The other day I got in a couple of blitz Jerome Gambits (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) at FICS (Free Internet Chess Server). The first game I shared with readers yesterday (see"Diagnosis: Misplaced Knight"). The second one, well, er, um... I guess I can say that there's "winning ugly" and "losing ugly," and it's better to win ugly...
perrypawnpusher - Lark
blitz 2 12, FICS, 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

It turned out that this game was the third time that I'd played the Jerome Gambit against Lark. Our first game continued: 5...Kf8 6.Nxc6 dxc6 7.0-0 Bd6 8.f4 g6 9.d4 Bd7 10.Nc3 Nh6 11.f5 Qh4 12.e5 Nxf5 13.exd6 cxd6 14.g4 Re8 15.gxf5 Bxf5 16.Qf3 Qxd4+ 17.Kh1 Kg7 18.Qf2 Black forfeited on time, perrypawnpusher - Lark, FICS, 2009

Louis Morin of the Jerome Gambit Gemeinde was the "guest" playing White in the two aforementioned games.
11.f4 d6 12.f5 Ne5 13.d4 Nc4 14.Qg3
14...Rf7 15.Nc3 Kf8 16.Bg5
I spent way too much time trying to figure out if 16.f6 worked here. It does – but I didn't play it. The line is complicated, but leads to White's advantage: 16.f6 gxf6 (not 16...Rxf6 17.Bg5 Ng6 18.Nd5 winning) 17.Bh6+ Ke8 18.Nd5 f5 19.Rae1 Kd7 20.Qb3 Nxd5 21.Qxc4 Bb7 22.exd5 a6.
16...h6 17.Bc1
It looks like 17.f6 was playable, too.
17...Bb7 18.f6 Rxf6
I guess I wasn't the only player having trouble with this position. Better was 18...gxf6, although after 19.b3 Na5 20.Bxh6+ Ke8 21.Rae1 my position is beginning to look better.
19.Rxf6+
Sigh. 19.Bxh6 was the move.
19...gxf6 20.Bxh6+ Ke8 21.Qg7
Inviting another piece to the party with 21.Rf1 was stronger.
21...Kd7 22.Qg4+ Ke8 23.Qg7
Repeating the position, and considering a draw, which was silly: 23.Qh5+ Kd7 24.Qb5+ instead would have won a piece.
Now both my opponent and I seem to have been mesmerized by the clock.
23...Nd2 24.Qxf6
Or, well, just take the gift Knight at d2...
24...Bxe4 25.Nxe4
Or, well, 25.Bxd2...
25...Nxe4 26.Qh8+
At this point my nerves got the better of me (clock ticking) and I decided to swap to an endgame where I thought I had at least drawing chances. Wrong. Plus: 26.Qe6 instead was still strong.
26...Kd7 27.Qxd8+ Rxd8 28.Re1 Nf5
29.Rxe4 Nxh6 30.Rh4 Well, my intentions are clear: play the two pawns against the Knight. At my level of play there are "drawing chances" but as they say on television, "don't try this at home, folks!"
30...Nf5 31.Rh7+ Kc6 32.c3 Re8 33.Kf2
This move and next, I would have done better to start my pawns rolling with g2-g4.
33...a5 34.b3 Rf8
35.Ke2 Re8+ 36.Kd2 Ne3 37.Rg7 Nf1+ 38.Kd3 Nxh2
Not so good (for me).
39.g4 Nf3 40.g5 Nh4 41.c4 Nf5 42.d5+ Kb7 43.Rh7 Re7 44.Rxe7 Nxe7
Things are going just as I planned – except that Black still has a won game. Lucky for me, neither one of us seemed to notice.
45.Ke4 Ng6
The win for Black comes after he busts up White's Queenside pawns and then infiltrates with his King: 45...b5 46.cxb5 Kb6 47.Kd4 Kxb5
46.Kf5 Nh4+ 47.Kf6
White has a draw here either playing tag with the Black Knight – 47.Kg4 Ng6 48.Kf5 Nh4+ 49.Kg4, etc. – repeating the position; or by advancing toward the enemy pawns with 47.Ke6, so that the ...b5 break is not good enough to win.
The text is "playing for the loss".
47...Kc8
Of course 47...b5 wins.
48.g6 Nxg6 49.Kxg6 Kd7 50.Kf6
The position is drawn. White's King cannot make progress toward attacking Black's pawn base at c7 (as long as the Black King is dilligent), and if he is foolish enough to try entry through a3, a4 and b5, Black's King will follow him and pick off the White pawns.
50...c6
Dear Readers, let this be a lesson to you: eat your vegetables, get daily exercise – and study your chess endings!
51.Kf7 cxd5 52.cxd5 b5 53.a3 Kc7 54.Ke7 b4 55.a4

Diagnosis: Misplaced Knight
It has been said that if one piece sits poorly in a chess game, the entire position becomes poor for that player.
I think that remark usually refers to games played above the level of those involving the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), but it does appear true that in the following game, my opponent's Queen Knight (and to some extent, his King Knight) caused him a lot of difficulty.
Of course, I was cooperative: as Genrikh Chepukaitis said “You need not play well - just help your opponent to play badly”

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian.
4.0-0 Bc5 5.Bxf7+ Transposing to a Jerome Gambit, of course. I think the extra 0-0 helps White more than the extra ...h6 helps Black.
5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ng6
8.Qd5+
I continue to prefer Alonzo Wheeler Jerome's "nudge" here, instead of the direct capture of the Bishop.

