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?"
Guest4027007 - Wall,B
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.d3 Nf6 5.Bxf7+
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.
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).
For the record, Guest1053350 - Wall,B, PlayChess.com, 2014 continued 7.c3 h6 8.Qb3+ d5 9.exd5 Na5 10.Qb5 Qxd5 White resigned.
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.
