Tragicomedy with major pieces

Here's the 2nd round game between NM Eric Rosen and NM Adarsh Jayakumar from this weekend's Denker Qualifier.  As both players had dropped points in the first round, the loser would be eliminated from contention for first. 

Rosen-Jayakumar, Skokie 2011 
Black to move

So you're playing the Black pieces in the position above.  You've just made the "standard" rook for five pawns sacrifice, and White's king is walking.  But you're living off the thirty-second increment, which means you've got to come up with the best move quickly.  What do you do?

Look for the answer (and annotations) on the ICA website  in a few days.

Special thanks to Adarsh Jayakumar for seeing the humor in this painful loss!
