Jerome Gambit: Giving Black "A Second Chance"

You sit down to a game of chess, you are planing on using the Jerome Gambit - but your opponent opts to play the Two Knights Defense. What to do?

We have looked at this dilemma a number of times in the past (see, for example, "Jerome Gambit vs Two Knights Defense", parts 1, 2, 3 and 4).

The following game and its notes show that sometimes giving Black a "second chance" can return the game to desired channels. The focus is upon the games of a player who has dealt with this issue many times.

Wall, Bill - Guest165295

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6




4.O-O Bc5


Well, that's more like it. Black's Bishop comes to the party after all.

5.Bxf7+ Kxf7 6.Nxe5+

Bill has also tried 6.d36...Kg8 (6... Rf8 7. Nc3 Kg8 8. Bg5 h6 9. Bxf6 Qxf6 10. Nd5 Qg6 11. c3 d6 12. b4 Bb6 13. b5 Nd8 14. Ne7+ Kf7 15.

7.d4

The position is beginning to look like a "regular" Jerome Gambit position, if we go ahead and now add 7...Bxd4, transposing, i.e. 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 Nf6 8.0-0

Black could also have tried 11...d5 12.Nc3 c6 13.Bg5 Kf7 14.Rae1 Rf8 15.Re2 Kg8 16.Rfe1 Bf5 17.f3 Qd7 18.g4 Nxg4 19.fxg4 Bxg4 20.Re7 Nxe7 21.Rxe7 Qf5 22.Qxg7 checkmate, Wall,B - Mydrik,M, PlayChess.com, 2015.

12.Nc3 c6 13.Be3

White develops and hopes to take advantage of Black's King's position. "Objectively" Black is still better, with a piece for a pawn; but the d-pawn blocking the Bishop which hems in the Rooks is always an ominous sign...

13...Ne5

Instead, 13...Qe5, looking to exchange Queens and reduce the danger of an attack on his King, might have been more prudent.

14.Rae1 Neg4

Black is spending too much time moving the Knight. Perhaps he can not find a plan of play. Stockfish 8 gives a subtle line that leads to an advantage (a pawn) for White, but which has plenty of play (Black has Bishop vs Knight and more central pawns): 14...b6 15.Bf4 Qxc5 16.Qxc5+ bxc5 17.Rxe5 Kf7 18.Rxc5 Re8 19.Be5 Bb7 20.Bxf6 Kxf6 21.f3 d6 22.Ne4+ Ke7 23.Rh5 h6 24.Rd1 Rad8 25.Ra5 a6 26.Kf2 c5 27.c3 g6 28.h3 Rf8 29.Nd2 Rf6 30.Nc4

15.Bf4

The benefit of pursuing development while the opponent dithers. White's Bishop not only exposes a Rook attack on the enemy Queen, it eyes the fantastic d6 square.

15...Nd5

The simplest response - 15...Qf7, withdrawing the Queen to a safe square - is the best, although then White would have the powerful 16.Bd6+ as a reply. In the excitement, Black seems to have forgotten about Her Majesty.

16.Nxd5 cxd5 17.Rxe7 Black resigned

History Clouded



In Mr. Blackburne's Games at Chess (1899), the notorious Jerome Gambit game Amateur - Blackburne was given as "played at Simpson's Divan about 1880."

I have questioned the date that Blackburne gave - See "Flaws (Part I)" - as the August 15, 1885 issue of the Brooklyn Chess Chronicle (J.B. and E.M. Munoz, editors) presented the game as having been "played some months ago" which would suggest that it was played during 1885, but not likely in July or August of that year.

It now looks like I will have to back off from my correction, and add even more uncertainty to the date of the game.

Tim Harding's Joseph Henry Blackburne A Chess Biography (2015) - which, as I have noted, does not give Amateur - Blackburne - shows that the British master left for Australia in December 1884, and spent the first half of 1885 "Down Under". A return home was short-lived, as there was an important tournament to participate in
Blackburne and son apparently disembarked at Plymouth on 4 July. As the ship was only docked at Gravesend on the fifth, they must have come up to London by express train. Every day counted, the first round in Hamsburg being on 12 July. After less than a week in England, Blackburne was off on his travels again. 
The Hamburg tournament ended July 27, wherupon Blackburne went to Hereford for the Counties Chess Association Masters tournament, which started August 3.
The events of 1885, therefore, do not appear consistent with the Brooklyn Chess Chronicle admittedly casual dating.

