If you play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) you know that the best source of information on the opening is this blog.
If you face the Jerome Gambit, however, the best source of information on defending against the opening is - this blog.
Across the 10 years that I have shared history, games and analysis, I have done my best to give the lines that give White the greatest opportunities to snatch victory from the jaws of this defeated - er, "refuted" - opening.
I have also not shied away from presenting the various refutations, as well.
Sometimes players have used my suggestions. Sometimes they have not. The "Jerome Gambit Secrets" posts will re-visit suggestions that appear to remain unplayed. Occasionally, they will introduce new suggestions. Take for example, the following game.
MIG - jfer
3 0 blitz, FICS, 2001
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian opening. Black is careful to prevent Ng5 by White.
4.Nc3 Bc5 5.Bxf7+
The Semi-Italian Jerome Gambit.
5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ g6 8.Qxe5 Bd6
Perhaps Black remembered ...g6 from the Blackburne defense, and felt comfortable giving up the Rook on h8. If so, this game is not the best example of analysis by analogy. Maybe the 3-minute blitz game was going so fast...
9.Qxh8 Nf6 10.Qxd8 Be7 11.Qxc7 Black resigned
Okay, no disrespect to the players, but the game did not show either at the top of their skill level. Again, perhaps the time control was a major factor.
Still, Black could have offered the Rook with a different 8th move: 8...Bf8!?. White would take his Queen's life in his hands if he continued 9.Qxh8? Bg7 10.Qh7 Nf6 and Her Majesty is a goner.
The Database has a half-dozen games with the same position after 8.Qxe5 - all wins for White. In none of the games did Black find the dangerous Bishop retreat. (The Database needs some updating, but, when it is, I am confident that 8...Bf8 will not show up there.)
Stockfish 9 suggests a complicated line that leaves White with 3 pawns for his sacrificed piece, but still gives Black the advantage: 8...Bf8!? 9.Nd5 Nf6 10.Nxc7 d6 11.Qc3 Rb8 12.d3 Bg7 13.Qb3+ Ke7 14.Nb5 a6 15.Nd4 Nxe4 16.Qb4 a5 17.Nc6+ Kf8 18.Nxa5 Nf6 19.0–0 Nd5 20.Qb5 Be6 21.Re1 Bf7 22.c4 Nc7 23.Qb4 Na6 24.Qd2. I like Black's Bishop pair.

Jerome Gambit: Naughty Opening
I have a Google Alert set up to notify me about the appearances of the name "Jerome Gambit" on the internet.
This morning it returned a link to a discussion on Reddit.com started by Chessmusings, that leads off
My favorite "naughty opening" is the Jerome Gambit. What's yours?
Cool. I appreciate the mention of my name, and this blog as well.

