Didn't see it coming

The European Club Championship has just started, and it is often a chance for regular club players to mix with the super GM's in the same event. Of course this 'mixing' may involve a severe beating at the hands of a 2700+ GM, but I'm sure that the following game proves that it could happen to anyone.
Gashimov demolishes Gelfand's Petroff in 16 moves, after the latter chose the wrong moment to castle. I'm guessing that it probably wasn't opening prep, as the game had deviated from book some moves earlier, but these days you never know.

Gashimov,Vugar (2740) - Gelfand,Boris (2756) [C43]
