Jerome Gambit: Another Day In The Life Of

Image result for free clip art chaos


Here is another (see "Jerome Gambit: Full-Bodied Defense") Jerome Gambit game which should be routine and boring. Black makes a mistake on move 7, turning his clear advantage into a clear disadvantage. In fact, this had happened twice before in Bill Wall games, and they showed "1-0" in 10 moves or less (in a third game, Black struggled on for 10 more moves).

So, Bill takes his advantage and moves on to the win. Things were not that simple, though. Watch.

Wall, Bill - Anonymous
lichess.org, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 g6



It is fun, kicking White's Queen. However, this move gives up the Knight at e5 and the Rook at h8. (If you worry about being greedy, you can substitute capturing the Bishop at c5.)

8.Qxe5+ Kf7 9.Qxh8 

Here, Black resigned in Wall, Bill - DGTS, FICS, 2011

9...Qh4+ 10.g3

Here, Black resigned, in Wall, Bill - Guest1681797, PlayChess.com, 2013,

10...Qh3

Or 10...Qf6 11.Qxh7+ Qg7 12.Qxg7+ Kxg7 13.Nc3 d6 14.Nd5 Bb6 15.b3 Bg4 16.Bb2+ Kh7 17.Nxb6 axb6 18.Kf2 Re8 19.h3 Be6 20.g4 Black resigned, Wall, Bill - Guest862403, Play.Chess.com 2014.

11.d3 d5 

So, here we go. White is up the exchange and a couple of pawns. His Queen is a bit uncomfortable in the corner, at h8, however, and his King is not altogether safe. What to do?

12.Qe5 

Perfectly reasonable. Anyone who has ever seen Amateur - Blackburne, London, 1884 (see "Nobody expects the Jerome Gambit!" and "Jerome Gambit: Dr. Harding Checks In") would not wait for ...Nf6, locking in White's Queen.

Now, White goes on to win in three dozen more moves.

But - wait. Stockfish 10, recommends, instead, 12.f5!?, with a whole lot of crazy tactics -  12...Bxf5 (not 12...gxf5 because of 13.Nd2 dxe4 14.Nxe4!? fxe4 15.Rf1+ and attack) 13.Qe5 and the f-file will be trouble for Black, especially after ...Qg2 is met by Rf1. Just one example of play is 13...dxe4 14.Qxc5 exd3 15.Qxc7+ Kf8 16.Qc5+ Kg7 17.Nc3 Qg2 18.Rf1 dxc2 19.Be3 Re8 20.g4 Qxg4 21.Kd2 - and you can see why Bill simply chose to remove his Queen!

12...c6

Black supports his d-pawn - but Stockfish 10 will have none of it. To keep only about a three-fourths of a pawn behind, Black should try 12...Qg2 13.Rf1 Bg4!? 14.Qxd5+ Kg7 15.Nc3 b6!? when 16.f5 Nf6!? 17.Qc4 (not 17.Qxa8? Bd4! with a forced mate) Qxh2 18.d4 Qxg3+ 19.Rf2 Qg1+ 20.Qf1 Qxf1+ 21.Rxf1 Bxd4 22.fxg6 hxg6 23.Nb5 Be5 24.Bf4 Bxf4 25.Rxf4 g5 26.Rf1 Nxe4 27.Rg1 Nf6 leaves Black with a pawn for the exchange...

So - Black's choice of a move is understandable, too.

13.f5 gxf5 14.Nd2 Nf6 15.Nf3 Qg2 16.Rf1 Qxc2 



It is humorous to point out that Stockfish 10 sees White as being the equivalent of 4 pieces ahead. I am not sure that Bill's King felt that way!

17.Ng5+ Kg7 18.Bd2 Qxd3 19.exf5 

This will support White's Knight when it comes to e6. For sheer madness, take a look at 19.Rf3 Qc4 20.Rf4 

19...h6 20.Ne6+ Bxe6 

21.fxe6

This is fine, altough Stockfish 10 recommends 21.O-O-O!? Qc4+
22.Bc3 Bd4 23.Qxd4 Qxd4 24.Rxd4 Bg8 when White would still be up the exchange.

21... Bd4 22.Qc7+ Kh8 23.O-O-O Qc4+ 24. Kb1 Ne4 25. Bc1 Qb4 

26.e7 

Cold blooded. Others might have returned the exchange with 26.Rxd4 to deal with one threat to b2, or tried 26.Ka1 to avoid the nasty 26...Nc3+ fork. Instead, Bill enlists the "Jerome pawn" in his checkmate threats.

