Jerome Gambit: Hot Mess


The Jerome Gambit is a strange opening.

Sometimes the lines assessed as "better" do not do as well as those assessed as "worse". 

It is not familar ground for many defenders, and that can lead to errors. Threats arise and complications abound. The mistakes are all there, ready to be made.

Play the Jerome Gambit at bullet speed, and it all adds up to a hot mess.

The following game illustrates.


SastoJugad - Bhulakand

1 0 bullet, lichess.org, 2023

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf6 


This is a naive attempt to hold onto the Knight at e5. Black is probably not familiar with the Jerome Gambit, and in a 1-minute game he does not have time to analyze deeply.

The Database has 345 games with this position, with White scoring 77%. 

7.d4

This move is good - it has two threats, one direct and one promised - but there is something better.

7.Qf5+ Ke7 8.Qxe5+ Kf8 9.Qxc5+ scoops up a couple of pieces and leaves White a couple of pawns ahead. Stockfish 15.1 sees White as the equivalent of 3 1/2 pawns ahead.

The Database has 137 games with the 7.Qf5+ line, with White scoring 77%.

The text move appears 23 times in The Database, with White scoring 87%, even though Stockfish 15.1 assesses Black to be 1 1/2 pawns better. 

Yes, White scores better with the weaker move. Probably because of the game continuation.

7...Bxd4 

Black sees the direct threat: What to do, what to do, what to do with the Bishop?

Not this.

The defender had 7...Bb4+ 8.Nc3 Bxc3+ 9.bxc3 Nf7, keeping his advantage. 

Now the game is won for White.

8.Bg5+ 

Ah, yes, the other threat.

8...Ke6 9.Bxd8 Black resigned

"Italian Game" Tournament, Round 2, Chess.com

  •                          

The second round of the "Italian Game" tournament at Chess.com (see "Jerome Gambit: The Battles Continue") has started, and I am matched against Seal Island Puffin, aansmar, and poorplayer63.

I have a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game going against Seal Island Puffin and aansmar. The first game should be especially interesting, as my opponent is rated 350 points higher than me.

Statisically, the only player I should be playing the Jerome against is poorplayer63, who is rated 127 points below me. We are playing a Philidor Defense.

We shall see how things turn out - and I will publish both games.

To Counter Jerome Gambit



The latest Jerome Gambit video that I have found on YouTube is by Chess Master ("I upload chess games that I played and show interesting moves") and is titled "How to counter jerome gambit".

Such videos are important for a number of reasons, not the least of which is to remind us that we play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) for fun and exploration - the opening is not in the repertoire of the current (or past) World Champion.

Also, since our opponents might be watching the same video, it is worth knowing a little bit about what he or she is preparing. 

Here is the line given in the short video, along with some suggested alternative moves, to get Readers started.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ (6.d4) 6...Ke6 7.Qf5+ (7.Qh3+) 7...Kd6 8.f4 (8.Nc3) 8...Kc6 9.Qxe5 (9.fxe5) 9...Nf6 10.d4 (10.d3) 10...d6 11.d5+ (11.Qg5) 11...Kb6
12.Qc3 a5 13.Qb3+ (13.Be3) 13...Ka7 14.Be3 Nxe4 15.Nxe4 Re8 16.Qd3 Bf5 17.Bd2 Nxe4 15.Na3 (15.Nd2) 15...Qh4+ 16.g3 Qh5 17.Bxc5+ (17.O-O) 17...Nxc5 18.Nb5+ (18.Qc4) 18...Kb8 19.Qc4 Re8+ 20.Kd2 Qf3 21.Rhe1 Re4 22.Qc3 (22.Qf1) 22...Qf2+ 23.Kd1 Bg4+ 

By the way, for an unorthodox opening that is in the repertoire of the top chess player in the world, perhaps also for fun and exploration, check out the video 
with the black pieces in a 3-minute game, and defeats Vladimir Kramnik in 31 moves.

Jerome Gambit: Cooperation Helps




When pieces cooperate, in an attack or on defense, they are more likely to be successful in their task.

One of Black's difficulties in the following game is that his pieces do not always cooperate. 

That is enough for Bill Wall to make his way to victory.

Wall, Bill - Bansal

internet, 2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 N8e7


Interesting, but not as strong as the more routine 9...Nf6.

10.d3 

Instead, 10.O-O Ne5 11.d4 Nf7 12. f4 was seen in Wall,B - Godoy, internet, 2022 (1-0, 29). 

10...b6 11.O-O Bb7 12.f4 Rf8 

White's pawns look like they are ready to advance toward Black's King, still stuck in the center.

Black has an extra piece for those two pawns, however, so the game is pretty well balanced.

13.f5 Ne5 14.Na3 

The Knight starts on a tour.

14...Rf6 

The first start of castling-by-hand!

15.Nb5 Kf8 16.Qg3 Kg8 


17.Nd4 

White also had 17.Bg5, but his Knight wanted to continue its travels. 

17...Kh8 18.h4 c5 19.Ne6 Qg8 20.Nc7 Rc8 21.Nb5 a6 


22.Nxd6 Rxd6 23.Qxe5 Rd7 24.f6

Chasing the annoying Knight.


To open the f-file for his Rook.

24...Ng6 25.Qf5 gxf6 

An oversight, the kind of thing that can happen when under pressure.

Black could have tried to hold on with Stockfish 15.1's suggestion of 25...Rf7, but the following possible line of play is not encouraging: 26.fxg7+ Rxg7 27.Bh6 Nxh4 28.Qf6 Ng6 29.Rf2 Rc6 30.Bxg7+ Qxg7 31.Qd8+ Qg8 32.Qd7 Qc8 33.Qf7. White's Rook and 2 pawns are worth more than Black's two pieces. 

