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’.

Jerome Gambit: Battle Joined



The "Play the Italian Game III" tournament at Chess.com, has finished. I finished in 4th place (out of 56), with 20 wins, 9 losses, and 5 draws.

Meanwhile, the "Giuoco Fun" tournament, also at Chess.com, has started, and for Round 1, Group 14 I have been successful playing the Jerome Gambit against m2mkiss (won), Steadfast61 (won), TorenKoning777 (won on time), and jackedU711 (drawn).

With a score of 7 1/2 out of 8 overall, that is enough to progress to the second round.

By the way: there are 250 players in the tournament!

Nobody expects the Jerome Gambit! (Part 5)

[This is the continuation of an article from the "Unorthodox Openings Newsletter" (UON-21, May - August 2008), mentioned in an earlier blog post.]




Does the Jerome Gambit still have more secrets to give up? Sure it does! My friend AB was inspired by my tales of this Jerome Gambit Tournament, and played some online games that touch on JG theory. I quickly gave him the nickname “the unluckiest Jerome Gambit player in the world.”

First, my chess friend fell into a previously unknown trap: 

abhailey - peonconorejas [internet 2008] 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Qh4+ 

Planning a remarkable Queen sacrifice. The move has been seen before, but not the follow-up. The line has a computer-like feel to it, but the game was played at a no-computer venue. 

9.g3 Nf3+ 10.Kd1 Ne7 11.e5+ Kc612.Qe4+ d5 13.exd6+ Nd5 14.gxh4 Bg4 15.Qa4+ b5 16.Qa6+ Nb6 17.c4 Nd4+ 18.Ke1 Rhe8+ 19.Kf2 Nf5+ 20.Kf1 Bh3# 

Not to lose hope, AB jumped back up and found another snare almost immediately: 

abhailey - cruciverbalist [internet 2008] 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Qe7

This is Whistler's Defense, not very well known at all, but in my opinion the sharpest way to counter the Jerome Gambit. If White now takes the Rook, he dies screaming… 

8.Qf4+ Nf6 

However, if you're going to play any refutation, you have to play it correctly. The proper move for Black is 8…Qf6! Now my pal gets out of trouble and then quickly outplays his opponent.

9.e5 Re8 10.d4 Bxd4 11.Qxd4 Qxe5+ 12.Qxe5 Rxe5+ 13.Be3 Nd5 14.0–0 Nxe3 15.fxe3+ Kg7 16.Nc3 a6 17.Rf3 b5 18.Raf1 Bb7 19.Rf7+ Kh6 20.Rxd7 Rxe3 21.Rxc7 Be4 22.Re7 Rd8 23.Rxe4 Rxe4 24.Nxe4 Rd4 25.Re1 a5 26.h3 a4 27.c3 Rd5 28.Rf1 Re5 29.Nd6 Re2 30.Rf2 Re1+ 31.Kh2 Re7 32.Nxb5 g5 33.c4 Kh5 34.c5 Re8 35.c6 Rc8 36.c7 h6 37.Rf7 Kg6 38.Rd7 Kh5 39.Rd8 Rxc7 40.Nxc7 Kh4 41.Rd6 g4 42.g3+ Kg5 43.h4+ Kf5 44.Rxh6 Ke5 45.Re6+ Kf5 46.h5 a3 47.bxa3 Kg5 48.h6 Kf5 49.h7 Kg5 50.h8Q Kf5 51.Qf6# 

As ever, I am always interested in any Jerome Gambit games you may find or play. Feel free to email them to me at richardfkennedy@hotmail.com.

Nobody expects the Jerome Gambit! (Part 4)

[This is the continuation of an article from the "Unorthodox Openings Newsletter" (UON-21, May - August 2008), mentioned in an earlier blog post.]




    7.Qxc5 

A bit more accurate might be 7.Qd5+ followed by 8.Qxc5, first forcing Black's King back and delaying the emergence of his King's Rook. This is a nuance, and nuances are hard to find in a Jerome Gambit Tournament!

