A Day in the Life of the Jerome Gambit

After the quite unusual checkmate that ended niddrieboy's Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game at Chess.com (see "Jerome Pawns Triumphant"), I thought it might be fun to walk through one of his games that readily illustrates the highs and lows, attractions and pitfalls of that offbeat opening.

niddrieboy - paul_kowtun
Chess.com, 2010

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


As Max said in Where the Wild Things Are, "Let the rumpus begin!"

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


The Jerome Variation (see "Jerome Gambit Nomenclature").

7.Qxe5 Qe7 8.Qf4+ Nf6 9.e5


In two 1880 correspondence games against Daniel Jaeger, Alonzo Wheeler Jerome, playing the Black pieces against "his" gambit, continued 9.Nc3 c6 10.d3 d6 11.h3 h6, winning both.

It should be remembered that Jerome did not believe that the gambit won by force, only that it was

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.
9...Ke8

This looks like Black's original plan was to make room for his Rook at f8, facing off with the White Queen an idea he subsequently discarded. He would have done well simply to have attacked and won the e-pawn with 9...d6 10.d4 dxe5 11.dxe5 Bd6 12.0-0 Bxe5 when White's pawn and Black's displaced King are not sufficient compensation for White's sacrificed piece.

The second player's judgement is being clouded by the unusual play, something that Jerome Gambiteers love to see.

10.d4 Nd5 11.Qe4 Nf6 12.Qd3 Bb6 13.0-0 Ng8


Black's Knight retires from the field out of either frustration or confusion.

14.c3

Bolstering his center. He might even have tried the aggressive 14.c4.

14...Qf7 15.Be3 d6 16.exd6 Nf6 17.dxc7 Bxc7


Black has cleared his head and decided that it was worth a pawn to get his pieces, especially the Bishop pair, more active. He still has to be careful about his King (that is why 17.Re1 was probably better than 17.dxc7) but dynamic play will give him plenty of chances.

18.Re1 Kd8 19.Bg5 Qh5 20.Bxf6+ gxf6 21.h3


White can see danger ahead, with the two Black Bishops and the White Queen pointed at his Kingside. He may have chosen the text instead of 21.g3 because he could visualize the Black Queen moving (perhaps to g6) and then the Black h-pawn advancing h7-h5-h4, opening up the h-file for the Black Rook...

Nonetheless, Rybka recommends 21.g3 to keep the game in balance.

21...Rg8 22.Re3

Instead, Rybka suggests that both players head toward the endgame, White because it is safer than the middle game and Black because the two Bishops continue to give him the advantage: 22.Kf1 Bf5 23.Qc4 Qg5 24.Qd5+ Kc8 25.Qf3 Qf4 26.Nd2 Qxf3 27.Nxf3 Kd7 28.Rad1 Rae8 29.Rxe8 Rxe8 30.Re1 Bd3+ 31.Kg1 Rxe1+ 32.Nxe1 Be4.




analysis diagram








By simple count, White has 3 pawns for his sacrificed piece, but both Rybka 3 and Fritz 10 value Black's position as being over a pawn ahead. Would niddrieboy have been safer to have chosen this line? Probably.

22...Bf5 23.Qe2

White might have been asking himself How did I ever get into this miserable position?

23...Qg6

As often happens in Jerome Gambit games, Black chooses a good move – and overlooks a great move.

With 23...Rxg2+ he could have smashed White's King's fortress and at the very least created a nasty cramp on White's position with 23.Kf1 Qxe2+ 24.Kxe2 Rg1. If White fell for the Rook with 23.Kxg2 he would face 23...Bxh3 and then he could give up his Queen with 24.Rxh3 Qxe2; be checkmated with 24.Kh1 Be4 25.f4 (ouch!) Rxe2+ 26.Kg1 Qg6+ 27.Rg3 Qxg3+ 28.Kf1 Qg2#; or simply suffer until death with 24.Kg1 Qg5+ 25.Rg3 Bxg3 26.fxg3 Qxg3+, etc.

