Recently I received some Jerome Gambit games from long-time unorthodox openings expert Bill Wall. He pointed out
My chessbase database says I have played 352 Jeromes without transposition and I just now discovered the statistics page with a 93% winning advantage. I have 168 games with 6.Qh5 (90% winning percentage) and 138 games with 6.d4 with a 90.6% winning percentage. Pretty even.
I have now played 50,817 chess games that I have a recorded game since 1969. I should hit 51,000 before the end of the year.
One reason (besides skill and knowledge) that Bill does so well with the Jerome Gambit is that his opponents do not take the opening seriously - to their dismay, as he does.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

This is trouble. The Bishop could have gone to e7 or f8, with or without checking at b4 first.

8...Kf6
Not the only, or safest, way to move the King. There was: 8...Kf8 9.Qxe5 d6 (9...Qe7 10.Qxc7 [10.Qf4+ Nf6 11.Nc3 d6 12.O-O Qe5 13.Qxe5 dxe5 14.f4 exf4 15.Bxf4 Ne8 16.Bd6+ Kg8 17.Rf8 checkmate, Wall,B - Guest539122, PlayChess.com, 2015] 10...Qxe4+ 11.Kf1 d5 12.b3 d4 13.Ba3+ Ne7 14.Nd2 Qe6 15.Re1 Qd7 16.Bxe7+ Black resigned,Wall,B - Guest851465, PlayChess.com, 2017) 10.Qb5 (10.Qd4 Nf6 11.O-O c5 12.Qd3 Bd7 13.Bf4 a6 14.Bxd6+ Kf7 15.e5 Bb5 16.c4 Black resigned, Wall,B - Guest5856753, PlayChess.com, 2016) 10...Nf6 11.Nc3 c6 12.Qd3 Be6 13.Bg5 h6 14.Bh4 g5 15.Bg3 Ke7 16.O-O-O Ne8 17.f4 g4 18.Bh4+ Nf6 19.e5 dxe5 20.Qg6 Qf8 21.fxe5 Black resigned, Wall,B - NN, lichess.org, 2016.

Apparently offering to return the piece, after all, once White has played the fork 10.e5+.
Black has tried other moves against Bill, as well:

Here is the last game of the Philidor1792 - Slayman match, testing a particular opening. With a time control of 2 0, the outcome rests on any number of things, including the "33rd piece" - the clock.
Again: a 2-minute game is almost too fast for me to breathe, let alone play interesting chess. Nice work, gentlemen.
Philidor1792 - Slayman
2 0 bullet, lichess.org, 2017
1.e4 e5 2.Bc4 Nf6 3.d4 exd4 4.Nf3 Nc6
After the first three moves we have come to expect, White tosses in 4.Nf3 and Black adds 4...Nc6, bypassing the Urusov Gambit and moving on to the Two Knights Game, although lichess.org labels the line "Scotch Game: Scotch Gambit, Dubois Reti Defense".
5.Bxf7+
The Jerome-ish sacrifice.
5...Kxf7 6.e5 Ne4 7.c3 d5
Again, White seeks to develop after 7...dxc3 8.Nxc3, and again Black does not cooperate - this time moving his other d-pawn.
8.cxd4 Bb4+ 9.Nbd2 Rf8 10.O-O Bxd2 11.Bxd2 Kg8
Black has castled-by-hand and retains his extra piece.
White's protected passed "Jerome pawn" is not yet a factor in the game.
12.h3 Be6
(In a slower game it would be worth pointing out 12...Rxf3 13.Qxf3 Nxd2 )
13.Be3 Qe8 14.Rc1 Qh5
15.Kh2
White sees there will be trouble on the Kingside, but might have done better to offer the exchange of Queens with 15.Ng5.
15...Bxh3 16.Ng1 Qxd1
Black does White a favor. The Queen exchange takes the energy out of the attack - but it also makes calculation in the position a bit easier; and the second player still maintains his advantage.
17.Rfxd1 Be6
Black has the extra piece - but the clock is ticking away.
18.f3 Rad8 19.fxe4 dxe4 20.Ne2 Nb4 21.Rxc7
When in doubt, and time trouble, grab material.
