Tomorrow is another day...

When I play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) I stay with the main lines and let my opponent do the innovating. Often he'll play a "Theoretical Lemon" (TL) rather than a "Theoretical Novelty" (TN).

The times when my opponent improves on past theory and play? Well, as they say, tomorrow is another day...

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8

As recently noted, this response has the highest success rate (56%) for Black in the games in the New Year's Database.

The move appeared first in Alonzo Wheeler Jerome's 1874 analysis of the Jerome Gambit in the Dubuque Chess Journal. The article contained an interesting caveat:

It should be understood that Mr. Jerome claims in this New Opening "only a pleasant variation of the Giuoco Piano, which may win or lose according to the skill of the players, but which is capable of affording many new positions and opportunities for heavy blows unexpectedly."

7.Qxe5 Qe7

A strong choice. An earlier game with the same opponent continued: 7...d6 8.Qg3 Qe7 9.d3 d5 10.0-0 dxe4 11.Re1 Qd6 12.Bf4 Qd4 13.Be5 Qd7 14.Rxe4 Qf5 15.Qxg7+ Ke8 16.Bg3+ Qxe4 17.dxe4 Black resigned, perrypawnpusher - frencheng, blitz FICS, 2010.

8.Qf4+

A similar idea (with a different response) was seen in blackburne - JFRAY, ChessWorld,  2004: 8.Qf5+ Ke8 9.0-0 d6 10.Qf3 Be6 11.Nc3 c6 12.d3 h6 13.Be3 Bxe3 14.fxe3 Nf6 15.d4 Rf8 16.e5 Nd5 17.exd6 Rxf3 18.dxe7 Rxf1+ 19.Rxf1 Kxe7 20.Nxd5+ Bxd5 21.b3 Rf8 22.c4 Rxf1+ 23.Kxf1 Be4 24.Kf2 Bb1 25.a3 Ba2 26.c5 Bxb3 27.e4 Ke6 28.Kf3 b6 29.Kf4 bxc5 30.dxc5 g5+ 31.Ke3 Ke5 32.Kd3 a5 33.g3 h5 34.h3 h4 35.g4 a4 36.Kc3 Bd1 37.Kb4 Kxe4 38.Ka5 Kd5 39.Kb4 Bxg4 40.Kxa4 Bxh3 41.Kb4 Bf1 42.a4 h3 43.a5 h2 White resigned 

A fundamental alternative at this point is for White to exchange Queens, something that Louis Morin ("mrjoker") has explored in a number of games.

An early experiment did not go well: 8.d4 Qxe5 9.dxe5 Ne7 10.Nd2 Ng6 11.Nf3 b6 12.0-0 Bb7 13.Re1 Re8 14.b3 Nxe5 15.Nd2 Ng4 16.Re2 Ke7 17.h3 Nxf2 18.Rxf2 Rhf8 19.Nf3 Bxe4 20.Bb2 Bxf3 21.gxf3 Rxf3 22.Re1+ Kd8 23.Ref1 Rxf2 24.Rxf2 Re2, White resigned, guest393 - guest664, ICC, 2001.

