Jerome Gambit: Computers Can Be Both Helpful and Annoying

The following Jerome Gambit blitz game arrived with notes from the chess site's computer. Often, the computer analysis is helpful. Sometimes, however, it just highlights the differences between silicon and human play.

CasualGames4ever - lankesh1941
10 0 blitz, lichess.org, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




The lichess.org analysis engine labels this move a "Blunder". Well, yes, technically it is. However, in human vs human blitz play at the club level, it is more of an invitation to interesting play!

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



The engine labels this an "Inaccuracy", which is a bit harsh. The move is played frequently and keeps Black's piece for two pawns advantage.

7.Qd5+ Ke7 8.Qxc5+ d6 9.Qe3



9...Be6 

The know-it-all chess engine calls this a "Blunder". It allows White to play 10.f4, with the threat of f5, forking Black's pieces.

10.d4 Kf8 11.Nc3 12.f4 Re8 13.O-O Bf7 



Black says: Come and get me!

Any Jerome Gambit player would oblige.

14.f5 Nh4 15.Qg3 h6

Planning something drastic.

16.Rf4 g5

This would work, if White couldn't capture en passant.

17.fxg6 Nxg6 18.Qxg6 Qe6 19.Qxe6



The cranky computer doesn't like this move, but it is perfectly reasonable: White is playing a blitz game, and he is happy to move on to a Queenless middlegame two pawns up.

19...Rxe6 20.d5 Rg6 21.Nb5 c5 22.Nxa7 Nf6 23.Nb5 Rhg8 24.Nxd6 

Cold-blooded. White's Knight has been collecting pawns, even though this means that his King will have to take a vacation on the Queenside. Perhaps the clock was beginning to influence play?

24...Rxg2+ 25.Kf1 Rg1+ 26.Ke2 Bh5+ 27.Kd3 Rd1+ 28.Kc4 Ke7



White is still winning, but he is no longer comfortable.

29.Kxc5 

A slip, as Black can now kick the enemy King away with 29...Nd7+, and then grab the Knight. Instead, 29.Nf5+ Kd8 30.Ne3 would have consolidated his position and won more material.

It definitely feels like the clock is affecting both players, now.

29...Rgg1 

To win the Bishop, of course.

30.Nc8+ Kd7 31.Rxf6 Kxc8 32.Be3 Rxa1 33.Bxg1 Rxg1 34.Rxh6 

Whew! White now has 5 pawns for Black's extra piece. Push those pawns!

34...Bd1 35.e5 Bxc2 36.e6 Rg6 37.Rxg6 Bxg6 38.d6  Bf5 39.Kd5 Bh3 40.a4 Bg2+ 41.Ke5 Kd8 42.b4 Bc6 43.b5 Bf3 44.a5 Be2 45.a6 bxa6 46.bxa6 Bxa6 



47.h4 Ke8 48.h5 Bd3 49.h6 Bc2 50.Kf6 Kf8 51.d7 Black resigned



Another victory for the "Jerome pawns"!

Jerome Gambit: Settle Down and Work A Bit

Not every Jerome Gambit game is a quick smash. Sometimes the attacker has to settle down and work a bit - even in a blitz game. The following game is a good example.

spicyindianswag - AyujVerma
3 2 blitz, Chess.com, 2020

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




 4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8



A safe move. White will recover a piece. Then he will need a plan.

7.Qxe5 d6 8.Qf4+ Nf6 9.c3 



White will extend his pawn center. Meanwhile, Black will return some material and castle-by-hand.

9... Kf7 10.d4 Bb6 11.O-O Rf8 12.e5 dxe5 13.dxe5 Kg8 14.exf6 Qxf6 

Often I talk about psychology in the Jerome Gambit: how the defender can be surprised or become anxious, or become over-confident and dismissive. This can affect his move choice in a bad way.

Black wields his own psychology here: his King is safe, and he wants to exchange Queens. Sure, he will be a pawn down, but with the two Bishops, he can resist for a long time. In the meantime, White has to deal with the disappointment of his attack disappearing.

15.Qc4+ Be6 16.Qd3 

Suddenly, it appears that Black's development is overwhelming. Can he punish White? Remember, this is a 3-minute game.

16...Bxf2+ 17.Kh1 Bf5 

This is why we study chess puzzles to get better. Komodo 10 suggests 17...Rad8 18.Qe2 Bd5 19.h3 Rde8 20.Qg4 Bg3 21.Bf4 Qxf4 22.Qxf4 Bxf4 and White's game has become very painful.

