For much of the game Black is doing well, and when he slips, it is only to "fall" to an even game.
Then he loses heart...

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8
Given by Alonzo Wheeler Jerome in his published analysis in the July 1874 issue of the Dubuque Chess Journal; and played successfully by him in two correspondence games against Daniel Jaeger in 1880.
Strangely enough, The Database, with 23,645 Jerome Gambit and related games, does not have this reasonable move.
8.d3 Qf6 9.Qg3 d6 10.Nc3 Nh6
Planning to target White's f2 square.
11.0-0 Ng4 12.Be3
Encouraging Black to follow through with his plan, i.e. 12.h3 Bxf2+ 13.Rxf2 Qxf2+ 14.Qxf2+ Nxf2 15.Kxf2, while "objectively" a little bit better than the text, would have left White with a pawn for the exchange, when Black would have an edge.
My move makes Urumpel nervous about his King and Queen being on the same file as my Rook.
12...Kg8 13.Bxb6 axb6 14.f4
14...Ra5 15.h3 Qd4+ 16.Kh1 Ne3
This invasion looks dangerous, but only leads to an even game. Black should have considered developing his other Rook with the Fishing Pole-style 16...h5!?
Not nearly as powerful a move now.
Yielding too quickly to despair.
Black sees his Knight going, and uses it as a desperado, forgetting that his Queen is en prise. He could have used the same idea to find 18...Nf5, when 19.exf5 Qxb2 20.Qe3 Kf7 21.Ng3 Re8 22.Qf3 Bxf5 23.Qxh5+ g6 24.Qf3 Be6 would have left White only slightly better, according to Rybka 3.