Morin is quite comfortable playing Queenless middlegames and endings with two pawns for a piece, as further games showed: 8.Qxe7+ Nxe7 (8...Bxe7 9.d4 d6 10.0-0 Nf6 11.Nc3 c6 12.f4 Ke8 13.h3 Be6 14.b3 d5 15.e5 Ne4 16.Nxe4 dxe4 17.f5 Bd5 18.c4 Bf7 19.e6 Bg8 20.Be3 h6 21.Rf4 Bh7 22.g4 Bf6 23.Rd1 Ke7 24.d5 cxd5 25.Bc5+ Ke8 26.cxd5 b6 27.Ba3 Rd8 28.d6 Be5 29.Rxe4 Bxd6 Black resigned, mrjoker - tomnoah, ICC, 2008) 9.c3 (9.0-0 d6 10.c3 Bb6 11.d4 h6 12.f4 g6 13.Be3 Kg7 14.Nd2 Bd7 15.Rae1 Rae8 16.Nf3 Bb5 17.Rf2 d5 18.Ne5 dxe4 19.c4 Ba6 20.b3 Nf5 21.Nd7 Bxd4 22.Bxd4+ Nxd4 23.Ne5 c5 24.Rxe4 b6 25.Re3 Rhf8 26.Rg3 Re6 27.h4 Rxf4 28.Rxf4 Ne2+ 29.Kh2 Nxf4 30.Nf3 Bb7 31.Nd2 Re2 32.Nf1 Rxg2+ 33.Rxg2 Nxg2 34.Ng3 Nxh4 White resigned, mrjoker - blunt7569, ICC, 2008) 9...Kf7 (9...d5 10.d4 Bb6 11.e5 Be6 12.0-0 Ke8 13.Na3 c5 14.Nb5 Kd7 15.Be3 cxd4 16.Nxd4 Nc6 17.f4 Nxd4 18.Bxd4 Bf5 19.h3 Bxd4+ 20.cxd4 Rac8 21.Rac1 Rxc1 22.Rxc1 Rc8 23.Rxc8 Kxc8 24.g4 Bb1 25.a3 g6 26.Kf2 Kd7 27.Kg3 Kc6 28.h4 Kd7 29.h5 Ke6 30.Kh4 gxh5 31.Kxh5 Bg6+ 32.Kh6 Be4 33.f5+ Kf7 34.Kxh7 Bf3 35.g5 Black resigned, mrjoker - Epimacus, ICC, 2009; 9...b5 10.d4 Bb6 11.0-0 d6 12.Be3 g6 13.Bh6+ Ke8 14.Nd2 Bd7 15.Rae1 Kd8 16.f4 Kc8 17.Bg5 Re8 18.h3 Kb7 19.g4 Ng8 20.Kg2 Rf8 21.f5 h6 22.Bf4 g5 23.Bg3 Rae8 24.e5 Bc6+ 25.Kh2 dxe5 26.dxe5 Rd8 27.Nb3 a5 28.Rd1 a4 29.Nd4 Bxd4 30.cxd4 Bd5 31.a3 c6 32.Rfe1 Ne7 33.Rd2 Rde8 34.e6 Nxf5 35.gxf5 Rxf5 36.e7 Kc8 37.Bd6 Kd7 38.Bc5 h5 39.Ree2 g4 40.Rf2 Rf3 41.Rxf3 gxf3 42.Rd1 Rg8 43.Rg1 f2 44.Rxg8 f1Q 45.e8Q+ Kc7 46.Qc8 checkmate, mrjoker - PhlebasP, ICC, 2008) 10.d4 Bb6 11.Be3 Rf8 12.Nd2 d6 13.0-0 Kg8 14.f4 c6 15.Rae1 Bd7 16.h3 Rf7 17.Kh2 Raf8 18.g4 c5 19.dxc5 Bxc5 20.Bxc5 dxc5 21.f5 Ng6 22.fxg6 Rxf1 23.gxh7+ Black resigned, mrjoker - PhlebasP, ICC, 2009.

8...Nf6 9.d3

In a relevant, correspondence game, Jerome himself faced his own gambit and survived: 9.Nc3 c6 10.d3 d6 11.h3 h6 12.0-0 g5 13.Qg3 Qe5 14.Ne2 Qxg3 15.Nxg3 Ke7 16.c3 Be6 17.a4 a5 18.Be3 Ba7 19.d4 Rag8 20.f4 gxf4 21.Bxf4 d5 22.Be5 Rf8 23.exd5 cxd5 24.Rae1 Rhg8 25.Nf5+ Kd7 26.Nxh6 Rg6 27.Nf5 Ne4 28.Ne3 Rxf1+ 29.Rxf1 Bb6 30.g4 Bd8 31.Kg2 Kc6 32.b3 Bg5 33.Nd1 Nd2 34.Rh1 Bh4 35.b4 axb4 36.cxb4 Nc4 37.Nc3 Nxe5 38.dxe5 d4 39.Ne4 Bd5 40.Kf3 Rg8 White resigned, Jaeger - Jerome, correspondence 1880.