By the way, with the text move White scored 6 wins and suffered 13 losses. 

    7…d6 

This was the most popular response, although one game saw 7…Ng8e7 and another 7…Qe7. In either case (Black won both games), White's plan should be to develop and get his pawns moving against Black's King.

Bullit52 - savage13

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qxc5 N8e7 8.0–0 Rf8 9.d3 Kg8 10.Bg5 d6 11.Qc4+ Kh8 12.Nc3 c6 13.Ne2 b5 14.Qc3 Be6 15.Nf4 Bg8 16.Nxg6+ hxg6 0–1 

    8.Qe3 

Queen checks from d5 (two wins for Black) or c4 (one win for White) were also played as was a retreat to c3 (two wins for Black and one win for White). In each case, the goal is the same: to make something out of White's 2 pawns vs Black's piece – before the Black King gets to safety.

Nestor250168 - NMTIGER

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qxc5 d6 8.Qc3 Nf6 9.d3 Re8 10.0–0 b6 11.Bg5 Ne5 12.f4 Neg4 13.h3 Ne3 14.Rf3 Nd1 15.Qb3+ Be6 16.c4 Nxb2 17.Qxb2 h6 18.Bxf6 Qxf6 19.e5 Qh4 20.Nd2 a5 21.f5 Bd7 22.e6+ Bxe6 23.fxe6+ Kxe6 24.Qxg7 Rg8 25.Qf7+ Ke5 26.Qd5# 

    8…Nf6 9.0-0 

Black's move is the most consistent – to focus an attack on the pawn at e4. White does best to move his King out of the line of fire. 

Bullit52 - SIRMO

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qxc5 d6 8.Qe3 Nf6 9.Nc3 Re8 10.0–0 d5 11.Nxd5 Nxd5 12.Qb3 Rxe4 0–1 

blackburne - savage13

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qxc5 d6 8.Qe3 Nf6 9.Nc3 Re8 10.d3 Kg8 11.0–0 Bd7 12.Qg3 a6 13.Bg5 Qc8 14.Bxf6 gxf6 15.Nd5 Kf7 16.f4 Bc6 17.Ne3 Rg8 18.f5 Ne5 19.Qh4 Rg7 20.Qh5+ Kg8 21.Rf4 Qd7 22.Rh4 Rg5 23.Qh6 Nf3+ 24.Kf2 Nxh4 25.Qxh4 d5 26.Ng4 Rg7?? 27.Nxf6+ Kh8 28.Nxd7 Bxd7 29.Qf6 dxe4 30.dxe4 Bc6 31.Kf3 Re8 32.Re1 Kg8 33.Qd4 Rf7 34.Kf4 h5 35.Re3 h4 36.g3 Rfe7 37.e5 h3 38.g4 Bg2 39.g5 1–0 

    9…Re8 10.f3 [Or 10.d3, with the same idea.] 10…d5 11.d3 

Black has defended well, and now White will need a little help from his friend to succeed – which in this case, he does. 

Nestor250168 - plummy

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qxc5 d6 8.Qe3 Nf6 9.0–0 Re8 10.f3 d5 11.d3 dxe4 12.dxe4 Bd7 13.Qb3+ Be6 14.Qxb7 Re7 15.Be3 h5 16.Nc3 a5 17.Bc5 Rb8 18.Bxe7 Nxe7 19.Qa6 Qd2 20.Rf2 Qe3 21.Qxa5 Rxb2 22.Nd1 Qd4 23.Nxb2 Qxb2 24.Rd1 Qxc2 25.Rxc2 1–0

There you have it: a modern look (and 156 games is a pretty big look [a game database was attached to the UON issue]) at an ancient gambit. I hope it brings you a few chuckles, either at or with the Jerome.

Rest assured, the editors at Gambit or Everyman Chess or Batsford will not come calling looking for a book from me on the Jerome Gambit. (However, some time this year – I still have hope – the German chess magazine Kaissiber may run a historical article based on my research. [This article never came to pass.])

