A Correction

In my email comments to Yury Bukayev about the line we were discussing, 1.e4 e5 2.Nc3 Nc6 3.Bc4 h6 4.Nf3 Nd4, 5.Bf7!?, I did not show much enthusiasm. In short order, I got a very bright email, enlightening me.

How do you do, dear Mr. Kennedy!

Dear Rick, thank you very much for your 2 letters! But I disagree with your appraisals of 5.Bxf7 and of 5.Nxe5. I suggest you discuss with me or publish (it will be better) my following analysis (5.Bf7! Kf7 6.Ne5 Ke6 7.Qh5+- ) and my words about 5.Ne5 Qg5-+:

1.e4 e5 2.Nc3 Nc6 3.Bc4 h6 (Vienna game: Max Lange variation) 4.Nf3 (Italian game/ Three Knights game) …Nd4?

Paragraph 1. 5.Bf7! Kf7 6.Ne5 Ke6 7.Qh5!? (White stands better.)

I)  7…Nc2 8.Kd1 Na1 9.Qf5 Kd6 (9…Ke7 10.Ng6 Kd6 11.Qd5 mate) 10.Nc4 Ke7 11.Nd5 Ke8 12.Qg6 mate;

II) 7…Qg5 8.Qf7 Kd6 [8…Ke5 9.d3 (with the idea 10.Bf4 mate) …Nc2 10.Kf1!?+-] 9.Qd5!? Ke7 10.Qd4 Qg2 11.Nd5 Kd8 12.Rf1 White stands better.

III) 7…Qf6 8.Ng6!? (White stands better.)
     A)    8…Nc2 (8…Rh7 9.Qd5 mate) 9.Kd1 Na1 10.Qd5 mate;
B)   8…Qg5 9.Nf8!? Ke7 10.Ng6 White stands better.
C)   8…c6 9.Qg4!? Kf7 10.Nh8 Ke8 11.0-0!? Nc2 12.Rb1 Nge7 13.e5 White stands better.
D)  8…d6 9.Nf8 (or 9.Nd5) …Qf8 (9…Ke7 10.Nd5!? Kf8 11.Nf6+-) 10.Qd5 White stands better.
E)  8…Ne7 9.Nd5 Qg5 (9…Qg6 10.Nf4+-; 9…Qf7 10.Ngf4+-) 10.Qg5!? White stands better.

IV) 7…g6 8.Qg6!? (White stands better.)
A)  8…Ke5 9.f4 Kf4 10.0-0+-;
B)  8…Nf6 9.Qf7 Ke5 10.f4 Kd6 (10…Kf4 11.0-0 Ke5 12.d3+) 11.e5 with the very strong attack;
C)  8…Qf6 9.Nd5!? Qg6 10.Ng6 (White stands better.) …Nc2 11.Kd1 Na1 12.Nc7 (or 12.Nh8) …Kf6 (12…Kd6 13.Na8 Rh7 14.Nf8 White stands better.) 13.Nh8 Rb8 14.b3 (with the idea 15.Bb2) +-

V) 7…Nf6 8.Qf7 Ke5 9.f4 Kd6 [9…Kf4 10.0-0 Ke5 11.d3 (with the idea 12.Bf4 mate) …g5!(11…Nc2 12.Bf4 Kd4 13.Qc4 mate) 12.Rf6!? c6 (12…Qf6 13.Qd5 mate; 12…Qe7 13.Rf5+-; 12…Bg7 13.Rg6!? White stands better.) 13.Be3 White stands better.] 10.e5 with the very strong attack.

Paragraph 2. 5.Ne5?! Qg5.

Probably, Black stands better both after 6.Nf7 and after 6.Bf7, because Black has a very strong attack in both cases: Qg2, Nf3, d5, Bg4.

Do you agree with me, dear Rick? I suggest you to discuss with me or to publish (it will be better) my analysis.

Best wishes! Yury V. Bukayev (“Bruno’s Chess Problem of the Day”)