26... Nc3+ 27.Ka1 Nxd1 28.Qd8+ Rxd8 

Abject surrender, although 28...Kh7 29.Rxd1 Bg7 30.Qxa8 Qxe7 would also leave him a Rook down. 

29.exd8=Q+ Kg7 

30.Qd7+ Kh8 31.Qe8+ Kh7 32.Rf7+ Bg7 33.Qd7 Qd4
34.Qf5+ Kg8 35.Re7 Qf6 36.Re8+ Kf7 37.Qh5+ Qg6 38.Re7+ Black resigned

He will soon be down a Queen for a few pawns.

Jerome Gambit: My Opponent Knows What He Is Doing (Part 1)





While it looks like I am headed for a 3rd place finish (out of 6) in the 3rd round of the "Italian Battleground" tournament at Chess.com, I will at least have some Jerome Gambit tales to tell from the experience.

I have already shared my 3rd round game perrypawnpusher - Abhishek29, "Italian Battleground", Chess.com, 2019 (1-0, 35) - my second win in this tournament against that opponent, having defeated him in in Round 1 - see perrypawnpusher - Abhishek29, "Italian Battleground", Chess.com, 2019 (1-0, 19).

The current game is a rematch with an opponent that I faced in Round 2 - see perrypawnpusher - warwar, "Italian Battleground", Chess.com, 2019 (1-0, 39). I was a bit concerned, the way "real" chessplayers are concerned about "real" chess openings: how much had he learned about the Jerome Gambit in the meantime?

It turned out to be an interesting battle between the "Jerome pawns" and the defender's extra piece, but, most of all, between someone who had prepared the opening and someone who had to improvise in the middlegame and endgame.

perrypawnpusher - warwar
"Italian Battleground", Chess.com, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




When the game was over, the Chess.com site offered to do a quick computer analysis. Not surprisingly, this move was labelled a blunder.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 



warwar adopts the Jerome Defense, first suggested by Alonzo Wheeler Jerome in his analysis in an article in the Dubuque Chess Journal of July, 1874. It was first played in Jaeger - Jerome, correspondence, 1880 (1-0, 40).

Interestingly enough, Abhishek29 was playing the same defense against me in the same round, too. My record, at that point, against the line was 25 - 6 - 3, a decent 78% score.

7.Qxe5 d6

As I wrote in the article that I had prepared for Kaissiber (unfortunately, never published)
The defenses 6…Kf8 and 6…Ng6 have had their supporters and detractors, depending on how each evaluated the alternatives – was it better to hold onto a little material and avoid complications, or to enter them confidently, knowing that they would turn the game even more in your favor? 
Jerome (DCJ 7/1874) first suggested 6…Kf8. He followed it with 7.Qxe5 d6 8.Qf4+ Nf6 9.c3 Kf7 10.d4 Bb6 11.e5 dxe5 12.dxe5 Re8 13.0-0 Kg8 14.exf6 Qxf6 15.Qxf6 gxf6 16.Bh6 “and White has a pawn ahead.” (Actually, the game is even; but Jerome missed that earlier his 11.e5 was premature, as after the pawn exchange 12…Qd3 would be crushing – Paul Keiser, personal communication. The alternative 8…Ke8 was seen in 5 games in the Yetman – Farmer 2008 match.) 
As Sorensen (NS 5/1877) did not mention 6…Kf8, it was not touched upon by other writers until Freeborough and Rankin (COAM, 1889) suggested that it led to a safe game for Black, giving the line 7.Qxe5 Qe7 8.Qf5+ Ke8 9.Nc3 d6 10.Qf3 Qf7 (or 10...Nf6!) 11.Qe2 Nh6 (or 11...Ne7 or 11...Nf6) with “a superior position or game” to Black. 
A hundred years after Jerome, Harding, in his Counter Gambits (1974), varied, after 7.Qxe5 d6 8.Qf4+ Nf6 with 9.d3 Kg8 10.Nc3 Qe8 11.Be3 Bb4 12.0-0 Be6 13.Ne2 Qh5 14.Nd4 Bd7 15.c3 Bc5, advantage to Black. His comment in The Italian Game (1977) was that after 7…d6, White was left “without genuine compensation for his piece.” He sagely recommended the 6…Kf8 line as “other lines would allow White to attack the exposed black king or to win back the sacrificed material.”

