Jerome Gambit: Often A Lot of Fun


One thing I like about Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games is that they often appear to be a lot of fun.

The following game, while not a Jerome proper, was clearly inspired by the Gambit. I suspect that for the winner it was plenty of fun.


cinna banana - NN

10 0 blitz, Chess.com, 2020


1.e4 b6 2.Nf3 Bb7


Owen's Defense.

3.Bc4 

An offer of a pawn, best declined.

3...Bxe4 4.Bxf7+ 


Logical. Komodo 11 likes it, too.

4...Kxf7 5.Ne5+

Instead, 5...Ng5+ would fork the King and Bishop, and win back the sacrificed piede - but White is thinking about checkmate.

5...Ke8 6.Qh5+ Bg6 


Black's best defense was to block the check with 6...g6.

7.Nxg6 Qc8 

Giving the King some breathing room. In such positions it is always wise to examine a move like 7...Nf6, which would prove more helpful in the current situation. Now the game is pretty much over.

8.Nxh8+ Kd8 


9.Qf7

This is a blitz game. This move wins. When White goes over his moves, afterwards, he will find an idea worth remembering: 9.Nf7+ Ke8 10.Nd6+ Kd8 11.Qe8# 

9...Nf6 10.Qxf8+ Ne8 11.Nf7 checkmate


Very nice. And funny.

Beating Beth Harmon With the Worst Opening Ever


Reader Marco Zanin sent me the link I Beat Beth Harmon with the WORST OPENING EVER - YouTube.

"The worst opening ever" of course, being the Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+.

The video features Jonathan Schrantz, a teacher in St. Louis, Missouri, who can be found at 

https:/www.twitch.tv/vampirechicken and

https://www.youtube.com/channel/UCIh4QOvH7v8eQNdUb2As9VA

Beth Harmon is the main charcter in Walter Tevis' novel The Queen's Gambit (1983) which was recently made into a series at Netflix. 

The online site Chess.com, where Schrantz can also be found, has a selection of computer-based personalities, i.e. "bots", that can be played against. There is a series of Beth bots, running from Beth (age 8) rated 800, up to Beth (age 22) rated 2700.

Schrantz delights in playing offbeat openings against bots, and for his game, of course, he chose to face the top-rated Beth (22).

The game lasted 32 moves, and immediately leaps into the top 25 Jerome Gambit games, ever; likely it makes it into the top dozen.

I will probably analyze the game in a future post, but I would like you to watch the excitment as it unfolds in the video. Schrantz has done the work, and he should get the attention.

Jerome Gambit: Killer Shrews!?



Here is the latest Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game from intrepid "Cliff Hardy". The notes are by Cliff. I have added diagrams and the occasional comment, in blue - Rick 

Enjoy!


I had a Jerome Gambit blitz game recently where the Jerome pawns attacked like killer shrews (my allegorical inspiration may have come from the fact that late last night I was watching the 1959 film "The Killer Shrews" on local TV).


Cliff Hardy (2251) - NN (2212)
5 0, Lichess, 4/12/2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6?!


Other defences like 6...Kf8 or 6...Ke6 are better.

[According to The Database, Cliff was 11 - 2 against this defense before this game. He should have been pretty comfortable with his play - Rick]

7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Nf6 


10.0-0 Qe7 11.Nc3 c6 12.d4 Kg8?! 


A creative unusual journey for the king but the more usual 12...Kf7, intending to artificially castle by ...Re8 and ...Kg8, would have kept an edge for Black.

13.f4 h6 14.f5 Nf8 15.Qf3 Bd7 16.g4??


White neglects development and this means that if Black were to play 16...Re8 -++ now, White could then only defend the e-pawn by playing Re1, but White really needs this king's rook on f1 to support a future push of the f-pawn. The much better 16.Bf4 ++-, intending to answer 16...Re8 with 17.Rae1, would have left White in a strong position to push through the Jerome e- and f-pawns, with rooks behind both pawns.

16...N8h7 17. h4 Re8 18. Re1 Qf7 19. Bf4 d5 20. e5 Ne4??


Stockfish says that Black should sacrifice the knight for the oncoming pawns with 20...Nxg4! 21.Qxg4 Bxf5 -++ but Black underestimates the power of the white e- and f- killer shrew pawns. Both of those killer shrews now get shot, but White still has other killer shrews lurking.

