The New Opening Theory Of ‘3-Check Chess’ & JG (Part 1)



                                   The New Opening Theory Of ‘3-Check Chess’ & JG (Part 1)   

  

(by Yury V. Bukayev) 

 

 

Dear reader, you know already a lot of very important facts about theory of the standard system of the Jerome gambit (JG) in chess, but, it maybe, you take an interest in similar board games too. This my analytical research is about the board game ‘Three Checks chess’ ( = ‘3-Check chess’ = ‘Three-Check chess’ ) mainly, although you can find something new in theory and psychology of the Jerome gambit in ordinary chess in the note. 

   

The article What is 3-Check chess? ( https://support.chess.com/article/351-3-check) informs us about rules of this popular board game: “Normal [chess – Yu. B.] rules apply, but you can also win (or lose!) a game by checking (or getting checked) 3 times in total”. The portal Chess.com places this board game near Fischer Random chess in its list ‘Chess Variants’, above other “chess variants”, and it is right.    

 

Here is my brief analysis of 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ with my theoretical inventions for this difficult board game. 

 

(Three Checks chess) 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5? 4.Bxf7+! AN [It’s a very strong move.] 4…Kf8! [4…Kxf7?? 5.Nxe5+!, and White wins immediately, because his next move will be his third check.] 5.Bxg8!? [There are some else good ways here, for example 5.0-0!?.]  

 

{Let me make here also a note for JG in ordinary chess. Thus, in ordinary chess, according to my following new idea, this new Jerome gambit way (5.0-0) is a notable psychological (or handicap) continuation of White’s style (4.Bxf7+), because 5…Kxf7! here leads to White’s much more strong attacks, than after 4…Kxf7!. Thus, for example, 5.0-0 Kxf7 6.Nxe5 Nxe5!? 7.Qh5+! g6?? 8.Qxe5 wins, 7.d4! is also strong for White, because, first of all, the response …Qh4 doesn’t play that main winning role in theory. You remember that my analysis from the post ‘Anatoly Karpov & Jerome Gambit (Part 5)’.}  

 

5…Kxg8 [The most aggressive alternative is 5…Bxf2+. After 6.Kxf2!? (6.Kf1!?) 6…Qe7! (with the idea 6…Qc5+! and a winning Queen’s check further) 7.d4 exd4 8.Nbd2!? White has the advantage.] 6.Qe2! [This move has a threat 7.Qc4+ with a final Queen’s check further (1:0). After 6.c3!? d5 Black has a more strong counter-play.] 6…d5 7.exd5 Qxd5  

 

Here White should choose among the following good ways. 

 

I)8.Nc 

 

A)8…Qf7 9.Ne4! Bb6 [9…Nd4 10.Nxd4! Bxd4 11.Nf6+! gxf6 12.Qg4+, 1:0] 10.Nfg5 Nd4 [10…Qd5 11.Qh5! with the idea 12.Nf6+!, but not 11.Nf6+ gxf6 12.Qh5 Bxf2+! 13.Kd1 Bg4+ or 13…Qxd2+, 0:1] 11.Nxf7 with a winning advantage 

 

B)8…Bxf2+ 9.Kf1!? [9.Qxf2!? with the idea 10.0-0 is normal too, but 9.Kxf2?? Qc5+!, and Black wins by his third Queen’s check on the next move] 9…Qc5 10.Ne4 with a winning advantage [With the threats 11.Nxc5, 11.Nf6+, 11.Nxf2 etc. If 10.Qxf2?? then 10…Qc4+!, 0:1]    

 

II)8.0-0 with the same plan, with an advantage 

 

We can see the first analytical steps here.

Jerome Gambit: Uh, Yeah, Okay

My guess is that if you ever found yourself down a Queen and 5 pawns in the endgame, you might be willing to resign.

Even if you had been playing against the Jerome Gambit 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+.

In the case of the following game - the players shall remain nameless - Black was facing the Semi-Italian (or Anti-Fried Liver) Jerome Gambit 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.Bxf7+.

Soon, things became dire for the defender. 


Time to resign?

Well, no.

