All of my games in the first round of the ongoing Chess.com Italian Game tournament (see "Anybody Want A Couple of Pieces?") have been completed (without a Jerome Gambit in sight), and with 7 wins, 3 draws and 2 losses, I have to wait to see how many of my erstwhile opponents - I am thinking of LVercotti (currently 8 wins and 1 draw), mikerj (currently 6 wins, 1 draw and 2 losses) and FedorMarkov (currently 6 wins, 1 draw and 2 losses ) in particular - catch or pass me. I think three players advance to the next round, so I have my chances...
In the meantime, in the third round of the earlier Chess.com Italian Game tournament, (see "Anybody want a (couple of) piece(s) of me?") I managed a successful Jerome Gambit (see "Do I Share Everything? No.") but I do not think that I will be advancing to the next round, as that may be my only win. Que sera sera.

Philidor1792 - jenskun
Russia Central Federal District vs Phil,
1.e4 e5 2. Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7
5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke7
Infrequently played, but not bad.
The experimental 8.Qg5+ was tried in Wall,B - CKFM, FICS, 2012 (1-0, 44).
8... d6 9. Qe3
The Database has three games with 9.Qg5+: fehim - Schiele, FICS, 2006, (0-1, 59); stampyshortlegs - calchess10, JGTourney4, ChessWorld 2009 (1-0, 31); and Wall,B - Vassilev,R, Chess.com, 2010 (1-0, 32).
Instead, 9... Nf6 was seen in three MrJoker games: MrJoker - Yuvi, ICC, 2011 (1-0, 16); MrJoker - Cleanbishop, ICC, 2012 (1-0, 46); and MrJoker - taz, ICC, 2013 (1-0, 43).
The Bishop move seems to invite f2-f4 by White, gaining a tempo.
10.O-O Nf6 11.f4 Bf7 12.f5 Ne5 13.d4 Nc6 14.e5 dxe5 15.dxe5 Nd5 16.Qg3 Kf8
The extra tempo for White, the "Jerome pawns" and Black's uneasy King have lead to an equal game. As we have frequently seen in Jerome Gambit lore, when White has equalized, he has the advantage.
17.Bg5 Qc8 18.e6 Bh5 19.Nc3 Nxc3 20.Qxc3 Rg8 21.f6 gxf6 22.Qxf6+ Ke8 23.Rad1 Qd8 24.Rxd8+ Rxd8 25.b4 b5 26.a4 a6 27.axb5 Black resigned

