A GM Faces the BSJG: Not Quite (Part 2)

[continued from previous post]

In the previous post, I mused
Last year, on this blog, I had a lot of fun looking at the idea of a Grandmaster playing or facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), online or over-the-board... "A GM Faces the Jerome Gambit (Part 1 and Part 2) and "Jerome Gambit: More GMs? (Part 1 and Part 2)"... 
The other day I started wondering: Did any GMs play or face the Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+)? That search would be a different kind of task, as the game would have to feature either a rare example of a GM playing the BSG, or, even less likely, a GM playing the BSJG. But my curiosity was piqued... 
A search of The Database did not turn up any games with a player (of either color) rated 2500...

So, I next turned to my ChessBase "Big Database" (almost 6,5000,000 games), and did a search for the starting position of the Blackburne Shilling Gambit, below.

I was shocked to find 12 games where at least one of the players was rated 2500!

Closer examination, however, showed that all of the examples came from the Bird Variation of Ruy Lopez: 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nd4 4.Bc4.

Still searching, however, I checked the online ChessBase Live Database, looking for 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ games, and I came upon one with Ian Rogers playing Black.

Ian Rogers! I knew that name: Australian GM! Amazing!

Well, not quite. The game was played in 1975, a few months before Rogers turned 15, five years before he became an International Master, and ten years before he became a Grandmaster.

Let's look at the game, anyhow, as it is quite educational. 

Nater, Carl - Rogers, Ian
Begonia op 09th, Ballarat, 1975

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

Rogers, the teenager, is feeling frisky. I don't know much about his opponent, Carl Nater (age 35 at the time of the game), but a check on the FIDE website indicates that he had a rating of 1378, so, perhaps Black wished for a quick, trappy win.

Carl Nater, 80, at the 2018 Begonia tournament. He later played at the Victorian Country Championships in 2019. Recent word from GM Rogers is that Nater is still playing chess.

4.Bxf7+ 

This is the earliest game that I have with the Blackburne Shilling Jerome Gambit, predating - by 20 years - Melao Jr, H. - Danilo, Centro Cultural, 1996: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ Kxf7 5.Nxe5+ Ke6 6.c3 Kxe5 7.cxd4+ Kxe4 8.Qh5 Kxd4 9.d3 Bb4+ 10.Nc3 Bxc3+ 11.bxc3+ Kxc3 12.Qc5+ Kxd3 13.Qd5+ Kc3 14.Bd2+ Kb2 15.Qb3+ Kxa1 16.O-O#

4...Kxf7 5.Nxe5+ Ke8

The Database has 2,585 games with position, with White scoring 58%.

6.Qh5+ g6

If 6...Ke7, White would have a checkmate in 5, starting with 7.Qf7+.

7.Nxg6 hxg6 8.Qxh8 Nf6 



Nater opted to capture the Rook, instead of the g-pawn (with check), relying on the gain of material. 

Rogers skipped the wild 8...Nxc2+ 9.Kd1 Nxa1 10.Qxg8 Qg5 which might have given him an edge, opting, instead, for reasonable development.

Komodo 10 now sees the position as about even, with Black's piece balancing out White's 3 extra pawns. Black has a lead in development, but his King will be unable to castle.

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).

Research Mystery

Around 2003, Brazilian chess master Hindemburg Melão, Jr., wrote an article for the online chess site, SuperAjedrez, featuring Joseph Henry Blackburne's famous defeat of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+).

Today I can only trace the essay as far as an essay which is no longer available, which is unfortunate, as it contained some very interesting analytical and historical information, including [Note: my translation - RK]  
...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...
Although it is in conflict with the information given in Mr. Blackburne's Games at Chess (1899) – that the game in question was played "around 1880" – my preferred source for information on Amateur - Blackburne, London (see "Flaws" 1 & 2– the August 15, 1885 issue of the Brooklyn Chess Chronicle, edited by J.B. and E.M. Munoz – gives the year as 1885.

