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

For Beginners’ Games? (Part 6)

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 are my new invented traps - no.9 and no.10 - which are based on a similar ‘natural’ reaction of a beginner.

Traps 9 and 10. 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.Qf5+ Kd6 8.f4 Qf6 9.fxe5 Qxe5 10.Qf3 Nf6 11.b4! Qxa1!? (It’s a typical reaction for beginners and not only for them. Moreover, 11…Qxa1 isn’t a bad move here, so it is a true opening variation, in fact.) 12.bxc5+! Ke7 13.0-0! Qxb1?! (It’s also a typical reaction for beginners and not only for them, so 13.0-0 is my trap no.9.) 14.e5! Ne8? (It’s again a typical reaction, so 14.e5 is my trap no.10.) 15.Qf7+! (White has a large advantage, although it is not easy to see yet.) 15...Kd8 16.d4 h6 17.Bg5+ hxg5 18.Rxb1. White wins. Black can play 16...Nf6 instead, but it doesn't save too. The whole variation 11.b4 contains my traps no.7-10, and all of these four White's moves are strong.

That is why White will get here also an extremely 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 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: Worry Begats Distraction?

If I were to guess about the following game, I would say that Black was surprised that a move that he had prepared against, was, nonetheless played against him; and this had an adverse effect on his following move, and, thus, the game.

Bill Wall shows himself to be a bit of a practical psychologist with his play.

Wall, Bill - Bose

SparkChess, 2025

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 

There are almost 4,400 games with this position in The Database, going back to Jerome - Norton, correspondence, 1876 (unfinished).

6...d6 

By contrast, this practical way of dealing with the pawn attack on two pieces - let White decide which one he wants, Black will save the other - appears in only 108 games in The Database, with the earliest being in 2003.

7.dxc5 Bg4

More frequently seen is 7...Nf6, which Bill has scored 6 - 1 - 1 against. 

The idea behind the text can be seen if White reacts by blocking the Bishop with 8.f3, because 8...Qh4+ would then displace the King, leaving it unable to castle.

However, Bill has something other in mind.

8.Qd5+ 

This Queen check raises the same question that we have seen when Black's light-squared Bishop is at home - Is the response ...Be6, giving up the b-pawn, a good idea? Should the developed Bishop be called back?

8...Ke7 

Instead, 8...Be6 9.Qxb7 was seen in Wall,B - Guest8860423, PlayChess.com 2019 (1-0, 46). Stockfish 16.1 prefers the block by the Bishop. 

Bill has also faced 8...Ke8 in Wall,B - MLVD, internet, 2021 (1-0, 14).

9.Qxb7 Nf6 10.Nc3 dxc5 

This is an interesting position. White has two pawns for his sacrificed piece. His Queen risks being out of play. Black's King is not safe.

The computer sees the position as equal. I suspect that most Jerome Gambit players would prefer playing White.

11.Bg5 Rf8

Reinforcing the Knight.

I think Black would have been happy with his piece play after 11...Rb8 12.Qxa7 Qd6 13.f3 Be6 14.Rd1 Qc6.

12.Nd5+ 

Anyway.

12...Ke8

Black decides to let his Queen protect the Knight, and retires his King (to an unfortunate square). Instead, he could have held on to his slight advantage with 12...Kf7.

The text move drops a Rook.

13.Nxc7+ Kf7 14.Nxa8+ Bd7 

White's 14th move comes with check, thanks to where Black's King placement.

15.Nc7 

15...h6 16.Bxf6 Qxf6 17.Qd5+ Kg6 18.O-O-O 

White is the exchange and three pawns ahead.

Black's compensation is minimal.

18...Rc8 19.Qxc5 Be6 20.Rd6 Nd7 21.Qa5 Black resigned

Black's Bishop is at risk, and exchanging it off - with 21...Qf4+ 22.Qd2 Qxd2+ 23.Kxd2 Rxc7 22.Rxe6+ - or protecting it - with 21...Nf8 22.Nxe6 Nxe6 23.Qd5 Kf7 - leaves his game with poor prospects.

                             JG (4.Bxf7+) against Maestri: 

                           the Collection of Practice (Part 3)

                                                by Yury V. Bukayev

Dear readers, let me remind you that these my new posts about White's advantage and wins in such chess games are dedicated to the 150th anniversary of Alonzo Wheeler Jerome's publications with 4.Bxf7+ in Giuoco Piano. Now the world chess history knows a lot of cases, where White got an advantage or won here against grandmasters and other extremely strong defenders!