26.Qxd7 Bc6 27.Qd6 c4 28.Bh6 Black resigned


Black's pieces are still not cooperating.

Jerome Gambit: Does Not Rhyme With "Orange"

 


I received a Google Alert that had been set to notify me of internet appearances of "Jerome Gambit".

What I found was the following, from the page RhymeZone: Jerome Gambit.

Yes, indeed, someone before me was looking for words that rhyme with "Jerome Gambit".

As people say about the Jerome - "Good luck with that!"

Jerome Gambit: Breathless


Sometimes, playing over 1-minute games by angelcamina leaves me breathless...

I don't know how he does it: winning consistently with the Jerome Gambit, at bullet speed.

Not the strongest continuation.

Best is 9...Qe5 10.g3 Qh5 11.h4 Qxc5 and Black is better.

Of course, in 1-minute games, that can change in an eye blink.

10.cxd6 cxd6 11.f3 Ne5 

12.f4 

The pawn advance is thematic, but so is 12.Bg5, which is a bit stronger. At the speed that this game was played, it probably did not matter.

12...Neg4 13.h3 Nh6 14.e5 

14...dxe5 15.fxe5 Qxe5 16.Bxh6 gxh6 

17.Rxf6+ 

Continuing the aggression.

It turns out that the strongest move was - to exchange Queens?!: 17.Qd5+ Qxd5 18.Nxd5 Kg7 19.Nxf6 and White is winning.

17...Qxf6 18.Qd5+ Be6 19.Qxb7+ Kg6 20.Rf1 


A Rook down, White has to keep the pressure on.

20...Qd4+ 21.Kh1 Qd6  

What piece to move? What square to protect? The clock is ticking! Moving a Rook to f8, or the Queen to e5, was the way to continue.

22.Ne4 

White has his next move planned, but this one only leads to an even position. The Queen should go to e4.

23...Qd5 

If only there was time to exchange Queens...

There isn't.

Black's Queen would do double defensive duty at d7, allowing his King to retreat to g7 after the upcoming check. Then the second player would have the advantage.

23.Rf6+ Kh5 24.Ng3+  Kh4 25.Qg7 Rhg8 26. Rf4+ Bg4 27.Rxg4 checkmate


Whew!

Jerome Gambit: Think Fast!



To succeed at chess at bullet speed - 1-minute chess - it is helpful to have a good eye for tactics.

The following game, from regular contributor angelcamina, is a good example.

angelcamina - Farbic

1 0 bullet, lichess.org, 2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Nxe4 5.Bxf7+ 


The Noa Gambit, the Monck Gambit, or the Open Italian Four Knights Jerome Gambit. If Black had been expecting 5.Nxe4 d5 6.Bd3 dxe4 7.Bxe4 Bd6 with a quiet position (although he would have to look out for Yury V. Bukayev's recommendation, 8.Bxc6+) this may have come as a surprise.

5...Kxf7 6.Nxe4 d5 

7.Neg5+ 

Or 7.Nc3 e4 8.Ng1 Bc5 9.d4 Bxd4 10.Nge2 Bb6 11.O-O Rf8 12.Nxd5 Kg8 13.Nxb6 axb6 14.Qe1 Ne5 15.Qc3 Qf6 16.Bf4 Ng4 17.Qxf6 Nxf6 18.Bxc7 Bg4 19.Ng3 Rac8 20.Bxb6 Rxc2 21.Bd4 Rd8 22.Bc3 b5 23.a3 Rd3 24.h3 Be6 25.Rad1 Bb3 26.Rxd3 exd3 27.Rd1 Bc4 28.Ne4 Nd5 29.Nd2 Nxc3 30.Nxc4 Rxb2 31.Rxd3 Nd1 32.Kh2 Rc2 33.Rd8+ Kf7 34.Ne3 Nxe3 35.fxe3 Rf2 36.Rd7+ Kg6 37.Ra7 White won on time, angelcamina - florianschreib, 1 0 bullet, lichess.org, 2019.

8.d4 h6 9.Nh3 e4 10.Ne5 


The light-square Kingside weaknesses make Black's monarch a bit uneasy.

10...Nxe5 11.Qh5+ 

It is not clear if White overlooked Black's next move, or if he decided to mix things up, hoping to find advantage down the line.

11...Nf7 12.Nf4 Qf6 13.Nxd5 Qd6 14.Bf4 Qc6 

A slip. It can happen at such time controls.

15.Nxc7+ Ke7 16.Nd5+ Ke8 17.Nc7+ Ke7 

Repetition saves time for both players and gives a few more seconds for reflection. angelcamina does not want a draw.

18.Nxa8 Qxc2 

Black's Queen will not do as good a job harassing the White King as White's pieces will in harassing the Black King.

19.O-O Be6 20.Rac1 Qxb2 21.Rc7+ Ke8 22.Rxf7 Bxf7 23.Qe5+ Be7 Nc7+ Kf8 

25.d5 

This move gives Black the opportunity to exchange Queens, which he should have taken. The Queens come off the board shortly, but it costs more.

25...Qb6 26.d6 Qxd6 27.Qxd6 Bxd6 28.Bxd6+ Kg8 

White's extra piece and better placed Rook now create tactics to finish the game.

29.Rc1 Bxa2 30.Nb5 a6 31.Nd4 Kh7 32.Rc7 Rd8 33.Be5 b5 34.Rxg7+ Kh8 35.Rd7+ Black resigned