Jerome Gambit: Jerome Pawns Run Riot
Often White gets "only" 2 pawns for a sacrificed piece in the Jerome Gambit. Yet, if the defender is not careful, those "Jerome pawns" can run riot all over his position.
This latest game from "Cliff Hardy" is a brutal example of such pawns.
By the way, it is also another lightning game - 1 minute to complete the game, no increment. In such situations, a quick appraisal of the position in front of you is essential, and experience in what to look for and value is an advantage. Cliff takes a critical look at his - and his opponent's - moves, but it is all in the service of sharpening his eye for his next Jerome Gambit encounter.
The following notes are his. I have added diagrams. - Rick
Happy birthday yet again, now you've reached the age of ten!
I liked the following game as the Jerome pawns were quite successful in it. If only you could force opponents to defend against the Jerome Gambit like you can in a Giuoco Piano themed tournament, like the one in which I played this game, where the first 3 moves for White and Black were obligatory.
I know I am a little critical of the moves sometimes, but when you are looking at the game afterwards with the help of the Stockfish chess engine, it can be easy to be critical 😉.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6?!
7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Be6?! =+
It appears my opponent is not used to defending against the Jerome Gambit as this bishop is running headlong into the pawn fork f2-f4-f5 - 9...Nf6 instead would have kept a clear advantage for Black.
10.0-0 N8e7?! +=
Surprisingly, this defensive move was a big error that allowed my Jerome pawns a bit too much latitude - 10...Nf6 11.f4 Ne7! would have restrained the white pawns and kept a slight advantage for Black.
11.f4 Bd7 12.d4 Rf8 13.f5 Nh8
13...Nh4 moves in Jerome Gambit games often run into the pawn move g3, trapping the knight, so my opponent chose to retreat to the corner instead.
14.Nc3 Nf7!
Restraining the Jerome pawns.
15.Qg3 Rg8 16.Bf4?! +=
Even though it could be captured there by a knight, putting the bishop to g5 would have been much more incisive, with a clear advantage for White.
16...Nc6 17.Rad1 Qe7?
Black struggled to find a liberating move under the strain of the Jerome pawns - 17...g5!? would have been an interesting attempt to free himself.
18.Nd5 Qd8 19.c3 Ne7 20.Nxe7?!
20. Ne3! would have kept Black cramped and left White with a clear advantage.
20...Qxe7
21.e5
The Jerome pawns start going on a rampage.
21...dxe5 22.dxe5?
Too much rampaging! 23.Rde1!, keeping open the options of taking on e5 with either the pawn or bishop, would have kept a clear advantage for White.
22...Bc6?
Black missed a chance here - 22...Bxf5 would have turned the tables and left black with a slight advantage.
23.e6 Nd6 24.Bg5??
I was staggered to find out after the game that this was a big blunder - 24.Bxd6 cxd6 25.f6! ++- (intending fxe7 or f7+) would have been a fitting triumph for the Jerome pawns.
24...Qf8?? ++-
24...Ne4! 25.Bxe7 Nxg3 26.hxg3 Kxe7 -++ would have been much better, when the extra bishop for Black would likely have proven to have been decisive.
25.Qe5 g6
Now the Jerome pawns run riot completely though Black was totally lost anyway - he can hardly move a piece.
26.f6 h6 27.f7+ Nxf7 28.exf7 checkmate
Suitably, a Jerome pawn got to complete the mate.

Good Old Uncle Jerome
Chris Torres, of the online site Chess Musings, sends "a game I just played where I forced a Jerome Gambit where it didn’t belong. 😉 "
Check it out.
chessmusings - Stefanrapp
internet, 2018
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.c3 Bc5 5.Bxf7+
Good Old Uncle Jerome... You can't take him anywhere without him causing some kind of disturbance.
Here, Black was looking for a quiet game, the kind of thing you would reach after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5, and he even tossed in ...h6, so that, after White's c3, the game would be even quieter.
Alas, White sports some Jerome mischief with 5.Bxf7+.
It is interesting to note that while the computers clutch at their silicon pearls after such a move, Stockfish 9 suggests, instead, 5.b4 Bd6 6.O-O Nge7 7.d4 Ng6 8.dxe5 Ngxe5 9.Nxe5 Bxe5 10.b5 Na5 11.Bxf7+ - Good Old Uncle Jerome, late to the party, but still livening things up.
5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ke6
8.d4 Nd3+
As happens in many a Jerome encounter, Black has a few ideas that are interesting and correct. But this does not end the discussion.
9.Kd1 Be7
But this move clearly does.
10.Qd5+ Kf6 11.Qf5 checkmate
Like with many conversations, Black is left muttering "What I should have said was..."

Jerome Gambit: Think About It - When You Can
Here is the latest "Cliff Hardy" Jerome Gambit game, another 1-minute wonder.
Do not be distressed by "Cliff's" objective, if sometimes gloomy, appraisal of White's position. It is important to understand what he was thinking - and what he was missing.
As the time limit for a game shrinks, strong players move closer and closer to choosing their moves mostly by intuition - and then supporting them through analysis - when there is time. What follows is another lesson in the application and limits of intuition.
This was a fun game.
Cliff Hardy (2111) - NN (1988), 1 0, Lichess, 2018
What is the popularity like of this move in your database/s again, Rick? I face it a lot in this particular position - it feels like maybe 75% of the time that I have this position, I encounter the move 6...Ng6.
(I just checked with The Database, in games starting 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+:
6...Ng6 shows up in 46% of the games;6...Ke6 appears in 25% of the games;
6...Kf8 is played in 15% of the games; and
6...g6 is played in 12% of the games.
I guess many defenders see 6...Ng6 as a common sense move - block the check, save a piece, say goodbye to the other piece because White must know what he is doing & therefore "must" get a piece back, as no real opening lets White sac 2 pieces...-Rick)
7.Qd5+ Kf8 8.Qxc5 d6 9.Qe3 Nf6 10.0-0 Qe7
(This is a small improvement for Black over earlier defenses Cliff has faced: 10...Ke7 in Hardy - NN, Italian Game Bullet Arena, lichess.org, 2018 [1-0, 37]; and 10...Ng4 in Hardy - NN, 3 0 blitz, Chess.com, 2017 [1-0, 19] and Hardy - Pomo12, 10 0 blindfold, lichess.org, 2018 [0-1, 67] - Rick)
11.Nc3 c6?! =+
This looks OK to me, but not to the Stockfish computer program and when I encounter real top eschelon players in the Jerome, they find stronger moves like 11...Kf7! -+ (aiming for 12...Re8, with quick pressure against the white centre) against me, even in lightning games.
12.f4 Bd7? +-
Another move which fails to pressure white's position - 11...b5 would have maintained equality.
13. f5? Ne5 =+
I have a lot of trouble in these Jerome positions figuring out whether to play f5 first or d4 first and then f5 and here again I chose the wrong way - 13. d4 +- would have been very good for White.

