Small push x 2

I really need to get back to my 1 post a day routine, as I fear I am slipping in keeping this blog relevant. To help me do this, I've decided to look through games from current and recently finished events, looking to find interesting or quirky games. 

The one I have found for today's post is probably in the quirky category, as black does something I'm not sure I have seen that often. On two separate occasions he pushes a pawn one square (instead of 2) but then completes the two square push on the following move. The first pawn he does this with is the e pawn, and he then repeats the idea with the h pawn. The apparent loss of tempo doesn't seem to hurt, as it is another push of the h pawn that brings the game to a sudden finish.
