In the following game my opponent out-played me, encouraging me to extend a shell of "Jerome pawns" which he then cracked like an egg. I'd like to look at a couple of interesting positions from the game, neither of which I "solved" correctly.
perrypawnpusher - mconst
blitz, FICS, 2010
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6
7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Ne5
This is the first position. Black is clearly being provocative, asking for the d-pawn or the f-pawn to kick the Knight to g4. I've not seen it before.
Instead, I've seen 9...Nf6 in perrypawnpusher - hogmaster, JG3 thematic, ChessWorld, 2008 (1-0, 37); perrypawnpusher - joejox, blitz, FICS, 2009 (1/2- 1/2, 27); perrypawnpusher - DysonLin, blitz, FICS, 2009 (1-0, 23); perrypawnpusher - Mences, blitz, FICS, 2009 (1-0, 38); perrypawnpusher - andrecoenen, blitz, FICS, 2010 (1-0, 25); perrypawnpusher - SkypeFro, blitz, FICS 2010 (1-0, 39); perrypawnpusher - BishopChris, blitz, FICS, 2010 (1-0, 22);
I've also faced 9...Be6 in perrypawnpusher - jamtaylo, blitz, ChessWorld Welcome JG, 2009 (1-0, 27).
10.0-0 Nf6 11.f4
Likely better is 11.d4, which would cause me to re-think my understanding of how to play this position. The attraction of the move is obvious: kicking the Knight on e5 and opening the c1-h6 diagonal for White's dark squared Bishop. It also means that White should then answer 11...Neg4 (not the best response) with 12.Qd3, giving up, at least for the moment, the idea of pinning Black's Knight along the f-file with either the Rook or Queen and then attacking it with e4-e5.
11...Neg4
This is probably not as solid as 11...Nc6 but it is much more annoying.
12.Qf3 Nh6
13.h3 Kf7 14.e5 Ne8 15.g4 Rf8 16.Qd5+ Be6 17.Qxb7 Qh4
Here's the second position of interest. The question is: Is Black bluffing?
He had the choice of the ordinary 17...dxe5 18.fxe5+ Kg8 19.Rxf8+ Kxf8 20.Qe4 Nf7 which is about equal.
Instead, he offers a Rook.
18.Qg2
I played this too quickly, but it is worth looking at 18.Qxa8 d5, locking the Queen out. The alternatives to the pawn move, 18...Qxh3, 18...Nf6 and 18...Nxg4, are all well met by 19.Qg2.
When White then covers his h-pawn with 19.Kg2, Black has 19...Nd6, exposing an attack on the Queen.
As Her Majesty runs back home, Black breaks through: 20.Qxa7 Ne4 21.Qa3, however I have not been able to find anything better for Black than either 21...Bxg4 or 21...Nxg4 each which yield nothing more than a draw through perpetual check after 22.hxg4.
18...Rb8 19.f5 Bc8 20.d4 Bb7
The game is complicated, and my play from here on out is not good.
21.Qh2
White needed to shield himself from that Bishop with 21.d5 dxe5 22.c4, when Black might have a slight edge.
21...Kg8
Prudent, but there were good attacking chances with 21...Nxg4.
22.Nd2
White needed to get rid of that Knight with 22.Bxh6
22...Nxf5
Even more deadly was 22...Nxg4, but my game was collapsing fast.
23.gxf5 Qxd4+ 24.Rf2 Rxf5 25.Nb3 Qd1+ White resigned
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ ...and related lines

Cutting It Close
I usually play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) with attacking play in mind, but sometimes I switch to trying to squeeze out a win from a pawn-up game – which surely must frustrate my chess pieces...
perrypawnpusher - jonathankochems
blitz 2 12, FICS, 2010
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6
A game we played earlier this year continued: 6...Kf8 7.Qxe5 Qe7 8.Qf4+ Nf6 9.Nc3 d6 10.0-0 Kf7 11.d3 Rf8 12.Nd5 Qe5 13.Nxc7 Qxf4 14.Bxf4 Rb8 15.Nd5 Nxd5 16.exd5 Bf5 17.Rae1 Bb4 18.Re2 Rbc8 19.a3 Bc5 20.b4 Bd4 21.Bxd6 Rfe8 22.Rfe1 Bc3 23.Rxe8 Rxe8 24.Rxe8 Kxe8 25.Bc5 a6 26.Kf1 Bb2 27.a4 Bd7 28.a5 Ba4 29.c4 Bc2 30.Ke2 Bc3 31.Ke3 Kd7 32.Ke4 Be1 33.f4 Bc3 34.Bd4 Bxb4 35.Bb6 Kd6 36.f5 Bc3 37.g4 Bf6 38.Ke3 Ke5 39.Bc7 checkmate, perrypawnpusher - jonathankochems, blitz FICS, 2010
7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Be6
10.f4
Playing 10.0-0 was more accurate. I almost never get this right.
10...Bf7
This leads to about an equal game. Black could have stirred up more mischief with 10...Qh4+ 11.g3 Qh3.
Alternatively: 10...N6e7 11.f5:
11.0-0 d5 (11...Nf6 12.f5 Bf7 13.b3 Nc6 14.Bb2 Ke7 15.d4 Re8 16.e5 dxe5 17.dxe5 Nd5 18.Qc5+ Kd7 19.e6+ Bxe6 20.fxe6+ Kxe6 21.Nc3 Nxc3 22.Bxc3 Qh4 23.Qf5+ Ke7 24.Rfe1+ Kd6 25.Rad1+ Nd4 26.Bb4+ Kc6 27.Qc5+ Kd7 28.Rxd4+ Black resigned, Hiarcs 8 - RevvedUp, 2006) 12.d3 dxe4 13.dxe4 Nf6 14.Nc3 Ng4 15.Qd3 Qxd3 16.cxd3 Rd8 17.Rd1 c5 18.h3 Nf6 19.Be3 b6 20.g4 Nc6 21.Rac1 Ke7 22.a3 Bb3 23.Rd2 Rhf8 24.Kf2 Rd7 25.e5 Nxe5 26.fxe5 Ne4+ 27.Ke2 Ng3+ 28.Ke1 Rf1 checkmate, RevvedUp - Hiarcs, 2006; and

