A Side Line to Watch


When my opponent unleashed his 7th move in our Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, the only surprise came later, when I realized that it was the first time the move had been played against me.

It's a side line that all who play the Jerome should be ready for.

National Master Brian Wall discussed this kind of move, when made by a lower-rated player, in one of his games. I figured my opponent (my strength) was thinking

Only a patzer would try an attack like this! I can disrupt his crazy attack, swap Queens, and then easily wallop someone I could probably give a knight to, not just a pawn...

White is up a solid pawn – and remember, a few moves ago, he was down two pieces.

Both Kings have castled-by-hand, and Black is slightly ahead in development – but not a pawn's worth. Maybe he planned to out-play me here, but it didn't work out that way.

Sometimes you just have to outplay the other guy...

It's not like you can simply play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and win as you please -- in fact, it's kind of like the opposite.

What it comes down to is that sometimes you just have to outplay the other guy.

Or, failing that, you have to make the next-to-last mistake and let him make the last one...

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 7.Qxe5 Bxf2+



This strategy is similar to the one employed by Pederson (see "Jerome Gambit Strikes in Denmark!") after his 6...g6.8.Kxf2 Qf6+ 9.Qxf6+ Nxf6


"A rather unambitious line on Black's part" as Jerome Gambit Gemeinde member Martin Moller commented in his game against Pederson.

Same here. I'm a pawn up in a balanced position. With some steady work, my advantage should prove itself.

10.Nc3 d6 11.d3 Ke7 12.Bg5 Rf8 13.Rhf1 Ke8 14.Bxf6 Rxf6+ 15.Ke3 Rxf1 16.Rxf1 Be6

If my opponent was content to play against me a pawn down, perhaps he was pleased here with his Bishop vs Knight advantage.

17.a3 Ke7 18.d4 Rf8

Consistent, but not a good idea. Keeping my Kight limited with 18...c6 looks better.

19.Rxf8 Kxf8 20.Nb5 c6 21.Nxa7


Capturing the d-pawn (and, incidentally, making the e-pawn a passer) was less risky.

21...Ke7 22.b4 d5 23.e5 Kd7 24.b5 Kc7 25.bxc6 bxc6 26.a4 Kb7


I have to admit that "losing a Knight" is not the same as "outplaying your opponent".

Even so, White probably can draw by abandoning his piece and a-pawn and focus on marching his King to e8 (or f8 or g8) to help his e-passer promote.

27.Nb5 cxb5 28.axb5 Kb6 29.h3 Kxb5



In a blitz game, anything can happen. Black was willing to play on a pawn down, and he is now clearly winning.

All I had to console myself with was the idea that the guy who allowed White an advantage in the Jerome Gambit was the same guy who let me move through a middle game where White was better. Perhaps he would be just as strong in the endgame.

30.g4 Kb6 31.Kf4 h6 32.h4 Kc6 33.g5 Kd7 34.gxh6 gxh6 35.Ke3 Bf5 36.Kf4 Ke6



Readers with endgame skills are probably beginning to snicker.

37.c3 Bd3 38.Kg4 Be4 39.Kh5 Bd3 40.Kxh6 Kf5


The last two moves have been critical.

With the capture of the pawn, White gained a drawn position: Black's Bishop and King can keep either passer from Queening.

Black's King lurch, however, has given White the advantage. He should have tried something like 40...Be2 when White can make little progress, e.g. 41.Kg5 Bd3 42.h5 Ke7 43.h6 Kf7 44.Kh5 Be4 45.Kg5 Bd3.


41.h5

Well, that didn't last very long. The proper move was 41.Kg7. Now Black can play 41...Be2 and hold the draw.

41...Kg4

Did I mention that this was a blitz game?


42.e6 Bb5 Ok! White is winning again.


My opponent played on, though, no doubt thinking "This guy played the Jerome Gambit against me -- how good could he be?"


43.e7

Back to zero.


It is a challenge to juggle two passed pawns, the opponent's pawn and his Bishop, but it can be done: 43.Kg6 Be8+ 44.Kf6 Kxh5 45.Ke5 Bc6 46.Kd6 Ba4 47.Kxd5 5.19/19 Kg6 48.Kd6 Bb5 49.Ke7 Bc4 50.Kd7 Bb5+ 51.Kd8 Kf5 52.e7 Ke4 53.e8Q+ Bxe8 54.Kxe8 etc.

43...Kf5

The game takes its last rude turn.

After 43...Be8 44.Kg7 Bxh5 the outside passed pawn is captured, and Black has only to trade his Bishop for the other passed pawn with 45.Kf8 Kf5 46.e8Q Bxe8 47.Kxe8 and then "oppose" any attempt by the White King to come to the aid of his pawns: 47...Ke6, etc.

44.Kg7 Kg5 45.h6 Black resigns

Jerome Gambit Strikes in Denmark!



Hi Rick,

Already the first game is decided in my Jerome gambit thematic tournament, and in my favour.!!
Before the tournament began I searched my Jerome file for White wins, and arranged them in variation order.
Here is the game : start 8/10-2008, end 15/10-2008

White: Martin Moller
Black: Jan Pedersen

www.eskak.dk , 10.2008
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Bxf2+ 8.Kxf2 Qf6+
A rather unambitious line on Black's part, I think, forcing the exchange of Queens, and White is a pawn up (we were following game no. 209).

[I agree, Martin: my database has 11 games with this line and White has won 10, the only loss coming in a mis-played Rook-and-pawn endgame. – Rick]
[When NM Brian Wall played against this line, he commented "Luckily, there is an unwritten Law of Chess that states a lower rated player will trade any advantage, no matter how massive, for a certain draw against a higher rated player. The Law is based on the principle that the lower rated player knows in his heart he never deserves to win, no matter how well he has played... Black sees an "opportunity" to trade queens and grabs it with both hands."]