It is possible to extend Munoz and Munoz's "some months" further back in time and look for Amateur - Blackburne in 1884, although there are difficulties in this, too. Harding notes
Blackburne's mid-career health breakdown began before Christmas 1883 when he was forced to cancel all his engagements.
In an age "long before antibiotics or even aspirin and other effective medicines", Blackburne was quite ill.
In late April or early May [1884] he resumed playing at the [Simpson's] Divan; some casual games are preserved from that period...
However, his participation in Simpson's handicap tournament in the spring was affected by his "unfortunate illness" and it is worth noting
[T]he Morning Post, 30 June 1884, said that Blackburne's illness had "left him in a weak state of health, and has prevented him for several months from pursuing his avocation."
Although he travelled to Glasgow the last week in July 1884, it does not appear that his full health returned before his trip to Australia.

Unless I guess "late April or early May" 1884 (above), then "about 1880" (from Blackburne's book) will be as "precise" as I will be able to date Amateur - Blackburne, until another chess column, magazine, or book reference surfaces; especially if we recall the uncertainties mentioned by Brazilian chess master Hindemburg Melão, Jr. in his article for the online chess site, SuperAjedrez,
...Some sources indicate year of the game as 1868, others indicate 1888, and others indicate 1880. Some sources affirm that it was played in Manchester, others in London. Normally the name of the adversary is not given, having only "NN" or "Amateur", but in at least one source "Millner" is indicated as the name. Also it is not known if it was an individual game or part of a simultaneous display... [T]he game deserves to be cited as one of most beautiful pearls of blindfold Chess...

The Best Jerome Gambit Game of the Year (Part 2)


We continue from the previous post, considering a game that has lept to the top of the heap for Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games this year.


As indicated, Readers are encouraged to dispute my assessment by sending in other great Jerome Gambit games...


Wall, Bill - Guest871838

PlayChess.com, 2014



8.Qxh8 


Of the offer of the Rook with 7...d6, Blackburne wrote in Mr. Blackburne's Games at Chess (1899), "Not to be outdone in generosity." The cost to White of taking the Rook is to have his Queen locked out of the action, at a time when Black's pieces begin to swarm the Kingside.


Blackburne's book also contained the following: "NOTE. I used to call this the Kentucky opening. For a while after its introduction it was greatly favoured by certain players, but they soon grew tired of it."


A resonable explanation of the reference to the "Kentucky opening" has appeared previously in this blog (see "A New Abrahams Jerome Gambit" for a summary). 


As for the "certain players" who "greatly favoured" the Jerome Gambit, it is difficult to identify them by games played, as I have discovered the games of only a dozen or so players (other than Jerome, himself) who played the opening between when it was introduced in 1874 and the publication of Blackburne's book in 1899. Andres Clemente Vazquez, of Mexico, has four games in The Database, while E.B. Lowe, of Great Britain, has three.


Blackburne might well have been referring to authors who included analysis of the Jerome Gambit in their opening books, in which case George H.D. Gossip, of Theory of the Chess Openings (1879) and The Chess Player's Vade Mecum (1891) ; William Cook, of Synopsis of Chess Openings (1882, 1888); E. Freeborough and C. E. Rankin of  Chess Openings Ancient and Modern (1889, 1893, 1896);and Mortimer of The Chess Player's Pocket book And Manual of the Openings (1888 - 1906); are all likely suspects. Certainly, more research is still needed.


8...Qh4


This is Blackburne's counter attack, threatening 9...Qxf2+ 10.Kd1 Bg4 mate.


9.O-O


Munoz and Munoz, in their notes to Amateur - Blackburne, London, 1885, in the Brooklyn Chess Chronicle, suggested "He should have attempted to free his pieces by P to Q4 [d4] before castling." 