We should start this new part from the game

Kevin Sheldrick - GM Martin Kraemer 

("Cliff Hardy" - DrawDenied_Twitch, 10 min tempo, lichess.org, 2023, https://jeromegambit.blogspot.com/2023/02/jerome-gambit-return-of-cliff-hardy_0627317739.html ),

where for 4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Qf6 9.fxe5+ Qxe5 10.Qf3 Nf6 11.d3 Ke7 12.Nc3 d6 13.Bf4 Qh5 Black spent too much time for these known opening moves. White has commented here: "The GM spent 2 minutes and 37 seconds on that move. With the remaining clock times now down to 5:39 (me) and 1:38 (him), I clearly had a big time advantage". I thank Mr. Sheldrick. It maybe, Mr. Kraemer calculated my invented way here so long time: 14.Nd5+ Kd8 15.Qxh5 Nxh5 16.Bg5+ Kd7 17.g4 h6 18.Bd2 Nf6 19.Nxf6+ (or 19.Bc3 Nxg4!? 20.Rf1!, that is stronger than 20.Bxg7 Rh7 21.Nf6+) 19...gxf6 20.Bc3 Ke7 21.Rf1 Rf8 22.d4 Bb6 23.Rf4, but 10 min time control punishes you, when you play so slowly. And I think, White also could play quicker before 13.Bf4, so his time advantage could be bigger. Further, first of all, I agree, that after

14.Nd5+ Kd8 15.Qxh5 Nxh5 16.Bg5+ Kd7 17.g4 h6 18.Bh4 g5 19.gxh5 gxh4 20.c3 c6 21.Nf4 Be3 22.Ng6 Re8 23.Ke2 Bg5 24.Raf1 Kc7 25.Rf7+ Kb6 

White should play 26.Rg1!, and White could win on time here with a solid position. After 26.Rhf1? Bg4+ we have a pure endgame, where Black's task has become much easier. Nevertheless, the extreme lack of time caused Black's Bishop blunder (35...Kb5), and White could get the drawn position by 36.Rf5+ Kb6 37.Rxh5 and win on time easily.

Further, we'll remind the game 

NN - Top GM Hikaru Nakamura (GM_xAhmedx - GMHikaruOnTwitch, 3 min blitz, Chess.com, 2021), 

where after  4...Kxf7 5.Nxe5+Nxe5 6.O-O Be7 7.d4 Ng6 8.Qf3+ Ke8 9.Nc3 d6 10.Re1 Nf6 11.e5 dxe5 12.dxe5 Ng4 13.Rd1 N4xe5 14.Rxd8+ White became a large advantage. White's mistake 6.0-0? was met by enough passive response 6...Be7. Black's play was not active, after some moves Black blundered, as we see here. It maybe, Mr. Nakamura was tired during this his Jerome Gambit Arena, but we can see an interesting fact: after 6.0-0? Black started to play not attentively: he solved that White must lose in any case! And it is a typical psychological trap for Black in Jerome gambit games after 4.Bxf7+.

That is so, even in the case where he realizes that his appraisal is hasty, or non-serious, or bold, or emotional.

And here are my new invented traps - no.7 and no.8 - which are based on a similar ‘natural’ reaction of a beginner.

Traps 7 and 8. 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.Qf5+ Kd6 8.f4 Qf6 9.fxe5 Qxe5 10.Qf3 Nf6 11.b4! AN (The analogous idea after 8…Qh4+ 9.g3 Qf6 10.fxe5 Qxe5 11.Qf3 Nf6 is 12.b4 AN with a similar play, but we have no opportunity to consider it now.) 11…Qxa1!? (It’s a typical reaction for beginners and not only for them. Moreover, 11…Qxa1 isn’t a bad move here, so it is a whole opening variation, in fact. Nevertheless, 11.b4 is my trap no.7, because after another “natural” response-mistake 11…Nxe4? 12.bxc5+ Nxc5+ 13.Kd1!! Qxa1!? 14.Nc3 the position is unclear.) 12.bxc5+! Kxc5? (It’s also a typical reaction for beginners and not only for them. This “natural” move is a blunder, in fact. So, 12.bxc5+ is my trap no.8. This is a rare case in Jerome gambit: both traps on the same opening line are strong moves.) 13.d4+!!, and White has a large advantage.

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 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: Is A Draw Good Enough?

One timeless question when it comes to the Jerome Gambit has been whether a draw is a good enough result for White, after his wild sacrifices.

