Jerome Gambit Secrets #4

One of my favorite Jerome Gambit "secrets" has actually been solved, but the story is always a good one to tell. And tell again.

Let's look at a line.

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



4...Kxf7 5.Nxe5+ Kf8

About 4 1/2 years ago I posted about this move
As early as his first article with analysis (Dubuque Chess Journal 4/1874), Alonzo Wheeler Jerome considered the possibility that Black might refuse to capture the second piece, and play for King safety instead with 5...Kf8 
This was, in fact, the defense that Jerome, himself, credited to G. J. Dougherty, ("a strong amateur, against whom I first played the opening") of Mineola, New York, in a yet unfound game; that O.A. Brownson, editor of the Dubuque Chess Journalplayed against Jerome in an 1875 game (Dubuque Chess Journal3/1875); that magazine editor William Hallock used against D.P. Norton in an 1876 correspondence game played “by special request” to test the gambit (American Chess Journal 2/1877); that William Carrington tried in his 1876 match vs Mexican Champion Andres Clemente Vazquez (Algunas Partidas de Ajedrez Jugadas en Mexico, 1879); and which Lt. Soren Anton Sorensen recommended as “more solid and easier to manage” in his seminal Jerome Gambit essay (Nordisk Skaktidende 5/1877). 
It is interesting that early in Jerome's Gambit's life, there were players willing to accept one "gift" but who were skeptical of accepting two "gifts".
6.Qh5

This move shows up in 38 games in The Database, with White scoring 49%.


As I noted

White also has the option of playing 6.Qh5, the Banks Variation, as in Banks - Rees, Halesowen, 2003, when Black can transpose with 6…Nxe5  as recommended by the American Chess Journal, (3/1877) - "The continuation adopted by Jerome, Qh5 looks promising." 
Pete Banks ("blackburne" online), a stalwart member of the Jerome GambitGemeinde (and still the strongest player I know who has played the Jerome regularly over-the-board in rated contests), brought international attention to Alonzo Wheeler Jerome's invention by writing to International Master Gary Lane, who commented at length on the opening, and on a couple of Banks' games, in his March ("The Good Old Days") and April ("Chess Made Easy") 2008 "Opening Lanes" columns at ChessCafe.com. IM Lane also mentioned one of Banks' games in his The Greatest Ever chess tricks and traps (2008), which reprised some of the earlier material. 
It is humorous to note that in his "Opening Lanes" column Lane wrote, after 5.Nxe5+, "I think anyone with good manners playing Black would now kindly ask their opponent if they wanted to take their move back" while in his book he changed this to "I think anyone with good manners playing Black would now go to another room to carry on laughing." 
Apropos the Banks Variation itself (i.e. playing 6.Qh5 in response to 5...Kf8), IM Lane noted in "The Good Old Days" that "6...Qe7 is a good alternative [to 6...Qf6 of Banks - Rees], because it stops the checkmate and protects the bishop on c5." 
A few months later, 6...Qe7 was tested successfully in a GameKnot.com game, splott - mika76, 20081.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Kf8 6.Qh5 Qe7 7.Ng6+ hxg6 8.Qxh8 Qxe4+ 9.Kf1 Qd4 10.Ke1 Qxf2+ 11.Kd1 d6 12.h3 Qxg2 13.Re1 Qf3+ 14.Re2 Bf2 15.d3 Nd4 16.Nc3 Qh1+ 17.Kd2 Nf3 checkmate. Clearly White, the very-slightly-higher rated player, was taken aback by the move. I asked mika76 if he had been influenced by IM Lane's recommendation, but he said he had come up with the move himself.

Jerome Gambit: A Mockery of Common Sense

Image result for free clip art crazy face

I really enjoyed the game in the previous post, so I looked in The Database for some more games by the Jerome Gambiteer obviously. The next game is even more wild, as White takes even greater risks - and wins.

obviously - grobnic
GameKnot.com, 2004

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



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 



This can lead to the infamous Blackburne Defense (7...d6), or the much-less-known but much-more-dangerous Whistler's Defense (7...Qe7).

