Let's go over that mental checklist (see yesterday's "I think I have a win, but it will take time...") for playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) again: surprse, inattention, over-confidence, shallow analysis and a well-timed unfortunate blunder...
I was doing fine until that last one.

1.e4 e5 2.Nf3 Nc6 3.Bc4 a6
Wow. Didn't Karpov play something like this in his match against Korchnoi in 1981? (Actually, he played it on move 5 in one game and move 6 in another. Oh, well.)
4.0-0 h6
Okay.
5.Nc3
From a practical point of view, White might do best to head toward a Scotch Game or Gambit with 5.d4, counting on the tempos gained by Black's Rook pawn moves.
5...Nf6
A few years ago, my patience was rewarded – with a delayed Jerome Gambit – after 5...Bc5 6.Bxf7+ Kxf7 7.Nxe5+ Nxe5 8.Qh5+ Ke6 9.Qf5+ Kd6 10.d4 Bxd4 11.Rd1 c5 12.Ne2 Kc7 13.Nxd4 d6 14.Ne6+ Bxe6 15.Qxe6 Nf6 16.Bf4 Re8 17.Qb3 Nxe4 18.Bxe5 Rxe5 19.Qf7+ Qd7 20.Qf3 Qf5 21.Qxf5 Rxf5 22.f3 Ng5 23.Re1 Kd7 24.Rad1 Re8 25.Rxe8 Kxe8 26.Rxd6 Re5 27.Kf2 Ke7 28.Rb6 Rf5 29.Rxb7+ Kf6 30.Rb6+ Kf7 31.Rxa6 Ne4+ 32.Ke3 Nd6 33.Rxd6 Ke7 34.Rd3 Rh5 35.h3 Re5+ 36.Kf2 g5 37.Re3 Rxe3 38.Kxe3 Kd6 39.Ke4 c4 40.Kd4 Black resigned, perrypawnpusher - angelosgoulianos, blitz FICS, 2007.
6.d3 Bc5
Finally! He plays it after I've already played d2-d3...
Wait a minute. If he's "wasted" two moves, can't I afford to "waste" one move myself?
Sure, why not??
7.Bxf7+
Ahhh, that feels better...
I suppose that this is a Delayed Semi-Italian Four Knights Jerome Gambit.
7...Kxf7 8.Nxe5+ Nxe5 9.d4
9...d6
Reminiscent of my game against FrankMCMLVII.
10.dxc5 Bg4
Okay, this guy is definitely playing with my head. The text move is good for Black, but the simple 10...dxc5 was even better.
11.f3 Bh5 12.g4 Nexg4
Not unexpected, but after the game Rybka preferred 12...Bg6, suggesting further 13.f4 Nexg4 14.cxd6 Qxd6 15.Qxd6 cxd6 16.h3 Nxe4 17.Nxe4 Bxe4 18.hxg4 h5 19.g5 Bxc2 with Black better by a pawn.

13.fxg4 Bg6
14.g5 hxg5 15.Bxg5
I did not see it at the time, but White is better here, especially if he can get in Qd1-d5+, something that Black prevents with his next move.
15...dxc5 16.Qf3
After the game Rybka recommended 16.e5 Qd4+ 17.Qxd4 cxd4 18.Nd5 which wins a piece for White.
16...Qd4+ 17.Kh1 Qe5
Black's centralized Queen now gives him counter-chances and equality.
18.Bxf6
Wow! Speaking of "a well-timed unfortunate blunder..."
The position would wind down after 18.Bf4 Qxe4 19.Nxe4 Bxe4 20.Qxe4 Nxe4 21.Bxc7+ Nf6

18...Qxh2 checkmate
When I play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) I realize that several of my "allies" during the game, which I hope afflict my opponent at every move, are: surprise, inattention, over-confidence, shallow analysis and a well-timed unfortunate blunder.
It should not be surprising, then, that my opponent expects the same of me – after all, I am the one playing the Jerome Gambit!