8.Qg3 

I experimented with Jerome's 8.Qf4+ in perrypawnpusher - Capt. Mandrake, Jerome Gambit 3 thematic tournament, ChessWorld.com, 2008 (1-0, 9) and perrypawnpusher - LeeBradbury, "Italian Game" Thematic, Chess.com, 2012 (1-0, 36).

I also tried 8.Qc3 in perrypawnpusher - Raankh, blitz, FICS, 2009 (0-1, 22).

There is not much difference in the strength between these two moves and the text, or even 8.Qh5, if Stockfish 9 is to be believed.

8...Nf6 9.Nc3 Kf7 

Abhishek29 chose 9...Be6 in our Round 3 game.

Years ago, perrypawnpusher - klixar, blitz, FICS, 2007 (1-0, 33) continued 9...Ng4.

perrypawnpusher - truuf, blitz, FICS, 2011 (0-1, 32) continued with the text move.

Jerome Gambit: Reassessing a Variation (Part 1)


I just completed my 3rd Jerome Gambit game in the first round of the "Italian Battleground" tournament at Chess.com. The win, making me 2 - 0 - 1 with my favorite opening, so far, should be enough to earn me first place in my group, and allow me to eventually move on to the second round.


perrypawnpusher - zmarian
"Italian Battleground" tournament, Chess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ 

Despite Alonzo Wheeler Jerome's early preference, and that of Bill Wall and others, I have only played 6.d4 once, and that game took a bit of a swindle for me to get a draw. To each one's own.

6...g6 

This move was not a surprise. The best known Jerome Gambit game, Amateur - Blackburne, London, 1884 (see "Nobody expects the Jerome Gambit!" and "Jerome Gambit: Dr. Harding Checks In") features this move, and if my opponent was likely to know anything about the opening, this would be it.

7.Qxe5 Bxf2+ 

A bit of a surprise - but not really.

Instead of offering a Rook with the Blackburne Defense, 7...d6!?, or preparing a wicked counterattack with Whistler's Defense, 7...Qe7!?, my opponent plays what I have elsewhere referred to as an "inoffensive defense" (see "An Inoffensive Defense") and a "calming defense" (see "Nothing Happened").

The Database has a surprising 1,375 games with this position, with White scoring 53%, which compares favorably with ther 46% produced by 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+. (Nine games are mine, with White scoring 89%).

In our first game in this tournament, we quickly moved to an endgame where I was a pawn up - but it took some fancy calculating to win the game. My opponent currently has fashioned a very interesting blockading position in one of his other games (he is a pawn down) and should soon split the point. So, to see our game move quickly to a Queenless middlegame, with the promise of an endgame, was understandable - zmarian likes endgames.

8.Kxf2

ZahariSokolov of FICS has played 8.Ke2?!, but I can't recommend the move: 8...d6? 9.Qxh8? Qf6? 10.Qxh7+Kf8 11.h3 b6 12.Rf1 Ba6+ 13.d3 Re8 14.Rxf2 Rxe4+ 15.Be3 Qxf2+ 16.Kxf2 Black resigned, ZahariSokolov - Posapiano, standard, FICS, 2015

8...Qf6+ 

Black did not improve things by playing 8...Qh4+ 9.g3 Qf6+ 10.Qxf6+ Nxf6 11.Nc3 Re8 12.d3 c6 13.Kg2 Kg7 14.Bg5 Ng4 15.h3 Nh6 16.Rhf1 d6 17.Rf2 Be6 18.Raf1 Rf8 19.Bxh6+ Black resigned, perrypawnpusher - Hensel, blitz, FICS, 2014.

9.Qxf6+ Nxf6 

The curious game perrypawnpusher - ronn, blitz, FICS, 2009, continued 9...Kxf6 Black resigned.

10.Nc3

I have played 10.d3 a couple of times, in perrypawnpusher - Edvardinho, blitz, FICS, 2010 (1-0, 42) and perrypawnpusher - Dubnobase, blitz, FICS, 2013 (1-0, 49).

10...d6 


Black has a number of replies. I have faced 10...Re8 a couple of times: perrypawnpusher - Conspicuous, blitz, FICS, 2011 (1-0, 22) and perrypawnpusher - BEEB, blitz, FICS, 2011 (1/2-1/2, 63).

(Oddly enough, I don't seem to have posted either of these games on this blog. I will have to remedy that.)

11.d4 

Playable is 11.d3, which I have tried a couple of times: AlonzoJerome - adroit, blitz, ICC, 2011 (1-0, 25) and perrypawnpusher - HelloGoodbye, blitz, FICS, 2012 (1/2-1/2, 34).

