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#