14. d4 Nf7!
Holds the Jerome pawns up well.
15.Qf3? -++
Quickly developing with 15.Bd2 Rae8 16.Rae1 =+ would've been better.
15...Re8! 16.Re1 b6? =+
15...Re8! 16.Re1 b6? =+
Harmless - counter-attacking with 16...c5 -++ would've been better.
17.g4? -++
The less committal 17.Bf4 =+ would've been safer.
17...h618.h4 c5! 19.g5 hxg5 20.hxg5 Nh5 21.Nd5 Qd8
17...h618.h4 c5! 19.g5 hxg5 20.hxg5 Nh5 21.Nd5 Qd8
22.g6? Nh6??
It was fun for me to rain the Jerome pawns down but 22...Qh4! -++ would've shown the vulnerability of the exposed white king here.
23.f6??
I guess we both missed the possibility of 23.Qxh5 here - oops!
23...Nxf6 24.Bg5 Ng8 25.e5 dxe5 26.dxe5
26...Be6?? -+
I thought I had some good pressure here but 26...Bg4! -++, intending to take on d5 with the queen, would have been a crusher.
27.exf6 gxf6?? ++-
27...Qxd5 -+ unfortunately would still have refuted my position.
29. Re3??
29.Kg2 ++- would have been best here.
29...Nxf6??
29...Rh3! -+ (intending tricky stuff like 30.Qf2 Nxf6 31.Rxh3 Qxf2+ 32.Kxf2 Ne4+! 33.Kg1 Bxh3) was a hard-to-see win for Black.
30.Bxf6 Qxf6??
Sacrificing the queen with 30...Qxe3+ was losing, but was Black's only chance to keep the game going on for much longer.
31.Qxf6+ Kg8 32.Rxe6 Rf8 33.Re8! and Black lost on time
However, White had a checkmate coming here with Rxf8, Qxf8 or Qf7, so Black was dead anyway.
I had another couple of games against this opponent after this one. Unfortunately, the next game in which he was black, he didn't chance playing against the Jerome Gambit and played the French Defence instead.

Jerome Gambit: Sink the Putt
I play chess. I do not play golf. My guess is that facing a "refuted" chess opening in chess - say, the Jerome Gambit - is kind of like hitting a long shot to the green in golf. In the end, you still have to sink the putt. Likewise, even against 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+, Black has to still go on and finish the "win".
The following game is yet another example of Black coming up short.
Wall, Bill - Guest5607084
PlayChess.com, 2018
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4
An excellent response, very much like a pie in the face. (You can tell it is strong, as, in 33 games, Bill has scored "only" 86%.)
7.O-O Ng4
Wow. Looks scary.
8.h3 N4f6 9.dxc5 d6
Opening a line for another piece to enter the attack.
10.cxd6 cxd6 11.Nd2 Qh5 12.Nf3
12...Ne8
A move that is difficult to comprehend. I would guess that Black originally planned 12...Nxe4, but at the last moment saw that the move would be well met by 13.Ng5+. Still...
13.Ng5+ Kg6
14.g4 Qh4 15.e5
15...h6 16.Qd3+ Bf5 17.Qxf5 checkmate
Nyuk nyuk nyuk...
