  Honza Cervenka: 46.Ra7?? - Ouch, what a terrible blunder!
Jun-26-06  WMD: Was this in the Interzonal?

  Benzol: <Honza> I was going to recommend 46.♖f1 with the idea of 47.f3 but 46...♕f3 or h3 is hard to meet. How is White going to stop 46...♕f3 anyway? Is White lost before 46.♖a7?

  Honza Cervenka: <Benzol> Well, that's not easy to eliminate black's threats on light squares but if there is not anything better, white still can play 46.e4 Bxe4 47.Re1 Bd5 48.Qe2 after which I don't see any direct win for black although after 48...b4 white should be still very careful. Maybe 46.e4 Bxe4 47.Re1 Bd5 48.Qa3 covering f3 directly and h3 indirectly (48...Qh3 49.Qd3+ and 50.Qxd5) is even better. But I can be missing something here as I did not check these lines with any engine.

Jun-27-06  mack: <WMD> Definitely the Interzonal - Mark Weeks has the same game. For those interested the final standings were:

1.Vaganian (12.5/17pts)
2.Seirawan (11.5)
3.Sokolov (11)
4.Short (10.5)
5.Van Der Wiel (10.5)
6.Torre (10.5)
7.Polugaevsky (9.5)
8.Ljubojevic (9.5)
9.Andersson (9.5)
10.Rodriguez (8)
11.Sax (8)
12.Jansa (7.5)
13.Quinteros (7.5)
14.Petursson (7)
15.Gutman (6.5)
16.Zunian (6)
17.Partos (4)
18.Gonzalez (3.5)

(Places 4-6, 7-9, 10-11, 12-13 decided on tiebreaks.)

Ah, how I long for a good Interzonal again.

  suenteus po 147: I shudder to think how Vaganian faired at the Candidates despite such an impressive win at the Interzonal.

<Ah, how I long for a good Interzonal again.> I hear you, mate!

Jun-23-20  Retireborn: As well as the blunder at the end, Polu also misses a snap mate with 36.Ra8+ Kh7 37.Rh8+ Kxg6 38.Qg4#

Had he won this game instead of losing it, he might still have qualified for the candidates again.

  perfidious: <Retireborn>, Polugaevsky might have had a shot despite this game if he had not also thrown away a perfectly good position in Polugaevsky vs Quinteros, 1985, played two rounds later.
