Was H.Nakamura Right? Is JG ‘Unbreakable’, Is EG ‘Legendary’ For Beginners’ Games? (Part 11)



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

For Beginners’ Games? (Part 11)

(by Yury V. Bukayev)

Again and again, 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, Part 2, Part 3 of this research I have made some clear proofs of this Mr. Nakamura’s appraisal and some “not absolutely clear proofs” of it. We shouldn’t forget that the word ‘unbreakable’ includes a draw, not only a win.

And here is my new invented trap - no.17 - which is based on a similar ‘natural’ reaction of a beginner.

Trap 17. 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.d4 Bb4+ 7.c3 Qh4 (It’s a strong theoretical way for Black, so White’s future trap is not only for games against beginners.) 8.dxe5!? Qxe4+ 9.Be3!? Qxg2 10.Rf1 Ba5? (It’s a typical reaction for beginners and not only for them: Black wants to not retreat from the centre, to continue …Bb6, to attack White’s important points. And it’s an idea of this trap.) 11.Qh5+! AN (White’s extremely strong idea 12.e6! makes the position unclear, with good chances for White to get an advantage further.)

That is why White will get here also a very large per cent of identical successful results against beginners. And against much more strong players!

It maybe, the invention of my traps 1, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 and my approaches (Part 1, Part 2) 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).

Jerome Gambit: Psychic Pain

I always experience a bit of psychic pain when I face the Jerome Gambit, instead of play it.

Worse yet, I have a slightly better score defending, compared to attacking.

So when I was recently challenged...


NN - perrypawnpusher

chess.com, 2026

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Qe7

As I noted in "Flaws (Part II)", concerning Blackburne's 7...d6

...Black has a stronger counter-attack here, starting with 7...Qe7! as Jerome discovered to his dismay in the games of his correspondence match with Lt. G. N. Whistler, secretary of the Lexington, Kentucky Chess Club, in 1876.

My advice, here, was clear in my post"Jerome Gambit: Don't Take the Rook" - mind you, in 7 games with the Black pieces in this position, I scored 100% when my opponent did take the Rook.

8.Qxh8 

For 8.Qd5+!?, see Yury V. Bukayev's "Anatoly Karpov & Jerome Gambit (Parts 7 & 8)" and "JG: The New in Its Opening Theory, in Its Psychology (Parts 15 & 16)",   

8...Qxe4+ 9.Kf1 Qh4 10.g3 Qh3+ 11.Kg1 

White is up the exchange and a pawn, but his King is in dire straits.

If 11.Ke1 Nf6 12.d3 Qg2 13.Rf1 d5 14.Qd8 (14.Bg5 Qxf1+ 15.Kxf1 Bh3+ 16.Kg1 Rxh8 17.Nd2 Ng4 18.Be3 Nxe3 19.fxe3 Bxe3+ White resigned, wolfwerner - perrypawnpusher, Jerome Gambit Classic #1, 2024) 14...Qxf1+ White resigned, Seishiro_Chess - perrypawnpusher, Jerome Gambit Classic #1, 2024

11...b6 

More to the point than 11...Qe6 12.Kg2 (12.d4, 12.Qxh7+) Qe4+ 13.Kg1 Qe1+ 14.Kg2 Qxf2+ 15.Kh3 d5+ 16.g4 Qf3+ 17.Kh4 Qxg4 checkmate, IndeedPerhapsYes - perrypawnpusher, Chess.com, 2021 

12.Qc3

With a defensive idea, but now Black has a forced checkmate. 

12...Bb7 13.Qc4+ Kg7 14.Qf1 

14...Qg4 15.h4  Qxg3+ 16.Qg2 Qxg2 checkmate



Pass the acetaminophen...

Jerome Gambit: Valuable Time (Part 6)

                                      

[continued from previous post]


perrypawnpusher - JAMARTINO

Not only the Italians play the Italian, Chess.com, 2025

The advanced pawn will distract a defender.

35...Rf8 36.Rxg6+ Kf5 

This careless move costs a piece. The King needed to continue to advance, instead, with 36...Kh3.

37.Rf6+ Kg4 38.Rxf1 Kh3 39.Bg7 Ra8 40.f8/Q Rxf8 41.Bxf8

Jerome Gambit: Valuable Time (Part 5)

                                         

[continued from previous post]


perrypawnpusher - JAMARTINO

Not only the Italians play the Italian, Chess.com, 2025

20...cxd4

Instead, 20...Be6 would advance Black's development, and protect his Rook at e8, e.g. 21.Rd6 b6, with the first player still a little bit better.

21.Qxe8+ Kh7 

Would exchanging Queens, instead, with 21...Qf8 22.Qxf8+ Kxf8 23.Rxd4 be more helpful for the defender? In the computer's post mortem, it was something to consider. 

22.Rxd4 b6 

A slip.

My opponent misses it.

I miss it.

23.Qxe4 

Readers, no doubt, can find 23.Rd8!? (pin and attack) Be6 24.Qh8+ Kg6 25.Rxa8 Qf7 26.Qe8 Qxe8 27.Rxe8 Bxa2 28. Ra8 Bb1 29. Rxa7 Bxc2 30. Bxb6 and things are largely resolved, as White is a Rook ahead.

23...Qxe4 24.Rxe4 Bf5 25.Re7 Bxc2 


With Rooks off the board, the position would be quite drawish, due to the Bishops-of-opposite-colors.

26.Bd4 Rg8 27.Rxa7 b5 28.Rb7 Bd3 29.Kf2 h5 

To limit the Kingside pawns, and, possibly exchange some: When ahead, exchange pieces; when behind, exchange pawns

30.Ke3 Bf1 31.g3 Kh6 32.Rb6+ g6 33.f5 

Building pressure against the enemy King.

