Jerome Gambit: The Improved Fork Trick

Next to the "I have never seen this before!" reaction of some players defending against the Jerome Gambit, the "Oh, this looks familiar!" has to be an equally frequent response. There is always the risk, however, of moving too quickly and falling into an "improved" Fork Trick, as Bill Wall shows in the following game. 

Wall, Bill - Vicher, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bd6

This position has a resemblance to that of the "fork trick", and that may be the reason Black opted to move the Bishop where he did. However, the placement of his King makes for a significant difference in the play White can develop.

7.dxe5 Bxe5

As planned, but transforming a roughly equal position to one definitely better for White. (Omigosh! How did that happen?? Black had a won position after 5 moves!)

8.Qd5+ Kf6

Yes, Bill has been here before: 8...Kf8 9.Qxe5 d6 (9...Qe7 10.Qf4+ Nf6 11.Nc3 d6 12.O-O Qe5 13.Qxe5 dxe5 14.f4 exf4 15.Bxf4 Ne8 16.Bd6+ Kg8 17.Rf8 checkmate, Wall,B - Guest539122,, 2015) 10.Qd4 (10.Qb5 Nf6 11.Nc3 c6 12.Qd3 Be6 13.Bg5 h6 14.Bh4 g5 15.Bg3 Ke7 16.O-O-O Ne8 17.f4 g4 18.Bh4+ Nf6 19.e5 dxe5 20.Qg6 Qf8 21.fxe5 Black resigned, Wall,B - NN,, 2016) 10...Nf6 11.O-O c5 12.Qd3 Bd7 13.Bf4 a6 14.Bxd6+ Kf7 15.e5 Bb5 16.c4 Black resigned, Wall,B - Guest5856753,, 2016.

Or 9...c6 10.Qxe5+ Kf7 11.O-O Qe7 12.Nc3 d6 13.Qh5+ g6 14.Qe2 Nf6 15.e5 Nd5 16.Nxd5 cxd5 17.Qb5 dxe5 18.fxe5+ Kg7 19.Qxd5 Re8 20.c3 Qxe5 21.Qf7+ Kh8 22.Bg5 Qxg5 23.Qxe8+
Kg7 24.Qf8 checkmate, Wall,B - Neilson,C, Melbourne, FL, 2016.

Or 9...Bd6 10.Qg5+ Kf7 11.Qxd8 Black resigned, Wall,B - NN,, 2016.
