Chess Opening Nomenclature (Part 1)

 


The Common Approaches To The Chess Opening Nomenclature  

Part 1: The Queen's Gambit, JG-Lines: The Nature, Names, The New View 

 

(by Yury V. Bukayev) 

 

 

It is known that the formation of the chess nomenclature (including names of chess openings) is a result of many historical causes. Thus, some names are strange (or even extremely strange), but the chess world will continue to use the majority of themalthough it is valuable to use new correct synonyms for them too. The ideal order in chess opening names has a value. Thus, someone can ask you following questions:  

 

1. Is the Queen’s Gambit (1.d4 d5 2.c4) true gambit?  

2. Is the ‘Jerome Double Gambit’ (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+) - we can see this name rarely - true double gambit 

3. If no (in both cases), then what name is the most suitable (for the chess world) for it (in both cases)? 

4. Does a true Queen’s Gambit exist?  

 

Let’s create right answers. The article ‘Queen’s gambit’ on en.wikipedia.org site has right words: “It is traditionally described as a gambit because White appears to sacrifice the c-pawn; however, this could be considered a misnomer as Black cannot retain the pawn But I disagree with the end of this sentence (“…without incurring a disadvantage.”), here is my variant of its right end: “…in result of White’s possible immediate attack to return a material. This end is based on the fact: 2.c4 dxc4 3.Qa4+ (for example) 3…Nc6 4.e3, and White grabs Black’s pawn on c4 so White returns a material. It plays no role who has a positional advantage here. So 2.c4 isn’t a true sacrifice, it’s a suggestion to exchange pawns on the square c4 really. So the ‘Queen’s Gambit’ (1.d4 d5 2.c4) isn’t a true gambit, it is a pseudogambit (‘Wikipedia’ is right). We call it a ‘gambit’ traditionally so this large tradition makes this incorrect name suitable, but the synonym - the ‘Queen’s Pseudogambit - is suitable for the chess world too.  

Analogously, after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ (it’s a true sacrifice, i.e. a true gambit – the Jerome Gambit) 4…Kxf7 the move 5.Nxe5+ isn’t a true sacrifice, it’s pseudogambit, so the ‘Jerome Double Gambit’ (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+) isn’t a true double gambit. It is based on the fact: 5.Nxe5+ Nxe5 6.d4 (or 6.Qh5+ Ke6 7.f4), and White can grab Black’s minor piece so White returns a material. There is no a large tradition to call it a ‘double gambit’ so it’s the most suitable for the chess world to call it a non-gambit (a pseudogambit) move of the Jerome Gambit 

Let’s look at the nomenclature of the King’s Gambit (as a famous true gambit) so we can see the exact word analogy for the Jerome Gambit that is the most suitable for the chess world: 

 

1.e4 e5 

King’s Gambit (2.f4) → King’s Gambit Accepted (KGA, 2.f4 exf4 

→ Bishop’s Gambit (2.f4 exf4 3.Bc4) 

→ K-Knight’s Gambit (2.f4 exf4 3.Nf3) 

→ other gambits of KGA 

 

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5:                                                                                          

Jerome Gambit (4.Bxf7+) → Jerome Gambit Twice Accepted (JGTA, 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5)  

→ Queen’s Gambit [= JGTA True Queen’s Gambit] (4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+) 

 Q-Pawn’s Gambit (4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.d4) 

→ other gambits of JGTA 

 

This consideration shows that an accepted true gambit being tree” with two (or more) theoretically important “White’s thickest branches” should have a word ‘Gambit’ in the name of each White’s thickest branch. Thus, in KGA the word ‘Gambit’ is everywhere about the sacrifice 2.f4, in JGTA this word is everywhere about the sacrifice 4.Bxf7+. It is necessary to remember that 5.Nxe5+ is an alone theoretically important way after 4.Bxf7+ Kxf7 so “White’s thickest branches” “grow” on White’s 6th move only. This consideration shows that a true Queen’s Gambit exists in JGTA. 