7.Qxe5 Qe7 8.Qxh8

The Database is notoriously lean when it comes to either early Jerome Gambits, or over-the-board games. Coverage of Whistler's Defense is a good example.

There are 3 early correspondence games by Alonzo Wheeler Jerome (1876, 1879) where he scored 0-2-1.

Then, over 100 years later, there are then a handful of online games at FICS: 1 in 1999 (0-1); 1 in 2001 (1-0); 3 in 2003 (1-1-1); and then 10 in 2004 (4-5-1) - 7 of which involved obviously.

So, White's 8th move in the current game (capturing the Rook) probably deserves the same annotation it garnered in The American Chess Journal, June 15, 1876, when it showed up Jerome - Norton, correspondence, 1876 -
Played experimentally; and analysis will probably show the capture to be unsound. 
Analysis has since shown the capture of the Rook to be unsound - but, then again, analysis, even back in the 1870s, showed the Jerome Gambit itself to be unsound...

We must remember, however, that "all is new that has been forgotten", and that both players in the current game probably had little information on either the Whistler or the Jerome to guide them. That said, obviously obviously had some knowledge of the opening, as he scored 4-0-1 with the Black pieces, and 2-0 with the White pieces.

For that matter, The Database contains 59 games with the Whistler Defense, and White scores 57% - an indication that things are complicated enough that the first player will have his chances, at least in club play.

8...Qxe4+

This is the way to show that White's King is in more danger than Black's.

Bill Wall, who seems to be able to get away with just about anything in the Jerome Gambit, once experienced 8...Qf6 9.Qxh7+ Kf8 10.O-O Black resigned, Wall,B - Sepoli, Chess.com, 2010.

9.Kd1


This move is about as strong as 9.Kf1, e.g. 9...Nf6 10.d3 (10.Nc3 Qxc2 11.h4 b6 12.Qd8 Ba6+ White resigned, grobnic - obviously, GameKnot.com, 2004) 10...Qd4 (10...Qf5 11.f3 Bf8 12.Nc3 d5 13.h4 Qd7 14.h5 Bg7 15.hxg6+ Kxg6 16.Rh6+ Bxh6 17.Bxh6 b6 18.Ne2 Qf7 19.Qf8 Qxf8 20.Bxf8 drawn Jerome,A - Norton,D, correspondence, 1876) 11.Be3 Qxb2 12.Bxc5 Qxa1?! (12...d6 13.Ke2 Qxc2+ 14.Nd2 Bg4+ White resigned, flatchio - obviously, GameKnot.com, 2004) 13.Qf8+ Ke6 14.Qe7+ Kf5 15.Ke2 Qe5+ 16.Qxe5+ Kxe5 17.Re1 d6 18.Kf3+ Kf5 19.Bd4 Kg5 20.h4+ Kf5 21.Re7 Nd5 22.g4 checkmate, Wall,B - Neilson,C, Melbourne, FL 2017.

9...Qg4+

This move is good, but perhaps not quite as strong as 9...Qxg2, e.g. 10.Re1 (10.Qxh7+ Kf8 11.Re1 d5 12.d4 Bg4+ 13.Kd2 Qxf2+ 14.Re2 Qxe2+ 15.Kc3 Qc4+ 16.Kd2 Qxd4+ 17.Ke1 Qd1 checkmate, blackburne - perrypawnpusher, Jerome Gambit thematic, ChessWorld.net, 2008) 10...Qf3+ (going for a repetition in a winning position) 11.Re2 Qh1+ 12.Re1 Qf3+ 13.Re2 Qh1+ 14.Re1 Qf3+ drawn, Wall,B - Mathieubuntu, 40 0, FICS, 2011.

