Kibitzer's Corner
Mar-06-04  jgbrody: This is one of my personal favorites. I enjoy games that feature two Rooks vs. Queen imbalances and strong attacks by both players. Black threatens mate next move three moves in a row! But after 38. ...Kg7 or Kh7, 39. Rxf7+ Kh6 40. Rh8+, black loses the Queen!

I believe Fischer may have seen the outcome of this game at move 32. Bd5! This move (it seems to me) sets up the trade of White's Queen for Black's Rook and Bishop and ultimately the wiining combination.

In my opinion, a simply brilliant game by Fischer.

Jan-22-05  lopium: Ah, what a player! Fischer was really strong again.

  Richard Taylor: Yes - a great game. The imbalance.
Aug-06-06  Gouki: why didnt black take the knight on 20....Bxb5?

  Phony Benoni: <Gouki> Perhaps he was worried that 21.axb5 would leave his knight on b4 with no retreat and in danger of being trapped when White plays c3.
Aug-06-06  Gouki: oh I didnt see that. thanks.
Aug-06-06  reynolds: what about 20..Bxb5 21. axb5 a4 22. Nc1 a3 ?

<reynolds><20...Bxb5 21.axb5 a4 22.Nc1 a3> OK, except that White would probably play 22.Nxc5 instead, following with 23.c3 and the knight is in trouble.

Oct-21-06  vertho: According to Fischer, his filosophy against the dragon was "sac, sac, mate". Why did fischer have so little respect for the dragon? what makes this variation different to other fianchetto variations? Why not "sac sac mate" in every fianchetto on the king side?

  Benzol: <vertho> Didn't Fischer also say that when thumbing through an edition of Informator there was a high percentage of White wins and that amateurs were beating Grandmasters with it when the Yugoslav Attack first made it's appearance.

Of course there were other games like this one
Fischer vs C Munoz, 1960 and the game against Charles Powell which is discussed in the thread of the Munoz game.

Don't know about other Sicilian fianchetto systems though.

Jul-28-07  Helios727: Ironically, this was not a Yugoslav Attack. White transposed into the Classical Dragon.

  Eyal: Olafsson could have tried 34...Kg7/h7 (releasing the f pawn from the diagonal pin), but then White wins by 35.Ra8 Qd6 (35...Qe7 36.R1a7 and 37.Rxf7+) 36.R1a6 (36.R1a7? Kh6! 37.Rxf7 Qb6, and now 38.Rh8+ Kg5 39.Bc4 loses to 39...Bf4!) 36...Qe7 (36...Qd7 37.R6a7 Qb5 38.Rxf7+ Kh6 39.Rh8+ Kg5 40.h4+ Kg4 41.Be6+ and mate - that's why the black queen has to stay on 6th rank; 36...Qc7 37.R6a7 Qb6 38.Rb7! Qd6 39.Rxf7+ etc.) 37.R6a7 Qd6 38.Rxf7+ Kh6 39.Rh8+ Kg5 40.Bc4! and now the threat of Be2&h4+ is decisive: 40...Qd1+ Rf1; 40...Bf4 41.Be2 (defending against the mate threat on d1).

In addition to the 2 Rooks vs. Queen imbalance, it's worth noting the role played in the final sequence by the bishops of opposite color - an example of their presence actually being an anti-drawing factor which helps the attacker, since the opponent's bishop cannot defend the squares his bishop is attacking

Oct-09-11  DrMAL: Here is third much simpler example showing importance of deep opening preparation. After 8.O-O black can try to win pawn with 8...Qb4 via 9.Bb3 Nxe4 expecting 10.Nxe4 recapture. If 10.Nxe4 white still can get full compensation for pawn but instead white can play 10.Nxc6! dxc6 11.a3! nearly decisive.

With less understanding of opening 8...Qb4 could be considered novelty perhaps even trap, it is avoided here because players know better or they can sense the error and figure out simple refutation here OTB. The better one knows openings, their many hows and whys, the easier it becomes to make correct assessments and good plans when new move is encountered.

In game both players created and sustained nearly equal double-edged game from strong understanding and accurate play. Black finally made one slip-up with 31...Qf8?! (instead of Qe8 or Qd8) and Fischer took maximal advantage of it, enough to win.

Mar-14-12  jerseybob: As awful as it looks,what is the refutation of 18..gf?!

  Honza Cervenka: 31...Qf8 was an unfortunate slip from black's part. After 31...Bd7 or 31...Qd8 32.Bd5 Bc6 black is hardly in any real danger of the loss despite of slight material advantage of white.

35.Ra7 is better than the text 35.Rf1.

  ChessHigherCat: SF seems a bit skeptical of 36...Bxg3?

1) +132.67 (37 ply) 37.Ra8+ Qf8 38.Rxf8+ Kxf8 39.Rxf7+ Ke8 40.hxg3 g5 41.Rc7 Kd8 42.Rxc5 Kd7 43.Bf7 Kd6 44.Rd5+ Kc6 45.Rxe5 Kd6 46.Rxg5 Ke7 47.e5 Kd7 48.e6+ Ke7 49.Bh5 Kd6 50.e7 Kxe7

Some one recently said that that's the highest possible score, meaning that

1) mate is certain according to the tablebase but 2) SF doesn't know in exactly how many moves.

Maybe I'm misquoting but that seems self-contradictory to me. If mate is certain it must either be known in the tablebase or else SF has calculated it out, and either way the number of moves until mate is known.
