A tactical mess

Playing through Eickelman-Slade from the club championship, I came across this position in analysis.

Eickelman-Slade (analysis)

White to play

Far afield of any position from the game itself*, Black has played 28...Bc5xf2 attempting to win White's queen and create even more chaos on the board. What should White's response be? Just giving the first move only gets partial credit.

* Seriously, gentlemen, good luck figuring out how I got here!
