Jerome Gambit: Return to the Literary Digest

In mid-1900, Alonzo Wheeler Jerome convinced the chess columnist for the Literary Digest to start a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) consultation game involving the magazine's readers. The tale of this match was told on this blog in "A Jerome Discovery (Parts 1234, and 5)".


I found myself returning to the last of Jerome's suggestions, which I had reported without comment.

The game had proceeded this far -

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5 Nxe5 6.d4 Qh4 7.0-0 Ng4 8.h3 Bd6 



This position was seen as far back as Sorensen - NN, Denmark, 1888 (1-0, 27).

9.f4 h5

At this point, the Literary Digest continued (descriptive notation changed to algebraic)
Mr. Jerome suggests White's 9th move instead of e5, and writes: "This looks like a sure move for White." Black has, in reply, two moves: ...Nh6, saving the piece, or ...h5. We prefer the latter, as it is evident that Black [sic: it should read White] can not play hxg4.
I have to admit that Jerome was not at his sharpest in "improving" upon Sorensen's play. (According to The Database, 9.f4 is a novelty.)

For starters, the chess columnist at the Literary Digest was correct, that 10.hxg4 was unplayable, as, after 10...hxg4, Black would be threatening 11...g3 with checkmating threats that would cost White his Queen, unless he played the best (but still inadequate) 11.Re1 - the immediate 11...g3 would be strong, while developing moves such as 11...Nf6 or 11...b6 (preparing ...Ba6, covering the escape square f1) would be even stronger.

White would have to answer 9...h5 with 10.Qd3 (keeping the enemy Queen out of g3) when some caution by Black, such as 10...Bf8 or 10...N4h6 should allow him to eventually take advantage of his two-pieces-for-two-pawns material imbalance.

Of course, Black's alternative line of play, 9...N4h6, also allows him to hang onto material, and as long as he avoids opening lines for White's Rook, his advantage should tell.

Kicking the enemy Bishop with 9.e5, as in the Sorensen game, seems best for White, although Black should retreat his Bishop with 9...Be7 (a novelty, according to The Database) - not return it for pawns, as Sorensen's opponent did, with 9...Bxe5. White can then grab the Knight with 10.hxg4, and side-step the thematic 10...h5 with 11.g5, but his game will still be worse after 11...Qg4 (not 11...Bxg5, because of 12.g3!?, which will cost Black the Bishop.

Jerome Gambit: Complications Favor the Strong

The story of the following game is straight-forward: after a few chuckles in the opening, complications ensue. In complicated positions, stronger players are more likely to find their way, while more average players are more likely to get lost. And so it goes...

Wall, Bill - Guest2910393
PlayChess.com, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




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



I always get a chuckle out of this move. Black simply threatens to play ...Nf3+, winning the - currently - unprotected White Queen. Maybe. The move is as old as Jerome - Norton, correspondence, 1876 (unfinished).

7...Qf6 is a good move, Stockfish 10's second choice, behind 7...d6

Furthermore, The Database - a reasonably representative sample of online club chess play - has 180 games with 7...Qf6, with White scoring only 40%.

Interestingly enough, The Datbase has 21 games where White does not move or protect his Queen, and Black executes the King-and-Queen-fork. However, there are 40 games where White does not move or protect his Queen, and Black overlooks the King-and-Queen-fork. Ooooops.

This split is illustrated in the experience of a long-time Jerome Gambit player who has 187 games in The Database, and who has been forked 3 times from this position. However, 8 other times his opponent was presented with the opportunity, but missed the Knight check.

Chaos runs deep in the Jerome Gambit. Club play is not a simple thing.

8.Qc5 

This move is Bill's favorite, although he has also tried 8.Nd28.Be38.Qc3, 8.Qd2 and 8.Qe3.

8...Ne7 9.Nc3 

In an earlier game Bill grabbed a pawn, and then slowly ground down his opponent: 9.Qxc7 b6 10.Qc3 Ba6 11.Qa3 Qg6 12.Qxa6 Qxe4+ 13.Kf1 Qxc2 14.Nc3 Nd3 15.Be3 Rac8 16.Qa3 Qxb2 17.Qxb2 Nxb2 18.Bd2 Nf5 19.Re1 Nd6 20.Re2 Ndc4 21.Be1 Rce8 22.Nb5 Nd3 23.Bc3 a6 24.Nc7 Rc8 25.Nxa6 Nce5 26.Bd2 Rc4 27.g3 Ra8 28.Nb4 d6 29.Nxd3 Nxd3 30.Re3 Ne5 31.a3 Rd4 32.Bb4 Nc6 33.Kg2 Ra6 34.Rf3+ Ke6 35.Re1+ Kd5 36.Rf5+ Ne5 37.Bxd6 Kxd6 38.Rfxe5 Rxa3 39.Re6+ Kd7 40.Rxb6 Ra7 41.Rbe6 Rda4 42.h4 R4a5 43.f4 Ra1 44.Rxa1 Rxa1 45.Re5 Ra7 46.Kf3 Kd6 47.Kg4 Ra3 48.h5 Ra1 49.Re8 Rb1 50.f5 Rb7 51.Kg5 Rb4 52.Rg8 Rb7 53.g4 Rc7 54.Rh8 h6+ 55.Kg6 Ra7 56.Rg8 Ra4 57.Kh7 Ke5 58.Rxg7 Kf4 59.Kxh6 Black resigned, Wall,B - Computer-13, Chess.com, 2017.

