The Jerome Gambit can produce a no-holds-barred attack that decimates the defender. It can also provide an opportunity for the creation of weaknesses in the defender's camp - followed by patient play to take advantage of the minor "destructions".

One of the nice things about defending against the Jerome Gambit is that you have so many ways to return one of the sacrificed pieces.
7.dxc5 Nf6 8.Nc3 Re8 9.O-O Kg8
Black has every reason to be content with his position: he has a piece for a couple of pawns, and his King has castled-by-hand.
His only problem is that his opponent isn't interested in resigning - he wants to play until he wins.
10.Qd4 b6 11.Bg5 bxc5 12.Qxc5 d6 13.Qd4 c5
14.Qa4 Bd7 15.Qa6 Qb6
I suspect that Bill welcomed the opportunity to exchange Queens here, as he was able to create targets for his remaining pieces. His skill, and his experience with the Jerome Gambit, gave him a better understanding of how to play the game.
16.Qxb6 axb6 17.Bxf6 gxf6 18.Nd5
The game doesn't always have to be *Crash!* and *Boom!*. White's Knight targets weaknesses in Black's position, and the defender does not cover up well.
18...Rf8 19.Nxb6 Ra7 20.Rfd1 Bc6 21.Rxd6 Bxe4 22.Nd7 Rxd7 23.Rxd7 Bxc2
Black has two pieces for a Rook - and two pawns. The pawns are going to cause problems.
24.a4 Ra8 25.a5 Be4 26.a6 Nf8 27.Rc7 Ne6 28.Re7 Bd5 29.a7 Nd8
Black's Knight is almost to his defensive position at c6.
30.Rd1 Nc6 31.Rb7 Be6
A slip. The tireless Knight needed to take one more defensive leap, 31...Nd4, to shield the Bishop.
32.Rd6 Bc8 33.Rc7 Black resigned
Black's Knight is en pris, but cannot move to safety, as it protects against Rd8 checkmate.

Jerome Gambit: In the Style of World Champions
I suppose that chess purists would recoil from me suggesting that the following Jerome Gambit game seems to be influenced by the recent Caruana - Carlsen match for the World Chess Championship. White is comfortable allowing a Queenless middlegame and heads for a quiet endgame. Why not? He has the better game. It almost looks like he turned play over to the automatic pilot in his brain.
Wall, Bill - Guest5649018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.d4 Nf3+
I really like this move. It's no good, of course, and in the 7 games in The Database that contain it, White has 6 wins - and his lone loss was to a tricky checkmate in an endgame where the clock seems to have played a major part in stealing a well-earned "1-0".
Still, if Black has to give back a piece, you have to smile at his creativity - especially if he expected a pawn capture on White's next move.
7.Qxf3+ Qf6 8.dxc5 Qxf3 9.gxf3 Nf6
Apologies to Guest5649018, but this is the kind of position Bill could play while working on the New York Times crossword puzzle - even the Sunday edition.
10.Nc3 Rf8 11.Bf4 Ne8 12.Nd5 c6 13.Nc7 Nxc7
14.Bxc7 Ke6
The chances of reaching a drawn Bishops-of-opposite-colors endgame are very small.
15.Ke2 a5 16.a4 Rf6 17.Rag1 g6 18.h4 Black resigned
Perhaps Black has been following the World Championship match, as well. He sees that White is content to grind and grind... (It is also relevant, once again, to point out that Black's d-pawn blocks his Bishop, which blocks his Queen Rook - a fatal illness often found in Jerome Gambit games.)