21.e6 Bxe6 22.fxe6 Rxe6 23.Nxe4 dxe4 24.Rxe4 Rxe4 25.Qxe4 Nf6 

[White is a pawn up, has a bishop vs a knight, and a freer rook. He is better. - Rick]

26.Qf5 Nd5 27.Qxf7+ Kxf7 28.Rf1 Kg6 29.Be5 Ne3 30.Rf4?? +=


Much stronger would have been 30.h5+! Kh7 (30...Kg5?? 31.Bf4+) 31.Rf7 Rg8 32.Rxb7 ++-, when White's rook would have been much  more active than its black counterpart.

30...Nxc2?? ++-

This may appear to be a logical move but it risks Black's king getting caught in a mating net. Preventing White from advancing his h-pawn by blocking it with his own with 30...h5! would have kept Black in the game.

31.h5+ Kg5 32.Kg2 Re8 33.Kg3 Rxe5??


Black spots that White intends to checkmate by playing Rf5, but he could have limped on by preventing that move by playing 33...Ne3! (not 33...g6?? 34.Bf6 mate), intending 34.Rf3? Nxg4.

34.dxe5 g6 35.e6 gxh5 36.gxh5 Ne3 37.e7 Nd5 and Black resigned


Unfortunately, Black resigns just before allowing the killer shrew on the seventh rank to mutate and savage viciously with 38.e8=Q Nxf4 39.Qe5 mate.

Jerome Gambit: It All Adds Up



When you have played over 500 Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games, it is a good bet that you know what is going on, what your choices are, and what your opponent's choices are. This, in turn, makes the "1-0" come easier.

Alonzo Wheeler Jerome played this move a few times, although he preferred 6.Qh5+. The Database - which reflects my research, and certainly does not have all of AWJ's games - shows his record with 6.d4 as 1-0-1 with 3 unfinished games. It shows his record with 6.Qh5+ as 
5-10-1, with 3 unfinished games.

The Database points out that Bill Wall has played 6.d4 in 312 games, scoring 92%, while he has played 6.Qh5+ in 226, scoring "only" 89%.

He could also have supported his Knight in its post with 7...d6.

Returning to his post, and harassing the enemy Queen while he is at it.

This does not look right. Best was probably to return the Knight to f6 and surrender a piece, i.e. 13...Nhf6 14.exf6 Nxf6.

14.Rxf4+ Kg8 15.Qb3+ d5 16.exd6+ Black resigned



It is checkmate next move.

Jerome Gambit: One Way Out

 

The following Jerome Gambit is interesting in that it shows the defender, under pressure, sacrificing a piece for a position that keeps a draw in hand, while producing all sorts of difficulties for his opponent - unless his opponent finds the one move that allows him to escape and go on to win.

The Database shows 627 games with 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ played by Bill Wall, and he scores 91%. 


Wall, Bill - NN

lichess.org, 2020


1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 


As I have mentioned in an earlier post (see "Jerome Gambit: What About the Rook?") when Black plays this move he commits himself to sacrificing a Rook - it is the main idea behind both the Blackburne and Whistler defenses.

Serious defense requires knowledge of this, as an alternative strategy - Kick the enemy Queen with a pawn, and figure the rest out later - tends not to work too well.

7.Qxe5 Nf6 

Black protects the Rook, giving up the Bishop, instead. It is worth referring back to "Jerome Gambit: e-File, Friend or Foe?"

By the way, there are 879 games in The Database with 7...Nf6; White scores 63%.

8.Qxc5 

Here Black resigned in Wall - Guest3151819, PlayChess.com, 2014. He might have tried the trap 8...Nxe4 9.Qd5+ Kg7 hoping for 10.Qxe4 Re8, winning White's Queen. Years ago, Bill side-stepped this with 10.f3 Nf6 11.Qd4 b5 12.d3 Bb7 13.Nc3 c6 14.Bf4 Qe8+ 15.Kd1 d6 16.Ne4 Rf8 17.Bxd6 Qe6 18.Bxf8+ Rxf8 19.Qxa7 Nxe4 20.Qxb7+ Rf7 21.Qb6 Nf6 22.Re1 Qc8 23.a4 Qa8 24.b3 Nd5 25.Qd4+ Nf6 26.axb5 Qb7 27.bxc6 Qxc6 28.Ra7 Rxa7 29.Qxa7+ Kh6 30.Qe3+ g5 31.Qe7 Kg6 32.Re6 Black resigned, Wall,B - Sigmon,A, lichess.org, 2012

8...Qe8 


9.d3 

Sensible. Possible was 9.e5 Qd6 10.0-0 Nd5 11.Nc3 Nxc3 12.Qxc3 Re8 13.d4, but Bill is content to keep things simple: he is up two pawns.

9...d6 10.Qxc7+ Bd7 11.Qxd6 


11...Nxe4 

Hoping to stir up some trouble. At first I thought that 8...Qe8 might have been a mouse slip, intending, instead, 8...Qe7, but this might have been Black's plan all along.

