The following game shows Black unveiling a surprise line, only to be met by White's surprise. The defender continues with another surprise on move 6, but cool play makes the difference in the face of complications.
Wall, Bill - Emankcin
Playchess.com, 2017
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4
The Blackburne Shilling Gambit. White has several ways of effectively meeting the idea, including 4.0-0, 4.d3, 4.c3 and 4.Nxd4. Black's main idea is revealed with 4.Nxe5 Qg5!?.
Of course, Jerome Gambit fans also like to give the game their own twist.
4.Bxf7+
The Blackburne Shilling Jerome Gambit.
4...Kxf7 5.Nxe5+ Ke8 6.c3 Qg5
Black plays his thematic move. It might not be as strong as 6...Nc6, leading to an even game, but it certainly gives White something to think about. The Database contains 125 games with this position; White scores 57%.
For coverage on the line in this blog, see "Surprise!", "Too Fast, Too Furious" and "A Head Scratcher".
7.cxd4 Qxg2 8.Qf3
Calmly meeting Black's play.
8...Qxf3 9.Nxf3 d6
White has an extra pawn, and although it is doubled, it is a center pawn. Black has the two Bishops. The position would seem to slightly favor the first player - but it mostly favors the player who can come up with an effective plan.

11.Ke2
Signalling that White wants his King to be active.
The one other game in The Database with this line is also complicated: 11.Nh4 Be7 12.Ng2 Bf3 13.Rg1 g6 14.d3 Kd7 15.Bf4 Nf6 16.Kd2 a6 17.Rae1 b5 18.Ne3 b4 19.Ncd5 Nxd5 20.Nxd5 a5 21.e5 dxe5 22.Nxe7 exf4 23.Rg5 Rhe8 24.Rge5 Ra6 25.d5 Rd6 26.Nc6 Rxe5 27.Nxe5+ Kd8 28.Nxf3 Rxd5 29.Re5 Rxe5 30.Nxe5 Ke8 31.h4 Kf8 32.Ke2 Kg7 33.Kf3 Kf8 34.Kxf4 Black resigned, Papaflesas - Tseatsy, FICS, 2015.
11...Nf6 12.d3 Kd7 13.h3 Bh5 14.Bf4 Re8 15.Ke3 d5
Black's strike at the center makes sense, especially with his Rook on the e-file, facing White's King; but it has the shortcoming of opening e5 for White's pieces.
16.Ne5+ Kc8 17.f3
White is in no hurry. He reinforces his center and lets his opponent come up with the next new idea.
17...dxe4 18.dxe4 c5
19.Rad1
Developing another piece. An alternative was 19.d5, creating a second connected passed pawn that would eventually help decide the game..
19...Kc7
Perhaps a time slip: Black's King walks right into a discovered check.
Instead, Black could win the exchange with 19...cxd4+ 20.Rxd4 Bc5. Stockfish 8 is not particularly concerned about this, however,
still seeing White as better after 21.Nb5 Bxd4+ 22.Nxd4. White has the open c-file for his Rook, and a pawn or two on the Queenside should prove vulnerable.
20.Nf7+ Black resigned
Play likely would continue 20...Kc6 21.Nxh8 cxd4 22.Rxd4 Bc5 23.Rc1 Bxd4+ 24.Kxd4 Kd7 when 25.Nb5!? gives Black too much to think about, e.g. 25...Rxh8 26.Rc7+ or 25...Bxf3 26.Rc7+
Sometimes a player will find a path through the forest that is the Jerome Gambit. Later, others will clarify the way. In the following game, Bill Wall makes the way a bit clearer.
Wall, Bill - Nikelin
lichess.org, 2017
1.e4 e5 2 Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bd6
7.dxe5 Bxe5
The best response was 7...Bb4+.
8.Qh5+ Ke6 9.Qf5+ Kd6 10.Na3
This is right, the Knight should go to a3, not c3, as we shall see.
10...Qf6
In HauntedKnight - VSRajput, FCIS, 2015, White had the right idea in responsing to 10...Bf6, but then lost his way: 11.Nc4+ Ke7 12.Bf4 d6 13.Qb5 Qe8 14.O-O-O Qxb5 15.b3 Be6 16.Ne3 Qb4 17.g4 Qa3+ 18.Kd2 g5 19.Bg3 h5 20.h4 gxh4 21.Bxh4 hxg4 22.Bxf6+ Nxf6 23.Rxh8 Rxh8 24.f4 gxf3 25.Rf1 Nxe4+ 26.Kd3 Ng5 27.c4 Qxa2 28.Re1 Qxb3+ 29.Kd2 Ne4+ 30.Kc1 Qc3+ 31.Nc2 Nf2 32.Kb1 Kf6 33.Rf1 Rh1 34.Rxh1 Nxh1 White resigned