 

 

Here is my unusual addition to the article. It is about the latest using of the name ‘the Queen’s Gambit’ in the modern art. Thus, recently I have read a short exposition of the new film by ‘Netflix’ having this name. This film contains black fantasies so stop, please, young people if they want to risk to watch it without a presence of moral and highly educated specialists of medical sciencesscientific general psychology and pedagogics. The author says by this name that the girl Beth Harmon, a fiction person, is a queen of the chess world and that she makes a large sacrifice in her life. I would like to make a chess conclusion based on this my article: the name ‘The Queen’s Gambit’ of the film can be understood better if it compares this large sacrifice in her life with 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ (the Queen’s Gambit), but not with 1.d4 d5 2.c4 (the Queen’s Pseudogambit): the sacrifice 4.Bxf7+ is true and very large, and 2.c4 is a pseudosacrifice. Moreover, in the Queen’s Pseudogambit White’s Queen isn’t very active, and in the Queen’s Gambit it is very active (for example, GM Hikaru Nakamura’s second win in his blitz games with the Jerome Gambit against GM Dmitrij Kollars28.08.2020, has shown that his Queen has made four opening moves to continue his pressing, and it isn’t a possible theoretical maximum here, of course). Finally, it can be added that the Russian ‘Netflix’s name of this film - “Ход ÐºÐ¾Ñ€Ð¾Ð»ÐµÐ²Ñ‹ (its exact translation is ‘The Queen’s Move’) - can be understood here as having a direct connection with the initial move of the Queen’s Gambit (6.Qh5+).

Jerome Gambit: Strange Enough

 


Sometimes the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ ) is new enough, strange enough, different enough, dangerous enough, scary enough, surprising enough, Jerome enough to make the game look like a simple thing, after all.


Jacobmir - robviz

3 2 blitz, Chess.com, 2020


1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4....Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 


7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Qe7  10.Nc3 c6 11.d4 Nh6


This move is okay, but there was nothing wrong with putting the Knight on f6: 11...Nf6 12.0-0 Kf7 13.f4 Re8, when the King will go to g8 to complete castling-by-hand.

12.O-O Rf8 13.f4 Ng4 

Attacking the enemy Queen - with a plan.

14.Qg3 Qh4 15. Qxh4 Nxh4 


16.f5 g6 

Attacking the advanced "Jerome pawn" is a good idea, in principle, but in this particular case, it helps strand one of the Knights.

17.Bg5 Nxg2 18.Kxg2 gxf5 19.exf5 Bxf5 


I suspect that Black was happy here, with a position that is materially equal, with even the promise of a Bishops-of-opposite-colors endgame and a draw. That is a mis-reading of the position, as 20.h3 now would win a piece.

White plays an even stronger move. Black cannot keep up.

20.Rae1+ Kd7 21.Re7+ Kc8 22.Rfe1 h6 23.Bf4 d5 24.Re8+ Kd7 25.R1e7 checkmate

Jerome Gambit: Act in Haste, Repent at Leisure



Bullet chess. One minute, no increment. Think fast. Move fast. But not too fast...

In the following game, Black takes everything White throws at him. Does it leave him scared - or confident?

Or over-confident?

[Insert laugh track here.]

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 

The Two Knights Defense.

4.Bxf7+ 


Another "impatient" Jerome Gambit, sacrificing the Bishop before ...Bc5.

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Ng6 7.e5 Ng8 


White's e-pawn is aggressive, but, remember, Black is two pieces ahead.

8.Qf3+ Ke8 9.Nc3 d6 10.O-O Be6 11.d5 Bc8 12.e6 


What an annoying "Jerome pawn". But, still...

12...Be7 Black resigned

Ooops... The only way to avoid checkmate is to resign.

