I want to quote from GM Alburt, as it could be applied to the Jerome Gambit, as well.
When is it OK to use traps that may be somewhat unsound? First, the potential punishment your well-prepared opponent can mete out to you should be relatively mild, while your reward (should he fall into your trap) should be much bigger. Two, at least three out of ten (30%) of your current opponents should go wrong! (When you are faced with the unenviable task of repeatedly defending a worse position rather than enjoying the fruits of your cleverness, it's time to quit. You've outgrown this particular trap.)
From my students' experience, the trap below (3...Nd4) works well up to the 1400 level. (Even higher in blitz: your opponent might be able to recall/find the right way, but it may cost him too much time for his comfort.)Something to think about.