In the following game, Bill Wall declines an offer to split the point, and receives his opponent's resignation a couple of moves later.

Wall, Bill - Braveheart

SparkChess, 2025

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Kf8 

Black's King simply steps away from the action. 

The Database has 10 games with this position. White scores 60%.

7.dxc5 Nf6 8.O-O d6 9.Nc3 Be6 10.f4 

Black has the piece development, White has the center pawns.

10...Nc6 11.Be3 Qe7 12.cxd6 Qxd6 

Capturing with the pawn was probably better.

13.Qf3 Nd4 14.Qd1 Nc6 15.Qe2 

Declining to go for the draw with 15.Qf3 Nd4 16.Qd1 etc. 

The game is now about balanced.

15...a6 

This may have been intended to keep a Knight off of b5.

More aggressive was 15...Qb4, which could lead to the win of the exchange, 16.e5 Bc4 17.Qf3 Bxf1 18.Rxf1 Nd7, although after 19.Nd5 Stockfish 16.1 continues 19...Qc4 20.b3 Qxc2 21.Nxc7 Re8 22.Qd5 Re7 23.Ne6+ Ke8 24.Nc7+ Kd8 25.Nb5 Qe2 26.Bc5 Rhe8 27.a4 Rxe5 28.fxe5 Qxe5 29.Qxe5 Rxe5 30.Bd6 Re2 31.Bg3 Nde5 32.Rd1+ with an equal game.

16.e5 Qb4 

This is a move too late.

17.exf6 Bc4 

Again, too late.

18.Qh5 Bxf1 19.Bc5+ Black resigned

Black will lose his Queen.

Jerome Gambit: Even A Single Trap?

Long ago - 16 1/2 years (see "Junk Openings"), National and FIDE Master Dennis Monokroussos, philosopher at Notre Dame University, pondered "Is there even a single trap for Black to fall into in the Jerome Gambit?"

Although a bit late, the following game is one answer.

Wall, Bill - Dasasary

SparkChess, 2025

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d6 8.O-O Nf6 

Seen as early as Jerome - Shinkman, Iowa, 1876 (1/2-1/2, 41 ).

9.f4 Nc6 10.Qd1 

Something new for Bill. Three times before, he has chosen 10.Qd3. 

10...Re8 11.Nc3 Kg8 12.f5

Setting a trap.

12...Nxe4 

Falling in. 

13.Nxe4 Rxe4 14.Qd5+

14...Re6 

A sad necessity. 

15.fxe6 Qe7 16.Bg5 Qxe6 

If he was going to capture the pawn, using the Bishop was better.

17.Rae1 

Offering his Queen.

17...Ne5 

Only the sad 17...Nd4 would hold off an upcoming checkmate.

18.Rxe5 Black resigned

Neither of White's major pieces can be captured, and checkmate is still on the horizon.

Q.E.D.

Jerome Gambit: No Gutter, This Time

There is an old chess caution against capturing the b-pawn, lest one wind up "sleeping in the gutter".

But that is not always true. In the following game, White is able to grab Queenside material and still safeguard his Queen.

Wall, Bill - Dalos

SparkChess, 2025

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4

Not everyone plays 6.Qh5+. It is good to vary. Besides, 6.d4 was Alonzo Wheeler's choice when he began playing the Jerome.

6...Bxd4 7.Qxd4 d6 8.Nc3 h6 

The computer says that Black can afford to play this move, but it can not be best.

9.Bf4 c5 10.Qd5+ 

We have seen this kind of Queen check before.

Will Black hold onto his b-pawn, or sacrifice it for tempo?

10...Be6 11.Qxb7+ Ne7 12.O-O-O 

White is making the best of his chances. Stockfish 16.1 now presents one move that allows Black to keep his advantage.

12...Rf8 

Not this one. 

Instead, 12...Rb8 13.Qa6 Rb6 14.Qxa7 Nc4 would allow Black to put too much pressure on the White King, e.g. 15.b3 Qc8!? 16.bxc4 Ra6 and White's Queen will be lost.

13.Bxe5 

Taking advantage of the unfortunate pin on the d-pawn.

13...Rb8 14.Qxa7 Kg8 

Finishing castling-by-hand.

He could have chased the enemy Queen with 14...Ra8 15.Qb7 Rb8 16.Qa6 Rb6 17.Qd3 but that would have amounted to little.

15.Bxd6 Rf7 16.Qxc5 Black resigned

After 16...Rc8 17.Bxe7 Qxe7 18.Qxe7 Rxe7 White would be ahead by 5 pawns.
