I have seen [GM Larry] Christiansen venture your favorite Jerome Gambit in ICC blitz or simul games, but I'm not sure he really believes in it.
You can imagine my response! Grandmaster Larry "Storming the Barracades" Christiansen!? The Jerome Gambit??
As politely and calmly as possible (under the circumstances), I asked to see some of the games...
I began searching for LarryC games but ran into the dreaded "Game Database temporarily unavailable." But I turned up a couple before that kept happening...
I think he mostly does this as an interesting way to spot a weaker opponent a piece in online simuls.
Remembering now, he probably does it mostly via the C24 Bishop's Opening, which is how I stumbled upon the LarryC Jerome Gambit phenomenon -- while searching for Urusov Games, of course.
I will try to dig up some more this weekend, but anyone you know on ICC can find them with the search string "Search LarryC C24 White" etc.
I suggested that he look for Jerome Gambit games under C50 as well. I heard back from Dr. Goeller.
I spent some more time looking for LarryC games on ICC with the Bxf7 sac but couldn't find any more. I am not sure why, because I am certain I saw a bunch of them a couple years back while doing a search. It's possible that unrated games (such as simul games) are only temporarily available on the server and then vanish, even if played by LarryC.
In any case, there are very few C50 games at all, and none that really meet your criteria. And I only found the one C24 game I sent. It seems almost certain I saw them while searching through recent C24 games, which I do from time to time. It seems unlikely I was looking at C50 games. Started trying C21 and got Game Database currently unavailable. But the few I was able to go through did not look promising.
So sorry to get your hopes up and then disappoint... But at least you have one game. I'll keep an eye out for more.
In all, Dr. Goeller sent me two games, which we will look at in future posts.
I like analyzing old and obscure lines as much as you do, but I try to confine myself to strategically sound openings that are based on some principle (even if that principle is just speedy development). Almost always, the lines I look at have been played by GMs or other strong players, who obviously agreed there was something to it...
I took a quick look with Fritz -- see results below. I do not think it's something I'd try myself as White. And I think I'm prepared now to face it as Black.... :-)
1.e4 e5 2.Bc4 Bc5 3.Nc3 Nf6 4.Nd5
4...Nxe4!?
Remember: as Tim McGrew shows [see McGrew's two "Gambit Cartel" columns from ChessCafe.com on the Blackburne Shilling Gambit: 1 &2], this move is better than its reputation in the regular Blackburne Shilling Gambit, so long as you are willing to sac a piece for Cochrane Gambit type play. [Readers interested in 1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nxf7!? should check out Dr. Goeller's work on the Cochrane at his Kenilworthian site] Here it may even be better because of Bc4 for White, which sets up some nice shots with c6 and d5 coming.
Black has a number of perfectly good alternatives, of course:
b) 4...0-0 5.b4 (5.d4?! exd4 6.Bg5 Be7 =/+) 5...Bb6 6.d3 Nxd5 7.exd5 e4!? with the idea of Qf6;
c) 4...c6 5.Nxf6+ Qxf6 6.Nf3 d6=
5.d4!
Probably best.
5.Qg4 Bxf2+ 6.Kf1 0-0! ["This is certainly a lot more fun than most of the lines" - Tim McGrew, on the related line in the regular BSG ]7.Qxe4 Bxg1 8.Rxg1 c6 9.Bd3 (9.Ne3 d5 10.Nxd5 cxd5 11.Bxd5 Nd7 -/+) 9...f5 10.Qxe5 d6 11.Qd4 cxd5 12.Qxd5+ Kh8 =/+ and I think you have to prefer Black slightly here, though I admit it is about equal and probably playable for White.
5...Bxd4 6.Qg4 c6!
6...0-0?! 7.Bh6±.
7.Qxg7
7.Qxe4 Qa5+ 8.Bd2 cxd5 9.Bxd5 Qb6 unclear

9.Qxh7!? Qa5+ -/+
9...Kxd8 10.Bxd5 Nxf2 11.Nf3 Nxh1=
Interesting enough, all by itself – but things were about to get even more interesting... (to be continued)
I was playing my way through some of Bill Wall's chess games when I suddenly felt like Alice must have felt, after moving through the Looking Glass. What I found on the other side was not quite a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and I wasn't sure quite what to call it.
Wall,B - Danyum Chess.com, 2010
1.e4 e5 2.Nf3 Nf6
So far, we have a Petroff Defense.