(You wouldn't have known it by this blog, though: two more games to find and post. What was going on in 2011 and 2012, I wonder.)

11...Bd7 

Interesting. Understandable was 11...Rf8, which I have also faced in perrypawnpusher - Mences, blitz, FICS, 2011 (1-0, 48).

(Also not posted here. Very odd. My "to do list" is growing.)

Jerome Gambit History Tidbits


A few of my recent Jerome Gambit discoveries...

Amateur - Blackburne, London, 1884
Stumbling over the infamous Jerome Gambit game Amateur - Blackburne, London in the Australian Town and Country Journal (Saturday, March 21, 1885, page 31) I found another comment that supported 1884 as the year of the game (as if there needed to be more than Dr. Tim Harding's words from the English Chess Forum, which I presented in "Jerome Gambit: Dr. Harding Checks In")
We reprint from the Adelaide Observer...The following affair occurred to the great blindfold player a few months ago in London... 
But the best part was the columnist's comment on the stunning move 4.Bxf7+: "So early in the morning!"


Emanuel Lasker, columnist
The Evening Post: New York  from Wednesday, November 30, 1910, (page 11) had Emanuel Lasker's "CHESS AND CHESS PLAYERS" column, including the following news
...At the rooms of the Rice Chess Club in the Cafe Boulevard, the team representing the Temple Chess Club of the Baptist Temple of Brooklyn encountered the team Stuyvesant High School, and, although handicapped by the absence of two players, causing forfeiture on two boards, the Brooklyn players carried off the victory by the score of 3 points to 2... The Temple Chess Club players had the white pieces on the odd-numbered boards. The Jerome gambit, king's bishop opening, and French defence were adopted at the last three boards...
Although the copy of the paper is at times difficult to make out, it appears that Board 3 was a match between E. E. Brodhead of the Temple C.C. and Gadiowitz of Stuyvesant H.S., with Brodhead's Jerome Gambit carrying the day. I have not yet discovered the game.

It should be recalled that Lasker, responding to a letter to “Our Question Box” in the March 1906 issue of Lasker’s Chess Magazine had already said his peace about the opening 
No; the Jerome gambit is not named after St. Jerome. His penances, if he did any, were in atonement of rather minor transgressions compared with the gambit.

Emanuel Lasker, Simultaneous Exhibition 
The Observer (Adelaide) of Saturday, December 29, 1906 (page 49) has in its CHESS column, under CHESS NOTES, the following
Simultaneous Chess. - Lasker, playing at Pittsburg, Pa., lately, out of 28 games won 24, drew 2, and lost 2, a fine score of 25-3. The openings adopted were varied - Sicilian Defence 3, Centre Gambit 5, Petroff 1, Evans 4, Four Knights 2, Vienna 1, Jerome 1, King's Knight 1, King's Gambit 5, French 2, Allgaier 2 and only 1 Ruy Lopez.

It would seem that the source of Observer column was the October 18, 1906 (page 9) Pittsburgh Press article titled "DR. LASKER PLAYED 26 GAMES OF CHESS AT ONCE.  He Succeeded in Winning 22 of Them and Drawing 2." It is unclear why the two news reports differ in the number of games reported being played and won; and the Pittsburgh Press names 27 club members who were seated against Lasker, so apparently at least one board was covered by two players.

The Jerome Gambit (neither a win nor a draw for White) was played by E. H. Miller. (This is likely Emlen Hare Miller, who, a decade later, had a win [opening unknown] against Frank J. Marshall in a simultaneous exhibition.)

Of note
Before the contest began Lasker made an address on "The Game of Chess and the Game of Life," which was highly appreciated by his listeners.
How I would love to discover how Lasker defended against the Jerome Gambit!
  
Beware, chess students, the dreaded Jerome Gambit
The Telegraph (Brisbane) of Saturday, December 14, 1929, (page 13) had a "CHESS" column that gave the Jerome Gambit a greater sense of scariness than I had realized it had ever projected   
Chess students are early taught to watch out for the dreaded Jerome Gambit, an attack however that owes its success mainly to the inexperience of the attacked. Unsound it undoubtedly is, but white obtains a ferocious offensive requiring on the part of black the very greatest care. An ounce of practice, we are told, is worth a ton of theory, so the following game in the case isoffered. It is a win by the famous Blackburne with the black; of course it is not given to us all to be Blackburne...