Stockfish 8 recommends the rambling line 21.Nf4 Bg4 22.Rd2 c6 23.Kg3 Bf5 24.Rf2 Nd3 25.Nxd3 exd3 26.a4 h6 27.Rcf1 Be4 28.b4 Rxf2 29.Rxf2 Bd5 30.Rd2 Bc4 31.Rf2 g5 32.Rf1 Kg7 33.Rf2 Rf8 34.Rxf8 Kxf8 35.Kf2 Ke7 36.Bc1 Ke6 which it sees as favoring Black, but which looks pretty drawish due to Bishops-of-opposite-colors.
21...Nd3
Not enough time to figure out 21...Nd5 22.Rc3 Bg4 23.Rd2 Bxe2 24.Rxe2 Nxc3 25.bxc3 Kf7 and the extra exchange helps Black.
22.b3 White won on time.
Continuing to present the games from the bullet match at lichess.org between Philidor1792 and Slayman, using the unusual Jerome Gambitish line mentioned a couple of posts ago - see "Jerome Gambit: Strange Beast".
Philidor1792 - Slayman
2 0 bullet, lichess.org, 2017
1.e4 e5 2.Bc4 Nf6 3.d4 exd4 4.Bxf7+
Here we go. Philidor1792 was successful with this line in this rocket-fast match, winning three games, drawing one, losing none.
4...Kxf8 5.e5 Ng8
As we have seen, the best defense starts with 5...Qe7 6.Qe2 Ne8. However, in a 2 0 game you barely have time to breathe, let alone analyze deeply. Knowing anything about the line is a great advantage.
6.Nf3 Bc5 7.c3 d3
Black has no intention of helping White's development with 7...dxc3 8.Nxc3.
8.Qxd3 Bb6 9.O-O Ne7 10.Qc4+ Kf8 11.Bg5 h6 12.Bf4 Rg8
"Objectively" Black is better, with a piece for a pawn, but his position is horribly cramped and undeveloped.
13.Nbd2 g5 14.Bg3 Nbc6 15.Ne4 Nf5 16.Nf6 Nxg3
Yipes! This overlooks a checkmate-in-two.
17.Qxg8+ Ke7 18.Qg7+
Move, move, move! Missing 18.Nd5#. Move, move, move!
18...Ke6 19.hxg3 Nxe5 20.Nxe5 Qxf6 21.Qxf6+ Kxf6
In a game with a slower time control, exchanging Queens would not be the best plan. Here White is up the exhange, and he can calculate better (and faster) with fewer pieces on the board.
22.Nc4 d5 23.Nxb6 axb6 24.a3 Be6 25.Rae1 c5
Black needs to activate his Queenside pawn majority.
26.Re3 d4 27. cxd4 cxd4 28.Re4 Rd8 29. Rd1 d3 30.Rd2 Bf5
31.Rb4 Rc8 32.Rxb6+ Rc6 33.Rxc6+ bxc6 34.f3 Ke5 35.Kf2 Kd4
36.g4 Bg6 37.g3 Kc4 38.Ke3 Kb3
39.Rxd3+
An option always available to the one ahead the exchange.
39...Bxd3 40.Kxd3 Kxb2 41.Kd4
Nice. White could have decided to run his a-pawn, but after 41.a4 Kb3 42.a5 c5 43.a6 c4+ 44.Ke4 c3 45.a7 c2 46.a8/Q c1/Q both of the Queens are back on the board, and calculation becomes a bit more time-intensive. Only the clock can beat White now, so he keeps it simpler.
41...Kxa3 42.Kc5 Kb3 43.f4 Kc3 44.f5
Now there will be only one Queen on the board, and White only needs one...
44...Kd3 45.f6 Ke4 46.f7 Kf3 47.f8=Q+ Kxg3 48.Qxh6 Kxg4 49.Kxc6
Alas for Black, if his remaining pawn were either the f-pawn or h-pawn - and more advanced - he would still have drawing chances. Was not to be...
49...Kg3 50.Qxg5+ Kh2 51.Qg4 Kh1 52.Kd5 Kh2 53.Ke4 Kh1 54.Kf3 White won on time
Each player spent around 2 seconds per move.