12...d6 13.Bxf6+ gxf6 14.Qf3 Black resigned
The following game shows the benefit of going further off the beaten path in an already unusual opening. Bill Wall varies from previous experience, and continues to find success. The notes suggest that Black could have found chances by varying his play, too. The game ends with a bit of psychological mind-reading.
Wall, Bill - NN
lichess.org, 2016
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bd6
This strategy is not unusual and seems reasonable, although it does have a tactical flaw. The Database shows that it has been faced by Jerome Gambit regulars such as chessmanjeff, HauntedKnight, frizerkaHR, jfhumphrey, stretto, Teterow and yorgos.
Oh, and of course, Bill Wall.
7.dxe5 Bxe5
Better is 7...Bb4+ (no game examples in The Database), 7...Bf8 (no game examples in The Database) or 7...Be7 (20 game examples in The Database, White scores 45%); each moving the Bishop out of danger of a Queen check/fork.

Bill tries something new, deviating from his previous 8.Qd5+:

8...g6
An interesting alternative is 8...Ke6 9.Qf5+ Kd6 10.Na3!?, which may have seemed riskier to Black, but which would put White more on his own resources. There are two examples of the line in The Database: 10...Qf6 (10...

9.Qxe5 Nf6 10.Bg5
Putting pressure on the Knight at f6, a regular strategy for White in the Jerome Gambit.
10...Re8 11.Qf4
White could have played the prosaic exchanging 11.Bxf6+ Qxf6 12.Qxf6+ Kxf6 13.Nc3 with a pawn advantage. I think he realized that his opponent saw the White e-pawn as pinned by the Black Rook to the White King, and played for the win of a piece.
11...b6 12.e5 Black resigned
The threat by White's advanced pawn is real. One possibility: 12...d6 13.Bxf6 dxe5 14.Bxe5+. It is worth taking time to explore other lines, too.
I have chosen the following Jerome Gambit game to be illustrated by a series of diagrams. The first shows an opening oversight by both players - where White's Queen could have been won before move 10.
The remaining diagrams show the game after it has reached a pawns endgame. The computers say the first player has the advantage - but how does he win?
Black's drawing method is worth remembering.
ainafets - cmdeats
blitz, FICS, 2007
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 Qf6 8.0-0
White slips, as covered in "Something To Watch Out For" and "Why Did He Play That Move?" - although Black overlooked his opportunity on the next move.
A game played 10 minutes after this one, on the same date, continued with the same tactical theme, only this time Black caught on: 8.f4 Nf3+ White resigned, ainafets - Papaflesas, FICS, 2007.
Later on, the players reached the following position. White has recovered nicely, and reached a winnable endgame.
23.Kf2 Ke6 24.Kf3 Ke5 25.c3 a6 26.h4 h6 27.h3 g6 28.b3 c6
White is in no hurry, and slowly advances his pawns, avoiding anything drastic.
29.b4 c5 30.a3 h5 31.a4 d5 32.exd5 cxb4 33.cxb4 Kxd5 34.e4+ Kc4 35.b5 axb5 36.axb5 Kxb5
The Queenside pawns have been exchanged off - maybe not the most efficient solution, but leaving much less for White to worry about. He still has a won game.
Houdini actually evaluates the position as a "checkmate in 18 moves" for White, but average players don't have to calculate that far to see a winning plan. The only "trick" is that the first player must realize that it needs to be his e-pawn that gets promoted.
37.Kf4 Kc5 38.Kg5 Kd4 39.Kxg6 Kxe4 40.Kxh5 Kf5
White has a 2-0 pawn advantage, but, due to the nature of those pawns - both Rook pawns - he now has only a draw. Instead, 38.Ke5, followed by shepherding the e-pawn to the 8th rank, was the way to go.
But - don't go away yet.
41.Kh6 Kf6 42.Kh5 Kf5 43.Kh6 Kf6 44.h5 Kf5
Having shown his opponent that he understands how to hold the draw - by keeping White's King trapped on the h-file in front of his pawns - Black suddenly has his King give way.
White now wins by springing his King with 45.Kg7.
45.h4
Or, not.
45...Kf6 46.Kh7 Kf7 47.h6 Kf6
Again, Black falters. (It was, after all, a blitz game.) Holding the draw was 47...Kf8.
48.h5
And White, too, misses another chance to free his monarch. So the point gets split.
48...Kf7 49.Kh8 Kf8 50.Kh7 Kf7 51.Kh8 Kf8 52.h7 Kf7 53.h6 Kf8 Game drawn by stalemate
Continuing my search through The Database's 8-move games, chasing clues to the "essence" of the Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+, (or at least an insight into how it "works"), I came across a lesson (again) for White, written in a handful of games.
After all, 7...Qf6 could simply be an example of Black placing a strong piece on a strong square. Or – he could be planning something...