3.Bc4 Bc5
Okay, maybe this is a symmetrical Bishop's Opening.
4.Nc3
A Vienna Game? A Russian Three Knights Game headed toward an Italian Four Knights Game?
4...Ng4
And what is that? A Jabberwocky?
5.Bxf7+ Kxf7 6.Nxe5+ Nxe5 7.Qh5+
This looks remarkably like a Jerome Gambit, only Black has a Knight at b8, not g8; and White has a Knight already on c3.
7...Ke6
Or, as in the only other example that I have been able to find of this line: 7...g6 8.Qxe5 d6 9.Qf4+ Ke8 10.0-0 Rf8 11.Qh6 Bxf2+ 12.Rxf2 Rxf2 13.Kxf2 Qf6+ 14.Kg1 Nd7 15.Qxh7 Nf8 16.Qxc7 Ne6 17.Qxd6 Qg5 18.d4 Qg4 19.Bd2 Ng5 20.Qe5+ Kf7 21.Bxg5 Qh5 22.Qf6+ Ke8 23.Qe7 checkmate Jeng, - Hatcher, San Jose, 1994.
8.d4 Bxd4
9.Nb5 Nbc6
A reasonable move, but one that loses. Rybka recommends: 9...Bxf2+ (the Bishop is lost, anyhow) 10.Kxf2 d6 (so that Black will have a counter to White's Bishop's attack on his Queen) 11.Bg5 g6 12.Qh3+ Kf7 13.Qb3+ Be6 14.Bxd8 Bxb3 15.axb3 Rxd8 16.Nxc7 Nbd7 17.Nxa8 Rxa8 when Black will have two Knights against a Rook and a pawn; and probably an edge.
In 1877 in Australia, H. Charlick played a correspondence game combining the Evans Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4) with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+): see "The Evans Jerome Gambit". A similar idea has appeared in the Bishop's Opening, 1.e4 e5 2.Bc4 Bc5.
Delanoy - KameneckiCannes, France (2), 2000 1.e4 e5 2.Bc4 Bc5 3.b4 According to Bishop's Opening expert Michael Goeller,
This move is a good method of transposing to the Evans Gambit since it allows for some independent possibilities, some of which are quite favorable for White. If you like to play the Evans Gambit, this seems the most flexible way to do so..
3...Bxb4
Accepting the gambit by 3....Bxb4 challenges White to prove compensation. The resulting positions are very similar to the Evans Gambit and White probably does best to transpose to the Evans in most lines. There is one significant advantage for White, however, in offering the gambit pawn before developing the Knight to f3. In the line 4.c3 Ba5, which has proven one of the more thorny in Evans Gambit theory, White can play 5.f4!? instead of 4.Nf3 Nc6. - Goeller
4.c3
Instead, 4.f4 exf4 is the McDonnell Double Gambit, about which there is an interesting article by IM Nikolai Minev. 5.Nf3 Ne7 6.Ng5 Ng6 7.Qh5 Qf6 8.c3 h6 9.Bxf7+ Ke7 10.Bxg6 Qxg5 11.Qxg5+ hxg5 12.cxb4 d6 13.Nc3 c6 14.d4 Kf6 15.Bf5 Bxf5 16.exf5 Kxf5 17.0-0 Kg6 18.g3 fxg3 19.hxg3 d5 20.Bd2 Nd7 21.Rae1 Rh3 22.Kg2 g4 23.Ne2 Rhh8 24.Nf4+ Kh7 25.Re7 Nf6 26.Ne6 Nh5 27.Rff7 Rhe8 28.Nf4 Nxf4+ 29.gxf4 Rxe7 30.Rxe7 a5 31.a3 axb4 32.Bxb4 b5 33.Kg3 Kg6 34.Kxg4 Black resigned, was Brownson - Jerome, Iowa 1875.
From here on, White consistently outplays Black in an interesting Queenless middlegame, and an instructive endgame. 14.Be3 a6 15.0-0 Kg7 16.Rac1 h6 17.Rfd1 Ne7 18.h3 c6
White has more space and better development, while Black plans his defensive formation.
5.d4 exd4 6.Bxf7+ Kxf7 
White has more space and better development, while Black plans his defensive formation.
By allowing Black to double his pawns on the e-file, White has found time to put a serious cramp into his opponent's game.
Finally!
