Jerome Gambit: Mis-Match



In a tournament with 250 players, there are bound to be rating mis-matches, especially in the early rounds.

That is pretty much the story of the following game. I like to think, though, that the Jerome Gambit helped add some confusion to my opponent's task.


perrypawnpusher - m2mkiss

"Giuoco Fun" tournament, Chess.com, 2023

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Ke8 

6.Qh5+ 

Not the strongest move, but I was hoping for complications.

Instead, 6.Nxc6 bxc6 7.Qh5+ g6 8.Qxc5 as in perrypawnpusher - rodrigojalpa, blitz, 2 12 blitz, FICS, 2008 (1-0, 25). 

6...g6 

Long ago:

6...Kf8 7.Qf7 checkmate, perrypawnpusher - platel, blitz, FICS, 2011;

6...Ke7 7.Qf7+! Kd6 8.Qd5+ Ke7 9.Nxc6+ Kf6 10.Qf5 checkmate, Kennedy - WeakDelphi, blitz 2 12, 2008 .

7.Nxg6 Qf6 

Stockfish 16 likes 7...Bxf2+, a move that is as old as Hultgren,R - Harrow, Campbell, CA 1960. 

8.Nxh8+ Ke7 

Or 8...Kd8 9.Qxc5 Qxh8 10.Qf8 checkmate, perrypawnpusher - schachix, 5 3 blitz, FICS, 2013.

9.Qxc5+ d6 10.Qc3 

At this point I was happy to exchange Queens. 

10...Ne5 11.Qxc7+ Bd7 12.Nc3 Qxh8 


White is up the exchange and 4 pawns. It is time to finish off the enemy King.

13.f4 Nc6 14.Nd5+ Ke8 15.Qxd6 Qg7 


Another day, another time, going after White's Rook at h1 might be a good idea. Right now, there is not enough time.

16.Nc7+ Kd8 17.Ne6+ Kc8 18.Qc7 checkmate

Jerome Gambit: Puzzling Draw



My first completed game in the ongoing Chess.com "Giuoco Fun" tournament came as a bit of a surprise - I guess I made the offer, and my opponent quickly accepted. That's what the site said, but I am hazy on the details...

You can look at the final position and decide which of us made the smart move.


perrypawnpusher - jackedU711

"Giuoco Fun" tournament, Chess.com, 2023

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Kf8 

Seen as early as Jerome - Brownson, Iowa, 1875, (1/2 - 1/2, 29) which appeared in the March 1875 issue of the Dubuque Chess Journal.

6.Nxc6 dxc6 


7.O-O 

I have also tried 7.Nc3 in perrypawnpusher - Ykcir, 14 0 blitz, FICS, 2009 (1/2 - 1/2, 11). 

Instead, 7.c3 was seen in Vazquez, A - Carrington, W, Mexico, 2nd match, 1876 (1-0, 43). 

7...h5 

Creative and aggressive.

8.c3 Bd6 9.d4 Bg4 


Black's Bishops balance White's central pawns - but they look scarier.

10.Qd3 h4 11.f4 

Bravely, if foolishly, ignoring the enemy h-pawn. Probably 11.h3 Bh5 12.f4 with an even position was the proper course. 

11...Qd7 

Stockfish 16 still gives Black the advantage after 11...h3 12. g3 c5 13.Be3 Qd7 

12.h3 

Correcting the oversight.

12...Bh5 13.e5 Be7 14.f5 Nh6 


This is still an interesting position (the computer suggests 15.e6 Qd8 16.Bf4 and that Black fight back with 16...c5 17.d5 c4 18.Qxc4 c6 19.d6 Bxd7 20.Bxd6+ Qxd6 21.Qxh4 and a small edge for White - choosing his 3 extra pawns over Black's extra piece ) and I am not sure why I offered a draw here.

Perhaps I was thinking of another game?

Jerome Gambit: Overlook One Small Thing...


In sharp, tactical positions it can be deadly to overlook something.

 The following game is a good example.


Wall, Bill - Gordy

internet, 2023

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.Qf5+ Kd6 8.f4 Qf6 9.Qxe5+ Qxe5 10.Qf3 Nf6 

11.Nc3 

Or 11.d3 Kc6 12.c3 Re8 13.b4 Bb6 as in Wall,B - Stoker,B, standard, FICS, 2020 (0-1, 28). 

11...c6 12.d3 

Sharper is 12.d4!?

12...Ke7 13.Bf4 Qe6 14.O-O-O h6 


15.d4 Bb4 16.d5 Qg4 17.e5 Bxc3


Exchanging on c3 and then on f3 would yield a balanced position.

Black overlooks something in allowing his other Knight to be captured, however.

18.exf6+ Black resigned

White removes the defender of Black's Queen, with check.

Jerome Gambit: Not So Boring



angelcamina - Davide313

1 0 bullet, lichess.org, 2023

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 

The boring Italian Four Knights Game.

5.Bxf7+ 

The not-so-boring Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bb4 8.dxe5 Bxc3+ 9.bxc3 Nxe4

This pawn-grab adds to Black's worries.

10.Qd5+ Ke7 11.Qxe4 Rf8 

Black has a plan to deal with the Bishop check along the dark diagonal, but it is inadequate. To be fair, at this point he is probably lost, anyhow.