I would love to ask Senhor Melao about his sources, as he clearly has access to materials that I do not. (That would not be at all unexpected: Lt. S.A. Sorensen's seminal work on the Jerome Gambit, in the May 1877 issue of Nordisk Skaktidende, was subsequenly translated and reprinted around the chess world.)

For example, I have never seen the Blackburne game dated as having been played in 1868 – six years before Alonzo Wheeler Jerome published analysis of "his" opening in the Dubuque Chess Journal. Nor have I seen it reported as played in 1888 – the Brooklyn Chess Chronicle reported that it had been played "some months ago in London", highly suggestive of the year 1885.

As for the references to the game being played in Manchester and the naming of the Amateur as "Millner" – both were news to me as well. And: was it a blindfold game?

Is any reader familiar with the SuperAjedrez article?

Does anyone have acces to the Brazilian chess master, to pass on my questions? 

What a mystery!

A Not-So-Instant Victory

There is a line in the Blackburne Shilling Jerome Gambit where the Black King wanders far in search of adventure (and material). In the following recent game a capture seems to lead to an "Instant Victory", but things are not as simple as they appear.


kukkfive - Krait
standard game, FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4


The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6


6.c3 Kxe5 7.cxd4+ Kxe4


This looks even more dangerous for the King than 7...Kxd4. Best was the retreat 7...Ke6 8.Nc3 Kf7 when Black maintains an edge.

8.Qg4+

Is this the killer move? At one point (in one game), I thought so. Certainly a number of moves have been tried successfully, but that's not the complete story.

8.0-0 Qf6 (8...Nf6 was a better test, although White can continue with 9.Qf3+ with hopes for an advantage) 9.Qc2+ Kxd4 10.b4 Kd5 11.Bb2 Qg6 12.Qb3+ Kd6 13.Re1 b6 14.Be5+ Kc6 15.Rc1+ Kb7 16.Rxc7+ Kb8 17.Rc6+ Black resigned, fidotopdog - Krait, FICS, 2009;

8.d3+ Kxd4 (better was 8...Kd5 and after 9.Qb3+ Kc6 10.Qc4+ Kb6 White can do little more than continue checking and arrange a draw) 9.Be3+ Kd5 10.Nc3+ Ke6 11.Qg4+ Kf7 12.Qh5+ Ke7 13.Nd5+ Ke6 14.Nf4+ Kd6 15.Bc5+ Kc6 16.Rc1 Nf6 17.Be7+ Kb6 18.Qc5+ Ka6 19.Qa3+ Black resigned, Jeopar - Krait, FICS, 2009;

8.Nc3+ Kxd4 9.Qg4+ (9.Qf3 transposing to 8.Qf3 is the right idea, but White gets away with his move) 9...Ke5 (9...Kc5 was the way out) 10.d4+ Kd6 11.Bf4+ Ke7 12.0-0 Kf7 13.Qh5+ g6 14.Qd5+ Kg7 15.Ne4 Nf6 16.Nxf6 Kxf6 17.Bg5+ Black resigned, kingpro - Krait, FICS, 2009;


8.Qh5 Kxd4 (8...g5 is the right move for Black, forcing 9.Qf3+ Kxd4 10.Nc3 transposing to 8.Qf3) 9.d3 Bb4+ 10.Nc3 Bxc3+ 11.bxc3+ Kxc3 12.Qc5+ Kxd3 13.Qd5+ Kc3 14.Bd2+ Kb2 15.Qb3+ Kxa1 16.0-0 checkmate, Melao Jr.,H - Danilo, Centro Cultural, 1996;


8.Qf3+ (the best move for White) Kxd4 9.0-0 (instead, 9.Nc3 c6 10.Qe3+ Kc4 11.a4 and the mating net closing around Black's King will force him to give up his Queen one way or another) 9...Qf6 (after 9...Kc5 Black's King may be able to walk away from the battle, giving White only the opportunity to draw through repetition of Queen checks) 10.Qg4+(necessary was 10.Qe3+, winning) Kc5 11.Nc3 d5 12.Qa4 a6 13.b4+ Kd6 14.Bb2 c6 (moving the Queen to g6 avoids the now possible 15.Ne4+ although Black may still hold on with three pieces for his Queen after 15...dxe4 16.Bxf6 Nxf6) 15.Nd1 (this should lose) Qf4 16.Re1 Qe4 (a mouse slip, perhaps??) 17.Rxe4 Black resigned, GOH - kremba, FICS, 2009.