24.Qf3

White opens his eyes cautiously... I'm still alive! If only I had a magic trick to keep me in the game...

24...Bxb1

Winning a piece and going two pieces up. It's not like Black overlooked 23...Rxg2+ for nothing...

25.Qd5+

When everything is going wrong in the Jerome Gambit, White can turn over his King and think about another game – or he can hang on, giving ground slowly, waiting for any kind of a chance to recover.

Like, for example, 25.Qxb7, instead of the text. After that move White has a draw through repetition by checking Black's King. Of course, the second player can escape this by giving back material (a Bishop with 25...Be4 or a Rook with 25...Qxg2+) but that gives White at least equality, and probably an edge.

25...Kc8 26.Re7

We fight! White's pieces cry. Against a computer, this would be folly, but against a human, even "objectively" won games have to be played out.

26...Bf5

A more effective way out of White's pressure was 26...Rd8 27.Qc4 Rd7 28.Qe6 first, then 28...Bf5.

27.Qf3

It might have been time for the gutsy 27.g4, although Black can give his extra piece back with 27...Bxg4 28.hxg4 Qxg4+ and it will be a battle to see who can checkmate who first.

Now White is in for a bit of suffering.

27...Bd7 28.d5 Bd6 29.Re4 b6 30.Rae1 Be5 31.R1e2 Kb7


Sanctuary!

32.c4 Raf8 33.R2e3 Bd6 34.Rb3 Bxh3 35.Re7+


No doubt this move was seen as a pesky fly that just needed to be swatted away. Clearly Black is about to crush White's Kingside like an eggshell...

35...Bxe7 36.d6+ Kc8


Shooo, fly!

It is true that with 36...Kb8 37.dxe7 Black would have to return a Bishop – but, after all, he had received a Rook for it, so that was no problem. Things can be tied up with 37...Qxg2+ 38.Qxg2 Rxg2+ 39.Kf1 Rg7+ 40.Rxh3 Rxe7 and Black sails off into the sunset with an extra Rook.

Does it make a difference that he played 36...Kc8, instead?

It turns out the answer is YES!


Surprisingly enough, White now has a forced checkmate.

37.Qa8+ Kd7 38.Qb7+

At first glance, it would hardly seem to matter if White checked from b7, or captured a pawn, checking from a7.

It turns out, though, that Black's King can now find a hole in the mating net, one that would have remained closed if White could have played Qxb6+ on his next move. That capture and check would only be reasonable if the pawn on b6 were not supported by the pawn at a7...

After 38.Qxa7+ Kxd6 39.Qxb6+ Kd7 40.Qc5+ Black's King will not escape to the Kingside, and as soon as White's Rook joins the check-fest it will be checkmate.

Alternately, after 38.Qxa7+ Ke6 White's Queen and Rook are deadly on the other side of the board: 39.Qxe7+ Kf5 40.Rf3+ Kg4 41.Qe6+ (more tap-dancing on the light squares) f5 42.Rg3+ and Black's King is doomed.

So, 35.Re7+ was part of a great swindle befitting the Jerome Gambit – but it didn't quite come off. As Maxwell Smart used to say, Missed by that much...

38...Kxd6 39.Rxh3 Qxg2+


White wound up getting the other of the two Bishops for his Rook, but Black now liquidates the situation, showing that even after giving back a Rook, he still holds the advantage.

What is it about the Jerome Gambit that makes its opponents act that way?

40.Qxg2 Rxg2+ 41.Kxg2 Kc5 42.Rxh7 Re8


43.b3

Again, niddrieboy decides to hang on.

This might seem odd to those who glance at the position and think "Up a piece in an edgame? Won for Black." However, the Jerome Gambit player asks himself "Suppose the pawns all come off the board – how hard would it be for Black to win the R + B vs R endgame? How much time does he have on the clock, anyway?"