33...Kg5 34.f6 Kg4 35.f7 


The f-pawn continues forward, disrupting the defense, in its own way.

Jerome Gambit: Valuable Time (Part 4)

                                       

[continued from previous post]


perrypawnpusher - JAMARTINO

Not only the Italians play the Italian, Chess.com, 2025

12...Nb4 

Harassing the Queen is often too tempting.

Tucking away the King with 12...Kg8 is more frequent in my games

perrypawnpusher - anomis, blitz, FICS, 2010 (1-0, 59);

perrypawnpusher - mjmonday, blitz, FICS, 2010 (1-0, 32);

perrypawnpusher - Angstrem, blitz, FICS, 2010 (0-1, 35); 

perrypawnpusher - Padalino, blitz, FICS 2010 (1-0, 20);

perrypawnpusher - amirelattar, blitz, FICS, 2010 (1-0, 50);

perrypawnpusher - yuriko, blitz, FICS, 2010 (1-0, 31);

perrypawnpusher - kholthaus, blitz, FICS, 2010 (0-1, 45); 

perrypawnpusher - DeDaapse, blitz, FICS, 2010 (0-1, 24); 

perrypawnpusher - JohnBr, blitz, FICS, 2010 (0-1, 31);

perrypawnpusher - tharadili, blitz, FICS, 2011 (1-0, 30); 

perrypawnpusher - kholthaus, blitz, FICS, 2011 (1-0, 17); 

perrypawnpusher - yuriko, blitz. FICS, 2011 (1/2 - 1/2, 37)

Also 12...Qe7 as in perrypawnpusher - alsuarezdi, blitz, FICS, 2010 (1/2 - 1/2, 88) 

13.Qc4+ d5 

With more time to think, my opponent finds the right response to the check: not 13...Kf8 as in perrypawnpusher - yuriko, blitz, FICS, 2011 (1-0, 34) or 13...Be6 as in  perrypawnpusher - grunf, blitz, FICS, 2010 (1/2 - 1/2, 69). 

14.Qxb4 dxe4 


Material is now even. It is not yet clear if the passed pawn on e4 is a strength or a weakness. White's King is safer.

15.Be3 

Blockade.

15...Nd5 

After the game, Stockfish 17.1 recommended this line of play: 15...a5 16.Qb5 Qe7 17.h3 c6 18.Qb6 Ra6 19.Qd4 b5 20.Rfe1 Ra8 21.a3 Kg8 22.Qb6 Ra6 23.Qc5 Qxc5 24.Bxc5 e3 25.Rxe3 Rxe3 26.Bxe3 Bf5 27.Rc1 h5 28.Bd4 Ra8 29.Nd1 Rd8 30.Bb6 Rd2 31.Bxa5 with an edge to White.

Wow. All those Queen moves for White, all those pawn moves for Black... It is clear that I am not a computer

16.Nxd5 Qxd5 17.Rfd1 Qf5 


Compared to the previous diagram, the Knights are gone.

Might as well continue to pressure the advanced e-pawn.

18.Rd4 Kg8 19.Rad1 c5 20.Qb5 


Both Kings are safe. White has the better development. Black has the passed pawn. 

Exchanging Rooks looks like a short-term plan.

Jerome Gambit: Valuable Time (Part 3)

                                              

[continued from previous post]


perrypawnpusher - JAMARTINO

Not only the Italians play the Italian, Chess.com, 2025

9...d6 


I have also faced

9...Nc6 

perrypawnpusher - mjmonday, blitz, FICS, 2010 (0-1, 26);

perrypawnpusher - DeDaapse, blitz, FICS, 2010 (0-1, 19);

perrypawnpusher - kinghh, blitz, FICS, 2010 (1-0, 31);

perrypawnpusher - transilvania, blitz, FICS, 2011 (1-0, 12);

perrypawnpusher - LeChinois, blitz, FICS, 2011 (1-0, 15);

perrypawnpusher - javipangea, blitz, FICS, 2011 (1-0, 19); 

perrypawnpusher - MrMef, blitz, FICS, 2012 (1-0, 27) 

9...Re8 

perrypawnpusher - Odeon, blitz, FICS, 2012 (1-0, 15) 

9...Qe7 

perrypawnpusher - philippemuurmans, blitz, FICS 2010 (1-0, 28);

perrypawnpusher - jaymen, blitz, FICS, 2010 (1-0, 40); 

perrypawnpusher - louarn, blitz, FICS, 2010 (1-0, 21);

perrypawnpusher - cinamon, blitz, FICS, 2011 (1-0, 25) 

10.f4 Nc6 

Although Stockfish 16.1 assesses (34 ply) this position as being 2 1/2 pawns better for Black, I have scored 12 - 4 - 3 (71%) in games with White in this position. 

There are 62 games in The Database with this position, and White has scored 73%.

Blame it on the Jerome Gambit.

Also seen is 10...c5 in perrypawnpusher - Leoleon, blitz, FICS, 2017 (1-0, 17)

11.Qd3 Re8 

Also 

11...Nb4 as in perrypawnpusher - havasiviktor, blitz, FICS, 2019 (1-0, 19); 

11...g6 as in perrypawnpusher - gmann, blitz, FICS, 2011 (1-0, 36); 

11...Rf8 as in perrypawnpusher - pwr, blitz, FICS, 2010 (1-0, 38) and perrypawnpusher - HRoark, blitz, FICS, 2011 (1-0, 21); 

11...Be6 as in perrypawnpusher - HRoark, blitz, FICS, 2010 (0-1, 40) 

12.Bd2 

White is getting to swing his Queenside Rook to e1 and put more pressure on the enemy King. Sounds simple.

Didn't happen.