8...Kd5 9.Nc3+

Now, after 9...Kc6, as implausible as it seems, Black's King is secure. Even after 10.d5+ Kd6 the game is complicated, but even.

9...Kd6

What a difference a square makes!

10.Qf4+

After 10.0-0 I needed cooperation from my opponent to win in perrypawnpusher - MNUNP, blitz, FICS, 2009 (1-0, 18).

The strongest move here, tightening the net, is 10.Qe4.

10...Ke7

A slip. Better for Black (the move, the game) was 10...Ke6. Now things turn simply horrible for him.

11.Nd5+ Ke8 12.Nxc7+ Ke7 13.Nxa8 d6 14.0-0 Kd7 15.Qf7+ Kc6 16.d5+ Kc5 17.d4+ Kxd4 18.Be3+ Kc4 19.Rac1+ Kb5 20.Nc7+ Ka5 21.Qf4 Black resigned

Why, I oughta...

When I started writing this blog (not quite a year and a half ago), I decided to post every one of my Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf4+) and Jerome-related games, win or lose, good or bad. Three good examples of my bad play are perrypawnpusher - thehunterjames, FICS, 2009 (0-1, 25), perrypawnpusher -james042665, Chess.com, 2008 (0-1, 18), and perrypawnpusher - drewbear, JG3 thematic, chessworld, 2008 (0-1, 10).

The following game is not a loss, but in light of my experience with the Blackburne Shilling Gambit – especially the recent "Gorilla Chess", but also, for example "Keep the shilling..." – I sure looked pretty comical.

perrypawnpusher - MNUNP
blitz FICS, 2009

1.e4 Nc6 2.Nf3 e5 3.Bc4 Nd4


4.Bxf7+

Of course.

4...Kxf7 5.Nxe5+ Ke6

6.c3 Kxe5 7.cxd4+ Kxe4


Here I felt a little foolish. I knew that capturing the e-pawn was bad for Black (7...Kxd4 was roughly even), but I couldn't remember why, or how to prove it. Black should have thought of King safety: 7...Ke6 8.Nc3 Kf7 9.0-0 c6 10.d3 g6 11.Be3 Kg7 and if anyone has an advantage, it is the second player.

8.Qg4+

Okay, I not only didn't remember the right path, I didn't figure it out over-the-board, either.

The correct move was 8.Qh5, boxing-in the King, which Black should answer with 8...g5. Then a King-hunt starting with 9.Qf3+ either succeeds or allows White's Queen to get to e5 with check, followed by the capture of the h8 Rook.

An alternative to 8.Qh5 g5 was quickly dealt with: 8...Kxd4 9.d3 Bb4+ 10.Nc3 Bxc3+ 11.bxc3+ Kxc3 12.Qc5+ Kxd3 13.Qd5+ Kc3 14.Bd2+ Kb2 15.Qb3+ Kxa1 16.0-0 checkmate, Melao Jr.,H - Danilo, Centro Cultural 1996;
Or 8.0-0 Qf6 9.Qc2+ Kxd4 10.b4 Kd5 11.Bb2 Qg6 12.Qb3+ Kd6 13.Re1 b6 14.Be5+ Kc6 15.Rc1+ Kb7 16.Rxc7+ Kb8 17.Rc6+ Black resigned was fidotopdog - Krait, FICS 2009

8...Kd5 9.Nc3+ Kd6

This is very dangerous. The King should, instead, go to c6 when the game is still in balance.

