The following rematch (see "Jerome Gambit: More Pie, Please ") shows Black, once again, ready for his opponent's Jerome Gambit.
Alas, he does not appear to have been completely ready for his opponent.
Wall, Bill - PassCapture
lichess.org, 2016
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb4+
We have seen this line before, most recently in Wall, Bill - NN
lichess.org, 2016 (1-0, 18). It is one of a number of ways that Black returns one of the two sacrificed pieces.
7.c3 Bxc3+ 8.bxc3 Ng6
As I have previously written:
The Knight... could also go the other way, although Bill has some experience with that plan as well: 8...Nc6 9.d5 (9.O-O Qf6 10.e5 Qg6 11.Qf3+ Ke8 12.Nb5 Kd8 13.Qf8+ Qe8 14.Qxe8+ Kxe8 15.Nxc7+ Ke7 16.Nxa8 Nxd4 17.Bg5+ Ke6 18.Nc7+ Kxe5 19.Rae1+ Kd6 20.Bf4+ Kc6 21.Rc1+ Kb6 22.Nd5+ Kb5 23.Rxc8 Ne6 24.a4+ Kxa4 25.Ra1+ Kb3 26.Be5 Black resigned, Wall,B-Caynaboos, FICS. 2011) 9...Ne5 10.f4 Ng6 11.h4 Nxh4 12.Qh5+ g6 13.Qxh4 Qxh4+ 14.Rxh4 Nf6 15.e5 Ne8 16.Be3 c6 17.O-O-O d6 18.e6+ Ke7 19.g4 Nf6 20.f5 gxf5 21.gxf5 cxd5 22.Bg5 a6 23.Nxd5+ Kf8 24.Bxf6 Rg8 25.Rxh7 b5 26.Be7+ Ke8 27.Nf6 checkmate, Wall,B - ChessFlower, PlayChess.com, 2012.
9.e5 Qe7 10.O-O Nh6 11.Bxh6 gxh6
This exchange is often a good idea, weakening Black's King's position and creating targets for White's Queen.
12.f4 d6 13.f5 Nh4 14.Qh5+ Kf8 15.f6 Qe6
The pesky "Jerome pawns" (backed by the Rook) work well with the White Queen.
16.Qxh6+ Ke8 17.f7+ Kd7 18.Qxh4 Rf8 19.Rf6 Qe7
(It is useful, once again, to point out how Black's light-squared Bishop remains on its home square, and, in turn, Black's Queenside Rook. White's development rules the day.)
20.Na3 dxe5 21.dxe5 Qxa3 22.Rd1+ Black resigned
Checkmate comes quickly after 22...Qd6 23.Rfxd6+ cxd6 24.Qf6.
The Jerome Gambit is full of "reasonable" lines of play for Black, and the defender has to be aware - is it a playable reasonable line, or an unplayable reasonable line; and then, more importantly, what comes next?
Wall, Bill - TenAndOnly10
lichess.org, 2016
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb6
This seems like a reasonable move, although not frequently played in comparison with other lines. It shows up in 111 games in The Database, where Black scores 50%. (Compare that to the 1,528 games with the same moves up until 6.d4, where Black scores 48%.)
Of course, any chance of catching Bill by suprise is likely to be small.

8.O-O Be6 9.Qf3+ Ke8 10.Nc3 a6 11.Be3 dxe5
For now White has only one pawn for his sacrificed piece, but Black's uneasy King comes close to making up the rest of the compensation.
12.Qh5+ Bf7 13.Qxe5+ Qe7 14.Qxg7 Qf6
15.Bh6 Bd4 16.e5 Qg6
This move allows White's pieces to become troublesome - enough so that Stockfish 8 suggests instead that Black give back the exchange with 16...Qxh6 17.Qxh8 Rd8 and then exchange some more pieces, e.g. 18.Ne4 Qg6 19.c3 Qxe4 20.cxd4 Bd5 21.Qg7 Ne7 22.Rfe1 Qg6 23.Qxg6+ hxg6 where White only has an edge.
17.Qf8+ Kd7 18. Qxa8 Qxh6
Black returns the exchange in his own way. The difference is that he is not now as equipped to protect his King.
19.Rfd1 c5 20.Qxb7+ Ke8 21.Qb8+ Ke7 22.Ne2 Bh5
23.Nxd4 Bxd1
A final slip.
24.Nf5+ Black resigned
Bill Wall has encouraged others to play the Jerome Gambit. The following game is between a friend of his - a teacher - in St. Paul and a student. It is a good example of a stronger player giving "Jerome Gambit odds" and the game is good source material for understanding about attack and defense.
teacher - student
Minnesota, 2017
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
White will offer a couple of pieces. Can Black defend?
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6
A common, reasonable defense - Black removes one piece from the line of fire, and returns the other, a time-honored recipe for dealing with a gambit. White has to be pleased, however, as Black has side-stepped some of the sharper, more challenging defenses.
7.Qd5+ Kf6
Stockfish 8 sees this move (at 30 ply) as about 1/4 pawn worse than the top alternatives, 7...Kf8 and 7...Ke8; but the text allows a certain amount of mischief to wander in - starting with White's next move.
8.d4
A stranger to the Jerome has to wonder - why is White again refraining from capturing the Bishop?
The piece is doomed, whether it sits or moves. White is giving some misdirection: the open c1-g5 diagonal is the reason behind his play.
8...Bb4+ 9.c3 Ba5
The Bishop is safe - but the King is not. Necessary was for the monarch to retreat along the d8-h4 diagonal, when the worried-about piece will fall after all.
10.Bg5 checkmate
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
lichess.org, 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