Jerome Gambit: Overlooking Something
One of the scariest defenses to the Jerome Gambit is what I have called a pie-in-the-face variation. After 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.d4 comes 6...Qh4!?, first seen, as far as I can tell, in Sorensen - Anonymous, Denmark, 1888 (see "Jerome Gambit Tournament: Chapter X").
By the way, I do not think that Alonzo Wheeler Jerome ever faced 6...Qh4, or covered it in his published analysis.
The following game shows the power of the counter-attack, as well as at least one of its weaknesses. After all, Bill Wall is playing White; and, for the record, he has faced 6...Qh4 34 times, scoring 87%.
Wall, Bill - Guest8885375
PlayChess.com, 2018
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.d4
This was originally A.W. Jerome's choice, although he later moved on to 6.Qh5+.
6...Qh4
Here we go. White has sacrificed, but Black attacks.
7.O-O Ng4 8.h3 d6
Black's light-squared Bishop now hungrily eyes g4 and h3. How sad to see that Komodo 9 (welcome to the analysis team) sees the game as even.
9.dxc5 N8f6
More development! White isn't the only player who can sacrifice a piece.
10.hxg4 Nxg4 11.Bf4
White's Bishop arrives in time to protect h2.
The computer now suggests that Black retreat his Knight, and after 11...Nf6 12.Bg3 Qxe4 13.cxd6 cxd6 14.Qxd6 things have settled down, and White has an extra pawn. But why should Black's Knight retreat?
11...Rf8 12.cxd6 Kg8 13.Qd5+
Oh, okay, I get it: 11...Nf6 would have prevented this check.
13...Kh8 14.dxc7 Rxf4
Overlooking White's snappy response.
15.Qd8+ Black resigned
I suspect in his analysis Black saw that the d8 square was covered by his Queen, and so White's check would be harmless, but he missed the fact (in his chess vision?) that White's Queen would be protected by the pawn at c7, waiting for its chance to promote, i.e. 15...Qxd8 16.cxd8/Q+, with mate to follow.

Jerome Gambit: Yet Again, I Would Prefer Not To
The Jerome Gambit brings along with its sacrifices a certain amount of psychology - many defenders are surprised and/or shocked at the brutal and crude attack (What did I overlook in my opening preparation?).
Some defenders choose a defense along similar grounds: if White wants me to take the piece, I won't. I don't this is a strong approach for Black, but it certainly changes White's situation and goals. As we saw in the previous game, suddenly it is Black who is the gambiteer, and White who needs to adjust.
Wall, Bill - Guest5240605
PlayChess.com, 2018
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kf8
So: no Bashi-Bazouk attack. As I wrote, previously
5.Bd5
White retreats his Bishop. Some day, I should look at games in The Database where White leaves the piece on f7, and pursues the attack as if the sacrifice had been accepted.
5...Qf6
More development, and preventing d2-d4. "How do you like being the defender, Mr. Jerome Gambiteer?" Black hurls.
6.O-O d6 7.c3 Bg4 8.b4 Bb6 9.Na3 Bxf3 10.Qxf3 Qxf3 11.gxf3 Rb8
A lot has happened. White still retains his 1 pawn advantage, but it is a doubled on on f3. Neither side has an attack - but only one has the advantage, and he knows how to use it.
12.Nc4 Nf6 13.a4 a6 14.b5 Nxd5 15.bxc6 Nf6
We have seen an interesting skirmish on the Queenside, and I was surprised not to see White go for the Knight-for-Bishop exchange at b6. That is because Bill has a different idea, based on the location of Black's King.
16.Ba3 bxc6
It was a bit better to unpin the d-pawn immediately with 16...Kf7.
17.Nxe5 c5
Blocking the diagonal of the White Bishop, and thus activating the pawn threat against the White Knight. However, this leads to both strategic (the Bishop is stifled) and tactical issues.
18.Nc6 Ra8 19.a5
When we talk about annoying "Jerome pawns", we usually overlook the a-pawn. But, for today, a little applause.
19...Ba7 20.e5
Here you go.
20...dxe5 21.Nxa7 Kf7
A sad necessity, for it 21...Rxa7, then 22.Bxc5+, picking up the Rook on the next move.
Now, White gets to play on with an extra piece, first consolidating his position.
22.Nc6 Rhe8 23.Bxc5 Kg8 24.d4 exd4 25.cxd4 Nd5 26.Rfe1 Rec8
Black does not want to exchange Rooks and move a step closer to a bad endgame, but this move is unfortunate. The Knight fork on e7 is a constant threat.
27.Re5 Rd8
Retreating the Knight falls to 28.Ne7+.
28.Rxd5
Same idea.
28...Rxd5 29.Ne7+ Kf7 30.Nxd5 Black resigned
So: even in the Jerome Gambit Declined, there are tactics to beware of!

