Repairing a Variation (Part 3)

The next step in repairing a variation, after you have defined the problem (Part 1) and reviewed some game history (Part 2), is to see what has been written about the line.

Unfortunately, when you are dealing with a variation of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), reading up on the "His Nibs" Variation (4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Ke6 8.f4 Qh4) can be done during a coffee break.
There are only two sources in print that I have been able to find in about 8 years of study of the Jerome Gambit.

The first, in Randspringer #6 1990-1991, was in an article by Jack Young, author of many hysterical "Bozo's Chess Emporium" articles for Chess Horizons.

"Meet Jerome"

The Jerome Gambit (also known as the "Kentucky Opening" according to Blackburne), like the Reynolds Gambit, like the Chicago Gambit (1.e4 e5 2.Nf3 Nc6 3.Nxe5!! Nxe5 4.d4), like the Fred (1.e4 f5!!) desrves to be in the arsenal of every serious tournament player. Don't know the Jerome? That's OK but if you play through the following game I would not be surprised if it convinced you to venture the Jerome in your next serious tournament game. This important theoretical battle featured some real "high caliber" opposition and makes a good case for the playability of the Jerome Gambit...

...Young - Computer, 1991: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+! Kxf7 5.Nxe5+! Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4?! Another computer defused the attack after 8...Qh4+ 9.g3 Qf6

I admit that this is only a snippet of a mention, but I include it for a couple of reasons. First, it is also the first game (even if a partial) after "R.F" - "Nibs", 1899, that I have in my database. Secondly, it shows that the Black Queen check-and-return was primarily to disrupt White's kingside, not the beginning of a complicated Queen sacrifice.

The second reference I reviewed is from the unusual chess book Unorthodox Chess (2005), by the even more unusually-named author, Some Loser. (I reviewed the book for Chessville here.)

...the Jerome Gambit - an old favorite of mine, back in the good old days when I used to imagine I could get away with anything. It goes like so: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+!! Kxf7 5.Nxe5+! Nxe5 6.Qh5+ White will be able to recover one of the sacrificed pieces, after which Black's exposed King position plus the two Pawns, not to mention the fabulous shock value, almost compensate for the other piece. Ah, those were the days... and hard to swallow as it may seem, it has actually been known to work from time to time.
For instance 6...Ke6?! 7.Qf5+ Kd6 8.f4 Qh4+?! 9.g3 Nf3+ 10.Kf1 Nxh2+?! 11.Kg2 Qd8 [11...Qg4 12.Qd5+ Ke7 13.Qxc5+ d6 14.Qf2 Nf6 15.Rxh2 Nxe4 16.Qe3 Qe6] 12.Qd5+ Ke7 13.Qxc5+ d6 14.Qg5+ Ke8 15.Qxd8+ Kxd8 16.Rxh2 Nf6 17.d3 Ng4? 18.Rh4 Nf6 19.Be3 Bg4?! 20.Bd4 Bd1? 21.Na3 Be2 22.Kf2 Bxd3 23.cxd3 c5 24.Bxf6+ gxf6 25.Nc4 Ke7 26.Ne3 Kf7 27.Rah1 Kg6 28.Rh6+ Kg7 29.Nf5+ Kg8 30.Rxf6 d5 31.Nh6+ Kg7 32.Rf7+ Kg6 33.e5 Rhg8 [33...Rab8 34.f5+ Kg5 35.Rg7#; 33...Rag8 34.Rf6+ Kg7 35.Nf5#] 34.Rf6+ Kg7 35.Nf5+ Kh8 36.Rxh7+ Kxh7 37.Rh6#

The lesson from Some Loser's game (or analysis, it is not clear from the text) is that the White King move 10.Kf1 is not an improvement over abhailey's and R.F.'s 10.Kd1. This was confirmed in both perrypawnpusher - james042665, Chess.com, 2008 (0-1, 18) and perrypawnpusher - Temmo, chessworld.com, 2008 (0-1, 43), even though both defenders did not follow the best line of play.
Black's 10...Nxh2+ vs Some Loser was a mistake which surrendered the second player's advantage. As in abhailey - peonconorejas, net-chess, 2008, the best move was 10...Ne7 with similar powerful play against White's Queen and King. Also, 10...Qd8 gave White the advantage, whereas 10...Qg4 would have led to an equal game.