9...Ng4 

10.f3 Ne5 11.Qxc7 

Grabbing the pawn, after all.

11...N7c6 12.O-O 

A complicated position. Black has an extra piece for two pawns, and is slightly better developed, although he has the standard problem often facing those who defend against Jerome Gambit: his pawn blocks his Bishop which blocks his Rook... A significant factor is that White's Queen is a bit trapped in the enemy position, and Stockfish 10 suggests White work towards b2-b3, Ba3, and then Qd6, exchanging the Queen. If Black could then focus on untangling his pieces, he would maintain an edge. 

12...Kg6

The first of two puzzling moves that end the game.

My guess is that Black was unpinning his d-pawn so that it could advance, but the King move is too risky.

13.Nd5

White now has the advantage in a tricky position, but Black is not finished with his surprises.

13...Qe6 14.Nf4+ 

Black resigned

Jerome Gambit: Lost In The Weeds


Image result for free clip art lost in the weeds



The following Jerome Gambit game is another example of a defender doing well, objectively, until he gets lost in the weeds, off the beaten path...

Wall, Bill - Guest4241
ChessTempo, 2019

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




4...Kxf7 5. Nxe5+ Nxe5 6. d4 Bxd4 



Simple and straight forward.

7.Qxd4 Qf6 


Funny: the threat is 8...Nf3+, winning White's Queen. It is as old as Jerome - Norton, correspondence, 1876 (unfinished). The move is no surprise, though, to Bill: he has faced it 20 times.

8.Nd2 d6 9.O-O Ne7 10.f4 N5c6 



Black is doing well. He needs a plan. The plan should be based on the needs of the position. White should mess with all that assessment and calculation.

11.Qc4+ 

This is something new, according to The Database. Sometimes, Bill likes to take the game even further off the beaten path.

11...Be6 12.Qb5 Qd4+ 13.Rf2 b6 



Just the kind of thing that White has been looking for.

Of course, Black could have played 13...Qb6, protecting his b-pawn and offering to exchange Queens, but he probably skipped that line because he saw himself as being on the attack, so having his Queen would be valuable. (Besides, White would have responded with 14.Qe2.)

The thing is, Black's b-pawn is not really in danger, as 13...a6 14.Qxb7? Ra7 would show. A more measured response by White would still show that Black is better: 14.Qe2 Kg8 15.Nf3 Qf6.

14.Nf3 Qxe4 

Throwing the game away. It is humorous to see that Stockfish 10 recommends as best, instead, the Queen swap 14...Qc4 15.Qxc4 Bxc4 - something Black has been avoiding.

15.Ng5+ Kg6 16.Nxe4 Black resigned

Jerome Gambit: Odd Turns (Part 1)







I just finished a Jerome Gambit game in an Italian Game tournament at Chess.com. It took a couple of odd turns - played as well as unplayed.

Then, again, that's the Jerome Gambit for you.

perrypawnpusher - Sarantes
"Let's Play The Italian Game" tournament
Chess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 

Jerome's Defense, appearing in his analysis of "Jerome's Double Opening" in the July 1874 issue of the Dubuque Chess Journal, and seen, initially, in Jaeger - Jerome, correspondence, 1880 (1-0, 40).


7.Qxe5 d6 8.Qg3 Nf6 9.d3 Be6 10.O-O Nh5 



Black has a number of choices, as can be seen from some earlier games:

10...Qd7 11.Be3 Bb6 12.Nd2 Ng4 13.Bxb6 axb6 14.h3 Nf6 15.a3 h6 16.f4 Rg8 17.f5 Bf7 18.Qe3 Re8 19.g4 Nd5 20.Qd4 c5 21.Qf2 Nf6 22.b3 b5 23.Qf4 Qc7 24.a4 bxa4 25.Rxa4 b5 26.Ra6 Rd8 27.Rfa1 Ke7 28.Ra7 Black resigned, mrjoker - PhlebasP, Internet Chess Club, 2009;

10...Kf7 11.Be3 Bb6 12.Nc3 Rf8 13.f4 Kg8 14.f5 Bxe3+ 15.Qxe3 Bd7 16.h3 a6 17.g4 c6 18.Rae1 b5 19.Kg2 b4 20.Ne2 a5 21.Qf4 Bc8 22.Ng3 Bb7 23.g5 Ne8 24.d4 c5 25.d5 Nc7 26.h4 Ba6 27.Rf2 Nb5 28.Ne2 a4 29.c4 bxc3 30.bxc3 Na3 31.Qc1 Bxe2 32.Rfxe2 Nc4 33.Qf4 Ne5 34.Rb1 Rb8 35.Reb2 Rxb2+ 36.Rxb2 White resigned, MrJoker - rgiblon, Internet Chess Club 2012; 

11.Qf3+ Nf6 

The placement of White's Queen is problematic. On g3 it is vulnerable to attention by Black's Knight. On f3 it can be harassed by Black's Bishop. It tends to keep Black's King on f8, but that is not, necessarily, a bad thing.