Black risked most of his advantage with the reasonable precaution 9...Nf6, although he was still able to outplay his opponent: 10.f3 Qh4 11.Nc3 b5 12.Qd8 Qg5 13.Ne4 Nxe4 14.Qxg5 Nxg5 15.d4 Be7 16.d5 h5 17.h4 Nh7 18.Bf4 d6 19.Ke2 Nf6 20.Rhd1 Bb7 21.Bg5 Nxd5 22.Bxe7 Nxe7 23.g4 hxg4 24.fxg4 Rh8 25.Rf1+ Ke8 26.h5 gxh5 27.g5 Rg8 28.Rg1 Bc8 29.Kd2 Bg4 30.Rg3 Rxg5 31.Re1 Kd7 32.Rh1 a5 33.Re1 h4 34.Rge3 Nd5 35.Re4 h3 36.R4e3 Nxe3 White resigned, vallabhan - obviously, GameKnot.com, 2004

10.Ke1

White improves on the historical 10.f3 Qxg2 11.Qxh7+ Kf8 12.Re1 d5 13.Qh4 Qxf3+ 14.Re2 Bg4 15.Nc3 Bf2 White resigned, Jerome,A - Whistler,G, correspondence, 1876.

10...Qxg2 11.Qxh7+ Kf8 12.Rf1 Qe4+


Again, good, but not best (12...d5). It is still hard to see how White will survive, but he does have a material advantage...

13.Kd1 d5

Chess can be incredibly cruel.

White's defense here has in good part consisted of shuttling his King back and forth. Black now plays the move recommended in the last note - and it turns over the advantage to his opponent.

It appears he needed to play 13...Qf3+ first. What difference does the check make? White shows with his next move.

14.f3 

In what appears to be a mockery of common sense, Stockfish 8 now claims that White has a clear advantage, giving 14...Qf4 15.Nc3 c6 16.Ne2 Qf6 17.d3 Bf5 18.Ng3 Re8 19.Nxf5 Qxf5 20.Bd2 Bd4 21.Kc1 Re7 22.Qh4 c5 23.a4 Re2 24.Kd1 Rg2 25.Qd8+ Kg7 26.Kc1 Bxb2+ 27.Kxb2 Rxd2 28.Qc7+ Kh8 29.Qxc5 Qxd3 30.Rf2.

14...Bg4 

It is difficult to explain this move. It is tempting to suggest a mouse slip, but the time control for this game was 5 days per move.

15.fxg4+ Nf6 Black resigned


After 16.Rxf6+ Ke8 17.Nc3!? White's pieces will be able to protect his King from too many Queen checks, while Black's King will be open to great dangers.

Jerome Gambit: A Casual Stroll

Bill Wall recently sent me a few more of his Jerome Gambits. As he said, some are good, some are bad. None are quite as outrageous as the following.

Wall, Bill - Neilson, Criag
Florida, USA, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



This appears to be an over-the-board game, which already makes it very interesting.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ 



Interesting. Bill moves away from his favorite 6.d4.

6...g6 7.Qxe5 Qe7 8.Qxh8 



Wow! Into the mouth of the beast!

One of the many reasons the Jerome Gambit is considered "unplayable" is Whistler's Defense (7...Qe7!). The Rook is supposed to be untouchable.

Not for Bill Wall. "Danger" is his midde name. He considers things like the Pamplona bull run to be a casual stroll down some interesting avenues.

8...Qxe4+ 

After 8...Qf6 the game did not last long: 9.Qxh7+ Kf8 10.O-O Black resigned, Wall,B - Sepoli, Chess.com, 2010

9.Kf1 

The alternative, 9.Kd1, was seen in Jerome,A-Whistler,G, correspondence, 1876 (0-1, 15) - but also in Wall,B - Mathieubuntu, FICS, 2011 (1/2-1/2, 14).

9...Nf6 10.d3 Qd4

This looks like an improvement over 10...Qf5 in Jerome,A - Norton,D, correspondence, 1876 (1/2-1/2, 20). 

11.Be3 Qxb2 12.Bxc5 Qxa1 



It looks like things will come down to which King is the most vulnerable.