Nobody Expects the Jerome Gambit (Part 3)

[This is the continuation of an article from the "Unorthodox Openings Newsletter" (UON-21, May - August 2008), mentioned in an earlier blog post.]



Three examples give some of what both White and Black are aiming for: 

karmmark - manago 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.d3 h6 6.0–0 Nf6 7.Nc3 Rf8 8.Nd5 Kg8 9.Nxf6+ Qxf6 10.a3 d6 11.Re1 Nd4 12.Nxd4 Qxf2+ 13.Kh1 Bxd4 14.c3 Bh3 15.g3 Qg2# 

savage13 - Ratscales 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.d3 h6 6.0–0 d6 7.Nc3 Qf6 8.Be3 Qg6 9.Bxc5 Bh3 10.Nh4 Qg5 11.Qf3+ Nf6 12.Qxh3 dxc5 13.Nf5 g6 14.Ne3 Ke8 15.Qe6+ Ne7 16.Ned5 Nfg8 17.Nxc7+ Kf8 18.Nxa8 h5 19.Nc7 h4 20.Ne2 h3 21.g3 Qd2 22.Rae1 Qg5 23.f4 exf4 24.Rxf4+ Nf6 25.Rxf6+ Kg7 26.Qxe7+ Kh6 27.Nf4 Rg8 28.Nce6 Qe5 29.Rxg6+ 1–0 

drewbear - savage13 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0–0 d6 6.d3 Nf6 7.Bg5 Rf8 8.Nc3 Be6 9.Nd5 Bxd5 10.exd5 Nd4 11.Nxd4 Bxd4 12.c3 Bb6 13.Qf3 Kg8 14.h4 Qd7 15.Bxf6 Rxf6 16.Qe2 Raf8 17.Kh1 Rxf2 18.Rxf2 Rxf2 19.Qe1 Qg4 20.d4 0–1 

    5…Nxe5 6.Qh5+ 

This is White's usual continuation of the attack, although in seven games of the Tournament 6.d4 (once a favorite of Alonzo Wheeler Jerome) was played, with White scoring 4-3. (The strongest response for Black is 6…Qh4! which players did not discover in the Tournament.) 

savage13 - karmmark

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.d4 Qf6 7.dxc5 Ne7 8.0–0 Re8 9.Nc3 Kg8 10.f4 Nc4 11.e5 Qf5 12.b3 Na5 13.Bb2 Nac6 14.Nd5 Nxd5 15.Qxd5+ Qf7 16.Qd3 Nb4 17.Qc3 a5 18.Rae1 Nd5 19.Qd4 c6 20.f5 Nb4 21.Qe4 Nd5 22.c4 Nc7 23.f6 g6 24.Bc1 Ne6 25.Bh6 Nc7 26.Bg7 Ne6 27.Bh6 Nc7 28.Rd1 Na6 29.Qd4 Nc7 30.Rd3 Ne6 31.Qe4 Nxc5 32.Qd4 Ne6 33.Qh4 g5 34.Bxg5 Nc5 35.Rg3 Rxe5 36.Bf4+ Kh8 37.Bxe5 Ne6 38.Rf5 d5 39.Rg7 Nxg7 40.fxg7+ 1–0 

    6…Ng6 

In 7 games Black played instead the adventurous 6…Ke6. Although objectively the move leads to an advantage for the second player, it is uncomfortable step for someone unfamiliar with the Jerome Gambit to play (and defend afterwards), so it is not surprising that in the Tournament that White scored 6-1. 

Also quite playable for Black is the alternative 6…g6, as Joseph Henry Blackburne played in his miniature against the Jerome Gambit in London in 1885. Knowing how to follow up the move – 7.Qxe5 Qe7! is important, however, or the impending “loss” (actually a strong sacrifice) of a Rook may cause Black to panic.
