Vienna Game - A checkmate to remember

Playing the Vienna game, I've come across this hard to spot checkmate as the board seems all jumbled in a middle game battle.  Can you find a move that might lead to checkmate in 3 moves?

Offer the queen...

In an analysis I ran across this a few months ago, after playing the Vienna game for a few years.  I've only had a chance to try it for a few games.  In my last game, the opponent saw it and took the knight.  Even though it's a potential trap (maybe one can pull it off if the move is quick to deceive it as a hurried mistake), it showed me there maybe a potential win lurking in a non-obvious spot.
