One More Time

Right now, the second largest group of readers of this Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) blog is from Brazil. I was therefore not surprised to find at the centraldoxadrez website the famous Blackburne game against the Jerome Gambit.

It's worth showing again (with notes translated from the Portugese) because it's such a fun game. Plus, it's a good reminder to those who play Black how to carry out the Blackburne Defense (see "Having said A...")


Jerome - Blackburne
London, 1890

The name of the player of the White pieces is an error: Alonzo Wheeler Jerome never visited London, nor did he ever get to play his favorite opening against him. I think the mistake began in one of Eric Schiller's books – I contacted him with a correction.


Also, the year "1890" is an odd slip. Blackburne refers to the game taking place "about 1880" in his Mr. Blackburne's Games at Chess (1899), although a contemporary source – the Brooklyn Chess Chronicle – gave the date as 1885.


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

As incredible as it seems, this madness has a name. It is the Jerome Gambit, played here by its author! Analysis of this line has appeared on the Internet. What idleness is capable of generating!

4… Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6

Blackburne did not want to be on the defense after 6… Ke6 7.Qf5+ Kd6, but even so the sequence 8.f4 Qf6! provides a great advantage to Black.

7.Qxe5 d6 8.Qxh8
White loses numerous tempos moving the Queen to capture the Rook. Meanwhile, Black mobilizes his pieces and looks to uses his enormous advantage in development.

8… Qh4

Threatening … Qxf2+ and defending the h7-pawn. In this way, the Queen has joined the attack without loss of time.

9,0-0 Nf6 10.c3?
The idea was to play 11.d4 cutting to the action of the Black Bishop along the c5-f2 diagonal. However, the correct move would have been 10.Qd8 that pins the Black Kinght at f6 and hinders the Black attack.

10… Ng4!

The Knight is brought into the attack. Black threatens … Qxh2 checkmate.

11.h3 Bxf2+ 12.Kh1
Or 12.Rxf2+ Qxf2+ 13.Kh1 Qf1 checkmate

12… Bf5!

Another Rook is sacrificed so that the Bishop quickly enters the game.

13.Qxa8
13.exf5 Rxh8 gains the Queen and the game.

13… Qxh3+! 14.gxh3 Bxe4 checkmate

Yesterday's post (see "A Question of Theory and Practice") referred to Hindemburg Melao, Jr.'s 2003 internet article at Superajadrez.com, with significant analysis of the famous Amateur - Blackburne Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game. I would like to point out that at about the same time as Melao, Catalan Master Richard Guerrero Sanmarti wrote an article for Ajedrez en Madrid on the Blackburne game, with equally relevant analysis, some of which I'd like to share. [Be warned, my Spanish translation skills are poor.] Stranger - Blackburne London, 1880[sic] 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+?

Absolutely impressive! ... but totally incorrect! 4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6! ...[I]t seems evident that 6...Ke6 was somewhat dangerous... it was also possible for Black to choose simple 6th move answers: 6...Kf8! 7.Qxe5 d6; or 6...Ng6! 7.Qxe5 d6? ...To sacrifice a Rook, it was far better to do it with 7...Qe7! 8.Qxh8 Qxe4+ 9.Kd1 (9.Kf1 Qh4! 10.g3 (10.d4? Bxd4 threatening captures on f2 and to the White Queen on h8) 10...Qh3+ 11.Ke1 (11.Kg1 b5! -+ followed by Bb7! and the Bishop captures on g2) 11...Qe6+ 12.Kf1 (12.Kd1 Qg4+ 13.Ke1 Qe4+ 14.Kf1 with a decisive advantage for Black (14.Kd1 Qf3+! 15.Ke1 Bxf2+ 16.Kf1 Bxg3+ 17.Kg1 Qf2#) ) 12...Nf6! -+ and the unprotected White King can not be saved from Black's imminent attack) 9...Qxg2 10.Qxh7+ Kf8 11.Re1 d5! -+ and Black has a decisive attack when adding the Bishop on c8 and the Rook on a8. 8.Qxh8 Qh4 9.0-0! Nf6 10.c3? ... 10.Qd8! +/- was essential and White not only defends but obtains a clear advantage. The keys of the play are the attack on c7, and the pin of the Black Knight on f6 that cannot now be added to the attack; the "natural" 10.d3? also was losing after 10...Bh3! 11.Qxa8 ( or 11.Qxf6+ Kxf6! 12.gxh3 Qxh3 with a winning position) 11...Qg4 12.g3 Qf3 10...Ng4! -+ The brilliant romantic Englishman will execute the extraordinary combination that he prepared with 6...g6! 11.h3 ...after 11.Rd1 Qxf2+ 12.Kh1 Qg1+! 13.Rxg1 Nf2# 11...Bxf2+ 12.Kh1 And now comes the skillful play that makes Blackburne's sensational finish possible. Clearly if 12.Rxf2+ Qxf2+ 13.Kh1 Qf1# 12...Bf5! A fantastic move! 13.Qxa8 To eat or be eaten. 13.exf5 Rxh8 -+ with checkmate in a few moves. 13...Qxh3+! 14.gxh3 Bxe4 A really spectacular checkmate!