A Dangerous Place

In a chess game, like when on a long walk, if you're not paying attention to where you're going, you could wind up in a dangerous place. If you happen to be playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) you are almost certain to find some danger.
I think that my opponent, electrahan, knew something about the Jerome Gambit. Our game quickly travelled to a very complicated line of defense – nothing like the Najdorf Sicilian, but Jerome Gambit Tournament: Chapter XVI and Jerome Gambit: Fools walk in... are almost "required reading" to appreciate what follows.

perrypawnpusher - electrahan
blitz 9 5, FICS, 2009

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

Welcome, Mr. Electrahan, shall we go for a walk?
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6
7.Qf5+ Kd6 8.f4 Qh4+
As far as you are willing to go, Mr. Pawnpusher...

Sometimes referred to as "His Nib's Defense," (see "Jerome Gambit Tournament: Chapter II") this line has caused me no small amount of headaches. And excitement. And wonder. There's a Queen sacrifice hidden somewhere, and even if it doesn't come off, the game becomes very unclear.

9.g3 Nf3+
Before this game I had losses to Temmo (0-1, 43) and James042665 (0-1, 18) in this line.

10.Kd1
This is the line that "R.F." originally played against "His Nib's", but in my earlier games I had preferred 10.Kf1, which was the better choice.

Now Black can sacrifice his Queen (as in abhailey - peonconorejas, net-chess.com, 2008, 0-1, 20) with 10...Ne7 11.e5+ Kc6 12.Qe4+ d5 13.exd6+ Nd5 14.gxh4 Bg4 and win – but you really have to know the line, as it would be difficult to suss out over-the-board in blitz.

10...Qh6
This retreat – which is similar to Temmo's Queen retreat (with my King on f1) and Kevin the fruitbat's Queen retreat to f6 in a comparable position (perrypawnpusher - Kevin the fruitbat, chessworld, 2008, 1-0, 38) – still leaves Black with a slight advantage.

11.Qd5+ Ke7 12.Qxc5+ Qd6 13.Qxd6+ cxd6
The same dilemma that I faced against Temmo: if the advanced Black Knight stands, the second player is better; but if it falls, I am even, and may have the advantage.

My one advantage against electrahan was that I was more familiar with the positions and play, and so was significantly ahead on the clock.
14.c3

To keep the Knight put.

After the game Rybka 3 recommended 14.b3 Nf6 15.Bb2 d5 (working to free the Bishop) with complications and a rather unclear game after either 15.exd5 or 15.e5.

14...Nf6
A sensible move, although Fritz8's 14...d5 and Temmo's 14...g5 were more likely to keep Black's edge.

15.d3

Stronger was the immediate 15.Ke2

15...b6
Black has settled upon his defensive plan: it involves ceding the Knight.

16.Ke2 d5 17.Kxf3 dxe4+ 18.dxe4 Bb7
19.Re1 Kf7 20.Nd2 Rhe8 Black has some compensation for his two pawns in the congestion of White's Queenside.

21.g4 d5

Instead, 21...Nxe4 22.Nxe4 Rxe4 23.Rxe4 Re8 24.Be3 Bxe4+ 25.Kf2 d5+ held chances of a drawn Bishops-of-opposite-colors endgame.

22.e5 d4+ 23.Kg3 dxc3 24.bxc3 Nd5
25.Bb2 Rad8 26.Ne4 Nf6 This does not work out, and is likely the result of time issues.

27.Nd6+

Good enough, but 27.Ng5+ Kg8 28.exf6 was stronger.

27...Kf8 28.Nxb7
Again, 28.exf6 was stronger, but the text works. Black's game unravels.

28...Rd7 29.Ba3+ Kf7 30.Nd6+ Rxd6 31.exd6
31...Ne4+ 32.Rxe4 Rxe4 33.Kf3 Rc4 34.d7 Rxc3+ 35.Ke4 Black forfeited on time

Jerome Gambit Tournament: Chapter XVI

Here is my favorite game of the tournament.