At the same time, it is useful to point out Bill Wall's statistics on the matter: for 4...Kxf7, Bill has 509 games, scoring 92%. It only gets better for 4...Kf8, with 6 games and White scoring 100%.
It is probably fair to add: I have only faced 4...Kf8 once, and I lost.

Jerome Gambit: I Would Prefer Not To
The Jerome Gambit, from an "objective" standpoint, has to be considered a wonderful gift to the defending player - the gift of at least one piece, sometimes two. After all, the opening has been refuted many times - what more could Black want?
Yet, sometimes, the gift is not accepted. Consider the following game.
Wall, Bill - Guest9273483
PlayChess.com, 2018
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kf8
As Herman Melville's character Bartleby, the scrivener, said, "I would prefer not to."
I was surprised to see 312 games with this position in The Database. I was even more surprised to see that White scores only 56%. Still, that is an improvement over the results for the main line 4...Kxf7 - 14,373 games in The Database, where White scores 46%.
At the same time, it is useful to point out Bill Wall's statistics on the matter: for 4...Kxf7, Bill has 509 games, scoring 92%. It only gets better for 4...Kf8, with 6 games and White scoring 100%.
5.Bb3 Nf6
In this position we must imagine that Black is the gambiteer, and that he has given up a pawn for a slight lead in development (a somewhat larger lead, if we consider his King to be developed).
6.Nc3 Nd4
Instead of the principled 6...d6, planning to develop his light square Bishop, Black decides to be a bit tricky, no doubt planning to answer 7.Nxe5 with 7...Qe7. Bill is not interested, though, and simply safeguards his King.
7.O-O Nxb3 8.axb3 d5
You have to admire Black's confidence - open lines for his pieces, attack the center. Still, he did not get much for his first "sacrificed" pawn, and he does not get much for this next one, either.
9.exd5 Bg4 10.h3 Bh5 11.g4 Bg6 12.Nxe5
12...Be8
The alternative, winning back a pawn, was not attractive: 12...Bd4 13.Nxg6 hxg6 14.Kg2 Bxc3 15.dxc3 Qxd5+ 16.Qxd5 Nxd5 White would be up a couple of pawns, have a Bishop for a Knight, and have pawn majorities on both sides.
13.d4 Bb4 14.g5 Nxd5 15.Qf3+ Black resigned
Black's Knight is attacked twice and defended only once; it wil perish.
Yet, sometimes, the gift is not accepted. Consider the following game.
Wall, Bill - Guest9273483

Tournament Update: Ahead of the Scrum
As J.M. Barrie wrote in Peter Pan,
All of this has happened before, and it will all happen again.And, so it is that, once again, somehow - thank you, Jerome Gambit - I find myself at the top of the heap in my section in the second round of the "Italian Battleground" tournament at Chess.com.
With one game not yet completed, it looks like I will be followed in the standings by four players who will each have the same score. It will be up to the tie breaks to decide which two, among warwar, docfb, manospawn, and vasbur, will join me in advancing to the third round. (I won a Jerome Gambit against warwar, the only player in this group to allow the opening. If he is interested in a return match, I supect he is happy to have the edge in the tie breaks at this point.)
In the other section, two games remain to finish, but XristosGikas and 275Jukka have secured their advance, while Abhishek29 and Alfonso10 are likely to be the ones relying on tie breaks to secure an advance for one of them.
If my predictions hold, I am likely to be the 4th highest rated amongst the final 6 - but, then again, I will have my secret weapon.