A Question of Theory and Practice

"Theory" and "practice" in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can be light-heartedly summed up as: the leading theory is not to practice the opening.

Yet, we persist.

Today's game highlights an area of theoretical controversy – that is to say there would probably be a controversy, if enough people played the Jerome Gambit to be aware of it.

In typical Jerome fashion, White loses the theoretical battle, wins the game handsomely, nonetheless – while the rest of the world refines the 18th (or 28th) move of Sicilian Najdorf theory...

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

Munoz and Munoz wrote in the August 1885 Brooklyn Chess Chronicle

In the American edition of Cook's Synopsis K-K3 [...Ke6] is given as the best defence, but Mr. Blackburne's ingenious counter sacrifice in the present skirmish would seem to show that the text is at least as good.

7.Qxe5 d6

This move is usually given a "!" because the offer of Black's Rook led to a smashing finish in Amateur - Blackburne, London, 1885; but, in truth, it deserves a "?!". The best move, instead, is 7...Qe7!, Whistler's Defense, when the Rook is then truly poisoned.

After White captures the Rook in the current game, his biggest "risk" is in allowing Black chances to draw.

He should have attempted to free his piece by P to Q4 [d4] before castling.

9...Nf6 10.d4

I have not seen a lot of analysis of this move. The earliest entry in my database is from J. du Mont, in his 1942 200 Miniature Games of Chess, where he only notes that 10.d4 Bxd4 11.c3 would lead back to the Blackburne game. Certainly there must be earlier references.

Hindemburg Melao, Jr., in a 2003 internet article about the Amateur - Blackburne game, at superajedrez.com, mentioned that Idel Becker, in his Manual de xadrez (1974), attributed the move 10.d4 to Euwe, although he did not give the source. In any event, the author was dismissive

but in this case Black could simply follow with 10...Bh3 11.gxh3 (11.Qxa8 Qg4 –+ ) 11...Rxh8 12.dxc5 Qxh3 13.f3 g5 14.Rf2 g4 15.Bf4 (15.fxg4 Qxg4+ –+ )15...gxf3 16.Bg3 h5 17.Nd2 h4 18.Nxf3 Qg4 –+ ...

...The best option seems to be 10.Qd8 after 10...Bb6 11.e5 dxe5 12.Qd3 is not clearly how the Black people can be successful. For example 12...Bf5 13.Qb3+ (13.Qg3 Qxg3 14.hxg3 Bxc2µ) 13...Kg7 14.d4 Rd8 15.Nd2 (15.dxe5? Qxf2+! 16.Rxf2 Rd1#) 15...Qxd4 16.c3 (16.Nf3? Qxf2+!) 16...Qc5 with compensation for the material

10...Bxd4 11.Qd8

The game Glameyer - Piske, www.freechess.de, 2006, continued unsuccessfully 11.Be3 Ng4 12.Qxh7+ Qxh7 13.h3 Bxb2 White resigned.

In our game Black has walked by his chance for advantage, allowing White's Queen to both attack c7 and pin the Black Knight. Best for the second player at this point is 11...Bb6, although White's Queen can still be released with 12.e5 dxe5 13.Be3 (or 13.Qd3).

11...Bf5

Quickly losing the thread of the game.

12.Qxc7+ Bd7 13.Qxd6

White has his choice of ways to win now.

13...Bb6 14.e5 Ng4

This only looks dangerous.

15.Qxd7+ Kg8 16.h3 Bxf2+

An attempt to swindle: 17.Rxf2? Qxf2+ 18.Kh1 Qf1 checkmate!

17.Kh1 h5 18.Bf4 Black resigned

Another Krejcik

Recently Geoff Chandler ("greenpawn" at redhotpawn) posted an interesting Krejcik Gambit (1.e4 Nf6 2.Bc4) game at the RedHotPawn website. As that opening's just been touched upon here (see "I want my Jerome Gambit!") I thought I'd share it with readers. It features another relentless King hunt.

Thalassa - MHT

redhotpawn.com, 2004

1.e4 Nf6 2.Bc4 2...Nxe4 3.Bxf7+ Kxf7 4.Qh5+ 4...Kf6

This does not look any wiser than the 4...Ke6 of perrypawnpusher - computer, internet 2009. Better was either 4...Kg8 5.Qd5+ e6 6.Qxe4 d5 or 4...g6 5.Qd5+ e6 6.Qxe4 Bg7.