12.Bg5+ Rf6 

Fair enough, but White has a forced checkmate.

13.exf6+ Kf7 14.Qd5+ Kf8 15.fxg7+ Kxg7 16.Bxd8 Black resigned


Black has lost his Queen.

White has a mate in 7.

Was H. Nakamura Right? Is JG ‘Unbreakable’, Is EG ‘Legendary’ For Beginners’ Games? (Part 2)

 



Was H. Nakamura Right? Is JG ‘Unbreakable, Is EG ‘Legendary’  

For Beginners’ Games? (Part 2)   

  

(by Yury V. Bukayev) 

 

 

If an expert’s appraisal is based on something without real proofs, he can be right or “almost right” here sometimes. That is so, even in the case where he realizes that his appraisal is hasty, or non-serious, or bold, or emotional. Sometimes he is right here for a large per cent (for example, 55, 75 or 95) of cases which he appraises. 

 

We remember Rick Kennedy’s post ‘Jerome Gambit: Which Tier? Unbreakable?’ (September 23, 2020) where the notable dialogue about the standard system of the Jerome gambit (JG) between Top GM Hikaru Nakamura and IM Levy Rozman was shown as the part of their popular video and as its approximate text. Thus, they have discussed there what chess opening tier for beginners practice is right for it. The end of this text contains several phrases by Mr. Nakamura where he places the standard system of JG near the top of ‘Unbreakable’. Mr. Nakamura’s words contain no proofs of this very high appraisal. In my opinion, the tier’s name ‘Unbreakable’ is very arguable, because we discuss an opening practice, not an opening theory: each opening can be broken in a game as a result of practical mistakes of a player. But this name plays no role for us, just this very high appraisal of 4.Bxf7+ for beginners’ practice is important for our consideration.  

  

Before writing of my Part 1 of this analytical research (please, look at it: it’s a blog post of October 16, 2022) it was enough difficult for me to prove this Hikaru Nakamura’s appraisal, for a large per cent of cases. It was necessary to choose a certain control of time for beginners games, and I have chosen an unlimited one. And in the Part 1 I have made one clear proof of this Mr. Nakamura’s appraisal and some “not absolutely clear proofs” of it.  

 

I think, my clear proof – my Trap 1 (the First Golden Beginner’s Trap’) for the standard system of JGwasn’t known to Mr. Nakamura then. Was some other clear proof known to him then? I don’t know, but I’m sure that the other variation was familiar to him then: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4!?. If White offers a draw this moment then, I think, a large part of opponents-beginners will accept it, because they don’t know opening theory and are afraid of such “very sharp” unknown positions with checks and different “long” attacks. And the word ‘unbreakable’ includes a draw, not only a win. It is my first idea.  

 

Even if Black chooses 7…Nf7 to have a calm King’s retreat back and to avoid checks then after 8.Qxc5! d6! White plays 9.Qc4+! AN Ke7! 10.b3, or 10.Nc3, or 10.0-0 with a long and a strong pressure and attack in both cases. It is mortal for a beginner as Black very often, although Black isn’t worse here. It is also my idea, but Mr. Nakamura could know and understand these facts before me (?), it is possible. 

 

And here is my new invented trap - no.4 - which is based on this variation, on its natural sub-variation. 

 

Trap 4. 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 (Black defends his pieces, it is a typical response for an unlimited game.) 7.f4 d6 8.fxe5 dxe5 9.b4 Qd4? AN (This mistaken blow is ‘natural’ for a beginner: he thinks about his attack, about maximum increase of his material advantage, not about opponent’s counter-attack. Moreover, beginners can’t count long variations. Black sees that after 9…Bf2+!? AN White can play 10.Ke2!?, and it is difficult to capture something for Black.) 10.bxc5 (It is a continuation of the trap. The alternative way 10.Qg4+ Kf7 11.Qf3+ Nf6 12.c3 is stronger for White, but Black controls his some advantage after his easy move 12…Qxe4+.) 10…Qxa1? (This mistaken capture is ‘natural’ for a beginner and is a continuation of his mistaken plan to get a maximum material advantage.) 11.Qe8+! Kf6?? (It’s a typical reaction for the beginner who has tried to get a maximum material advantage by his 9th and 10th moves and tries to save it. Alternatively, some beginners will start to think about possible checkmate, so they will play 11…Ne7!, but after 12.Qxh8 Qxb1! 13.0-0 White gets a very strong attack: 13…Qxc2! 14.d3 Qxc5+! 15.Kh1. Black has an extra Knight and an extra pawn, but White gets a draw as minimum, so this trap is unbreakable.) 12.0-0+ (12.Rf1+!? is also good.) 12…Kg5 13.d4+ Kh4 (13…Kg4 14.h3+ etc.) 14.g3+ Kg4 15.h3+, and White checkmates very rapidly.  

 

That is why White will get a very large per cent of identical wins and draws against surprised beginners after 7.f4!?.  

 

It maybe, the invention of my Trap 1, my Trap 4 and these my approaches will cause Mr. Nakamura’s and Mr. Rozman’s wish to replace the standard system of JG into their top tier ‘Legendary (on ‘GMHikaru’ YouTube channel). In any case, I suggest to name the Trap 4 as the ‘Second Golden Beginner’s Trap’.
