GM Amir Bagheri Annotates...


Robert Byrne - Bobby Fischer
Sousse Interzonal (12), 1967


1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bc4 e6 7.Bb3 b5









8.f4

I should point out that in this particular variation, partially as a consequence of this game, 8.0-0 Be7 9.Qf3 has replaced 8.f4 as the main theoretical line these days.  White generally strives for an advantage with early piece play, only aiming for f4-f5 later on.

8...Bb7 9.f5 e5 10.Nde2 Nbd7

The pawn grab 10. … Nxe4 is a bit greedy, but certainly not out of the question.  11.Nxe4 Bxe4 12.O-O Bb7 13.Nc3 Be7 14.Nd5 Bf6 15.Be3 Nd7 16.Qh5 gave White a promising position for the pawn deficit in Dely-Bednarski, Zinowitz 1964.

10. … Bx4? loses simply to 11.Nxe4 Nxe4 12.Qd5.

11.Bg5 Be7 12.Ng3

Adding pressure down the c-file.  12…0-0 looks natural enough but allows White to carry out his plan.  13.Bxf6 Nxf6 14.Nh5 Qb6 15.Nxf6+ Bxf6 16.Qd3 Bg5 (White cannot castle either side, but he is still better as he will have an unopposed knight on d5) 17.Bd5! Rfd8 18.h4 Bh6 19.g4 Bf4 20.Bxb7 Qxb7 21.g5 Rac8 22.Nd5 Rc4 23.c3 Rdc8 24.f6 Kh8 25.fxg7+ Kxg7 26.0-0 with a clear plus for White, Susnik vs. S. Nikolic Ljubljana 1996.








12...Rc8 13.0-0

Surprisingly enough this natural move is a serious mistake, although this is only shown up by the brilliance of Fischer’s next move.  White has two stronger alternatives:

a) 13. Nh5 Nxh5 14. Qxh5 0-0 15. Bxe7 ( 15. h4 b4 16. Nd5Bxd5 17. exd5 Nc5 18. 0-0-0 a5 19. qg4 a4 20. Bc4 b3 gave Black a strong attack, R Byrnes vs. Bouaziz. 1967) 15. … Qxe7 and Black has nothing to fear Black has won this positional battle Voss vs. Trisic concluded 19.c4 bxc4 20.Bxc4 Rfc8 21.Bb3 Nxd5 22.Qxa6 Qh4+ 23.Kd1 Qd4+ 24.Ke2 Qe3+ 0-1 and White resigned.

b) 13. Bxf6 Nxf6 14. Nh5 is a more direct method of trying to win the battle for the d5 square, but Black is also well armed against this response : 14. … Rxc3! (a typical exchange sacrifice and yet another point of … Rc8) 15.Nxf6+ Bxf6 16.bxc3 Bxe4.  Black has good compensation for the exchange : a pawn, the bishop pair and weak white pawns to aim at.

13...h5!!

Characteristically it’s Fischer who find the antidote to one of his own plans!  Black use the very fact that he hasn’t castled to lunge forward with this pawn, a multi-dimensional move:

  1. it prevents Nh5;

  2. it prepares …. H5-h4, attacking the knight which defend the crucial e4-pawn;

  3. it begins a surprisingly effective attack on the white kingside.

It’s not too early to say that White is already in big trouble!

14.h4

This move looks ugly, but what else is there? 14.Bxf6 Nxf6 brings White no relief after:

a) 15.Qf3 Rxc3! 16.Qxc3 h4









Analysis Diagram: after 16...h4

And Black has a vicious attack, for example: 17.Nh1 Qb6+ 18.Nf2 Qc6 and White is killed down the long diagonal, or: 17.Ne2 Qb6+ 18.Kh1 Nxe4 19.Qh3 Ng5 20.Qg4 h3 21.Rg1 Ne4 22.Raf1 Nf2+ 23.Rxf2 Qxf2 24.Qxg7 hxg2+ 25.Rxg2 Qxe2 26.Bxf7+ Kd8 27.Qxh8+ Kc7 and Black mates, Bednarski vs. Lehmann 1967.

b) 15.Nd5 h4 16.Nxf6+ gxf6! 17.Nh1 bxe4 18.Qg4 d5 and Black is already winning.  Thorstein vs. Ghitescu concluded 19.Rad1 Bc5+ 20.Nf2 Ke7 21.Rfe1 Bxf2+ 22.Kxf2 Qb6+ 23.Kf1 Rhg8 24.Qxh4 Rxg2 and White threw in the towel.

14...b4








15.Bxf6

Or 15.Nd5 Nxd5 16.Bxd5 Bxg5 17.hxg5 Bxd5 18.Qxd5 Qxg5 and Black is in total control.

15...Bxf6

15…Nxf6 is just as good: 16.Nd5 Nxd5 17.Bxd5 Bxd5 18.Qxd5 Bxh4 is horrible for White.  16.Nd5 Bxh4  And so White has control over d5, but his kingside is fatally weakened.  This is not a good deal!

16.Nd5 Bxh4 17.Nxh5 Qg5

Black has now the luxury of an open h-file which to attack.  I guess it could be said that White has won a battle (of the d5-square) but has lost the war.  Byrne gamely puts up a fight, but from here the result is never in doubt.








18.f6 g6 19.Ng7+ Kd8

Threatening ... Bxd5 followed by ... Qe3+

20.Rf3 Bg3

Now Black threatens …Qh4

21.Qd3 Bh2+ 22.Kf1 Nc5 23.Rh3

23.Qe2 Bg3 is terminal.

23...Rh4 24.Qf3 Nxb3 25.axb3 Rxh3 26.Qxh3 Bxd5

White has even lost control over d5!

27.exd5 Qxf6+ 28.Ke1 Qf4 0-1