I had White, playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+).


I lost.

Hats off to Temmo for a fascinating game!


perrypawnpusher - Temmo
JG3 thematic http://www.chessworld.net/ 2008

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Qh4+



As played against me by drewbear ("Jerome Gambit Tournament: Chapter II") and Kevin the fruitbat ("Jerome Gambit Tournament: Chapter XIII") in this tournament, and James042665 ("Fools walk in...") more recently.

The line has lots of confusion for White, and a possible Black Queen sacrifice (i.e. abhailey - peonconorejas, net-chess.com, 2008, "Jerome Gambit Tournament: Chapter II") to keep things lively.

9.g3

No more innovations like 9.Kd1, perrypawnpusher - drewbear, JG3 thematic, http://www.chessworld.net/, 2008 (0-1, 10)

9...Nf3+ 10.Kf1 Qh6


If you happen to have the quirky tome Unorthodox Chess, by the pseudonymous Some Loser, you would find the alternative 10...Nxh2+ in one of his games: 11.Kg2 Qd8 12.Qd5+ Ke7 13.Qxc5+ d6 14.Qg5+ Ke8 15.Qxd8+ Kxd8 16.Rxh2 Nf6 17.d3 Ng4? 18.Rh4 Nf6 19.Be3 Bg4?! 20.Bd4 Bd1? 21.Na3 Be2 22.Kf2 Bxd3 23.cxd3 c5 24.Bxf6+ gxf6 25.Nc4 Ke7 26.Ne3 Kf7 27.Rah1 Kg6 28.Rh6+ Kg7 29.Nf5+ Kg8 30.Rxf6 d5 31.Nh6+ Kg7 32.Rf7+ Kg6 33.e5 Rhg8 34.Rf6+ Kg7 35.Nf5+ Kh8 36.Rxh7+ Kxh7 37.Rh6 checkmate Some Loser - NN.

11.Qd5+ Ke7 12.Qxc5+ Qd6 It's probably better to leave the Queens on the board with 12...d6. It doesn't look like a big deal, but if the analysis given below of a 14th move alternative for White is accurate, then it is here that Black loses his advantage.

13.Qxd6+ cxd6

`Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.
(from Through the Looking-Glass and What Alice Found There, 1872)

Is the Knight at f3 vulnerable? If so, then White probably will find an even – if unclear – game.

Is the Knight Black's only source of worry? What about the a1-h8 diagonal?

After the hammering White took in the game perrypawnpusher - James042665, Chess.com 2008, we will probably see 10...Qf6 far more often than this game's 10...Qh6, so there may not be other games to address these (and other) questions.

Pity.

14.c3

Played to keep the Knight from running away, but Rybka gives an interesting alternative in 14.b4!? -- when best play has the piece staying a moment, as 14...Nd4 15.Bb2 Ne6 16.f5 seems to require the answer 16...Nf6, when 17.Bxf6 (better than the pawn capture) gxf6 18.fxe6 dxe6 gives White a small advantage.

After 14.b4!? b6 15.Kf2 Nd4 it's still an unclear game: 16.Bb2 Nxc2 17.Bxg7 Nf6 18.Bxh8 Nxe4+ (better than the immediate capture of the Rook with 18...Nxa1) 19.Kf3 Nc5 (an amazing move; Black also has 19...Bb7 20.Rc1 Nc5 21.Ke2 Ba6+ leading to a draw by repetition) 20.Ke2 Bb7 21.Rc1 Ba6+ 22.Kd1 Nxb4 23.Bd4 Ncd3 where Rybka suggests as best that Black can force a draw.

14...g5

On a rescue mission!

15.Kf2

The King is probably better-placed after 15.Kg2, after which the battle over the knight would continue with 15...g4 16.h3 d5 17.exd5 d6 18.hxg4 Bxg4 although Black would have an edge after 19.Rf1 h5 20.Rxf3 Bxf3 21.Kxf3 h4 22.gxh4 Rxh4 – White has three pawns for the exchange, but Black's development would more than compensate.

