Hey! Wait! Oh, Never Mind...




I've probably spent way too much time fussing about a comment by Fat Lady at redhotpawn.com, referring to a chess game where Alexander Alekhine reportedly defended against a Jerome Gambit - see "Much Ado About... Nothing" - no doubt it is as much an "urban legend" as the CIA killing Marilyn Monroe or Elvis Presley being in a witness protection program.

The other day I ran into a simultaneous exhibition game by Alekhine, however, and I wondered: could Fat Lady have been thinking about a "reversed" Jerome?? Here we go again...

Alexander Alekhine - Alfred Berman

This is reminiscent of an offshoot of the "Blanel Gambit" in the Vienna or Bishop Opening, only reversed. For reference:

Interesting game.

Then, I realized that Fat Lady said "Alekhine played Ke6 and then held onto both pieces", which doesn't sound like a reversed Jerome Gambit, at all. Bummer.

I don't know, maybe he was mis-remembering the internet contest blackburne - AAlekhine, Chessworld, 2007!

A Propos the Blackburne Shilling Gambit


The opening 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4!? has been named the Blackburne Shilling Gambit, even though examples of Joseph Henry Blackburne playing the line have yet to turn up. Supposedly he would play off-hand games with amateurs for a shilling's stake, and such a trappy line might well speed up the master's collections.

Related to the latter, I enjoy sharing the following, from "The Chess Player" column of Yenowine's News for October 13, 1889. 

Our Milwaukee Chessist Abroad

J. L Garner, who is back from a five months' tour over Continental Europe, has been devoting his spare hours since his return to dealing out bits of precious chess gossip pertaining to his adventures among the chess lions of the Old World. All in all, he managed to win considerably more than half the games. In Paris he played two with Taubenhaus, drawing one. All the big guns were in London during his stay there, and the Milwaukeean met Blackburne, Bird, Mackenzie, Muller, Gossip and a lot of other stars at Simpson's Divan daily. He made even scores with Gossip, winning one, losing one and drawing one. He regards Gossip as below either Elliott or Treichler as a chess player. With Lee, a very strong player ,who beat both Burn and Blackburne, at the Bradford tournament, Garner had a peculiar experience. In one game he mated Lee on the move, and thinking he would not object, offered to let him take the move back. He was fooled in the man, however; he was willing enough to let the game count, and coolly pocketed the shilling which the professionals charge for a "lesson." As a rule, the chess professionals in London and Paris are a dilapidated lot of tramps, with coat sleeves out at elbows, toes projecting from their boots, hats badly caved in and a ghoulish eagerness to fasten upon some wandering amateur, and bleed him at the rate of a shilling a game...

Debut Vazquez


Here are two selections from the British Chess Magazine, from the January and February 1892 issues, concerning Andres Clemente Vazquez, an early member of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Gemeinde, recently spotlighted on this blog for his 1891 match with J.H. Blackburne (see "Alas, it was not meant to be").

Senor A.C. Vazquez, in La Strategie, says that after ten or fifteen years of conceding odds in Mexico, he as acquired some practice of the game. Experience has showed him the necessity of avoiding the exchanging of pieces from the commencement of the game, until, in short, the inferior player commits himself. The following variation, he believes, fills the bill. With it he has accomplished excellent results in Havana. It was designated by the late Captain Mackenzie, a "Terrible Opening."

(Remove White's Queen Knight)
1.c3 e5
2.Qc2 d5
3.d3 Nf6
4.Bd2 c5
5.0-0-0 Qa5
6.Kb1 Nc6
7.h3 Be6
8.e3 Be7
White proceeds 9.g4.

Variation :–
5...Nc6 6.f4 Bd6 7.g3 0-0 8.e4 Qc7 9.f5, &c.

In both cases, says the writer, White has a good position for attack, always reckoning the inferiority of the opponent. The "Debut Vazquez" is singular in this, that on [sic] matter what Black plays, White can always make the first five moves given above. Senor Vazquez hopes that the masters will analyze this opening and make their opinions known – Baltimore Sunday News




In our January number it was stated (p.11), on the authority of the Baltimore Sunday News, that the first player, conceding the odds of Q Kt, can always make the five following moves, whatever Black may reply :– 1.c3, 2.Qc2, 3.d3, 4.Bd2, 5.0-0-0. "East Marden," however, suggests for Black :– 1.e6, 2.Qf6, 3.Bc5, 4.Qxf2+ (no castling for White now!), 5.Qxf1, 6.Qxg2, 7.Qxh1! and White's game is hopeless. Senor Vazquez, who proposes the opening, would of course alter his tactics at the fourth move to avoid the impending catastrophe. All that is asserted is it is incorrect to say that the five moves can in all cases be played.

Mackenzie's chess column



[diagrams added, notation changed to algebraic]


...The Australian game which we print to-day is somewhat lengthy, but it is full of interesting points, and is well worth playing over, were it only from the fact that it is the only partie on record, we believe, in which the Jerome gambit is adopted in a correspondence game...

Chess in Australia
We are indebted to the Adelaide Observer for the subjoined interesting game. It was played recently by correspondence between Messrs. Charlick and Mann, two of the leading amateurs in Australia.

