Opponents facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) would do well to be prepared. Even if the opening is officially "refuted", any old response will not do. The following game is a good example of how things can quickly go bad for the defender.
The games in the notes provide additional proof that Black needs to be careful.

Interestingly enough, the same moves were played in youngrema - Stella-chan, lichess.org, 2020.
The following game is a good example of how defense - especially defending against an attack on the King - is more difficult than attack. Black has ways for his King to escape punishment, but he is not able to find them, and the game ends as many gambits end, successfully for the attacker.

9.Nb5+ Kc6 10.Qxe5 Kxb5
Black can capture the Knight, but it would be safer to play something like 10...d6 or 10...Qe7.
11.a4+ Kc6
Maybe now Black thinks he can get in ...d6, but it is too late for that. He needs another plan. He could have tried 11...Ka6 12.Qxc5 b6!? and his King can escape to b7.
12.Qd5+ Kb6 13.a5+ Kb5
Again, Black would have helped himself more with 13...Ka6, this time answering 14.Qxc5 with 14...d5 (14...b6 is not as effective) 15.b4 Qd7 16.0-0 and White has an edge, although a checkmate isn't available.
However, after the text, it is.
14.c4+ Kb4 15.O-O
Good enough.
You might want to work out the alternative: 15.b3 Qf6 16.Ba3+ Kxb3 17.Qd3+ Ka4 18.Bb2+ Kb4 19.Bc3+ Kb3 20.Bxf6+ Kb4 21.Qc3#.
15...c6
16.Qd3 Bxf2+ 17.Rxf2 d6 18.Qc3+ Kc5 19.d4 checkmate
The position after the 15th move in the following game is worth a close examination. It is clear that White has gotten enough in return for his material sacrifices, but the compensation is not in terms of a loose or hanging piece that will soon be scooped up - it is in the unrelenting pressure on the Black King. But, does he have more than an even game?

A recent alternative, also designed to keep White's Knight out of d5: 10...Nf6 11.O-O Kf7 12.d4 c6 13.f4 Re8 14.e5 Ng4 15.Qf3 Nh6 16.f5 Bxf5 17.g4 Nxg4 18.Qxg4 Kg8 19.Rxf5 dxe5 20.Bg5 Qe6 21.Re1 Rad8 22.Bxd8 Rxd8 23.dxe5 Rd2 24.h4 Rxc2 25.h5 Nf8 26.Rxf8+ Black resigned, odoaker2015 - Marienkaefer24h, lichess.org, 2020.
11.f4 a6 12.O-O Nf6 13.e5
White is in a hurry, otherwise he could have gotten in 13.d4, first.
13...dxe5 14.fxe5 Nxe5 15.b3 Ned7
This is a very interesting Jerome Gambit position. Black has an extra piece, White has an extra pawn. Black's King is unsafe, however, and there is the typical defensive flaw: his Knight blocks his Bishop, which, in turn, blocks in his Rook. White's development is much more effective.
What can the first player do? First, there is the decoy sacrifice, 16.Ba3!?. After 16...Qxa3 17.Rae1 g6 18.Ne4 Kg7 19.Nxf6 Nxf6 20.Rxf6!? Rf8 21.Rxf8 Qxf8 22.Qd4+ Kg8 23.Qc4+ Kg7 24.Qd4+White forces a draw by repetition.
If Black is unhappy with this outcome, he can play 17...Qc5, and, after 18.d4 Qh5, 19.Qe7+ Kg8 20.Rxf6!? gxf6 21.Re3 he will see that his opponent has full compensation for his sacrificed Bishop and Rook, and Black will have to sue for peace, himself, with 21...Qd1+ 22.Kf2 Qxc3+ 23.Kg1Qb1+ 24.Kf2 Qc2+, etc.
White could also try something a little less flashy, say 16.Ne4 Kf7 17.Bb2 Re8 18.Rae1, but after 18...Qxe4 19.Qxe4 Rxe4 20.Rxe4 his Rook and pawn would balance out Black's 2 Knights, for an even game.
All of which probably at least partially explains the move White chose, which may not have been as powerful, but was easy to understand.
16.Qf3 h6 17.a4
The Bishop would like to go to a3, without sacrificing itself. The calm move seems to have misled Black.
17...Rg8 18.Ba3 c5 19.d4
Hitting the pinned pawn at c5. As in the notes above, 19.Rae1 was quite powerful.
19...b6
It is time to recall that this is a 5-minute blitz game.
20.a5
Undermining the pinned c-pawn.
20...Rb8 21.axb6 Nxb6 22.Bxc5 Qxc5 23.dxc5 Nbd7
White's plan to win the Queen has succeeded.
24.b4 Rxb4 25.Qc6 Rb8 26.Qd6+ Kf7 27.c6 Kg6 28.cxd7 Bxd7
29.Rxf6+ gxf6 30.Qxd7
The rest is mopping up.
31...Rbd8 31.Qg4+ Kh7 32.Qf5+ Rg6 33.Rxa6 Rdg8 34.Ra7+ Kh8 35.g3 R8g7 36.Rxg7 Kxg7 37.Nd5 Rg5 38.Qd7+ Kg6 39.c4 h5 40.c5 Rxd5 41.Qxd5 f5 42.c6 Kg5 43.c7 h4 44.gxh4+ Kxh4 45.c8=Q f4 46.Qcg8 Black left the game
White has enough time to be sure he avoids stalemate.
When putting together a Jerome Gambit repertoire, it is useful to have access to both "objective" evaluations - say, from a computer chess engine - and "subjective" evaluations - as from a collection of games that can tell you how successful a line has been. Often a move that is not "objectively" best may score very well in actual play. The following game, and its notes, illustrate this.

6...Kxe5 7.f4+ Kxe4
One of the reasons White plays 6.Qg4, is so that if Black grabs the Knight, he can offer more material with 7.f4+, because if Black grabs the e-pawn... What happens next??
Don't worry. White was asked this question 24 times in The Database, and only scored 50 %.
Wait until next time! That's why I analyze games and share them.
8.d3+ Kd5 9.c4+ Kc6 10.O-O Nc2
There is nothing exactly wrong with this move, but shouldn't Black be thinking about safeguarding his King, not grabbing more material? If I were White, even though I was down 2 pieces, I would feel a stirring of hope.
11.Qf3+ Kb6 12.Qf2+ c5
Proof that Black considers the game already won. Otherwise, what move would he have played that definitely would have produced "resigns"?
13.Qxc2 Qf6
Amazingly enough, now, with 14.Nc3 (with the plan to go to d5) White would equalize.

The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) has become popular with club players, of late, and certain lines have become very popular. The following game is an example of the kind of attack that can develop, but there are some good recent games in the notes, too, that are worth playing over, as well.