Fritz8 prefers 13...Nh5 14.Qd3 Ngf6 15.f4, giving White a small advantage.

Black needed to complicate things with something like 14...Nh5, for example 15.Qf3 (eye on the Knights!) Rf8 16.Qe2 (the same) Ngf6 17.e5 Kf7 (castling-by-hand!) 18.exf6 Nxf6 19.Re1 Qd7 20.Ne4 Kg8 and White is a pawn up, but things are still challenging: if 21.Nxd6 then 21...Bxh3.
15.Re1 Qd7 16.hxg4
16...Nxg4 17.f3 Nf6 18.e5 Nh5
A bit better was 19.Qh4 Qf7 20.exd6+ Kf8 21.Re7 Qg6 22.d5, snaring the Black Bishop; but the text is sufficient.
19...Kf7 20.Qh2 g6 21.Re7+ Black resigned

Not Quite the Jerome Gambit - Addendum
Readers of yesterday's post "Not Quite the Jerome Gambit" may have noticed that the line played by leif41no and Namecheck – 1.e4 e5 2.Nf3 Nf6 3.Bc4 Bc5 – did not have to be Jerome-ized at all with 4.Bxf7+. Instead, White had at his disposal 4.d4, which, after 4...exd4 would transpose to The Urusov Gambit – very well covered by Michael Goeller at his website (check links: Kenilworthian).

Not Quite the Jerome Gambit
As mentionied in the earlier posts "Busy!" and "*Poof!*", I almost had a chance to play in another Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Thematic Tournament, but wound up, instead, getting in only one Jerome Gambit game – see "Sole Survivor".
Two other players in the tourney gave it a go, with some feelings of uncertainty, except that what they played was not quite the Jerome Gambit.

The players swapped notes as the game started:

Here we already have an unusual position, coming out of the Petroff Defense – 1.e4 e5 2.Nf3 Nf6 3.Bc4!? Bc5?! – or the Bishop's Opening – 1.e4 e5 2.Bc4 Nf6 3.Nf3!? Bc5?!

Harried
The (in)famous historical Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, Amateur - Blackburne, London 1885 featured a harried White Queen that captured one Rook on a diagonal and another by sliding across a rank – only to watch her King be checkmated across the board.
The following game, from the current Chessworld Jerome Gambit Thematic Tournament, features two of the top players and highlights a harried Black Queen shuttling forward and back, until her own demise.

5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6
White reaches an interesting position, historically. Here "Amateur" played 8.Qxh8 and after 8...Qh4 9.0-0 Nf6 10.c3 he was crushed by Blackburne: 10...Ng4 11.h3 Bxf2+ 12.Kh1 Bf5 13.Qxa8 Qxh3+ 14.gxh3 Bxe4 checkmate.
At that time, 10.Qd8 was suggested by J.B. and E.M. Munoz, giving White the better game; although, almost 120 years later, Chandler and Dimitrov showed that Black could hold the draw.
Throughout this tournament stampyshortlegs has shown a good understanding of the Jerome Gambit. Will he "fall into" and become a victim of Blackburne's "trap" – will he grab the Rook and ask his Queen to fight her way out, "risking" a draw in the process – or has he come up with an improvement, himself?

White has three pawns for his piece, but with Black's King not under attack, and with White's pieces not developed, the position has to be judged better for the second player.

More Tactics
For those who believe that chess is "99% tactics", and this is especially true for those who play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), very often one lives by the tactic, and dies by the tactic...
In this position, seeing that he was losing his Queen for a Rook, White resigned.
Instead, he could have tried 33.Nb5 Qxb2+ 34.Rxb2 Rxb7 35.Kxc4 a6 36.a4 axb5+ 37.axb5 with at least equal chances.

Here are three more examples (a bit more challenging) from the current Chessworld Jerome Gambit Thematic tournament.
DREWBEAR 63 - GladtoMateYou
JGTourney4 ChessWorld, 2009
Despite being the extra piece up that the Jerome Gambit defender often receives, Black finds that his King has wandered into a mating net. If he keeps his wits about him, though, he can still split the point.
Black had to try 30...Nxc4 31.Kxc4 Bd5+ 32.Rxd5 cxd5+ 33.Kxd5 Rxg7 when White, down the exchange, does best to force a draw by repetition: 34.Ra3+ Kxb5 35.Nd4+ Kb4 36.Nc2+ Kb5 37.Nd4+ draw

30...Ka4 31.Ra3 checkmate
Black Puma - Haroldlee123
JGTourney4 ChessWorld, 2009
In this complicated position, Black holds the Jerome advantage of a piece for two pawns, but his development is a bit haphazard, and he needs to be careful. Troubling tactics lie right beneath the surface, and he should play 35...Nxg5 with a chance to settle things down a bit. Instead, he plays a very reasonable move, and receives a shock.
35...Rh8 36.g6 Kxg6 37.Nh4+ Kf6 38.Nf5 Qf7 39.Rh6+ Qg6 40.Rxg6+ Kf7 41.Rg7+ Black resigned
