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.Nc3  

 

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.