The move 9.d4 received a good look in "Updating the Jerome Gambit (Part 1)", including references to L. Elliot Fletcher’s energetic Gambit’s Accepted (1954), an internet article on Amateur - Blackburne (not currently available) by Brazil's Hindemburg Melao, and some musings and analysis from Bruce Pandolfini, in his 1989 Chess Openings: Traps & Zaps !


9...Nf6


The door closes on White's Queen.


10.Qd8


Melao mentioned that Idel Becker, in his Manual de xadrez (1974), attributed the move 10.d4 to Euwe (source not mentioned). Melao was skeptical about the move, giving Black’s counter-attack 10…Bh3 11.gxh3 Rxh8 12.dxc4 Qxh3 13.f3 g5 14.Rf2 g4 15. Bf4 gxf3 16.Bg3 h5 17.Nd2 h4 18.Nf3 Qg4 with advantage for Black. He preferred 10.Qd8 - another suggestion (without further analysis) by Munoz and Munoz in the Brooklyn Chess Chronicle, August 1885, who opined "The only hope he had was 10.Q to Q8 [10.Qd8], thus preventing the deadly  move of Kt to Kt5 [...Ng4]."


Bill Wall mentioned that 10.d3 loses to 10...Bh3 11.Qxa8 Qg4 12.g3 Qf3 as was brutally demonstrated in RevvedUp - Hiarcs 8, 2 12 blitz, 2006 (0-1, 12).


10...Bd7


Most consistent for Black is 10...Bb6, covering the c7 pawn and enforcing the embargo on the Queen. White should return a pawn to free Her Majesty with 11.e5 dxe5 12.Qd3 as in Wall,Bill - Foo,Nathan, Palm Bay, FL, 2010 (1-0, 33).

Updating the Blackburne Defense (Part 1)


Chess players who know about the Jerome Gambit are most familiar with the game Amateur - Blackburne, London, 1885. Many believe that the Blackburne Defense, when played properly, leads to an advantage for the second player.

Players a bit more familiar with the Jerome Gambit and past published analysis might well believe that White has the advantage.


Readers familiar with this blog would know that modern analysis has termed the Blackburne Defense as difficult, but actually a draw.


I thought of all of this as I played my most recent game, and decided that the Blackburne Defense needed another update.


Of course, you can start first with earlier efforts: "Update: Old Dog Can Still Bite", "A Closer Look (Part V)", "Update: Blackburne Defense" and "Junk Openings".

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6




Here is the famous Blackburne defense, from Amateur - Blackburne, London, 1885. The Brooklyn Chess Chronicle (edited by J.B. and E.M. Munoz) Vol. III, August 15, 1885, p. 169, noted the game was

"played some months ago in London between Mr. Blackburne and an Amateur..."
8.Qxh8 Qh4


Here Amateur played 9.0-0. The editors of the Brooklyn Chess Chronicle suggested
He should have attempted to free his pieces by P to Q4 before castling. 
Although my opponent lfcanales played 9.0-0 as well, I would like first to look at the under-investigated 9.d4. After all, if 9.0-0 leads to a draw, as Chandler and Dimitrov have argued, then 9.d4 might be the better chance for White to fight for an advantage.

Here is some of what I have found.


After 9.d4, thematic and best for Black is 9...Nf6, although other moves have been played.


For example, Black has the alternative 9...Qxe4+ 10.Be3 Qxg2 -best - there have been several games with lesser 10th moves:

Black can also respond to 9.d4 with 9...Bb4+ 10.c3 Qxe4+ (not 11.Kf1? from perrypawnpusher - bakker, blitz, FICS, 200711.Be3 Qxg2 12.Qxh7+ Kf8 13.Rf1 when White will hold on and keep his advantage.


10.Nd2 Bxd4 11.0-0


Given by Hindemburg Melao, in an internet article  at www.superajedrez.com, (which identified Blackburne's opponent as "Millner") as good for White. 