But - White now wriggles his way out!

18.Qf3 Bd7 19. Rxf2 Qxf3 20. Rxf3 Bg4 21. Rxf8+ Rxf8



If you strike at the king, you must kill him.

Black had his chance against a higher-rated opponent, but that time has passed quickly. Now White has the extra piece.

22.Kg1 c5 23.Be3 b6 24.Nd2 a5 25.Rf1 Re8  26. Re1 Re5 27.Bf2 Rd5  

Black does not want to exchange pieces, but, as White's pieces come into play, the danger increases.

28.Ne4 b5 29.Bg3 b4 30.Nd6 Bh5 31.cxb4 axb4 32.Nc8 Kf7 


Like in a scary movie, we want to say "No! Don't leave the house!"

33.Nd6+ Kf6 34.Bh4+ g5 35.Ne4+ Kf5 36.Ng3+ Kg4 37.Re4 checkmate

Very nice!

Jerome Gambit: I Am Not Encouraging "Perfect Chess"

By promoting the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ ) I am not encouraging "perfect chess" for masters and grandmasters. Rather, I am supporting enjoyable and educational chess for amateur and club players.

The following game shows that while Black might be able to "solve" the Jerome Gambit, if he has enough time - a 3-minute blitz game is often not enough time. jamezad's attack flows like running water.

jamezad - loganwrites

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ Kf8 8.Qxc5+ Ke8 9.d4 



According to The Database, this is a novelty - at move 9.

9...d6 10.Qc4 N8e7 11.O-O Qd7 12.Nc3 Rf8 13.Bg5 Nc6 14.e5



White offers a pawn to open central lines against Black's King and Queen.

14...dxe5 15.dxe5 Ncxe5 16.Rfe1 Rf5



Both protecting the Knight and attacking the enemy Bishop, but he begins to let the game slip away. 

17.Qg8+ Nf8 

Instead, the Rook needed to return, but it can be hard to undo what we have already done. White now completes the lesson.

Please Read

About a week-and-a-half ago, I started getting emails suggesting that I check out a certain online link. It led to a video of a program originally on Twitch that had taken up residence on YouTube.

In it, a grandmaster was having a humorous time with the Jerome Gambit, this blog, and me. That wasn't much of a surprise - except that most top players would not give the Jerome even a second glance, while the video was 17 minutes long.

So, everyone in the video, including those in the scrolling comments - and, later, those who commented in YouTube - had a good laugh at a chess opening that was probably refuted shortly after it was first played. The Jerome Gambit certainly had a great future behind it.

Okay. 

A video lampooning a blog running for 12 years, posted to every day or every-other-day on that bizarre opening? Are you kidding? Hilarious.

Okay.

The amusement grew. For real, a weird guy who has been researching the Jerome Gambit for a couple of decades, and keeping that blog up-to-date? I mean, come on, does he actually think that it's a good opening?

The grandmaster just had to play some Jerome games online, and then send one to me, borrowing a username and changing his rating. Would it wind up posted on the blog? It was! Untold amounts of  ROTFL!

Okay, too.

The guy was funny. He got into the Jerome Gambit with bravado, looking like its second-biggest fan. He had played fair with me, too - when he sent his game to me, it was in an email with his own name on it. I figured something was up.

Then, Pepe the Frog made an appearance in the video. Originally in Matt Furie's comic, "Boy's Club", the character was later adopted by far-right groups to espouse their causes, much to the creator's embarassment. Despite claims that the anthropomorphic amphibian has been white-washed back to decency, for a lot of people today, the meme still screams hatred and prejudice.

Not okay.

About that point in the video, things started getting awkward, as when the GM was trying to play a game online, and exclaimed  "Dammit, I'm black.... Maybe it works for black as well. I mean it is called the Jerome". Huh?

Then came a brilliant suggestion that Jerome might have originally blundered away a couple of pieces, and then just claimed that he had invented a new opening. Good stuff - if it hadn't been voiced in a stereotypically offensive imitation of a Black person's voice. Not much later, there was an energetic lampooning of the "privilege" that the Jerome, with the white pieces, was all about. The observers in the comments caught it all, and loved it, too.

It took me several runs-through, with CC, to catch much of it.

It was not okay.