It is so much easier in a scary movie: you know that you are moving into danger when the background music becomes ominous, perhaps the screeching of violins...
In a chess game, especially when playing a dubious opening like the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) it is important to be aware of dangerous themes.

9.g3 Nf3+ White resigned
Danger is everywhere, and we must learn to recognize it.
I have been watching the early movies of the Marx Brothers, and I have to say that they are pretty serious about their silliness. In a similar way (except for my glaring lack of talent) I can be rather serious about the silliness that is the Jerome Gambit (and its relatives).
Fortunately, not everyone is.
HauntedKnight - sarahdaniel
blitz, FICS, 2011
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
The good old Jerome Gambit. I've researched its history, analyzed its lines, annotated games and gathered a large database.
As Chico might say, "Why a duck?"
4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bd6
This unusual defense seems to be borrowed from the "fork trick".
The Database has 41 games with this line. White scores 61%.
7.dxe5 Bxe5 8.Qh5+
This is the strongest line for White. It is interesting to note, however, that in the 24 games with 8.Qh5+ in The Database, White has scored 54%.
Yes, that's right: the best move scored worse than the lesser alternatives.
8...Ke6 9.Qf5+
Again, this is the strongest continuation of the attack for White; yet it appeared in less than 1/4 of the games in the 6...Bd6 line: 10. In those, White scored only 50%, a result less succesful than that of the worse alternative moves combined.
Happily for HauntedKnight his opponent now responded with
9...Resigns.
Other games from The Database continued. We will look at them, too.
9...Kd6
10.Na3
This is White's strongest move, planning a Knight fork to the enemy King and Bishop, with check, winning a piece. It is not easily met, but after 10...Bf6 11.e5+ Ke7 12.exf6+ Nxf6 13.Bg5 d5 14.Bxf6+ gxf6 15.Qf3 followed by 0-0 or 0-0-0 White will have equalized in material while having the better pawn structure and safer King.
analysis diagram
Instead of the text, 10.f4 is very Jerome-ish. With 10...Bf6 Black can return the piece (i.e. 11.e5+) for an even game. The contest wzeller - bourgas, FICS, 2005 instead entered the world of "optical illusions" with 10...Qf6 11.fxe5+ Qxe5+ 12.Bf4 and White won (1-0, 62).
10.Nc3 is not dangerous enough, although White won against 10...a6 in jfhumphrey - jrhicksdotnet, FICS, 2008 (1-0, 14). The better defense 10...Qf6 brought Black victory in jfhumphrey-biryuk, FICS, 2010 (0-1,65) and duanezz - pawelek, FICS, 2005 (0-1, 38).
Likewise, 10.0-0 also falls to 10...Qf6 but not as often as expected. White's plan is to continue his attack on the King with 11.Rd1+, and after 11...Ke7 12.Bg5 he was successful ("optical illusions" again!) twice: EvanJunior - BeNumberOne, FICS, 2008 (1-0, 22) and AGRPlayer - trebbor, FIC, 2010 (1-0, 19). However, Black's King should escape the Rook check to fresh air with 11...Kc6 instead and then White cannot conjure up either an attack or a recovery of material, as seen in carlkrull - bodensee, FICS, 2009 (0-1, 28).
10.b3 contains a great little trap – if Black now takes the Rook with 10...Bxa1 he is checkmated after 11.Ba3+ c5 12.Qxc5+ Ke6 13.Qf5# – but the proper response, 10...Qf6 White could not escape in ljar - Castled, FICS, 2006 (0-1, 39)
10...Qf6
Not the strongest response, as indicated in the note to 10.Na3, but certainly one that White can expect to see.
11.Nc4+ Ke7
Falling in with his opponent's plan too quickly. He should have at least tried 11...Kc5, since after 12.Nxe5 Qxf5 13.exf5 White's advantage is only a doubled pawn. After the better 12.Qxe5+, however, Black needs to cooperate with 12...Qxe5 13.Nxe5, as the obstreperous 12...Kxc4 – which may have been Black's intent – falls to chekmate after 13.b3+ Kb4 14.c3#.
12.Qxe5+ Qxe5 13.Nxe5 d6
White is a safe pawn up in a quiet position.