In this regard, this Rybka-inspired line is interesting: 43.Kf3 Kxc4 44.Rh4+ Kd5 45.Re4 f5 46.Re3 Kd6 47.Kf4 Kd7 48.b3 Bd6+ 49.Kxf5 Rf8+ 50.Ke4 Rxf2 51.a4 Rf4+ 52.Kd5 Rf5+ 53.Kc4 Kc6 54.Re4 a6 55.Re3 Rf4+ 56.Kc3 Bc5 57.Rh3 Bd4+ 58.Kc4 b5+ 59.axb5 axb5+ 60.Kd3 Kc5




analysis diagram





Only a pair of pawns to go... How much time does Black have on the clock??

43...Kb4 44.Rh3 Ka3 45.Kf1 Kxa2

This is beginning to look not-so-good.

46.f4 Rd8 47.Ke2 a5 48.Re3 Bc5 49.Rf3 f5 50.Ke1 Rd4 51.Ke2 Ka3 52.Re3 Rd8 53.Rf3 Kb4 54.Rh3 Re8+ 55.Kd2 Re4 56.Rf3


56...a4 57.Kc2 a3 58.Kb1 Re2 59.Rh3 Bd4 60.Rd3 a2+ White resigned



"White had his chances" – a pretty good footnote to someone playing a "refuted" opening.

One Thousand Days

Today this blog reaches one thousand consecutive days of posting. We've covered a lot of ground since the first day, June 10, 2008.

From the first published analysis of Alonzo Wheeler Jerome's opening, to the latest games available, we've been there.

From the pipe dreams of having an article on 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ published in the well-respected magazine Kaissiber, to the far reaches of Jerome's Double Gambit seen as a Martian invasion, it has been fun to exercise imagination to its fullest extent.

Tournaments have been chronicled, history corrected, mysteries uncovered, and loose ends tracked down.

There have been a few interviews, not nearly enough.

The opening has faced skepticism and worse, as well it should, given its many refutations.

On the other hand, IM Lane (who I sometimes erroniously granted the GM title to in my references) has mentioned the Jerome Gambit in his columns at ChessCafe.com and more recently in his book The Greatest Ever Chess Tricks and Traps.

The Database of games (available to all readers) has grown from 950 to almost 23,500.

According to Google Analytics, the number of countries that readers have visited from passed 100 quite some time ago. Almost 1/4 of readers have stopped here 100 times or more. One-sixth of readers have stopped here over 200 times.

What is ahead for this blog for the next 1,000 days?

More of your games, I hope. I share mine because I am familiar with them, but I post readers' when I get them. Your games are often better.

I hope to post more historical research, more tournaments, more analysis... and maybe even finally get down to writing a book on the Jerome Gambit. Now that would be a challenge!

Awkward...



I was pleased with this game until I played it over afterward. Then I felt like someone who had given a nice speech which kept the audience's attention, only to discover after it was over that I had been up in front of everyone with a giant stain on my shirt or pants...

perrypawnpusher - Fendertele
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.0-0 Nf6 5.Nc3 Bc5


The Semi-Italian Four Knights Game.

6.Bxf7+

The Semi-Italian Four Knights Jerome Gambit.

6...Kxf7 7.Nxe5+ Nxe5 8.d4 Re8


This line was seen not-so-long-ago in my game against Frele.

9.dxc5 Kg8

9...d6 while it was still easy to play, was seen in perrypawnpusher - louarn, blitz, FICS, 2010 (1-0, 49).

Instead, 9...b6 also attacking the White c5 pawn right away, was seen in perrypawnpusher - catri, blitz, FICS, 2010 (1/2-1/2, 42).


Rybka has a third suggestion, 9...Qe7.

10.f4 Nc6

10...Nc4 was punished in Wall - Santiago, FICS, 2010 (1-0, 28) with 11.e5 Nh7 12.Qd5+ Kh8 13.Qxc4.

Rybka suggests the discrete 10...Nf7.

