Ooops...

Image result for clipart embarrassed face
I have given periodic updates on the Giuoco Piano thematic tournament at Chess.com that I am playing in, under the belief that I - surprisingly - was going to finish at the top of the field, thanks to a lot of teriffic battling amongst players, and to the Jerome Gambit.

Much to my surprise, and some embarassment, I have learned that there is one more round to play!

So, I will have black and white against IlToscano and AWARDCHESS, who finished the previous round ranked #2 and #3 respectively. (The latter moved ahead of Altotemmi on tie breaks, 93.75 to 93.5!)

Apologies for prematurely claiming victory in the tournament.

My successes with the Jerome Gambit in the earlier round against my current opponents came mostly due to the element of surprise. I expect to have even harder fights this time around.

Blackburne Shilling Jerome Gambit: This Is Why We Play It

White has several very reasonable responses to Black's third move, only one of which - 4.Bxf7+ - calls to mind the Jerome Gambit. Still, playing that last one often means a short end to hostilities. Bill Wall demonstrates in the game below.

4...Kxf7 5.Nxe5+ Ke6 6.c3 Kxe5 7.cxd4+Kxd4


A risky meal.

8.d3 b6 



And just like that, it's Game Over. Black does not have time for this development; checkmate follows.

Jerome Gambit: Worth A Scold?

When Bill Wall sent me his latest batch of Jerome Gambit games he mentioned in passing that one opponent had been irate at having to face such a horrible opening, and pointed it out in a message afterwards - clearly it was something Bill should never play, that Bill would lose with should he play it against World Champion Magnus Carlsen, etc. Bill never identified the opponent or the game to me, but if I were to guess, I would choose the following contest. Black starts off using the advantage that the defender always has against the Jerome Gambit, and develops a decent attack - until one suspicious move (which doesn't look that bad) suddenly reverses the game; and even when Black resigns, it takes some work to understand why.   

Wall, Bill - Youi
lichess.org, 2017

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



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qe7



A perfectly reasonable defense. Black is going to lose a piece any way, so he focuses on development, not un-development.

7.dxc5 Qxc5 8.O-O Nf6 9.Be3 Qd6



Excellent psychology. Black offers to exchange Queens to reduce chances of attack by White. He even tosses in the attraction of giving Black doubled d-pawns, limiting the development of his light-squared Bishop.

Bill has seen altarnatives:

9...Qc6 10.Nc3 d6 11.Bd4 Re8 12.f4 Ned7 13.Re1 b5 14.a4 bxa4 15.b4 a6 16.Rxa4 Bb7 17.Ra5 Nxe4 18.Qh5+ Kg8 19.b5 Qc4 20.Ra4 Qf7 21.Qxf7+ Kxf7 22.Nxe4 Rxe4 23.Rxe4 Bxe4 24.Rxa6 Kg6 25.c3 Bb7 26.Rxa8 Bxa8 27.h4 Bd5 28.g4 Bc4 29.f5+ Kf7 30.Kf2 Bxb5 White resigned, Wall,B - NN, lichess.org, 2016; and

9...Qb5 10.Nc3 Qxb2 11.Bd4 d6 12.Nd5 Qa3 13.Nxc7 Rb8 14.Nb5 Qa6 15.Bxa7 Bd7 16.Nxd6+ Ke6 17.Bxb8 Rxb8 18.Nf5 g6 19.Ne3 Bc6 20.Qd4 Bxe4 21.f3 Bc6 22.Rae1 Qa3 23.Nc4 Black resigned, Wall,B - Guest3992982, PlayChess.com, 2015.

10.Bd4

No, thank you.

10...Re8 11.Nc3 c5 12.Nb5

Looking to cause mischief on the d6 square.

12...Qc6 13.Bxe5 Rxe5 14.Nd6+ Kg8 




15.f4 Re6 16.e5 Ne8 17.Nc4 b5 18.f5 Bb7 19.Rf2 Rh6



Black persists in his attack. What can White do?

20.Na5 Qd5 21.Qe2 Nc7




He can continue to present Black with threats and complications until Black slips. Like here. Bill uses his x-ray vision and comes up with a solution.

22.Rd1 Qxa2

The strongest defense was 22...Qe4, but after 23.Rxd7 Qxe2 24.Rxe2 Bc8 25.Rxc7 Bxf5 White would be better.

23.Nxb7 Qxb2 24.Nxc5 Black resigned



Wow.

A quick look shows that White will win the pawn at d7, but is that enough to cause resignation?

A longer look will show that f5-f6 is a strong attacking threat, and that White's "Jerome pawns" are much more of a threat than Black's Queenside pawns.

BSJG: Reference


Image result for clip art email

I received a short email from chessfriend Yury Bukayev, regarding yesterday's blog post. I have added the relevant link:


Your latest post http://jeromegambit.blogspot.ru/2017/03/blackburne-shilling-jerome-gambit-be.html contains the final attack, that is relative to winning attacks in Evans-Bukayev gambits (for example, III.B2 of my Paragraph 2). It is pleasant to see! 
Best wishes!
Yury

Blackburne Shilling Jerome Gambit: Be Ready to End Quickly

In the Blackburne Shilling Gambit Black offers material and hopes for a tricky attack.