13.Qf8+ Ke6 14.Qe7+ Kf5 15.Ke2 Qe5+ 16.Qxe5+ Kxe5


Very interesting. Is Black for choice because his King is better developed? Or will the blocked-in-light-squared-Bishop-blocking-the-Rook theme give White an edge?

17.Re1 d6 18.Kf3+ Kf5 19.Bd4 Kg5



A dangerous slip.

20.h4+ Kf5 21.Re7 Nd5 

Overlooking...

22.g4 checkmate

Jerome Gambit: A Norton Link

I recently heard from 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 (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+).

While I pursue the possibility of further historical discoveries, I thought I would point out earlier coverage of the Nortons on this blog:

"A sparkling variation to the tiresome Piano game"

"Jerome Gambit Tournament: Chapter II"

"Jerome Gambit Tournament: Chapter III"

"Critical Line: 5...Kf8 (1)"

"The Life of Alonzo Wheeler Jerome"

"The Jerome - Norton Games (Parts 1, 2, 3 & 4)"

"The Norton - Hallock Game (Parts 1, 2, 3 & 4)"

Jerome Gambit Positional Play

The first thing that comes to mind at the mention of the Jerome Gambit is not "positional play". Yet, in the following game Bill Wall works to delay the development of Black's light-squared Bishop (a state of affairs that is often deadly for the second player) even at the cost of trading Queens. 

Wall, Bill- NN
lichess.org, 2016

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



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4
Qf6 

With both defense and a trap in mind.

8.Qc5 Qd6 9.Qxd6 

Black's Bishop will not be travelling on the c8-h3 diagonal.

For 9.Qc3 see Wall, B - Guest3967134, PlayChess.com, 2015Also 8.Qe3 as in Wall,B - Tsyalex, PlayChess.com, 2015 (1-0, 20); and 8.Qd1 as seen in an unfinished correspondence game Jerome,A - Norton, D.P., 1876, and the later Jerome,A - Jaeger,D, correspondence, 1879, (1-0, 35).

Don't overlook "Why Did He Play That Move?"


9...cxd6 10.Bf4

The alternative, 10.O-O, was seen in Wall,B - berserkergang, FICS, 2011(1-0, 21).

10...Nf6 11.Nc3 b6 12.O-O-O Ke6 13.Nb5 



13...Nxe4

Black protects the pawn at d6, but not the space at c7. Perhaps he has his eyes on his own fork at f2.

14.Nc7+ Ke7 15.Nxa8 Nxf2 16.Bg5+ Kf7



Not as good is 16...Ke6, i.e. 17.Rhf1 Ned3+ (not 17...Nxd1 18.Nc7#) 18.cxd3 Nxd1 19.Nc7+ Ke5 20.Kxd1 Bb7. Black's Bishop is finally developed, but he is worse.

Black continues, but his oversight on move 21 seals the game.

17.Rhf1 Kg6 18.Rxf2 Kxg5 19.Nc7 Bb7 20.Nb5 a6 21.Nxd6
Be4 22.Nxe4+ Black resigned

Don't Worry, I've Got This


There are so many ways to defeat the Jerome Gambit, it's not surprising to see Black, in the following game, attempt several of them. I suppose that any one of them could work - on a different day, in a different game, against a different player...

Wall, Bill - Guest3967134
PlayChess.com, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 Qf6

Black has given back one of the sacrificed pieces, and then developed his Queen to where it protects his King, controls the center and threatens an exchange. Surely, this is enough?

8.Qc5

A couple of notable alternatives:

8.Qe3 as in Wall,B - Tsyalex, PlayChess.com, 2015 (1-0, 20); and 
8.Qd1 as seen in an unfinished correspondence game Jerome,A - Norton, D.P., 1876, and the later Jerome,A - Jaeger,D, correspondence, 1879, (1-0, 35).

Don't overlook "Why Did He Play That Move?"

