Was H.Nakamura Right? Is JG ‘Unbreakable’, Is EG ‘Legendary’ For Beginners’ Games? (Part 8)

 


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

For Beginners’ Games? (Part 8)

(by Yury V. Bukayev)


Dear readers, again I repeat the following. 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 1Part 2Part 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.13 - which is based on a similar ‘natural’ reaction of a beginner. 

 

Trap 131.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.Qf5+ Kd6 8.d4 Bxd4 9.Bf4 AN (It’s the 1st part of my new and primitive trap against beginners.) 9…Bxb2 (It’s a typical and a nice reaction for everyone. Black has a winning advantage.10.c3 (It’s the 2nd part of this trap against beginners. They desire to make 10…Bxa1, and they start to celebrate their future win without thinking about plans of the silly unknown opponent.10…Bxa1?? 11.Qxe5+! White wins. The fastest way to win here after 11...Kc6 is 12.Na3! d5 13.exd5+ Kb6 14.0-0 with the following Rf1-b1.

 

That is why White will get here also a very large per cent of identical successful results against beginners (especially children-beginners).  


It maybe, the invention of my traps 1, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and my approaches (Part 1Part 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: "Too Creative"



The wrong defense to the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) makes White's attack look very good.

The following game is a fun example.


Tracy824 - Alex3959

5 0 blitz, lichess.org, 2025

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.f4 Ng6 

About this Knight retreat in "Jerome Gambit: Pillar to Post"

Some reflections -

from "Superpippo!"

This move, despite the soundness of the basic idea – save one piece and return another – is too "creative" and leads to an even game. With a regular opening, having Black reach equality this early is an accomplishment for the second player, but in the Jerome Gambit – where White spots his opponent two pieces – it is a sign that something has already gone wrong for Black. 

The kind of move - withdrawing a piece from attack - that someone unfamiliar with the Jerome Gambit might make quickly. (Best was 7...Qf6). 
My guess is that at this point Bill [Wall,B - Guest1157782, playchess.com, 2013 (1-0, 20)got out his psychic micrometer, measured the apparent depth of his opponent's experience with (or understanding of) the opening, and chose a line of play that was most efficacious against an unschooled or uneasy opponent. 
With more time to consider - the whole point of playing the Jerome Gambit... is that Black does not have much time to consider - Black would have found the less sensible (but stronger) 7...d67...Nd37...Qf6 or 7...d5.

8.f5+ 

This move appears in 55 games in The Database. White scores 69%.

The alternative, 8.Qxc5, appears in 54 games. White scores 79%. 

Stockfish 16.1 asseses Black about 1 1/4 pawns better in the first case, and about even in the second.

8...Kd6


Tracy824 has also faced

8...Kf6 9.fxg6 Nh6 10.Qxc5 hxg6 11.O-O+ Ke6 12.Qd5+ Ke7 13.Qe5 checkmate, Tracy824 - muchtarpcw, lichess.org, 2025; and

9.fxg6 Bd4 

Black's move is unexpected - reinforcing the Kingside side of the a1-h8 diagonal? 

Tracy824 also faced 9...Qf6 10.Qd5+ Ke7 11.Qxc5+ d6 12.Qf2 Qxf2+ 13.Kxf2 hxg6 14.d3 Nf6 15.Bg5 b6 16.Nc3 Bb7 17.h3 Rhf8 18.Ke3 Kd7 19.Rhf1 Nh7 20.a4 Rxf1 21.Rxf1 Nxg5 22.h4 Ne6 23.d4 Rf8 24.Re1 g5 25.d5 Nf4 26.Kd2 Nxg2 27.Rg1 Nxh4 28.Rxg5 Nf3+ 29.Ke3 Nxg5 White resigned, Tracy824 - Tom0408, lichess.org, 2025 

Probably best was 9...Nf6.

10.Qd5+ Black resigned

Jerome Gambit: Creative and Cool, Again


The lichess.org player rincincinzio has 400 games in The Database. 