Instead, 10.dxc5 was given in Chess Openings: Traps and Zaps, by Bruce Pandolfini (1989) - see""Traps and Zaps" -  10...Qxe4+ 11.Be3 Qxg2 12.Rf1 where he wrote

Scenario: Don't be misled by White's extra Rook. It's a meaningless ornament. White is in serious trouble. His King is exposed and his cornered Queen is in danger of being trapped. The cruncher is 12...Bh3 which wins White's Queen by discovery from the a8-Rook.
Actually, the correct response to 11...Qxg2? is 12.Nc3!? which later prevents Black's Knight from moving to e4 and giving mate. After  12...Qxh1+ 13.Kd2 Qxa1? White turns the tables with 14.Bd4! (13...Qxh2 would keep Black's Queen in play) when Black's extra Rook would mean little in the face of White's strong counterattack.

Also, 10.e5 does not appear as strong as 10.Nd2 - and seems more dangerous for White - after 10...dxe5 11.Nd2 (11.dxc5? Qe4+; 11.dxe5?? Qxf2+ 12.Kd1 Bg4 mate) Bxd4 12.0-0 Be6!? 13.Qxa8 Bd5 14.Qc8 Ng4 15.Qxc7+ Ke6 16.Nf3 Bxf3 17.Bf4 Bxf2+ 18.Kh1 exf4 19.Qxf4 g5 20.Qb8 Be2 21.c4 Bxf1 22.Rxf1 Nf6 23.Qc8+ Ke5 24.Qxb7 Ne4 White has an edge, analysis by Houdini.

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...

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.

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

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.

White has his choice of ways to win now.

This only looks dangerous.

Alas, it was not meant to be...



The March 1891 issue of The International Chess Magazine carried news of a 6-game match in Havana, Cuba between Joseph Henry Blackburne and Andres Clemente Vazquez, from March 5 to March 11.


Vazquez, current Mexican Consul General in Cuba, was an early advocate of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). The past and future Mexican Chess Champion's handicap game in 1876 against Giraudy was introduced in the November 1876 issue of the American Chess Journal with some fanfare


Odds givers will also find the Jerome Gambit a summary method for disposing of the neophyte. And by the way, we observe that this new opening has found its way to Mexico – An American idea in the halls of the Montezumas. Signor Andres Clemente Vazquez, the Mexican Champion and editor of La Estrategia Mexicane, has been trying the "Double" [Jerome's Double Gambit] on an amateur at the odds of Queen's Rook, and that, too, with brilliant success, as will be seen by the following game, which we copy from La Estrategia.

In 1876 Vazquez was 3-0 with the Jerome Gambit in his second match against William Harrington, games he included in his book of that year, Algunas Partidas de Ajedrez.


Of note is that in his third edition of Analisis del juego de ajedres (1889) Vazquez included (along with the Giraudy game and a Harrington game) analysis of Blackburne's 1885 crushing defeat of the Jerome Gambit played by an amateur (for the game, see "Nobody expects the Jerome Gambit!", "Flaws (Part I)" and "Flaws (Part II)").


After 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6 8.Qxh8 Qh4 9.0-0 Nf6 in the Blackburne game, Vazquez suggested that instead of 10.c3 White should have played 10.Qd8, and after 10...Bb6 11.e5 dxe5 12.Qd3 White would have had the better game. (This is the earliest incidence of this analysis that I have seen; Munoz and Munoz, in reporting the Anonymous - Blackburne game in the August 1885 Brooklyn Chess Chronicle, had simply suggested 10.Qd8)

So, in the 4th game of the Blackburne - Vazquez match, with The Black Death leading two games to one, Vazquez had the White pieces and played: 1.e4 e5

In the second game of the match Blackburne had dodged with 1...c6, a Caro-Kann.

2.Bc4 Nc6

Best authorites recommend here 2...Nf6 wrote Steinitz.

3.Nf3 Bc5

The Italian Game! And now... and now... the Jerome Gambit???

And now Vazquez moved 4.0-0 and played a delayed Evans Gambit after 4...Nf6 with 5.b4.... He was checkmated in 40 moves.

The position after the third move again arose in the 6th game, with Blackburne leading the match 4-1, and Vazquez transposed to the pacific Four Knights Game with 4.0-0 Nf6 5.Nc3, losing in 33 moves.

Alas, a Jerome Gambit game was not to be.