11.e5 Nh7


12.Ne4

I admit that I played 12.Qd5+ in perrypawnpusher - Frele, blitz, FICS, 2011 (1-0, 26) with the hope that Black would blunder with 12...Re6, but I had to find another way to win when he answered with the sensible 12...Kh8.

12...Nxe5

Nifty thinking: he returns the piece for two pawns and a roughly even game.

13.fxe5 Rxe5 14.Qd4 Qe8


Material is even, but White's c5 pawn continues to exert pressure on Black's game.

15.Ng3 Re1

Leading to trouble. Black should have challenged White's annoying pawn with 15...b6.

16.Bf4

After the game Rybka pointed out what I had missed, that 16.Bxh6 (linking White's Rooks like the text, but also grabbing a pawn and attacking Black's King) was much stronger. Then 16...Re5 would be answered by the simple 17.Bf4; while 16...Qe5 would see the Queen sac 17.Qc4+ Qe6 18.Raxe1; and 16...gxh6 would be crushed by the same 17.Raxe1.

16...Rxa1 17.Rxa1 c6


Saving the c-pawn, but emphasizing the cramp in his Queenside. Black would have done better to simply give up a pawn with 17...d6 18.cxd6 cxd6 to free his development.

18.Nf5 Qg6

A slip. However, I was so enamored with the positional strength of my next move that I totally missed a much stronger tactical move. 

19.Nd6

Owwww...

Everyone together: 19.Ne7+ would win the Queen!!

How awkward.

19...Ng5

Maybe my opponent saw what was coming, but he should have routed the Knight along a safer path: 19...Nf8 20.Re1 Ne6.

20.Bxg5 Qxg5 21.Re1


Black will lose a piece.

21...Kh7 22.Qe4+ Qg6 23.Qxg6+ Kxg6 24.Re8 a5 25.Rxc8


25...Ra7 26.Rc7 a4 27.Rxb7 Ra5 28.Rxd7 Rxc5 29.Ne4 Rxc2 30.Rd2 Rc1+ 31.Kf2 Rc4 32.Kf3 Kf5


Another slip, but this was my day to miss Knight forks. Sigh...

33.g4+ Kg6 34.h4 h5 35.g5 Kf5 36.Nd6+

Saw it this time. Consequently, Black resigned.

One Thousand Posts

This post marks a milestone, the 1,000th one to this blog.

It marks only 998 consecutive days of posting, however, as on two days in that span I posted twice. (For fun, figure out which two.)

The milestone of 1,000 consecutive days of posting will come the day after tomorrow.

In the meantime, what would make this blog better? Drop me an email or make a Comment below and let me know.

What I'd like:
a) to receive more games from readers, annotated if possible
b) to see analysis of readers' favorite variations
c) to receive a large data dump of Jerome Gambit / Blackburne Shilling Jerome Gambit / Semi-Italian Jerome Gambit / Italian Four Knights Jerome Gambit games from a site other than FICS, which I already have access to. The Database, now numbering over 23,3000 games (perhaps as many as 20k are FICS games), could easily increase by 25% - 50% - 75% if someone at ICC, Chess.com, RedHotPawn.com, ChessWorld.net or other sites could mine their databases and share the results. Pretty please?

Sometimes "Simple" is Better

When a player's position becomes difficult, he might seek complications, hoping that his opponent will lose his way, and then the game. In the following fight, however, the alternative strategy of not getting "too fancy" would have brought better results for my opponent.

perrypawnpusher - Eferio
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.0-0 Bc5 5.Bxf7+

The Semi-Italian Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ng6


8.Qd5+ Ke8 9.Qxc5 d6 10.Qe3 Ne5


An "in your face" kind of move. In this or similar positions I have faced it twice against Kotimatka (see "Diagnosis: Misplaced Knight" and "Echoes"), twice against mikelars (see "Rumors of My Death" and "Kick Me"), and once against Irhall (see "One Little Pawn").

