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.

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.

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