Maybe the two competitors were friends and were having a laugh. Or maybe Black simply wanted to see if White could avoid a draw by stalemate.



Checkmate
Uh, Yeah, Okay, stalemate avoided.

Has this happened before? Almost.

Try this one.

Here the defender against the Jerome Gambit winds up with an extra Queen and 4 pawns, with the game ending up like this


Checkmate

And, once more, as a warning to White that "If you strike at the King (with the Jerome Gambit), you must kill him" here is another scary predicament from The Database


Ending up
Checkmate

(I know that some chess sets have an extra Queen for each side, to be ready if a pawn promotes. I have seen players who need another Queen turn a Rook over to represent a Queen and play with it that way. But what if you run out of Rooks, too?)

Jerome Gambit: Mattoscacco



Long-time contributor to this blog Yury V. Bukayev points out an Italian language video focusing on the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+"Apertura Imbattibile di Scacchi | Gambetto Jerome" (and even mentioning this blog with a screen shot of "Jerome Gambit: I Am Not Encouraging "Perfect Chess").

One of a number of presentations by Mattoscacco, this video takes a light-hearted approach as it touches on main line Jerome play, as well as taking a peek at 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Bxf7+ and 1.e4 e5 2.Nf3 Nf6 3.Bc4 Nxe4 4.Bxf7+

Although my knowledge of Italian is quite limited, I enjoyed looking at the variations given. 

At 17 minutes, it is worth a look - and listen.

Jerome Gambit: Four Squared

 


A short YouTube video by Four Squares (@FourSquares) showing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), "100 Chess traps #48 Jerome gambit", is one of many on the site. 

The short video showcases a quick checkmate. Although unidentified, the game is blackburne - karmmark, Jerome Gambit thematic tournament, ChessWorld.net, 2007

Check it out.

Jerome Gambit: Refuted.


The nightmare of playing a "refuted" opening is that sometimes actually gets refuted.

Faster time controls help the attacker. Surprise helps.

Sometimes it is not enough.


pablosko - yooooooooo

3 0 blitz, lichess.org, 2022

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 


First appearing in Sorensen - X, Denmark, 1888 (1-0, 27).

7.O-O Nf6 8.dxe5 

White is under pressure, but taking the enemy Bishop when he has the opportunity (8.dxc5) is probably more helpful.

8...Ng4 

9.Qd5+ 

Striking out, but it does not save him.

9...Ke8 10.h3 Bxf2+ 11.Rxf2 Qxf2+ White resigned

Checkmate is next.

It does not always have to end this way.

Jerome Gambit: What Can We Learn? (Part 3)


[continued from the previous post]

perrypawnpusher - auswebby

3 days/move, "Giuoco Piano Game", Chess.com, 2022


28.Nxd5 

Played with a sense of resignation.

28...Rxc1 29.Rxc1 Rxd5 

As long as Black keeps his two pieces and King active, he will have the advantage.

30.Re1 Rd7 31.g4 Kb6 


32.Re5 Rd2+ 33.Re2 Rxe2+ 34.Kxe2 Kc5 


I know, I know, why haven't I resigned?

Hold on, I have one joke left.

35.Kd3 Kb4 36.f4 a5 37.Kc2 Ka3 38.Kb1 

38...Bd5 

After 38...Bxb3 I intended to resign, things looking hopeless after 39.axb3 Kxb3. Imagine my surprise after the game when Stockfish 15 pointed out that 40.g5 Kc4 41.g4 g6 42.f5 gxf5 43.gxf5 Kd5 44.f6 Ke6 45.Ka2 h5!? 46.gxh6 ep Kxf6 47.h7 Kg7 48.Kh3 Kxh7 49.Ka4 Kg6 50.Kxa4 would be a draw.  

So that's why auswebby played the text move.

39.g3 Bf3 40.g5 Be4+ 41.Ka1 Bf5 42.b4 axb4 43.g4 Bxg4 44.f5 


Now if 44...Bxf5 45.g6 Bxg6 (or 45...hxg6) the position would be a stalemate draw.

44...b3 45.axb3 Bxf5 46.g6 Bxg6 

White resigned

Excellent game by auswebby!