5.Qf3+ Ke5

Hanging onto the Knight! This is not as dangerous as 5...Kg5 6.Qf7 Nf6 7.d4+ Kf5 8.f3 h5 9.Ne2 h4 10.g4+ hxg3 11.Nxg3 checkmate, but; 5...Kg6 was to be preferred (although White still is better).

6.d4+ Kxd4

7.Ne2+

Interestingly, a bit better was 7.Nc3 Nxc3 8.bxc3+ Ke5 9.Nh3 with a serious attack. It's a position worth looking at.

"I want my Jerome Gambit!"

The other night I was spending time on my computer, when I decided to go to a website that I'd not visited before, and try out their chess wares. I was having no luck finding an opponent, so I quickly latched onto the resident computer program. I noticed that it was at its default setting, and decided to throw a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) at it.

Bad idea. The silicon warrior did not want to enter a Giuoco Piano, no matter how many times I took the White pieces. Furthermore, it kept insisting that I alternate playing Black. I had to make at least a few moves on defense: once I resigned as my first "move", only to find the computer the next game responding to my 1.e4 with "resigns." Silly computer...

I'd just about given up, and thought about going to bed, when the computer offered to play an Alekhine's Defense. Aha! At least I could go out with Jerome-ish play: I would try the Krejcik Variation!

Sources refer to this as the Krejcik Variation, although the only game I've been able to find by Josef Emil Krejcik, against the player Gottlieb in 1922, went 1.e4 Nf6 2.Bc4 d6 3.Nc3 Nxe4 4.Bxf7+ Kxf7 5.Nxe4 e5 6.Qf3+ Kg8 7.Ng5 Black resigned

2...Nxe4 3.Bxf7+ Kxf7 4.Qh5+



4...Ke6


The best defence for Black is supposed to be 4...Kg8 5.Qd5+ e6 6.Qxe4 d5, which seems quite playable for White to any Jerome Gambit player.

5.Qg4+ Kd5

The program foolishly holds onto its material. Certainly 5...Kf7 was an option.

Going for the quick knockout.

Later, Rybka 3 recommended: 6.Nf3 d6 7.c4+ Kc6 8.Qxe4+ Kd7 9.0-0 Qe8 10.d4 Kd8 11.Qe3 g6 12.Nc3 Bg7 13.Bd2 Rf8 with a White advantage.

There was also the dangerous (for Black) line 6.d3 Kc6 7.Qxe4+ d5 (7...Kc5 8.Be3+ Kd6 (8...Kb5 9.Nc3+ Ka6 10.Qa4#) 9.Bf4+ e5 (9...Kc5 10.Qc4+ Kb6 11.Nc3 a5 12.Be3+ c5 13.Qxc5+ Ka6 14.Qb5#) 10.Bxe5+ Ke7 11.Bxc7+ Kf7 12.Bxd8 +- ) 8.Qa4+ b5 9.Qa5 e6 10.a4 b4 11.Qb5+ Kd6 12.Nf3 Qf6 13.Qxb4+.

6...Kd4

Stubborn to the very end. Less painful was either 6...e5 7.Nf3 d6 8.c4+ Kc6 9.Qxe4+ Kd7 or 6...Kc6 7.Qxe4+ but both involved surrendering the Knight.

Again and again...

While it is true that the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can have quite an impact when it comes as a surprise, there are some players who are willing to play it again and again against the same opponent, as long as it leads to good results. Mrjoker, for example, has played the Jerome Gambit 16 times against his worthy opponent PhlebasP. Scoring over 80% so far, he is unlikely to give up the opening in their next clash.

Out of a clear sky...

In posts like "I apologize, Jerome Gambit" and "Diagnosis: Misplaced Knight" I have fussed and fumed about the kind of bother that Black's Knights can cause, even in main-line Jerome Gambits (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), so when I saw the following game, I thought I'd share it: for those who defend the Jerome, another annoying idea; and for those who play the Jerome, something to prepare for...

I have 29 games in my database with this position – almost 2/3 by Louis Morin ("mrjoker") – so, you see, lightning can flash out of a clear sky and strike even the best of the Jerome Gambit Gemeinde.

10.0-0 Ng4 A new move. Where should the Queen go?

Rybka 3.0 suggests the line: 11.Qg3 Rf8 12.Nc3 Nf6 13.d4 Nh5 14.Qe3 Nhf4 15.g3 Nh3+ 16.Kg2 Kf7 17.f4 with a small, but bearable, advantage to Black.

The move White chooses seems thematic (i.e. centralized and on the file opposite the un-castle-able King) in a harmless position.

11.Qe2 Qh4

Suddenly, things are very bad.

12.h3 Nf4 13.Qf3 Ne5

Annoying, yes?

White's response now loses his Queen, but Rybka 3.0 suggests that the "best" move was to give it up anyway with 14.Qxf4.

14.Qc3 Ne2+ White resigned

A lesson worth remembering.
