Hunting for Mistakes * VICICKÓ, Zoltán vs. me

After White's last 13.f2-f4
it is Black to move

The game was played in an open tournament in Szerencs, Hungary, on Aug-21, 2009.
I was the second player and failed to find the winning move. (which would still have been a part of a known opening trap by Black in the Philidor Defence)

Try and guess the move-sequence that wins the game for Black on the spot. (please write your solution as a comment to this entry)