15...g4 16.h3 d5 17.hxg4

Capturing the d-pawn first was better.

17...dxe4 18.d3 d5 19.g5

Giving up on the "undermining" mission, and seeking to delay the development of the other Knight, which would in turn delay the development of a Rook.

19...h6

Black understood what I was getting at, and worked to counter it; but the more straight-forward 19...Bf5 would have helped his development

20.dxe4

If first 20.c4 Bg4 21.dxe4 dxe4 22.Nc3 Re8 23.Nxe4 the pawn center would have been destroyed, and White would have crept closer to equality.

20...dxe4 21.Nd2 Nxd2 22.Bxd2 Bg4 23.Be3

White had the interesting 23.Rh4 instead, although after 23...h5 24.Rah1 Bf3 25.R1h2 Ke6 26.g4 Bxg4 27.Rxg4 Nf6! Black wins the exchange and retains the better game.

23...Ke6 24.Rh4 Kf5

Here Rybka comes up with another interesting idea for White: sacrificing the exchange! 25.Rxg4 Kxg4 26.Rh1 Kf5 27.Rh4 Rd8 27.g4 Kg6 28.g4 Kg6 29.Ke2 a6 30.f5 Kg7 31.gxh6 Nxh6 32.Bd4 Rxd4!? 33.cxd4 Rc8 and too many of White's pawns look like targets.

25.Bd4 Rh7 26.Rah1 h5 27.Ke3

Rybka suggests the exchange sacrifice again, 27.Rxg4 etc. to reduce Black's advantage. Once Black gets his pieces untangled, the game more and more favors him. His King easily handles the White pawns.

27...Ne7 28.R4h2 Nd5+ 29.Kd2 b6 30.Re1 Re8 31.Be3 Rd8 32.Kc2 Rc7 33.a3 Rcd7 34.Bd4 b5 35.Be5 Rc8 36.Kb1 a5 37.g6


A frail whisp of hope. A mirage.

37...b4 38.axb4 axb4 39.g7 b3 40.Bd4 Kg6 41.Kc1 Kf5 42.Rhh1 Nb4 43.Kd2 Rxd4+
White resigns.


What a game!

Jerome Gambit: Fools walk in...

With all of the refutations, games, and analysis of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) that I've posted on this blog you would think that I would not be foolish enough to actually play the opening again.

Of course, you might think I wouldn't have been foolish enough to ever have played the Jerome Gambit – but it's too late for that.
Here's a recent "lesson" in the Jerome Gambit for me – Ouch!

Hats off to my new "instructor," James042665 at Chess.com.
perrypawnpusher - james042665
Chess.com, 2008
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Qh4+

Jerome Gambit Refutation Number I-Forget, as seen in "Jerome Gambit Tournament: Chapter II" and "Jerome Gambit Tournament: Chapter XIII".

9.g3 Nf3+ 10.Kf1
A line I first played against Temmo in our Jerome Gambit Tournament game, to be covered in more depth when I get to annotate it in Chapter XVI. The impact of the pesky Black Knight is more significant than in my game against Sir Osis ("Jerome Gambit Tournament: Chapter III").

10...Qf6
This Theoretical Novelty makes perfect sense.

11.Qd5+ Ke7 12.Qxc5+ Kd8 13.Kg2 d6 14.Qd5
The simple retreat 14.Qf2 was best, and after 14...Nd4 15.d3 White would have the imbalance typical in the Jerome Gambit: two pawns vs a piece. Of course, Black would still be better.

14...Ne7 15.Qd3 Nd4 16.e5
Here I thought that I was going to win that annoying Knight, but I should have been satisfied with getting back on track with 16.c3 and an eventual d2-d4.

Now my game caves in.
16...dxe5 17.c3
Later, Rybka informed me that this leads to mate, starting with 17...Qc6+ 18.Kf2 Qxh1. Yikes!
17...Bf5

Good enough.

18.fxe5 Qc6+ White resigns.
Answering, again, the basic question raised much earlier: "But - Is this stuff playable? (Part I)"
Of course not.
