blackburne as Blackburne with black
In the ongoing Jerome Gambit thematic tournament at ChessWorld, player blackburn brought out J.H. Blackburne's defense, a line of some contention. One hundred and twenty four years ago, Blackburne, as Black, crushed the Jerome Gambit with fine sacrificial play. Improvements show that White can do better, and at least draw, if not win -- but the play remains complicated.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6
J.H. Blackburne's defense, returning a piece and preparing to offer a Rook as well.
7.Qxe5 d6
The start of fireworks.
8.Qxh8 Qh4 9.0-0
From here the Black Death played 9...Nf6 10.c3 (10.Qd8 was an improvement suggested in the Brooklyn Chess Chronicle 8/1885) 10...Ng4 11.h3 Bxf2+ 12.Kh1 Bf5 13.Qxa8 Qxh3+ 14.gxh3 Bxe4 checkmate, Amateur - Blackburne, London 1885

9...Qxe4
This is blackburne's updating of Blackburne. The move has been seen before, but it omits blocking in the enemy Queen, which brings about dire consequences.
10.Nc3
An alternative was 10.Qxh7+ Kf8 11.d3 Qf5 12.Qxc7 Nf6 13.d4 Be6 14.dxc5 Bc4 15.Bh6+ Ke8 16.Re1+ Ne4 17.Nc3 Qxf2+ 18.Kh1 Qf7 19.Rxe4+ Be6 20.Qxd6 Black resigned, obviously - dmyze, GameKnot, 2004
10...Qxc2 11.Qxh7+ Kf8 12.d3 Qxd3 13.Bh6+
With his Queen unlocked, DREWBEAR 63 can press a mating attack.
13...Ke8
There was no hope in 13...Nxh6, as follows 14.Qxh6+ Kg8 15.Rae1 d5 16.Re8+ Kf7 17.Rfe1 Qd4 18.Nxd5 Qxf2+ 19.Kh1 Qg1+ 20.Rxg1 Kxe8 21.Qxg6+ Kd7 22.Re1 Be3 23.Rxe3 c6 24.Re7+ Kd8 25.Qe8 checkmate
14.Rfe1+ Kd8
Drawing out the pain was 14...Be3 15.Qxg8+ Kd7 16.Rxe3 Kc6 17.Rxd3 Be6 18.Qxe6 a5 19.Qc4+ Kd7 20.Nd5 c6 21.Qg4+ Kd8 22.Bg5+ Ke8 23.Qe6+ Kf8 24.Bh6 checkmate

Wing, Center, Wing
While the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) has its refutations, if White isn't put out of his misery quickly, he can develop a very interesting game, even if "objectively" he is "worse". Play can develop all over the board, and in the resulting mayhem, anything might happpen...

JGTourney4 ChessWorld, 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.c3
One of the "modern" variations of the Jerome Gambit – including 5.0-0, 5.Nc3 and 5.d3 – where White avoids the "classical" 5.Nxe5. About 80% of the games in this tournament favored "modern" variations.
5...d5
Black decides to strike back in the center.
6.b4 Bb6
White's plan is clear: knock out the support of the pawn on e5. Black's alternate response was 6...dxe4, responding to an attack on the wing with an attack in the center.
7.b5 Nce7
Again, ...exe4 was possible.
8.Nxe5+ Ke8 9.Ba3
A Queenside Jerome Gambit attack is interesting and unusual. An indication of the fun the opening provides is that there was also a Kingside feint with 9.Qh5+ g6 10.Qf3 Be6 11.d3.
9...Nf6 10.0-0 Nxe4 11.Qf3 Nf5
Black probably needed one more piece in play to be scary, i.e. 11...Be6. Now White hits the Kingside.
12.Qh5+ g6 13.Nxg6
Here we have a complicated, dangerous, and unclear position. Fritz 8 says things will be equal after 13...Kf7 14.Nxh8+ Kg7, even though White would be up the exchange and two pawns. A few more moves give light to the computer's thinking: 15.Nf7 Qf6 16.d3 Nfg3.
analysis diagram
Messy, messy, messy – but fun!
13...Nf6 This move, instead, allows White to attack in the center: 14.Re1+ Be3 15.Rxe3+ Nxe3 16.Qe5+ Kd7 17.Nxh8 Nc4.
14.Ne5+
An oversight.
14...Nxh5 15.Re1 Bxf2+ 16.Kxf2 Qh4+ 17.Kg1 Qxe1 White resigned