8...Qd6 9.Qc3

The positional 9.Qxd6!? was seen in Wall,B - berserkergang, FICS, 2011: 9...cxd6 10. O-O Nf6 11. Nc3 a6 12. Rd1 Ke7 13. b3 b5 14. Ba3 Nf7 15. e5 Ne8 16. exd6+ Nexd6 17. Ne4 Bb7 18. Nxd6 Nxd6 19. Rxd6 Kd8 20. Rad1 Bc6 21.Rxc6 Black resigned

9...Nf6 10.Bf4 Nxe4

Giving back the other sacrificed piece. Surely, this at least draws? 

11.Qxe5 Qxe5 12.Bxe5 d6 



13.f3 Re8 14.fxe4 Rxe5 15.Nc3 c6



Black has play against White's isolated e-pawn - plus a Bishop for a Knight. Winning in the endgame is no shame.

16.Rf1+ Kg8 17.O-O-O d5 18.exd5 Bd7 19.dxc6 Bxc6



Black has sacrificed a pawn for dynamic piece play. Look at that Bishop!

20.g3 Rae8 21.Rd4 h6 22.Kd2 a6 23.a3 Bb5 24.Nxb5 axb5 25.Rf2 b6

Okay, maybe things are going a bit awry for Black...

26.Rd6 Kh7 27.Rxb6 Rd5+ 28.Kc3 Re3+ 29.Kb4 Re4+ 30.Kb3 Re3+ 31.c3 Rde5 32.Rb7 Re7 33.Rxb5 Re2 34.Rxe2 Rxe2 35.a4



 35...Rxh2 36.a5 Rg2 37.a6 Rxg3 38.a7 Black resigned

Cuts Like A Knife

Sharp variations can work in favor of the gambiteer, or cut against him. It is important to be as up-to-date as possible on the tricky variations.

I recently downloaded some more games from the Free Internet Chess Server (FICS), and, as well as checking out some "old" Jerome Gambiteers (e.g. drumme, HauntedKnight, Petasluk), looked at the efforts of a relatively new member of the Gemeinde, ZahariSokolov.

In the following game he faces a rare, but old and dangerous defense, and, under pressure, chooses the wrong line (although, in another game in the notes, this also leads to victory), and suffers defeat.

I have added some game references for Readers to have a better idea of how to deal with this kind of play.   

ZahariSokolov - Quarte
standard, FICS, 2015

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



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Nf3+ 



This surprising move, attributed to Norton - who defeated Alonzo Wheeler Jerome with it in a correspondence game in the early years of the gambit - rips open White's Kingside and makes him vulnerable to attack.

9.gxf3

Probably the only move, although I have gotten away with 9.Kf1 a couple of times in perrypawnpusher - igormsp, blitz, FICS, 2011 (1-0, 13), and perrypawnpusher - rheapennata, blitz, FICS, 2012 (1-0,12); while Jerome, as mentioned, did not - Jerome,A - Norton,D, Correspondence, 1876 (0-1, 42).

ZahariSokolov, himself, a few days earlier, had gotten away with 
9.Kd1: 9...Nd4 (9...Ne7!) 10.Qd5+ Ke7 11.Qxc5+ d6 12.Qxd4 Bg4+ 13.Ke1 c5 14.Qxg7+ Ke8 15.Qxg4 Nf6 16.Qe6+ Qe7 17.Qxe7+ Kxe7 18.d3 h6 19.Nc3 a6 20.Be3 b5 21.Ke2 Rhg8 22.g3 b4 23.Nd5+ Nxd5 24.exd5 Kf6 25.Rae1 Kf5 26.Kd2 h5 27.Bf2 Rae8 28.Rxe8 Rxe8 29.Re1 Rxe1 30.Bxe1 Kg4 31.Ke3 Kh3 32.f5 Black resigned, ZahariSokolov - LAVAL, standard, FICS, 2015


9...Qh4+ 10.Ke2

The "only" move, this time, is 10.Kd1: CFBBlind - Quandary, FICS, 2001 (1-0, 18); perrypawnpusher - Sir Osis of the Liver, JG3 thematic, ChessWorld.net, 2008 (1-0, 19);  perrypawnpusher - sjeijk, blitz, FICS, 2011 (1-0, 19);  ZahariSokolov - GhengusFungus, FICS, 2014 (1-0, 11).