11.d4 Nc4

Of course 11...Nc4 is not the only way to attack White's Queen. There is 11...Ng4 as in perrypawnpusher - Kotimatka, blitz, FICS, 2009 (1-0, 21)

12.Qd3 Be6


Black weaves a complicated defense for his Knight, avoiding the "simple" 12...Nb6.

13.d5 Ne5

Back again.

14.Qg3 Bd7 15.f4 Bb5


More complications. It was time to give material back and keep the loss to a pawn: 15...Ng4 16.h3 N4f6 17.e5 Kf8 18.exf6 Qxf6.

16.fxe5

Instead, 16.Re1 was good enough for advantage, as in 16...Nf7 17.e5, but I was perfectly happy to fall into Black's combination.

16...Bxf1 17.Qxg7 Qh4


If it were not for the White "Jerome pawn" at e5, Black could have defended with 17....Qf6, etc. Now he has to scare up some kind of counter-play, with the accent upon "scare".

18.Qxh8 Kf8 19.Kxf1 Qxe4


"Best" for Black was probably 19...Qxh2 but it held no promise for long-term survival. 

20.Bxh6+ Kf7 21.Qg7+ Ke8 22.Qxg8+ Kd7 23.Qf7+ Kc8 24.Qe8 checkmate

Pawns 1, Piece 0


Sometimes White wins by attack in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and sometimes he has to "play out" the game and use his pawns against his opponent's extra piece. Proper defense by Black should save at least half of the point, but that doesn't always happen...

perrypawnpusher - CorH
blitz, FICS, 2011

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



4...Kxf7 5.Nxe5+ Nxe5

Our earlier game, featuring 5...Kf8, was a pretty good example of Black and his extra piece out-duelling White and his extra pawns (although I had my chances)  perrypawnpusher - CorH, blitz, FICS, 2009, (0-1, 74).

6.Qh5+ Ng6 7.Qd5+

A check of The Database shows that I don't always play this "nudge": 7.Qxc5 d6 8.Qe3 Nf6 9.0-0 Re8, perrypawnpusher - MoonCat, blitz, FICS, 2007, (1-0, 29).


7...Ke8 8.Qxc5 d6 9.Qe3 Nf6 10.0-0 Kf7


Returning the extra tempo lost by the "nudge".

11.f4


Also seen: 11.Nc3 as in perrypawnpusher-joejox, blitz, FICS, 2009 (½-½, 27).

I did not find Rybka's apparent "let's not risk anything else" recommendation that it made after the game to be appealing: 11.d4 Re8 12.Qb3+ Kf8 13.f3 c6 14.c4 Qb6 15.Be3 Be6 16.Nc3 Bf7 17.Rfe1 






analysis diagram








11...Re8


Of course, Black's Knight can aways kick White's Queen instead, with 11...Ng4 as in perrypawnpusher - Feestt, blitz, FICS, 2009 (1-0, 19).

12.f5 Ne5


Instead, the precipitous 12...Rxe4 did not work at all after 13.fxg6+ hxg6 14.Qxe4 in perrypawnpusher - bnxr, blitz, FICS, 2011 (1-0, 29).


13.Nc3


I wanted to play 13.d4 but could not figure out how to meet 13...Neg4. The moves are from Vazquez -Carrington, Mexico, 2nd match, 1876 and I should have remembered them for historical reasons, if no others: 14.Qb3+ Kf8 15.h3 Rxe4 16.hxg4 Rxg4 17.Qf3 c6 18.Nc3 d5 19.Bf4 Kg8 20.Be5 h5 21.Rae1 Bd7 22.Re3 Qb6 23.b3 Rf8 24.Na4 Qb4 25.Nc5 Bc8 26.c3 Qb6 27.Bxf6 gxf6 28.Qh3 Rg5 29.Ne6 Bxe6 30.fxe6 Qc7 31.e7 Re8 32.Qe6+ Kh8 33.Qxf6+ Rg7 34.Qf8+ Black resigned

13...Kg8


Prudent. There was always the kick at the Queen with 13...Nc4 as an alternative, although it did not lead to much difference after 14.Qd4 Ne5 15.d3 Kg8 in perrypawnpusher - DysonLin, blitz, FICS, 2009 (1-0, 23).