Mea culpa – again
About a year ago (see "Overrated!") I played in a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) thematic tournament at ChessWorld, organized, like the one this year, by blackburne.
I had prepared a few "theoretical novelties" for my games, but one of them turned out to ge a "theoretical lemon" instead, leading to a quick loss. Worse than that, I think blackburne tried out the idea before he saw my disastrous results, and, fight as he could, he still wound up losing a point in his game, too.
I'm not sure if blackburne had a "fix" in mind for the line or not, but he recently repeated it in the current Jerome Gambit thematic tournament, and took it on the chin from eddie43.
blackburne - eddie43
JGTourney4 ChessWorld, 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
Here we go.
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6
7.Qf5+ Kd6 8.f4 Qh4+
This sharp move, the "Nibs defense," is best for Black.
9.Kd1
The "improvement" on an earlier Alonzo Wheeler Jerome game, only it allows Black to force the exchange of Queens, holding onto his two-pieces-for-two-pawns advantage – too much for White to overcome.
9...Qg4+ 10.Qxg4
Instead, 10.Ke1 Qxf5 White resigned was perrypawnpusher - drewbear, JG thematic ChessWorld, 2008.
10...Nxg4 11.e5+ Ke7
Blackburne's earlier game continued: 11...Ke6 12.Rf1 Nxh2 13.f5+ Kxe5 14.d4+ Bxd4 15.Bf4+ Kxf5 16.Bxh2+ Ke6 17.Bxc7 Bxb2 18.Re1+ Kf7 19.Be5 Bxa1 20.Bxa1 Nf6 21.Rf1 Re8 22.Nc3 Kg8 23.Nb5 Rb8 24.Nd6 Re6 25.Nf5 d5 26.g4 Re4 27.g5 Bxf5 28.gxf6 Bg4+ 29.Kd2 g6 30.f7+ Kf8 31.Rh1 h5 32.Rf1 Be6 33.Bc3 Bxf7 34.Kd3 Rbe8 35.Kd2 d4 36.Bb4+ Kg8 37.a3 Bc4 38.Rg1 Kh7 39.Rg3 Rg4 40.Rf3 Re2+ 41.Kc1 Rgg2 42.Rf7+ Bxf7 White resigned, blackburne - drewbear, JG thematic, ChessWorld 2008.
12.Ke2 b6 13.c3 Ba6+ 14.Kd1 Nf2+ 15.Kc2 Bd3+ 16.Kb3 Nxh1 17.Na3 Nf2 18.Nc2 b5 19.a4 Bc4 checkmate
Ouch.
I'd like to think that eddie43 might have gotten the idea from this blog, but he probably worked it up himself.

Beware the Bear
There are 15 players and 210 games in the tournament, but everyone is on alert: Beware the Bear!

Surprise!
If this game is any indication of the creativity that players are putting into their preparation, the tournament should provide many new insights into the Jerome Gambit!
blackburne - DREWBEAR 63
JGTourney4 ChessWorld, 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Ke6
Usual here is 5...Nxe5 or 5...Kf8.
DREWBEAR 63's move comes as quite a shock – certainly it must have been played before, perhaps in the earliest days of the Jerome Gambit; but there are no games in my database with the move, no analysis, and not even a mention of it.
Now 5...Ke6 throws the game into a whirlwind. Rybka 3 suggests that best play involves White winning Black's Queen for three pieces, and that the resulting position is about even: 6.Qg4+ Kxe5 7.d4+ Bxd4 8.Bf4+ Kf6 9.Bg5+ Kf7 10.Bxd8 Nxd8 11.Nc3 Bxc3+ 12.bxc3 Nf6.
analysis diagram
Also in need of investigation are 6.Nxc6 and 6.d4. It is not at all surprising that blackburne missed Rybka's line.
6.f4 6...Nxe5 7.fxe5
The danger mounts. Best, but not without difficulties, was 7.d4, hoping to transition into a more Jerome-like position.
7...Qh4+
8.Ke2 Qxe4+ 9.Kf1 Nh6 10.Nc3 Rf8+ White resigned
An exciting debut for the "DREWBEAR 63 variation"!