Jerome Gambit: Tasty



The following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is a full and tasty game, remarkably so given that it was completed in under 2 minutes, as the time control demanded.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 


7.Qxe5 d6 8.Qc3 Qf6 

A reasonable way to confront White's Queen. It is unclear why he does not subsequently exchange Queens.

9.O-O Bd7 10.d3 Ke7 11.Be3 Bxe3 12.fxe3 Qg6 


13.Nd2 

Connecting his Rooks, which will become active on the f-file. In a game with a slower time control, he would have allowed himself to become distracted by 13.Qxc7. Instead, he permits Black to use up a move protecting against that possibility. Bullet strategy.

13...c6 14.Rf2 Kd8 

Planning to castle-by-hand on the Queenside, but the move is a mistake.

15.Rf8+ 

The Rook pins pieces, right and left.

15...Be8 16.Raf1 Kc7 


17.Qa5+ b6 18.Qc3 h5 

Black wishes to attack, too, and has a role for his Rook.

19.e5 d5 20.Nf3 h4 21.Nd4 h3 22.g3 Ne7 


Radical surgery, but something had to be done.

23.Rxh8 Rd8 24.Nb5+ Kb7 25.Nd6+ Rxd6 26.exd6 Nf5 


Another disappointment for Black: there is too much material hanging to be able to grab the pawn at d6.

27.Rxf5 Qxf5 28.Qxg7+ Ka6 29.Rf8 

Avoiding the trap 29.Rxe8?, when Black would be able to force checkmate with 29...Qf3.

Black's next move is a mistake; his game collapses.

29...Qe5 30.Qxe5 White won on time

2020 Jerome Gambit Championship Cancelled

 

It looks like the Chess.com  2020 Jerome Gambit Championship has been cancelled.

I have contacted the intended Tournament Director, E4fortheL, for further information.

It looks like there will be a chance for a 2021 Jerome Gambit Championship!

Jerome Gambit: Head Spin

The following game is another Jerome Gambit (1.e4  e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) race-to-the-finish 1-minute bullet game. Both players realize that the central "Jerome pawn" center is critical. White, material down, is able to achieve his plans, while Black, appearing stronger, is not. It is another one of those games that makes my head spin.

1.e4  e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

Alternatively, and about equal in strength: 8...Bxe7 9.O-O d6 10.d4 Bd7 11.Nc3 Nf6 12.f4 g6 13.e5 dxe5 14.fxe5 Kg7 15.exf6+ Bxf6 16.Be3 Rhe8 17.Bf2 Re7 18.Rae1 Rae8 19.Rxe7+ Rxe7 20.Nd5 Rf7 21.Nxf6 Rxf6 22.d5 Ra6 23.a3 Bf5 24.c4 Ra4 25.Rc1 Kf6 26.Bd4+ Ke7 27.b3 Rxa3 28.Bc5+ Kd7 29.Bxa3 Black resigned,  Anonymous - Anonymous, 1 0 bullet, lichess.org, 2020. 

9.c3 d5 10.d4 Bb6 11.e5 c5 


White has established his pawn center, with a protected passed pawn at e5; Black immediately attacks it.

12.Be3 cxd4 13.cxd4 Nf5 14.Nc3 Be6 15.O-O-O Nxe3 16.fxe3 Ke7 


Black's two Bishops look dangerous, while, for the time being, White's center has stalled.

17.Rhf1 Rhf8 18.Rf4 g5 19.Rf3 Bg4 20.Rxf8 Rxf8 21.Rd2 Be6 


Okay, who's got a plan?

22.Kc2 Ba5 23.a3 Bc7 24.b4 a5 25.Kb3 axb4 26.axb4 h5 27.e4 


Working for a mobile center, at last.

27...dxe4+ 28.d5 

The center looks troublesome, but, with a lot of time on his clock, Black could find a way for his Bishops to tame it. The problem: he never has a lot of time on his clock.