11...Nf6 12.f5 Ne5 13.d4 Ned7
The retreat to c6 was probably stronger.
14.e5 dxe5 15.dxe5 Nd5 16.Qa3+ Qe7 17.e6 Qxa3 18.Nxa3 Bxe6
19.fxe6+ N7f6 20.Bg5 Ke7 21.Rae1 Rae8
This Queenless middle game or piece-full endgame is slightly in White's favor. It is not the kind of position that gambiteers always aim for, but it is a rather healthy state for one who plays the Jerome Gambit.
22.c3 a6 23.Nc2 c5 24.b3
24...Kd6 25.Bxf6
I should have played 25.c4 first, chasing one of the protectors of the f6 Knight.
25...Nxf6 26.Rf5
This looks awkward.
After the game Rybka recommended 26.Ne3 Rxe6 27.Nf5+ Kd7 28.Rd1+ Kc8 29.Nxg7, but the resulting position has a similar problem: it is going to take White a lot of work to make his extra pawn pay off.
26...b6 27.Rfe5 Re7 28.Na3 b5 29.c4 b4 30.Nc2 Rhe8
Black's well-placed King makes White's extra pawn almost meaningless.
31.Rg5 g6 32.Ree5
Cute – but wrong. Now 32...h6 wins the exchange and then a pawn for Black.
32...Rxe6 33.Rxc5 Ne4
This looks like a winning move, and my opponent played it as if it were.
Best play, however, as Rybka showed after the game, was more complicated: 33...Re2 34.Nxb4 Re1+ 35.Kf2 Ne4+ (the right time to check with the Knight) 36.Kf3 Rf8+ (or 36...Nxg5 37.Rxg5)37.Kg4 Nxc5 38.Rd5+ Ke6 39.Rxc5 Re2 40.Kg3 Rff2 41.h3 Rxg2+ 42.Kf3 Rh2 43.Ra5 Kf6 44.Rxa6+ Kg5. White has two pawns for the exchange, and the game is in balance.
analysis diagram
34.Rcd5+
White would pick up another pawn if he checked with the other Rook: 34.Rgd5+ Ke7 35.Rc7+ Kf6 36.Rxh7
34...Kc6
This allows a fork at d4 which would be good for White. Black's best was another exchange-for-Knight-and-pawns ending with 34...Kc7 35.Nxb4 Nxg5 36.Rxg5 Rd8
35.Rg4 Nc3 36.Nd4+

Sole Survivor
Although my involvement in a Chessworld welcoming Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Thematic Tournament was quickly reduced to one game, (see "Busy!" and "*Poof!*"), it turned out to be an interesting one, worth sharing.

After this, the Bishop is on the sidelines. It probably should have returned to f7 with about an equal game.

The "Jerome Gambit pawns" are beginning to assert themselves.
19...dxe5
Too cooperative. Rybka 3 recommends: 19...h4 20.Qf2 Nd7 21.e6 Nf6 22.Bg5 Ne7 23.Bxh4 Qe8 24.Bxf6 gxf6 25.Ne4 Qh5 26.Nxf6 Qxf5 27.Qxf5 Nxf5 28.Nd5 c6 29.Nc7 Ke7 30.Nxa8 Rxa8 31.Rd2 d5 32.Re1 Rh8 which is about even.

* Poof! *
Remember the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Thematic Tournament that I mentioned a few posts ago (see "Busy!") – the one that I had joined, a 10-player double-round robin?
Turns out almost nobody was interested in playing the Jerome Gambit – only 3 games out of 81 went that way. My hat off to leif41no and Namecheck for playing a couple of Jerome-ish games with each other (actually, the games started 1.e4 e5 2.Nf3 Nf6 3.Bc4 Bc5 4.Bxf7+). I will let you know how they do.
In the meantime, I have one Jerome against jamtaylo. Since I don't plan on contesting the non-Jerome Gambit games, and will lose them by forfeit, that raises an interesting question: am I being unfair to jamtaylo?