The Adelaide Observer

CHESS IN SOUTH AUSTRALIA
(From the Melbourne Leader.)

The following fine game is one of those in the closely contested match by correspondence to which we lately referred, between Messrs. Charlick and Mann. The time occupied in playing it was six months. It abounds in interesting and difficult positions. Another game has since been finished ending in a draw, making the score - Charlick 4, Mann 3, drawn 6.

[Since, Mr. Mann has won a game, making the score perfectly even. - Mackenzie]

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



This ingenious sacrifice was invented by Mr. Jerome, an American player, in 1874, and, unless correctly answered, yields a strong attack. It seems rather rash to venture on it in a correspondence game - Mackenzie

4...Kxf7 5.Nxe5+ Nxe5

5...Kf8 is, we think, better - Mackenzie

6.Qh5+ Ng6

6...Ke6 is preferable - Mackenzie

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 


The authorities give 9.Qc3 but White prefers the text move - Mackenzie

9...Nf6 10.d4 Qe7



10...Kf7 is surely stronger, bringing his R in to immediate action, and threatening to take KP with Kt - Mackenzie

11.0-0 Ng4

This only assists White in developing his game by driving back the Kt presently; 11...b6 seems the best method of getting his forces into action - Mackenzie

12.Qe2 Qh4 13.h3 Nf6 14.f4


White has now a most formidable attack - Mackenzie

14...Nh5 15.Qf2 Qxf2+ 16.Rxf2 Rf8 17.f5 Ne7 18.c4 c6


Again we should have preferred 18...b6 - Mackenzie

19.g4 Nf6 20.Nc3 d5 21.e5


White's pawns now look quite irresistable - Mackenzie

21...Nd7 22.cxd5 Nxd5 23.Ne4 N7b6 24.b3 a5 25.e6 

This, we believe, is premature. 25.Bg5 is a very strong move - Mackenzie

25...h6 26.Bb2 Ke7 27.Re1 Ra7


Black's game is so cramped that defeat is inevitable - Mackenzie

28.Nc5


White might also have obtained a fine game by advancing the KRP here - Mackenzie

28...Na8 29.Nd3 b5 30.Ne5 Kd6 31.Rc1 Ra6 32.Rc5 Bb7 33.Rfc2 Rc8 34.Bc1 a4 35.b4

Very well played - Mackenzie

35...a3

Had he taken P with Kt, White would have gained a winning position by 35...Nxb4 36.Bf4 - Mackenzie

36.Bd2 Nab6 37.Be1 Na4

Mackenzie passes over this move without comment, but Rybka suggests that it is a serious error, suggesting that instead 37...Nc4 38.Nxc4+ bxc4 39.R2xc4 Raa8 40.Rc1 g6 41.Bh4 Ra4 42.Rb1 Rg8 43.Bg3+ led to an even game.

38.Bg3

Likewise, Rybka suggests that this gives Black a slight edge, preferring 38.Ng6 Nf4 39.Bg3 Kc7 40.Rxb5 Kb8 41.Bxf4+ Ka7 42.Ra5 Nb2 43.Ne7 Re8 44.Nxc6+ and White is winning.

38...Ke7 39.Nd7 Nxc5 40.dxc5 Rg8 41.Bd6+ Ke8 42.Rd2 Ra4


This, we believe, is his best play; had he moved 42...Nf6 White could have replied with 43.Be5 forcing the game in a few moves.; If 42...Nxb4 White wins off-hand by 43.f6 - Mackenzie

43.Rxd5

Well played, obtaining a winning position, through it still requires great care to bring about that result - Mackenzie

43...cxd5 44.f6 gxf6 45.Nxf6+ Kd8 46.e7+

Rybka prefers capturing the Rook.

46...Kc8 47.Nxg8 Bc6 48.Nf6


Rybka sees this as a serious error, leading to an advantage for Black, preferring 48.Nxh6 Rxb4 49.g5 Rb1+ 50.Kf2 Rb2+ 51.Kg3 Be8 52.c6 Rxa2 53.Nf5 Bxc6 54.g6 d4 with a roughly equal game.

48...Rxb4 49.e8Q+ Bxe8 50.Nxe8 Rb1+ 51.Kf2 Rb2+ 52.Kf3 Rxa2 53.Nc7
White is in a bad way, and it is only Black's next two inaccurate moves that bring the game back in his favor.

53...b4 54.Nxd5 b3



55.c6 Rc2



(must) - Mackenzie

56.Bxa3 Ra2 57.Bd6 Rc2 58.Be5 b2 59.Nb6+ Kd8 60.c7+ Rxc7 61.Bxb2 Rc5 62.Bd4 Rb5 63.Nc4 Ke7


64.h4 Ke6 65.Ke4 Rb1 66.Ne3 Kf7 67.h5 Kg8

68.Nf5 Kh7 69.Be3 Re1 70.Nxh6 Rxe3+

71.Kxe3 Kxh6 72.Kf4 1-0

The whole of the end game has been played by White with the greatest precision - Mackenzie.