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian Opening.
4.0-0 Bc5 5.Bxf7
The Semi-Italian Jerome Gambit.
5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ g6
This is similar to the 6...g6 defense in the Jerome Gambit, leading to the Whistler and Blackburne variations.
8.Qxe5 Be7
In other games, twice my opponents have blocked my attack on the Rook, leaving me the Bishop to capture: 8...Nf6 9.Qxc5 d6 10.Qe3 Ng4 (10...Qe8 11.Nc3 c6 12.d3 Be6 13.f4 Ke7 14.f5 gxf5 15.exf5 Kd7 16.Qxe6+ Qxe6 17.fxe6+ Kxe6 18.Bd2 Kd7 19.Rxf6 Black resigned, perrypawnpusher - wadada, blitz FICS, 2009 ) 11.Qf4+ Kg7 12.d4 Rf8 13.Qg3 g5 14.Nc3 c5 15.f4 cxd4 16.Ne2 Ne3 17.Bxe3 dxe3 18.Qxe3 gxf4 19.Nxf4 Qg5 20.Nd5 Qxe3+ 21.Nxe3 Be6 22.Nf5+ Bxf5 23.exf5 Rae8 24.Rae1 Rxe1 25.Rxe1 Rxf5 26.Re7+ Kf6 27.Rxb7 Rc5 28.Rxa7 Rxc2 29.Rb7 Rc1+ 30.Kf2 Ke5 31.Rb3 Rc2+ 32.Kf3 d5 33.Re3+ Kf5 34.Re2 Rc4 35.g3 h5 36.b3 Rc5 37.Ke3 Rc3+ 38.Kd4 Rf3 39.Kxd5 Kg4 40.b4 h4 41.gxh4 Kxh4 42.b5 Rd3+ 43.Kc4 Rd7 44.b6 Rb7 45.Kc5 Rxb6 46.Kxb6 Black resigned, perrypawnpusher - islanderchess, blitz FICS, 2008
It is probably useful for both Black and White to know that Rybka's recommended move is: 8...Bf8, which keeps Black's advantage.
In part this is because if White then takes the Rook with 9.Qxh8, Black traps it with (of course) 9...Bg7. If White wriggles with 10.Qh7, Black has the simple 10...Nf6. Either way, White will wind up with only a Rook and a couple of pawns for his Queen – not to mention a vanished attack.
analysis diagram
White does best after 8...Bf8, instead of capturing the Rook on h8, to retreat his Queen to Qg3 and then develop his "Jerome pawns" and pieces as in a regular Jerome Gambit game.
9.Qxh8
What difference does having the Bishop on e7 instead of f8 make? Can't black play the similar 9...Bf6?
Yes, he can, but after 10.Qh7+ Bg7 White's situation is different, because Black has taken 4 moves to get his piece to g7, instead of 3 moves in the case of 8...Bf8.
analysis diagram
As a result, Black's Knight is still at home on g8, and White can use his extra tempo to play 11.e5.
What follows then would be a back-and-forth battle to capture or free White's Queen, for example 11...d6 12.d4 Bf5 (new plan: support the Black Bishop with the Black Queen, then play ...g6-g5, discovering an attack on the White Queen) 13.Re1 Qd7 14.Na3 g5
15.e6+ Qxe6 16.Rxe6 Bxh7.
A very complicated situation!
Now, back to the game:
9...Nf6
In comparison to what we have just looked at, allowing White to exchange off his Queen produces a much simpler position, and one in which White is the exchange and two pawns ahead.
10.Qxd8 Bxd8 11.Nc3 d6 12.d3 Be6
I think I have a win, but it will take time.
13.Bxh6 Ng4 14.Bf4 Bh4 15.h3 Nf6 16.g3 Nh5 17.Be3 Bf6 18.g4 Ng7 19.f4 Rh8
Both of us have made progress. The two Bishops will help Black in defending.
20.Kg2 Bh4 21.f5 gxf5 22.exf5 Bd7
23.Bf2 Bc6+ 24.Ne4 d5 25.Ng3 Bg5 26.Rae1 Bd2 27.Re2 Bg5
28.Bd4 Rh7 29.Bxg7 Kxg7 30.Nh5+ Kf7 31.Kg3 Bd7
Slowly White's pawns creep up the board as the Rooks threaten invasion.
32.Rfe1 Kg8 33.h4 Bd8 34.d4
Locking up the light-squared Black Bishop, but there was a better move – which I played next.
34...c6
It was necessary for Black to play 34...Kf8 and keep the Rook out.
35.Re8+ Bxe8 36.Rxe8+ Kf7 37.Rxd8 b5
Resistance is futile.
38.Rd7+ Kg8 39.Rxh7 Kxh7 40.g5 b4 41.Kf4 a5
42.Nf6+ Kg7 43.h5 Kf7 44.h6 Ke7 45.h7 Kf7 46.h8Q