But I haven't shared everything.
Here is an example from last year, drawn from the post "Jerome pawns -Clowning Around" where I was discussing preparations for my first-round game against djdave28 in the current Chess.com Italian Game tournament
After my discouraging loss with the Jerome Gambit in my previous Chess.comItalian Game tournament (perrypawnpusher - Buddy_Thompson), I knew that I had to cook up something new, or risk facing a future opponent who just "looked the refutation up" (and not even on this blog, mind you, but in my recent games on Chess.com).
I was happy that I did do the research, too, because in my third Jerome Gambit in my current tourney, my opponent went straight for the same line (leaving out the superfluous Queen check).
I won that encounter, and two rounds later I found myself facing the same opponent. Would he repeat the line - even though I had been victorious? Of course he would!
perrypawnpusher - djdave28
Italian Game tournament, Round 3
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+
Here is a relevant computer game: 7.f4 Qf6 8.Qxe5+ Qxe5 9.fxe5 Kxe5 10.b4 Bd4 11.c3 Bb6 12.d3 d5 13.Rf1 dxe4 14.Bf4+ Ke6 15.dxe4 Nf6 16.Nd2 Bd7 17.a4 a5 18.b5 Rhf8 19.O-O-O Rac8 20.h4 Bc5 21.Nb3 Bb6 22.c4 Nh5 23.g3 Nxf4 24.Rxf4 Ke7 25.Rxf8 Rxf8 26.Rd3 c5 27.e5 Rf1+ 28.Kb2 Re1 29.Rd6 Bc7 30.Nxc5 Bc8 31.Rd5 Rxe5 32.h5 b6 33.Na6 Rxd5 34.Nxc7 Rxh5 35.Nd5+ Kd6 36.Nxb6 Be6 37.Kc3 Kc5 38.Na8 Rh3 39.Nc7 Rxg3+ 40.Kd2 Bxc4 41.Na6+ Kd6 42.Nb8 Ra3 43.Nc6 Rxa4 44.Nd4 Kc5 45.Nf3 Kd5 46.b6 Ra3 47.Nh4 Ke4 48.b7 Rb3 49.Ng2 Rxb7 50.Ne3 Bd3 51.Nd1 Kd4 52.Ke1 a4 53.Kf2 a3 54.Kg3 Be2 White resigned, Matacz CCT7 - Imp 0.74b, CCT7, 2005.
7...Kd6 8.f4 Qf6 9.fxe5+ Qxe5 10.Qxe5+ Kxe5 11.b4 Bd4
Previously, my opponent had backed up his Bishop, before making this strike: 11... Bb6 12.Bb2+ Bd4 (12...Kxe4? 13.Bxg7 Black resigned, axykk - bromby, FICS, 2011) 13.c3 Bb6 14.d4+ Kxe4 15.O-O Nf6 16.Nd2+ Kd3 17.Nf3 d6 18.Rad1+ Kc4 19.Nd2+ Kb5 20.a4+ Kxa4 21.c4 Kxb4 22.Rf3 Black resigned, perrypawnpusher - djdave28, Chess.com Italian Game Tournament, Round 1, 2014.
12.c3 Bb6 13.d4+ Kxe4 14.O-O
Here is another interesting computer game: 14.Nd2+ Kf5 15.O-O+ Ke6 16.a4 a5 17.b5 Nf6 18.Ba3 Re8 19.Rae1+ Kf7 20.Rxe8 Kxe8 21.Re1+ Kf7 22.Nc4 Nd5 23.Rf1+ Ke6 24.Re1+ Kf6 25.Rf1+ Kg5 26.Bc1+ Kh4 27.Rf5 Nxc3 28.

This move is the result of research into my previous game with my opponent. You won't find it in my notes to that match, however.
What does it do? Not very much. It has some stifling effect on Black's development, but it conjures up something a Bizarro Nimzovich might have commented upon: It's strong because it is so weak! It does so much by doing so little!
It actually emboldens Black's King to stay around the center of action, and return a piece for a couple of pawns.
15...a5 16.b5 Kc4 17.Na3+ Kxc3 18.Rf3+ Kxd4
19.Bb2+ Kd5+ 20.Kf1 Bd4 21.Rd1 Nf6
Black has two extra pawns, but his King looks pretty shaky.
Does White have an attack, or is he reduced to pawn-grabbing?
22.Bxd4 Ke6 23. Bxf6 gxf6 24.Re1+ Kf7 25.Rc3
This definitely looks like prospecting for pawns, and perhaps Black should let White have his way with 25...Kg6 26.Rxc7 d5. The theme of "Black's light-squared Bishop staying at home, undeveloped and blocking his Rook" would slowly be addressed by the defender.
Headed toward the "hole" at d6.
26...d5 27.Nd6+ Kg6 28.Rg3+
Suddenly the idea of invading the 7th rank suggests itself to White, along with taking advantage of the unfortunate Bishop at c8 and the pawn it defends at b7..
Another "do nothing" move. There was no way that I was going to exchange this pawn off and open lines for Black's Bishop. If my opponent's connected and passed c- and d-pawns were going to be the death of me - then, so be it.
29...Rb8 30.Re7 Bg4 31.h3 Bc8 32.Rgg7
It might seem a bit early for the second player to give up the ghost, but his position certainly is tied up.