10.0-0

I admit that I played this move with a sense of resignation: I wasn't sure what to do next, and figured that castling couldn't go too far wrong: I would have three pieces developed to his none (or one, if you count his King). 

Next time I'll know to play 10.Qe4. White can build a good attack on the dark squares after 10...a6 11.d3 g5 12.Qe5+ Kc6 13.d5+ Kb6 14.Be3+ c5 15.dxc6+ Kxc6 16.Qd5+ Kc7 17.Qa5+ and Black loses his Queen.




analysis diagram






Another way to play the position was 10.b3 Qe7+ 11.Ne2 Kc6 12.d5+ Kb6 13.d3 c5 14.dxc6 bxc6 15.Be3+ Kb7 16.Rc1 Qb4+ 17.Qxb4+ Bxb4+ 18.Nc3 Nf6 19.Ke2 Bxc3 20.Rxc3 Nd5 21.Rc4 Nxe3 22.fxe3 d5 23.Rb4+ Kc7 Black resigned, ibenrooked - ironhorse1056, GameKnot, 2005.

10...Nf6 11.Qf4+

Again, I told myself "the win has to be there" – but I couldn't find it. I'm not sure that it was there, any more.

11...Ke6 12.Re1+ Kf7 13.Nd5


13...d6 14.d3

Now Black can play 14...c6 and 15...d5 and be assured that he has weathered the attack. Instead, he gets careless (and not a moment too soon, as far as I was concerned).

14...Be7 15.Rxe7+

15...Kg8

If Black wanted to fight on, he needed to surrender his Queen for a Knight and Rook with 15...Qxe7.

16.Nxf6+ gxf6 17.Qg3+ Kf8 18.Qg7 checkmate


Perhaps it is true that "fortune favors the bold"!

Sources

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...

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.

My database has three examples of the recommendation, although none were available at the time this game was played: 9.d4 Nf6 ( 9...Bb4+ 10.c3 Qxe4+ 11.Kf1 Qd3+ 12.Ke1 Bg4 13.Qxh7+ Kf8 14.f3 Re8+ 15.Kf2 Qe2+ 16.Kg3 Bf5 17.Bh6+ Nxh6 18.Qxh6+ Ke7 19.cxb4 Qxb2 20.Qg5+ Kd7 21.Nd2 Qxd4 22.Rhe1 Rh8 23.Qe7+ Kc6 24.Rec1+ Kb5 25.a4+ Kxb4 26.Ne4 Rh3+ 27.gxh3 Qh8 28.Nf2 g5 29.Qe1+ Kb3 30.Qe3+ Kb4 31.Qd2+ Kb3 32.Qd5+ Kb4 33.Qb5 checkmate, perrypawnpusher - bakker, FICS, 2007; 9...Qxe4+ 10.Be3 Bxd4 11.Qxh7+ Kf8 12.0-0 b6 13.Bh6+ Ke8 14.Qxg8+ Kd7 15.Qf7+ Kc6 16.Qf3 Qxf3 17.gxf3 Bh3 18.Rd1 Re8 19.c3 Bc5 20.b4 Bxf2+ 21.Kxf2 Re7 22.Nd2 a5 23.a3 Rf7 24.Ne4 Bg4 25.Ng5 Rf6 26.Rd4 Kd7 27.Rxg4 d5 28.Rd1 c5 29.Rxd5+ Kc6 30.Rd8 axb4 31.axb4 cxb4 32.Rc4+ Kb5 33.Rxb4+ Kc5 34.Ne4+ Kc6 35.Nxf6 Kc7 36.Rd7+ Kc6 37.Be3 b5 38.Rd5 g5 39.Rbxb5 Black resigned, mediax - yorkypuddn ChessWorld.com, 2008) 10.Nd2 Bxd4 11.Rf1 Bh3 12.Qxa8 Bxg2 13.Qxb7 Bxf1 14.Qb3+ Ke7 15.Qg3 Qxg3 16.hxg3 Bg2 17.f3 Bh3 Black resigned, dj222 - invincible1,GameKnot.com, 2003

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!
