JG: The New in Its Opening Theory, in Its Psychology (Part 9)   

(by Yury V. Bukayev) 

 

 

As a further development of my Part 2 (the post of October, 16, 2020 on Rick Kennedy’s blog), this continuation of my theoretical research on the standard line of the Jerome gambit (JG) is about position after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qh3+! Ke7 8.Qc3!? Bd6!? 9.f4!. If your very cautious opponent (Black) is surprised by 7.Qh3+, then, most probably, he’ll prefer to play 7…Kf7: I proved it in some of my previous parts including my Part 8, where the new way of fight against the defence 7…Ke7 8.Qc3!? Bxf2+!? was considered (the post of September, 22, 2021 on Rick Kennedy’s blog). Nevertheless, you should be ready to meet this very important position in such game too.    

Here Black can find enough good defence where he returns no pieces on its first stage: 9…Ke8! N [The moves 9…Kf7!? N and 9…Kf8!? N are also possible. These my three new moves-inventions have the same idea - to open key squares for Black's Queen and Black's Bishop] 10.0-0! [10.fe? Qh4! 11.Kf1 Qf4! 12.Kg1 Be5!?, and Black wins. Although White can win here by traps 11.g3 Qe4 12.Kf2 Qh1 13.ed Qc1 14.Qg7 (or 14.Qe5 Kd8 15.dc#) 14…cd 15.Qh8 Kf8 16.a4 b5 17.ab Bb7 18.Ra4 Qb1 19.Rf4 Ke7 20.Qg7 +-, the probability of these Black’s mistakes isn’t very large.] Here Black should play 10…Nf7 or 10…Nc6. In both cases the move 11.Qxg7 isn’t good, White has two enough good ways: 11.b3 and 11.d4. It’s enough rare case in theory of JG, where on this opening stage White regains no pieces and lets opponent’s King retreat back from the centre, but can create very large difficulties for the opponent. Even a very cautious opponent can think here mistakenly that it’s very easy to achieve the score “0:1”, so he’ll start to make “active” moves without his usual caution.     

For example, here is one of “active” variations of play: 10…Nc6 11.b3 Bb4 12.Qe3 d6 13.Bb2 Bc5 14.d4 Bb6 15.c4 Qf6 16.e5 Qh6 17.c5 Ba5 18.a3 Nge7 19.b4 Bxb4 20.axb4 Nxb4 21.exd6: Black has an extra Knight, but White’s attack is strong.  

Here it becomes clear that my else new invented ways (N) - 9.0-0!?, 9.d4 Nc6 10.a3!? (10.0-0!?) - are enough good too. 

Of course, the Natural star Jerome gambit deferred (the strong deferred line of JG - the post of September, 17, 2021 on Rick Kennedy's blog) will be much more attractive for a lot of experts of the modern chess opening theory than the standard line of JG, but the defence 6…Ke6 after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ requires their new attention and large revision already now, we can understand finally.