10...Qf2+ 11.Kd3 Qxf3+ 12.Kc4 b5+ 13.Kxb5 Qe2+


A testimony to White's ability to struggle and survive: 13...a6+ 14.Kc4 Nf6? 15.Qxc5+ Ke6 16.Re1 Qxf4 17.d3 Qd6 18.Qxd6+ Kxd6 19.e5+ Kc6 20.exf6 gxf6 21.b3 d5+ 22.Kc3 Bg4 23.Bf4 h5 24.h4 f5 25.d4 Rhe8 26.Rxe8 Rxe8 27.Be5 Rf8 28.Nd2 f4 29.Rf1 f3 30.Rf2 Kb6 31.Kd3 c5 32.c4 dxc4+ 33.bxc4 cxd4 34.Bxd4+ Kc6 35.Ke4 Re8+ 36.Kf4 Rf8+ 37.Kg3 Rd8 38.Bf6 Rd3 39.Nxf3 Bxf3 40.Rxf3 Rxf3+ 41.Kxf3 Kc5 42.a3 Kxc4 43.Kf4 Kd5 44.Kg5 Ke6 45.Bc3 Kf7 46.Kxh5 Kg8 47.Kg6 Kf8 48.h5 Black resigned, gibonacci - jschulte, GameKnot.com, 2007.

A testimony to an early chess computer's terrible addiction to grabbing material: 13...Rb8+ 14.Ka5 Bb4+ 15.Ka4 Qxh1 16.Qe5+ Kc6 17.Qd5+ Kb6 18.Qb5 checkmate,  Young,J - Chess, Computer game, 1979.

There Are Some Risks We Should Not Take.


Let's face it, some players succeed with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) - even the more difficult lines - because they are strong, and they would succeed against their opponents whatever opening they used.

Then, there is the rest of us. Staying away from really bad lines (relatively speaking: remember, we are talking about the Jerome Gambit here) is essential. Never mind that our heroes have played them and escaped to triumph. There are some risks we should not take.


Galamon - GimpBishop

blitz, FICS, 2015

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




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Qe7 




Whistler's Defense. Stronger, much less known, and more dangerous for White than Blackburne's Defense (7...d6).

Do yourself a favor as a Jerome Gambiteer: don't take the Rook.


8.Qxh8 Qxe4+ 9.Kf1


Yes, I know that Bill Wall once played the equally painful 9.Kd1 and managed a draw in Wall,B - Mathieubuntu, blitz 10 0, FICS, 2011 (1/2-1/2, 14). Better to remember the lessons of Jerome,A - Whistler,G, correspondence, 1876 (0-1, 15)


9...Qxc2


Yes, I know that against 9...Nf6 ZahariSokolov at FICS won his game last year (ZahariSokolov - Dragonianlee, FICS, 2014 [1-0, 20]) and Alonzo Wheeler Jerome achieved a draw, a long time ago, in a correspondence game (Jerome,A - Norton,D, correspondence, 1876 [½-½, 20]) but both were fortunate; and while the text is okay, 9...Qh4!? is stronger than either it or 9...Nf6.


10.Qxh7+ Kf8


If you have access to The Database you might want to point out to me that after 10...Kf6 White won in markinchrist - Gurucool, blitz, FICS, 2013 (1-0, 20) - but that was only because Black forfeited by disconnection when he had a forced checkmate in 9 moves.


11.Qxg6


A blunder.


Yes, chessmanjeff of FICS both won and lost games with 11.Nc3 (chessmanjeff - CHESSWILL, blitz, FICS, 2013 [1-0, 38]  and chessmanjeff - throwback, blitz, FICS, 2014 [0-1, 16]) - that's scoring 50%, right? - but "objectively" Black's game was still better.


11...Qd1 checkmate