A significant improvement over 12...Qe5 of perrypawnpusher - jonathankochems, blitz FICS, 2010, which continued 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

13.Bd2

Stronger was 13.Be3, although Black would still have the advantage.

13...Kg8

Black has castled-by-hand, has the two Bishops, and plans to swap off White's advanced Knight, leaving doubled pawns.

White needs to stir up some trouble before the game simply settles down to being bad for him.

14.Qg3 Nxd5 15.exd5 Qf6 16.Bc3

16...Bd4 17.Rae1 Bxc3 18.bxc3 b6

19.c4 Bb7

Black's Bishop will "bite on granite" here, but the move connects his Rooks.

20.Re6 Qc3 21.Re7 Rac8

The first good news that I've had in a while: my opponent is uneasy with my Rook on the seventh. How uneasy?

22.Rfe1 Qf6

That's uneasy enough for me.

It clearly was time to go for the draw by offering to repeat the position, before my opponent thought otherwise. 

23.R1e6 Qd4 24.Re4 Qf6 25.R4e6 Qd4 26.Re4 Qf6 27.R4e6 Qd4 28.Re4 Qf6 29.R4e6 Qd4 30.Re4 Qf6 31.R4e6 Qd4 Game drawn by repetition
 
I was happy to split the point here – tomorrow, after all, is another day.

Losing – and Then Winning – the Won Game

It has been said that in chess "the hardest thing to win is a won game." I'm not sure that I  fully agree – it's hard to win a lost game – but I understand the thought. Once you achieve a significant advantage – especially playing a disreputable opening like the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) – there's a tendency to act as like the game will play itself.

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6

This move appears frequently, as if by reflex: White has sacrificed recklessly and now brings out his Queen too early? I'll kick it!

7.Qxe5 d6

 

Blackburne's Variation.

8.Qxh8 d5

My opponent spent time on his moves, and I wondered if he was familiar with the Jerome Gambit. Was he simply double-checking the lines? His move says "no", but I'm not sure: after the correct 8...Qh4, recommended for White is 9.d4; so perhaps sarenn merely mis-remembered?

9.Qxh7+ Kf8 10.Qxg6 dxe4 11.Qxe4 Nf6 12.Qe2

White is ahead the exchange plus four pawns.

Black is about to unleash a counter-attack, but it should be possible to survive it.

12...Bg4 13.f3

13...Bf5

More in the style of Blackburne was 13...Qd7, as 14.fxg4 is met by 14...Re8, and after 15.Nc3 Qxg4 16.d3 Rxe2+ 17.Nxe2 Qxg2 18.Rf1 White's advantage has shrunk considerably.

14.d3 Nd5

15.Nc3 Nxc3 16.bxc3 Qh4+

17.g3 Qf6 18.Kd2

Just what my opponent was hoping for.

I was worried about 18...Re8, winning my Queen for a Rook (as in the note to move 13, above). I overlooked the defensive gem 18.d4, which blocks out Black's dark-squared Bishop, allowing me to castle and also to play Bc1-e3 (in response to ...Ra1-e8) to protect my Queen. 

For his boldness, Black now has the advantage.

18...Re8 19.Qg2

Approaching panic. Sadly, White's best was to give up his Queen and work on development: 19.Re1 Rxe2+ 20.Rxe2 Bd7 21.Bb2 Qxf3 22.Rae1 Qf6 23.d4 Bd6 24.Kc1 although even then, Black would be better.

analysis diagram

19...Be3+ 20.Kd1 Qxc3

This looks scary, but I was lucky that my opponent missed the shot 20...Bh3.

It's hard to believe, but Rybka now sees the position as even.

21.Rb1 Bxd3

After he finishes destroying me, my opponent can tell his pals that all those Kingside pawns of his were "sacrificed," not "lost".

22.Bxe3 Bxc2+

Since this move loses for Black, the question is: what else did he have?