Why spoil a surreal chess performance, with such racist offensiveness? What a sense of timing. With with what seems like an endless string of killings of Black people in this country - the most recent, of George Floyd - and the widespread protests of endless police violence being met with more police violence, was any of that necessary? Is it ever necessary?

No.

Even if our prejudices cling to us like a shadow we can't outrun - we can try.

Imagine my excitement at getting an invitation to join the grandmaster on his chess show this week, via Zoom, to further discuss the Jerome Gambit -  that passion of mine for 20 years.

Imagine my disappointment, too. 

Of course, I declined the offer.

Jerome Gambit: Everything Happens Quickly


White is new to the Jerome Gambit, but you would not be able to tell that from the way that he quickly finishes off his opponent. Of course, in a 1-minute game, everything happens quickly.

JuiceCisario - piolhorov
1 0 bullet, lichess.org, 2020

1.e4 e5 2.Bc4 Bc5 3.Nf3 Nc6 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Nh6 



In bullet chess, what first comes to mind is often what gets played. Here, Black thinks Hit the Queen! and goes with it.

White calmly decides to Hit the King!

9.Qxe5+ Kc6 10.Nc3 Re8 



This was Black's last chance. He should have tried 10...d6, instead.

11.Qd5+ Kb6 12.Na4+ Kb5 13.Qxc5+ Kxa4 14.b3 chekmate



Very nice.

Jerome Gambit: Quick Finishes


I have received a number of Jerome Gambits that show clearly why players are drawn to it - the sacrifice shows up in a variety of lines, and the games feature quick finishes. Take a look.

In his first Jerome, Kylon tries what I have begun to call an "impatient Jerome Gambit" (White doesn't wait for ...Bc5) against the Hungarian Defense. In this case, impatience is rewarded, with a checkmate in 9 moves.

Kylon - PawnStar10111
3 0 blitz, lichess.org, 2020
1.e4 e5 2.Nf3 Nc6 3.Bc4 Be7 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.d4 Nc4 8.Qf5+ Kd6 9.Qd5#

Rawnessman applies the Jerome treatment to the Two Knights Defense, in a 1-minute bullet game. His aim is true.

The_Guccinator does not let his opponent hide in the Petroff Defense. A Jerome-inspired sacrificial attack brings mate in under 10 moves.

Things did not go exactly as planned for Jean_Kn's opponent in the following game. At least the suffering was short.

Changing sides of the board, Jean_Kn plays a reversed Jerome Gambit, also know as the Busch-Gass Gambit or Chiodini's Gambit.

DropBearMKJ's first Jerome Gambit turned out better than he expected, and certainly better than his opponent had hoped.

Here we have another Two Knights that gets ambushed by an impatient Jerome Gambit. I think we've seen this kind of ending position before.

Jerome Gambit: To b or Not To b

The fate of Black's b-pawn overshadows much of the following game. It never falls - but the defender's attention is distracted enough that White makes progress elsewhere and slowly overwhelms the position.

Wall, Bill - Guest173767
PlayChess.com, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qxc5 d6 8.Qd5+



8...Ke8 


Yes, Black can offer the b-pawn with 8...Be6. This was seen in Wall, Bill - CheckMe, Chess.com, 2010 (1-0, 23) and Wall,B - Guest249301, PlayChess.com 2013 (1-0, 30).

There are other ways to decline:

8...Ke7 as in Wall,B - Guest4395, Internet, 2001 (1-0, 18) and Wall,B - Guest3157671, PlayChess.com, 2014 (1-0, 28); and

8...Kf8, Wall,B - Chung,J., Chess.com, 2010 (1-0, 25).

9.d3

Or 9.d4 as in Wall,B - Am53, PlayChess.com, 2013 (1-0, 14) and Wall,B - Guest7665109, PlayChess.com, 2019 (1-0, 22).

9...h6

Or 9...c6 in Wall,B - Seven11, Chess.com, 2008 (1-0, 51).

10.O-O c6 11.Qb3 Qf6 

12.Nc3 b5 

Still worrying about the b-pawn possibly falling to the enemy Queen.

13.a4 Rb8 14.axb5 cxb5 15.Rxa7 Be6 



Can you feel it? The weather is changing...

16.Qb4 Bd7 17.Nd5 Qf8 18.Nc7+ Ke7 19.f4
Black resigned

Black is feeling the Rook's pressure along the 7th rank, and will soon face more uncomfortable line-opening with e4-e5, plus the annoying f4-f5. It is all too much.
