Interesting Tactical Sequence in the Four Knights

I've been playing the Petroff, and quite often my opponents transpose into the Four Knights - a very tactical game that can get very complicated.

This comes out of a move - or combination of moves -  that White played against me in one of my games, an f4 pawn push that allowed an interesting double check - but computer analysis (starting after f4) shows a very rich tactical sequence if Black takes up the challenge. If Black doesn't give back material by trading the Queen back for a rook, then White has a draw by perpetual check!

So: my moves up until move 14, and then some degree of truth (and beauty!) in chess.

Enjoy!