After the game Rybka suggested 22...Rxe3 23.Qd2 Bxc2+ 24.Qxc2 Rd3+ 25.Kc1 Qa3+ 26.Rb2 Rc3 27.Rf1 Rxc2+ 28.Kxc2. White would have two Rooks and a pawn vs Black's Queen, which looks about equal.

analysis diagram







23.Qxc2 Rd8+

24.Kc1

An error that prolongs Black's attack. Giving back a Rook was the way: 24.Bd2 Qxf3+ 25.Kc1 Qxh1+ 26.Kb2. With White's King safe, the extra piece would be very helpful in attacking Black's King.

analysis diagram





24...Qxe3+ 25.Kb2

25...Qd4+

In the heat of the moment, Black gives up his last chance to keep the game even by settling for a Q vs 2R ending: 25...Rd2 26.Rbc1 Rxc2+ 27.Rxc2 Qxf3.

26.Qc3 Qf2+ 27.Ka1 Qxf3 

An error that ended the game, even after my inaccurate reply.

28.Rhf1 Black resigned

Declining the Jerome Gambit - Légally

Given that my favorite opening, the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+)has so many refutations, I'm constantly amazed at the number of people who go out of their way to decline the fool thing.

I need to have a whole new set of ideas if I want to win my games!

Goodbye, King.

This well-known opening trap is credited to the French player M. de Kermar, Sire de Légall (1702-1792). It also is sometimes called the Blackburne Trap, since the English player Joseph Blackburne (1859-1951) used to catch so many players in it! It can arise in a number of different move orders, and it's one of those traps you need to be aware of so you don't fall victim to your own greed! Learn to recognize the pattern you see in the following examples.

The rest of David Surratt's article on Légall's Mate is at Chessville.

A Simple Game (?)

I was having fun playing my most recent Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). It seemed like a simple, straight-forward game. Afterward I gave it to Rybka to look over, and I found that things are not always as simple as they seem...

Black's Queen move is a good one — which I under-estimated during the game. Now, against best play, White cannot both support his center and move it forward on the attack.

16.Be3

I was unhappy with this move (I could not think of anything better) and was even unhappier after the game when I saw what Rybka had suggested that I play instead: 16.Qd3 Ne5 17.Qd1 Ned7 18.Qd3 Kg8 19.b3 c5 20.Be3 cxd4 21.Bxd4 Qc6 22.Rf4 Ne5 and Black is better.

This line needs some serious examination for White, starting with 10.Nc3

16...Nxe3 17.Qxe3 d5

This is part of the reason that the game seemed simple to me at the time: Black hits my center with his d-pawn and I advance my e-pawn to bypass it. Instead, though, Black had 17...c5 when 18.Rad1 cxd4 19.Rxd4 Bd7 and again White's pawns have been banged up and the second player is better.

18.e5 Ng4

Unnecessarily aggressive, moving the game toward equality. The cold-blooded 18...Kg8 was the right idea, as the White e-pawn is pinned to the Queen.

19.e6+

Rybka evaluated this as too early, preferring 19.Qf4.

19...Kf6

This was Black's last chance to finish castling-by-hand with 19...Kg8. Instead, he steps into the line of fire.

20.Qf4 Bxe6

It is not the time to return the piece for two pawns, although neither retreating nor protecting the Knight will help, either.

21.fxe6+ Kxe6 22.Rae1+ Kd7

The "Jerome pawns" are gone, but the files they have opened will win the day.

23.Qxg4+ Kd6 24.Qf4+ Kd7 25.Qf7+ Black resigned

Jerome Gambit Nomenclature

Jerome Gambit Gemeinde member Bill Wall has been working on an orderly way of naming the various Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) variations.

Sometimes a move or line is given a generic label (e.g. "5.a3 Variation"), but when possible it is given the name of the person known to have played it first.

(This is based upon my 9 years of research into the Jerome Gambit. Of course, further discoveries may change things.)

There are a few exceptions (e.g. 5...Kf8, the "Sorensen Variation"), where the name given refers to someone who did significant analysis of the line, or greatly popularized it (e.g. 7...d6, the "Blackburne Variation").