Here is one of them.


rincincinzio - jayamie

1 0 bullet, lichess.org, 2025

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.f4 Nd3+ 

I like, play, and score well with the Jerome Gambit - 82%.

Still, I like this move. Black must have played it with a smile on his face.

This has been touched upon in an earlier post, "Jerome Gambit: For You or Against You"

I have posted earlier

I like this quirky move. Stockfish 15 does, too, seeing Black as almost 4 pawns better. Still, The Database has 25 games with this move, with White scoring 64%.

As I wrote in "Jerome Gambit: It Takes More Than A Move"

Creative and cool.

Anyone who has read Aron Nimzowitsch's The Blockade will recognize the idea behind this move.

Something similar is equally deadly for Black, when the d-pawn is blocked, which in turn blocks the Bishop, which then keeps the Rook from entering the game. 

I have looked at this move before, in "Brilliant, but Not Sound" and "Jerome Gambit: The Hurrieder I Go, The Behinder I Get", where you will see Petasluk mentioned as well.

The numbers, today, from The Database: 73 games with this position, White scores 64% - despite the fact that Stockfish 16.1 evaluates the position (32 ply) as 2 3/4 pawns better - for Black.

Jerome Gambit. 

8.cxd3 Be7 

What to do about the Bishop? It could have retreated to b6, or even f8. Or Black could have hit the center (best) with 8...d5

Instead, it blocks the King's retreat.

In a 1-minute bullet game, this kind of thing can happen.

9.Qf5+ Kd6 10.Qd5 checkmate

Jerome Gambit: Remarkably Effective

An "objective" assessment of the Jerome Gambit is that Black should win.

A practical assessment of the Jerome Gambit played at the club level, however, is that it can be remarkably effective for White.

The successful path of the first player, it must be admitted, involves passing through initial dangers. 

In the following game, Bill Wall is accompanied in his journey by four passed pawns, and they chaperone him successfully. 


Wall, Bill - Twister

internet, 2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qxc5 d6 8.Qd5+ Ke8 9.O-O 

Black has the typical Jerome Gambit piece-for-two pawns advantage.

White's castling makes sense, before he is distracted by threats to his Queen.

Bill has also played 9.d3 c6 10.Qb3 as in Wall,B - Seven11, Chess.com, 2008 (1-0, 51); and 

9.d4 N8e7 10.Qb3 as in Wall,B - Am53, PlayChess.com 2013 (1-0, 14) and Wall,B - Guest7665109, PlayChess.com, 2019 (1-0, 22).

9...Nf4 10.Qb5+ 

Bill has raised this question in similar positions in other games - Block the check with the Bishop and lose the b-pawn? He now suggests 10.Qa5

10...c6 11.Qc4


A slip, unusual for Bill, as Black now has the murderous 11...Be6. Instead, the second player plays an even more dangerous move.

11...Qg5 12.g3 Bh3

This move is okay, but 12...Qh5 (or 12...Be6) was stronger.

13.Re1 Qg4 14.e5 


Opening the e-file against the enemy King bids to keep White in the game.

The Queens can now come off the board with 14...Qf3 15.Qe4 Qxe4 16.Rxe4 Ng6 17.exd6+ Kd7 and both Kings looks safe. 

14...d5 15.Qxf4 Qxf4 16.gxf4 

Stockfish 16.1 evaluates White as being about a pawn better, but that extra one is passed and protected.

Now White's Rook becomes active and infiltrates the enemy position.

16...Nh6 17.Re3 Bf5 18.d3 Ng4 19.Rg3 h5 20.f3 Nh6 21.Rxg7 Kf8 22.Rxb7 

22...Rg8+ 23.Kf2 Rg6 24.Nc3 d4 25.Ne4 Bxe4 26.dxe4 h4 


White's "Jerome pawns" are scary.

27.f5 Nxf5 28.exf5 Rg8 29.Bh6+ Black resigned

White has a checkmate in 7.