12.Be3 Bb6

Another issue in this kind of position: to exchange Bishops or not. It's probably safe to comment on any exchange with "shouldn't have" and on any non-exchange with "should have exchanged".

13.Nc3 

The Knight has a good "present" here, but I wonder if it would have a better "future" at d2.

13...Kg8 14.Qe2 Qd7 15.f4 Bf7 16.Rae1 Re8 


Black has the extra piece (vs 2 pawns) and the two Bishops. He is not even worried about his Rook at h8. 

White has developed his pieces, and has to find a way to use his "Jerome pawns".

17.Qf3 

I have played over many Jerome Gambits by those much stronger than myself. Sometimes patience is the key. 

17...Qg4 18.Qf2 h5 19.Bxb6 axb6 20.b3 


I admit that this is an odd-looking move. I wanted to be able to play d4 without being bothered by ...Bc4. It just didn't seem to be the time for 21.e5 yet.

20...h4 21.Qf3

I did not like Black's developing action along the h-file, and reluctantly agreed that it was time to swap the Queens.

21...Qxf3 22.Rxf3 Nd5 23.Nxd5 Bxd5 24.Rfe3 Bc6 



Looking at the position, it is clear that White will play d4, and maybe even c4 and g4. He is going to need some help, however.

Black has a solid, attacking Bishop on c6, and both Rooks are in good position. Clearly, he is better.

Jerome Gambit: Speeding It Up Again

Image result for free clip art fast superhero
After a close look at a couple of "slow" over-the-board tournament games - where there is time for assessment and planning - it is time to switch to checking out another lightning game, where confidence, intuition and blink-fast decision-making are key.

Welcome back, Cliff Hardy.

Notes are primarily by Hardy [I have added a few comments in blue - Rick


Cliff Hardy (2176) - NN (1842), 
1 0, Lichess, 2018

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


4...Kxf7 5. Nxe5+ Nxe5 6. Qh5+ Kf8 


[The Jerome Variation of the Jerome Gambit, played by Alonzo Wheeler Jerome against David Jaeger in correspondence, 1880. - Rick]

7.Qxe5 d6 8.Qg3 Nf6 9.Nc3 Be6 10.0-0 Ke7?


[The King does not belong on the e-file, and White needs to find a way to demonstrate this. In a slow game, that would be not much of a challenge. When you have 1 or 2 seconds per move - now that's a challenge - Rick]

Stockfish found that White could take the g-pawn here with the very strong 11.d4!! Bxd4 12.Qxg7+ Bf7 13.Bg5 c6 (or 13...Rg8 14.Bxf6+ Bxf6 15.Nd5+! Ke6 16.Qxh7 ++-, when Black's king would be perilously placed on e6) 14.e5!! Bxe5 15.Rae1 ++-, when White would be threatening to take the knight for free on f6 or to attack the pinned bishop with 16.f4, but I would never have been able to find this line in 1 0 chess (nor in a full-length game ðŸ˜‰).

11.d3? Rf8?! 12.Be3?

Rather than go for Morin's c3, d4 approach [see Morin - Guipi Bopala, Quebec Open, 2018 - Rick] to blunting Black's dark-squared bishop, I chose to blunt it with my own bishop, in an attempt to advance my pinned f-pawn. But since Black has still left his g-pawn vulnerable, Stockfish prefers 12.Na4 Bb6 13.Nxb6 axb6 14.Qxg7+, though Black would then have had a slight advantage after 14...Rf7.

12...Bb6?

12...Bxe3 would not have lost time in retreating and would have yielded Black a winning advantage here.

13.d4 

By now the time for White to capture the g-pawn had well and truly past, since from here on it would just lose time with the queen for White and open the g-file for Black to use in attacking the white king.

13...Qe8 14.f4 Qh5 15.f5 Bc4 16.Rf4 Rae8 17.b3 Ba6 



18.Re1? 

Getting the Jerome pawns mobilised immediately with 18.Rh4 Qf7 19.e5 ++-, while Black's king is still sitting on e7, would have been much better.

18...Kd7 19.Bf2 Qf7 20.e5 dxe5 21.dxe5 Nd5?? 


The final losing move. 21...Nh5 would actually have been winning for Black, since then 22. e6+ Kc8 23. exf7?? would have been met with 23...Rxe1 mate!

22.e6+ Rxe6 23.fxe6+ and white won on time, though Black is lost in any case.

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.