12.dxe4 Qxe4+ 


After a long think, Stockfish 11 suggests that now 13.Kd2 would lead to a draw by repetion, initiated by Black, while all other moves -except one - would lead to a lot of pain and suffering for White, ending in checkmate.

Leave it to Bill to find that one exception.

13.Be3 

You found the move right away, right?

13...Rhd8 14.Nc3 Qxg2 15.O-O-O Black resigned


White is up a pawn and a piece, and, just as important, his King is safe.

Jerome Gambit: The Pawns Hold Their own

The following game is a pleasant contest between the extra "Jerome pawns" and the extra piece. Balance is maintained until the "33rd piece" intervenes - as it often does in a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) bullet game.

Jerome Gambit: Named...What?

 


The Jerome Gambit had experienced a series of names - some more serious than others.

When Alonzo Wheeler Jerome's analysis of his opening first appeared in the April 1874 issue of the Dubuque Chess Journal, the "New Chess Opening" was given an introduction

We have received from A.W. Jerome of Paxton, Ford county, Illinois, some analyses of a new move in the Giuoco Piano, first played by him, which we offer our readers as: Jerome's Double Opening

The editor of the Dubuque Chess Journal was impressed by the two sacrifices, 4.Bxf7+ and 5.Nxe5+, hence the "double" in the name.

Apparently, he was also interested in highlighting the Queen moves that the opening contained, such as 6.Qh5+, as the Dubuque Chess Journal of January, 1875 presented more of Jerome's analysis with the curious title "Queen's Gambit in Jerome's Double Opening". I have never seen that name again; but, see the Kentucky Opening, below.

The American Chess Journal of June 15, 1876 referred to the opening as "Jerome's Double Gambit". A few months later, November 1876, publishing a letter from Jerome, the ACJ referred to Jerome's "Double Opening". In a February 1877 article it simplified the name to "Jerome's Gambit".

A very powerful event reinforced that last name. Lieutenant Soren Anton Sorensen, writing in the May 1877 issue of the Danish chess magazine Nordisk Skaktidende - an article that subsequently was translated to English, French, Spanish and Italian (probably other languages as well) and was reprinted widely - gave his analysis of the opening, noting

The Americans call the game "Jerome's double opening," an allusion, probably, to the fresh sacrifice of a piece which follows at the next move, but we shall prefer to use the short and sufficiently clear designation, Jerome Gambit.

"Jerome Gambit", it was, after that, for the most part.

One subsquent attempt at renaming came in a review of  G. H. D. Gossip's book, Theory of the Chess Openings (1879), in the Huddersfield College Magazine of July 1879, where Thomas Long mused

We do not well know why this opening (a branch of the "Giuoco") is styled a gambit, as it consists in White sacrificing a piece on the fourth move, and Staunton in his Handbook defines a gambit as a sacrifice of a Pawn.

The Americans recognize the force of this by styling the opening "Jerome's double opening," although we don't quite see the meaning of this. How "double"? We think that the simple and natural definition of Jerome's Attack - as Cochrane's attack in the "Petroff" where a piece is also given up by White on his fourth move - would suffice.

"Jerome's Attack" does not seem to have been widely adopted, either.

One bit of renaming came with the publication of Mr. Blackburne's Games at Chess by P. Anderson Graham in 1899. Blackburne's notes to his famous game Amateur - Blackburne, London, 1884 included the mention, after 6.Qh5+

Note - I used to call this the Kentucky opening.

As I explored in "The Kentucky Opening (Part 1, 2, 3 and 4)", Blackburne was linking the aggressive Queen move - and, hence the opening - to 1.e4 e5 2.Qh5, which was analyzed in the May 1875 issue of the Dubuque Chess Journal, and titled the "Kentucky Opening."

However, the name has stuck, and you will occasionally see 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ referred to as the Kentucky Opening.

Of course, such an outrageous chess opening will have been called many light-hearted names over the years.

The July 13, 1917 issue of Western Mail of Perth, Australia, had a story referring to the opening as "The Verdun Gambit".

American chess legend George Koltanowski, as recorded in the September 1958 issue of the Precita Valley Chess Herald, referred to the "Ashcan Opening", riffing off the name of John E. Ishkan, who had played the opening in a tournament that Kolty had observed.

Editor Gary K. Gifford, in his Unorthodox Openings Newsletter #17, asked, fairly, "Jerome Gambit, or Jerome Gamble?"

Most recently, I have seen a YouTube video referring to the "Headless Chicken" opening.