14.d4 Neg4


Of course.

15.Qf3 Bd7


An opponent tried 15...c6 in perrypawnpusher - avgur, blitz, FICS, 2010 (1-0, 23) but the pawn probably needed to take two steps. 


16.h3 Nh6 17.Bxh6 gxh6 18.Rae1 Kh8


19.e5 dxe5 20.dxe5 Ng8



Active defense with 20...Bc6 (followed by 21...Rg8) was more likely to be successful in holding back the pawns, reaching  a balanced game.

21.f6 Bc6 22.Qf4 Rf8 23.f7



White's "Jerome pawn" threatens to win back the sacrificed piece: 23...Qg5 24.Qxg5 hxg5 25.fxg8/Q+ Kxg8. White would be a pawn better, but the win would be far off.

Instead, Black saves his Knight and loses his King.

23...Ne7 24.Qf6 checkmate

Lazy, lazy, lazy

I ran across the following game the other day, one that I played last year, that I had not presented on this blog.

No, it is not because I lost the game that it had slipped my mind. It is because how I won the game.

perrypawnpusher - maxmi
blitz, FICS, 2010

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


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


7.Qxe5 d6 8.Qg3

In an earlier game my opponent faced 8.Qf4+ Nf6 9.d3 Kg8 10.Be3 Bxe3 11.Qxe3 Bd7 12.Nd2 b5 13.d4 Qf8 14.0-0-0 Re8 15.f3 d5 16.e5 Nh5 17.Qb3 c6 18.Qa3 Ra8 19.Rhf1 Nf4 20.Rf2 Be8 21.h3 Bg6 22.Qa6 h5 23.Qxc6 Rc8 24.Qxd5+ Kh7 25.Qxb5 Qf5 26.Ne4 Qd7 27.Qxd7 Black resigned, piratebopper - maxmi, FICS, 2010.

8...Nf6 9.d3 Nh5

Played in a trio of internet games by belgje a number of years ago -- destinyx - belgje, GameKnot.com, 2004 (1-0, 80); obviously - belgje, GameKnot.com, 2004 (0-1, 19); and raes - belgje, GameKnot.com, 2004 (0-1,49) and more recently against a Jerome Gambit Gemeinde member, Petasluk - brittaundvolker, blitz, FICS, 2009 (1-0, 32).

10.Qf3+ Ke8

Reflex.

11.Qxh5+ g6 12.Qg5


Two pawns up, my brain dropped into L for Lazy: Why think when you can just push pieces? This is a habit that has hurt me in the past, so it is actually painful to see it be successful in this game.

12...Qxg5 13.Bxg5 Rf8 14.0-0 h6

This does not help, giving a free pawn. From now on I play almost on auto-pilot.

15.Bxh6 Rf7 16.Nc3 c6 17.Be3 a5 18.Bxc5 dxc5


19.f4 b5 20.Rae1 b4 21.Nd1 Bd7 22.Ne3 Ke7 23.Nc4 a4 24.Ne5 Rh7 25.Nxd7 Kxd7


Anyone still awake out there?

26.f5 gxf5 27.Rxf5 Rah8 28.h3 Kd6 29.Ref1 c4 30.d4 Re7 31.Rf6+ Kd7 32.Rf7 Rh4 33.Rxe7+ Kxe7 34.Re1 Kd6


35.c3 c5 36.dxc5+ Kxc5 37.e5 Kd5 38.cxb4 Re4

Unwittingly or wittingly bringing the game to a close.

39.Rxe4 Kxe4 40.e6 Ke5 41.e7 Ke6 42.e8Q+ Black resigned