In the Blackburne Shilling Jerome Gambit White offers more material and hopes for a trickier attack.

Playing over the following game, do not blink: both players are hoping for a quick ending, and they both receive their wish.

4...Kxf7 5.Nxe5+ Ke6 6.c3 Nb5 


An interesting, if flawed retreat. It doesn't look that bad.

There are 12 games in The Database with this move. White scores 75%. Compare this with the 56% overall that White scores against the BSJG (out of 5,307 games in The Database). 

7.d4 Bd6 

Looks tough, but looks can be deceiving.

Jerome Gambit: I Forget How Complicated

Vlasta Fejfar shares his latest Jerome Gambit. I forget how complicated the game can get.

Vlastous - Kombe
internet, 2017

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




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Qf6




I am pretty sure that Vlasta was happy to get a break from the "annoying defense" 7...d6.

8.Rf1 Nd3+ 


Creatively returning a piece. (It is not the strongest response, however.)


9.cxd3 Bd4


Plotting or planning something, but I am not sure what... Probably the simple 9...d6 was better.

10.Nc3

This is a small improvement over 10.Qd5+, which appeared in an earlier game, the only other one in The Database to feature 8...Nd3+10...Ke7 11.e5 Qh4+ 12. g3 Qxh2 13. Qxd4 Qxg3+ 14. Qf2 Qxf2+ 15. Rxf2 b6 16. d4 Nh6 17. Nc3 c6 18. f5 Bb7 19. d3 Raf8 20. Bxh6 gxh6 21. O-O-O Rf7 22. Ne4 Ba6 23. Nd6 Rff8 24. Kd2 Rhg8 25. f6+ Ke6 26. f7 Rg3 27. Rf6+ Ke7 28. Nf5+ Kd8 29. Nxg3 Black disconnected and forfeited, MrJoker - Melbourne, Internet Chess Club, 2011.

10...g6

Kicking the Queen makes a lot of sense - sometimes; but not right now. A typical Jerome Gambit problem for Black: what is good, and what is not?

11.f5+ gxf5

A measure of how complicated the game has become is shown in Stockfish 8's recommendation: 11...Ke7 12.fxg6 Qxg6 13.Qh4+ Ke8 14.Nd5 Be5 15.b4 d6 16.Rb1 Be6 17.Nxc7+ Kd7 18.Nxa8 Qxg2 19.Bb2 Bxb2 20.Rxb2 Ne7 21.Qf2 Qxf2+ 22.Kxf2 Rf8+ 23.Ke2 Rxa8 24.Ke3 d5 25.b5 Kd6 26.Rb4 Ng6 27.Ra4 leading to an even game.

The text turns the advantage over to White.

12.exf5+ Ke7 13.Nd5+ Kd6 14.Nxf6 Nxf6 15.Qh4 Re8+ 16.Kd1 b6

Assuming that a Queen is worth three pieces, for a moment it looks as if it is Black who has sacrifice a piece to attack White's uncastled King. Alas, the second player's game has come undone.

17.Qxd4+ Ke7 18.Re1+ Kf7 19.Rxe8 Nxe8 20.Qd5+ Ke7 21.Qe4+ Kd8 22.Qh4+ Black resigned

Jerome Gambit: Other Links?

The previous post mentioned that I had recently been contacted by
the great, great, great, great grandson of Dennis Platt Norton, a chess player who, along with his son, Frank C. Norton, played an early part in the development of the Jerome Gambit
There are other historical figures who would shed more light on Alonzo Wheeler Jerome's opening, if only we knew more about them.

For example, the “Our Portfolio” section of the Dubuque Chess Journal for May 1874, contained a “Chess Challenge” which looked a lot like a chess duel

George J. Dougherty, of Mineola, Queen’s County, New Yorkhereby respectfully invites John G. Belden, Esq., of Hartford, Conn.to play him two games of chess by Postal Card, at his convenienceMr. Belden taking the attack in one game and Mr. Dougherty in the other; the object being to test the soundness of JEROME’S DOUBLE OPENINGpublished in the April No. (50) of this CHESS JOURNAL.
  
We know that, according to Jerome, Dougherty was the first opponent to face the Jerome Gambit; but, beyond that, very little. Of Belden - or even if the challenge was ever taken up - nothing further is known.

There is also Lt. G. N. Whistler, secretary of the Lexington, Kentucky Chess Club, with whom Jerome played a correspondence match in 1876, where "Whistler's Defense" (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Qe7!?) made an early appearance. There is only one game from that match in The Database.

Jerome tosses off a few names in relation to his games, including B.K. Neufville, all who remain relatively mysterious.

There is so much more history to uncover!