Following up on the previous post (see "Jerome Gambit: Strange Beast"), Philidor1792 sent me four games he recently played with the line (as White) in a match against Slayman, at lichess.org, at the quick speed of 2 minutes with no increment per game. Philidor1792 scored 3 1/2 - 1/2.
It is fun to first look at the two shortest - and funniest - games.
Philidor1792 - Slayman
2 0 bullet, lichess.org
1.e4 e5 2.Bc4 Nf6 3.d4
This is identified at lichess.org as "Bishop's Opening: Ponziani Gambit".
3...exd4 4.Bxf7+
This is not a Jerome Gambit, but it has a Jerome feel about it, and certainly is equally outrageous.
Of course, White also had 4.Nf3, offering the Urusov Gambit; and Black could have further declined with 4...Nc6, the Two Knights Defense.
4...Kxf7 5.e5 Ne8
The proper defense, maintaining Black's advantage, as shown in saprvade - Philidor1792, 3 2 blitz, lichess.org 2016 is 5...Qe7 6.Qe2 Ne8 etc.
6.Qf3+ Kg6
I was amused to see that Stockfish 8 assessed the silly alternative, 6...Nf6, as completely equal (0.00), recommending the equally silly 7.Qd1, even with an analysis depth of 25 ply.
Of course, Stockfish is confused by the possibility of repeating the position, resulting in a draw - just play the two moves and the computer leaps to point out, of course, that Black is better by 2 2/3 pawns.
After the text move, however, Stockfish 8 assesses the top 6 replies by White to lead to complete equality (0.00) again.
7.Nh3 h6 8.Nf4+ Kf7
Remember: this is a 2-minute game, and any retreat probably looks the same as any other retreat. But: not so.
The proper line was shown in another one of the games in the match: 8...Kh7 9.Qe4+ Kg8 10.Qd5+ Kh7 11.Qe4+ Ke8 12.Qd5+ Kh7 13.Qe4 drawn (by repetition).
9.Qd5+ Ke7 10.Ng6 checkmate
I just received a game from Philidor1792, and although it is not a "regular" Jerome Gambit, it is related, or "inspired by" - and it blew my mind. It features a pretty scary gambit, completely "objectively" unsound, but very uncomfortable to play against.
You have been warned.
saprvade - Philidor1792
3 2 blitz, lichess.org 2016
1.e4 e5 2.Bc4 Nf6 3.d4 exd4
So far we have a variation of the Bishop's Opening, Berlin Defense. The position could also arise from the Center Game, von der Lasa Gambit, 1.e4 e5 2.d4 exd4 3.Bc4 Nf6.
Now White can play 4.Nf3 and hope to transpose into the Urusov Gambit, although Black has 4...Nc6, moving the game into a Two Knights Defense or Scotch Gambit.
4. Bxf7+
Say what??
I could find no game examples in The Database, or in the ChessBase Big Database 2016. A Google search online was of no help.
Philidor1792 pointed me toward the database at lichess.org, where I discovered that there were 41 games (including 1 0 bullet games and 3 0 blitz games) where White scored 51%.
4...Kxf7 5.e5 Qe7 6.Qe2 Ne8
Philidor1792 is a long-time Jerome-Gambit-and-related player. He knows what he is doing with Black, but the position already looks quite uncomfortable. Remember, too, this is a 3 2 blitz game.
7.Nf3 d6
Black's move is logical, but is a slip. Best seems the immediate safeguarding of the King with 7...Kg8 e.g. 8.Nxd4 and Stockfish 8 suggests the tortured continuation 8...c5 9.O-O Nc7 (if 9...cxd4 then 10.Qc4+ d5 11.Qxc8 Qd7 12.Qxd7 Nxd7) 10.Nf5 Qe6 11.Ne3 Nc6 12.f4 b6 13.c4 Nd4 and "of course" Black is "winning". Nice work if you can get it, as they used to say.
analysis diagram
8.Ng5+ Kg8
Of course this seems reasonable, but, as Philidor1792 points out, if 8...Kg6 then 9.e6 Bxe6 10.Nxe6 Kf7 11.Nxd4 Nc6 (or 11...Qxe2+ 12.Nxe2 Nc6) 12.Nxc6 Qxe2+ 13.Kxe2 bxc6 with an equal game.