28...Bf5 29.d6+ Bxd6 30.exd6+ Kd7 


Black's Bishop and passed pawn would seem to give him the edge over White's Knight and blockaded passer, but the game is about even.

White's next move is an error, but neither he nor his opponent notice. The clock is pushing things at a rapid pace and the players are moving more quickly.

31.Rd5 Rf6 32.Nb5 g4 33.Kc3 

Fixing things.

33...Be6 34.Rxh5 Rf2 35.Re5 Rxg2 36.Rxe4 Rxh2 37.Nd4 


A tense position, but still in balance.

37...g3 

A slip. With the safe 37...Bd5 38.Rxg4 Rh3+ 39.Kd2 Kxd6 the game would still be even.

38.Rxe6 g2 39.Rg6 Rh4 40.Rxg2 Rxd4 41.Kxd4 Kxd6 42.Rg6+ Black resigned


Whew! Black trusts his opponent can find the checkmate in time.

Jerome Gambit: A Game of Survival



The following game is not only a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), it is a game of survival and a race against time. After White's 32nd move, Stockfish 11 rates his opponent as over 7 Queens ahead... That's a whole lot of trouble. Certainly the Jerome has been kinder to him on many other occasions. But that is not the whole story. A player wins a chess game if he checkmates his opponent, if his opponent resigns - or if his opponent runs out of time.

I could make reference here to the movie "Forest Gump" and the "Run, Forest, Run!" meme, but I prefer the high speed chase sequences between the cartoon characters Wile E Coyote and the Roadrunner, that often lead off a cliff... 

(I saw another chess player complain about another opponent the other day: He's not strong, he just moves quickly. Well, then don't play blitz...)

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 


7.Qf5+ Kd6 8.f4 Qf6 9.fxe5+ Qxe5 10.Qxe5+ Kxe5 11.c3 


An interesting idea, taking advantage of Black's King in the center of the board. It is relatively rare: The Database has 7 previous games with the move, with White soring 21%. (In bullet chess, just about anything goes.)

11...Kxe4 12.d4 Bd6 13.O-O Nf6 14.Bg5 b6 15.Na3 Bb7 


Except for Black's hyper-developed King, his position looks very good.

16.Nb5 Kd5 17.Rac1 Kc4 

White is interested in checkmating the enemy King. Black is skeptical.

18.a4 Kb3 19.Bxf6 gxf6 20.Rxf6 

Grabbing a pawn while it is available.

21...Kxa4 21.c4 Raf8 

Swapping Rooks is a good, forcing, defensive plan.

22.Rxf8 Rxf8 23.h3 Bg3 24.Rc3 a6 25.Rxg3 axb5 26.Ra3+ Kb4 27.cxb5 Kxb5 


So far Black had defended well, and his extra piece gives him a winning edge.

28.Rc3 Bc6 29.d5 Bxd5 30.Rxc7 Bc6 31.Ra7 Rg8 32.Ra3 


An unfortunate slip, quite understandable when you are taking only a second - or less! - per move. 32.g4 was the only defensive try available.

32...Rxg2+ 33.Kf1 Rxb2 

Black is clearly better, but can he checkmate his opponent before his flag falls? The fact that the game continues for 17 more moves shows that White is skeptical about Black's chances...

34.Re3 Kb4 35.Re7 Rb3 36.Rxh7 Rf3+ 37.Ke2 Rg3 


38.Rh4+ Kb3 39.Kf2 Rg2+ 40.Ke3 Rh2 41.Rh5 Rh1 42.Kd4 Rd1+ 43.Ke5 Rh1 44.Kd6 Re1 45.Kc7 


Catch me, if you can! A whole new idea in fortresses.

45...Rd1 46.Re5 Rh1 47.Rc5 

Clearly, a race to the finish.

47...Rxh3 

See?

48.Rb5+ Kc4 49.Rxb6 Kd5 50.Rb8 White won on time 


(For the record, Black has a checkmate in 28 moves.)