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+
6...Ke6 7.Qf5+ Kd6 8.d3
This is an unusual alternative to the more frequently played 8.f4. Clearly White avoids the complexities associated with that move – 8...Qh4+ 9.g3 Nf3+, for starters – while preparing to put pressure on the Knight at e5 with Bc1-f4. On the other hand, he battles along lines where White remains two pieces down.
8...Nh6
Black, in turn, takes immediate aim at the White Queen.
Two alternatives have been seen: 8...Qf6 9.Be3 Bxe3 10.fxe3 Ke7 11.d4 Nc4 12.Qc5+ Nd6 13.e5 Qh4+ 14.g3 Qe4 15.exd6+ Ke6 16.Qe5+ Qxe5 17.dxe5 cxd6 18.exd6 Kxd6 19.Nc3 Nf6 20.Nb5+ Ke7 21.0-0-0 b6 22.Rd4 Bb7 23.Rhd1 Bc6 24.Nc7 Rac8 25.Na6 Rhe8 26.Nb4 Kf8 27.Kd2 Re4 28.Re1 Rxd4+ 29.exd4 Re8 30.Rg1 Bb5 31.b3 Ne4+ 32.Kc1 Nc3 33.Kb2 Ne2 34.c4 Bc6 35.Rd1 Be4 36.d5 Kg8 37.Rd2 Ng1 38.Na6 Nf3 39.Rf2 Ne5 40.Kc3 Ng4 41.Rd2 Rf8 42.Rd4 Rf3+ 43.Kb4 Nf6 44.a4 Bc2 45.Nc5 bxc5+ 46.Kxc5 Ne4+ 47.Rxe4 Bxe4 48.b4 Rf6 49.a5 Kf8 50.Kd4 Bc2 51.b5 Ke7 52.c5 d6 53.c6 Kd8 54.b6 axb6 55.axb6 Bb3 56.Ke4 g6 57.h4 Rf5 White resigned, dott - dj-travis, GameKnot.com, 2004;

9.Bxh6 gxh6
Rybka's assessment is that things have already entered the Twilight Zone, suggesting instead: 9...Rf8 10.Bg5 Rxf5 11.Bxd8 Rxf2 with a clear advantage to Black.
10.Nc3
Here 10.f4 would have led to the recover of a piece as well.
10...Rf8 11.Nb5+ Kc6 12.Qxe5 d6
Capturing the White Knight with the King would have only led to an exchange of pieces (12...Kxb5 13.a4+ followed by 14.Qxc5), so Black protects his Bishop first.
He had sharper play in 12...Bxf2+ 13.Ke2 d5 14.a4 Bg4+ 15.Kd2 Qg5+ 16.Qxg5 hxg5 17.exd5+ Kb6 but it can be difficult to think of "attack" when your King needs "defense."
analysis diagram
13.Nd4+
Rybka points out the sneaky alternative 13.Qd5+, as 13...Kxb5 leads to checkmate, while 13...Kb6 and 13...Kd7 allow 14.d4.
The position has become complicated for both players, a situation that favors the one more familiar and comfortable with this kind of play.
13...Bxd4 14.Qd5+ Kd7 15.Qxd4
15...Qf6 16.Qxf6 Rxf6 17.f3
Black has managed to remove the immediate danger to his King, and he has the standard small advantage of a piece for two pawns, but this kind of position is like one's own back yard to a Jerome Gambit player.
17...b6 18.Rf1 Bb7 19.Kd2 Rg8 20.g3 Kc8
21.f4 Rf7 22.f5 Rg5 23.Rae1 Rh5
Black has underestimated or overlooked his opponent's reply.
24.h4 Rg7 25.Rf3
25...d5
This only unleashes the "Jerome pawns".
26.f6 Rf7 27.e5 d4 28.e6 Rf8 29.e7 Rh8
30.Rf4
Finally, Black catches a small break. White does not really need to worry about saving his Rook: after 30.f7 Bxf3 he can play 31.f8/Q+ Kb7 32.Qxf3+ Ka6 33.Qxh5 and be a Queen ahead, with another pawn ready to promote!
30...Bd5 31.f7 Bxf7 32.Rxf7 Re8
Perhaps Black even chuckled here, and reminded himself of the old saying All Rook and pawn endings are drawn.
33.Re4 c5 34.Rf8 Kd7 35.Rf7
At this point, this Rook and pawn ending does look drawn.
But looks can be deceiving.
35...a5 36.a4 b5 37.axb5 Rd5 38.Rxh7 Rd6
White's pawns are beginning to look like ants at a picnic.
39.c3 dxc3+ 40.Kxc3 Re6

47.Kxc5 Kd7 48.Kd5 Rxe7 49.Rxe7+ Kxe7
Black keeps capturing pawns, and his position keeps getting worse.