Of course. Easy as pie, in the blink of an eye.
analysis diagram
9.Qc4+ Be6 10.Nxe6 Qf7 11.Qb3 Nd7 12.Nxd4 dxe5 13.Nf3 Bc5 14.Nc3 Qxb3 15.axb3 Nef6
Black has pretty much weathered the storm, although White has an edge due to a slightly better pawn structure and a safer King.
16.O-O Kf7 17.Re1 Rhe8 18.Be3 Bd6 19.Bxa7 b6 20.Nb5 Rec8
White's Queenside adventures do not seem to be amounting to much.
21.Red1 Kg8 22.Nc3 e4 23.Nd4 Nc5 24.Ncb5 Nb7 25.Nc6 Bf8 26.b4 Nd6 27.Nxd6 Bxd6
White is still a bit better, but not by very much. What in the world are his minor pieces doing?
28.c4 Nd7 29.Rxd6 cxd6 30.Ne7+ Kf7 31.Nxc8 Rxc8 32.b3 Ra8
33.Kf1 Ke7 34.Ke2 Kd8 35.c5 bxc5 36.bxc5 dxc5 37.Ra3 Kc7
This looks like a time slip. If the Jerome-ish opening doesn't get you, the clock will...
38.Bxc5 Rxa3 39.Bxa3
Facing a Bishop vs a Knight, and an outside passed pawn, Black can only hope his opponent's flag falls, but it does not do so - although almost 40 more moves are played.
39...Kc6 40.Ke3 Kd5 41.Bb2 g6 42.b4 Nf8 43.b5 Ne6 44.Ba3 Nd8 45.Be7 Nb7 46.Kf4 Ke6 47.Bf8 Kd5 48.Kg5 Ke6 49.Kh6 Kf7 50.Bb4 Kg8 51.Kg5 Kf7 52.Kf4 h5 53.Kxe4 Ke6 54.Kf4 Kf6 55.b6 g5+ 56.Ke4 Ke6 57.f4 gxf4 58.Kxf4 Kf6 59.Bc3+ Kg6 60.Ke5 Nc5 61.Kd5 Nd7 62.b7 Kf5 63.Kd6 Nb8 64.Be5 Na6 65.Kd5 Nb4+ 66.Kc5 Nd3+ 67.Kd6 Nxe5 68.b8=Q Nc4+ 69.Kc5 Ne5 70.Qh8 Ng6 71.Qxh5+ Kf6 72.Kd6 Nf8 73.h4 Ng6 74.Qg5+ Kf7 75.h5 Nf8 76.Qe7+ Kg8 77.h6 White resigned
The following game has a line in the Jerome Gambit (Delayed?) that I am not very familiar with, so I consulted with The Database and Stockfish 8 for some assistance. It is good to see jfhumphrey move quickly to victory.
jfhumphrey - ckilee

1.e4 Nc6 2.Nf3 e5 3.Bc4 Bc5 4.O-O
4...Nf6
Transposing to a Two Knights Defense (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6) with ...Bc5 added.
The Database has 1,148 games with this position, with White scoring 42%. (For comparison, The Database shows White scoring 45% after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+)
5.Bxf7+ Kxf7
Now The Database has 1,909 games with this position (oh, the joys of transposition) with White scoring 40%.
6.Nxe5+ Nxe5 7.d4
The Database has 291 games with this position, with White scoring 45%.
7...Bd6
Now, however, The Database has 35 games with this position, with White scoring 71%. From a practical point of view, Black has made an error that generally gets punished.
Interestingly enough, Stockfish 8 sees the text move as giving White less than a half of a pawn advantage. It prefers 7...d5, and this is backed up by The Database, which has 10 games with that move - all of them wins for Black.

Abject humiliation.
I just completed a 10 0 online blitz game with the Jerome Gambit.
I won on time.
I won't annoy my opponent by giving his name.
For historical purposes, here is the final position when his flag fell (with Black to move, mind you). I don't need Stockfish's help to figure this one out.
I know that I have shown other Jerome Gambit players escaping similarly, but it's a bit different when it is my game.
What kind of a role model is that?
I have half a mind to take up knitting.