(It is interesting to note that Mr. Blackburne's Games at Chess, published in 1899, has the more straight-forward move order for the 4th match game: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5, etc. On the other hand, P. Anderson Graham, in his summary of "Mr. Blackburne's Successes" in the same book, refers to Vazquez as the champion of Brazil!)

Harried

The (in)famous historical Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, Amateur - Blackburne, London 1885 featured a harried White Queen that captured one Rook on a diagonal and another by sliding across a rank – only to watch her King be checkmated across the board.


The following game, from the current Chessworld Jerome Gambit Thematic Tournament, features two of the top players and highlights a harried Black Queen shuttling forward and back, until her own demise.

5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6

White reaches an interesting position, historically. Here "Amateur" played 8.Qxh8 and after 8...Qh4 9.0-0 Nf6 10.c3 he was crushed by Blackburne: 10...Ng4 11.h3 Bxf2+ 12.Kh1 Bf5 13.Qxa8 Qxh3+ 14.gxh3 Bxe4 checkmate.
At that time, 10.Qd8 was suggested by J.B. and E.M. Munoz, giving White the better game; although, almost 120 years later, Chandler and Dimitrov showed that Black could hold the draw.

Throughout this tournament stampyshortlegs has shown a good understanding of the Jerome Gambit. Will he "fall into" and become a victim of Blackburne's "trap" – will he grab the Rook and ask his Queen to fight her way out, "risking" a draw in the process – or has he come up with an improvement, himself?

There's a pawn to be taken.

White has three pawns for his piece, but with Black's King not under attack, and with White's pieces not developed, the position has to be judged better for the second player.

Traps and Zaps


It's always fun to see where the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) turns up. Most recently, it was in IM Gary Lane's latest book (see "The extraordinary and forgotten Jerome Gambit"), but 20 years ago it was in Bruce Pandolfini's Chess Openings: Traps and Zaps.
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6

A defense made famous by Joseph Henry Blackburne (see "Nobody expects the Jerome Gambit!" and "Flaws (Part II)") and most recently explored on this blog in "Jerome Gambit: Drilling Down" (3), (4), (5), (6), (7), (8), (9) and (10).

8.Qxh8 Qh4 9.d4


An improvement suggested by Munoz and Munoz in the August 1885 Brooklyn Chess Chronicle, repeated by Fletcher in Gambits Accepted (1954) and Druke in the November 1987 Gambit Revue, to give some early citations. (Actually, the move is rarely mentioned, but see "A Closer Look (Part V)".)

9...Nf6

Druke gave this move as an alternative to Fletcher's 9...Qxe4+ 10.Be3, saying that it came from analysis by Fritz 5. Of course, the two lines can transpose; in either case, as Hindemburg Melao, Jr., wrote in an intenet article (2003) on Amateur - Blackburne, London 1885 (not currently available), White's proper response is Nd2.

10.dxc5


Pandolfini appears to be the first to explore this move, and he uses it in a bit of a morality tale (after a few more moves) about grabbing material in his Chess Openings Traps and Zaps.


10...Qxe4+ 11.Be3 Qxg2 12.Rf1




Scenario: Don't be misled by White's extra Rook. It's a meaningless ornament. White is in serious trouble. His King is exposed and his cornered Queen is in danger of being trapped. The cruncher is 12...Bh3 which wins White's Queen by discovery form the a8-Rook. If White tries to save the Queen by capturing the Rook, 13.Qxa8 then 13...Qxf1+ 14.Kd2 Ne4 is mate.

Interpretation:
White began with a very aggressive, sacrificial line of play which, because of Black's cavalier pawn move (6...g6), led to the gain of material. The price White had to pay was the removal of his Queen from the center of the board. Without his Queen being available for defense, White has to play carefully, and every move becomes critical. Instead of his h1-Rook, he should be more concerned with the potential trap of his Queen. The correct response to 11...Qxg2 is 12.Nc3 which later prevents Black's Knight from moving to e4 and giving mate. After 12...Qxh1+ 13.Kd2 Qxa1?(13...Qxh2 keeps Black's Queen in play), White turns the tables with 14.Bd4!. Black's extra Rook then means little in the face of White's strong counterattack.
