kinds of logical conversion moves elude me.  I was considerably inebriated while playing, but that's no excuse- I should be seeing these moves sober or otherwise. 

Aside from 18. Be3, there was 18. Rxe7 Qxe7 19. Bc7+, as well.

yes good one
