The following game features Bill Wall, who has scored 95% with various Jerome variations - facing the Gambit.
Black wins so easily, one has to ask "What's the problem?"

White transposes into one of the "modern" Jerome Gambit variations which does not feature Nxe5+. Recent blog posts have shown Bill winning in this manner.
5...Kxf7 6.Ng5+
This is not the preferred way to continue the attack.
A check of The Database shows that Bill has scored:
8-0 with 6.0-0;
3-0 with 6.Nc3;
2-0 with 6.Be3; and
0-1 with 6.c3 (looks like a fluke).
6...Kg8 7.0-0

Black has a piece for a pawn. All he has to do is swap pieces and enjoy a winning endgame. Bill makes it look easy.
