Toluca Interzonal 1982
Compiled by Tabanus
--*--

In order to select a challenger for the World Champion Anatoly Karpov, it was necessary to qualify eight players for the Candidates quarterfinal knock-out matches that would conclude in 1983. Two players, Viktor Korchnoi and Robert Huebner, were qualified from having reached the Korchnoi - Hübner Candidates Final (1980). The other six would qualify from three tournaments: Las Palmas Interzonal (1982), Toluca (this page), and Moscow Interzonal (1982). This was the first time FIDE split the interzonal stage into three parts, instead of two as in 1979, 1976 and 1973. (1)

The original plan was to hold the "American" Interzonal in Mexico City, but sponsors there backed out. (2) The peso was devalued, and the government could not meet the financial requirements. (3) The tournament was scheduled for Iceland in September. But this met huge protests from the top players, who had accepted invitation to other events in September. (3) The Mexicans came up with new sponsors, and with two weeks delay, (2) the tournament was held in Toluca de Lerdo (4) about 63 kilometers SW of Mexico City. Qualifying from the zonal tournaments were Nunn from Marbella Final (1982) and the Leiden Zonal Playoff (1982), Rodriguez from Manzanillo (1981), Kouatly from Sharjah (1981), Hulak from Budva (1981) and Zagreb Zonal Playoff (1982), Torre from Hong Kong (1982), Rubinetti from Morón (1982), Yusupov from Yerevan (1982), Ivanov from Montreal (1981), and Seirawan from the US Championship (1981). (5) Seirawan had been training in a rented lodge, well-stocked with food, in the environs of his native Seattle together with John William Donaldson and the opening expert Zoran S Ilic. (6) He would be helped in Toluca also by Lubomir Kavalek. (6) Four players, Portisch, Spassky, Polugaevsky and Adorjan, were qualified from having reached the Candidates matches in 1980. Balashov was perhaps selected by FIDE according to rating.

The venue was "a luxury hotel" at 2600 m.a.s.l. (2) Some participants were to begin with taken by altitude sickness. (2) The tournament was opened by the Governor of the State of Mexico <Alfredo del Mazo González>. (7) There was a speech by the arbiter <Carlos Encinas> (8) who said this was "the most important chess event in North America in the last 10 years". (7) Most players had been there for several days or even a week to allow for acclimatisation, whereas Nunn and his second Murray Chandler had arrived on the 9th. They were shocked to discover that Round 1 was to start on the 10th despite prior notification of the 11th. (9) Nunn struggled badly in rounds 1, 2 and 3 due to the seven hour time difference. He swindled Hulak in Round 4 (44...Re2!!), and shared the lead after Round 6, but fell back thereafter. (9) After five rounds, Adorjan held the lead with 3½ points. Adorjan showed some fine attacking play against Hulak in Round 3, but then played miserably. (9) Polugaevsky started poorly, and blundered against Torre, but recovered well to post a respectable score. Spassky surprised Adorjan in Round 10 with the tricky English Defense. As early as move 9, Adorjan fell into a disastrous trap. In "ultra-hypermodern style", (10) Spassky let him set up a pawn center with 1.c4 b6 2.d4 Bb7 3.Nc3 e6 4.e4. He counterattacked with 4...Bb4 5.Bd3 f5, and Adorjan responded with 6.Qh5+ g6 7.Qe2 Nf6 8.f3

Spassky now played 8...Nc6!, as suggested by Raymond Keene in the January 1978 issue of Modern Chess Theory. (10) This made it difficult for Adorjan to maintain his pawn phalanx. He blundered with 9.e5?, falling headlong into Spassky's trap with 9...Nxd4! After 10.Qf2 Nh5! there was no recourse in 11.g4 because of 11...fxg4! 12.Qxd4 gxf3 13.Qg4 (13.Qf2 Bc5 14.Be3 Bxe3 15.Qxe3 f2+ is not better and 13.Be4 Bxc3+ 14.bxc3 Qh4+ is also bad) 13...f2+ 14.Kxf2 O-O+ 15.Ke1 Bxh1, winning material. Discouraged with himself, Adorjan went through with 11.Qxd4, even if 11...Bc5! trapped his queen in the middle of the board. (10) According to Nunn, Spassky did not seem to take the event seriously, (9) but he was within a whisker of reaching a playoff when he lost his way in a winning position against Ivanov in the last round. Torre’s tactical gifts were on display and earned him five consecutive wins. Regardless, Nunn was critical of Torre's opening play and clock handling, claiming that these factors would weigh against him in a Candidates match. (9) Portisch put a poor start behind him and moved into a higher gear for the second half of the event. And so the highest rated player won, shared with Torre from the Philippines.

Tournament category: 12 (GM norm 8 points, IM norm 5.5 points). (9)

Portisch and Torre advanced to the Candidates matches:

Ribli - Torre Candidates Quarterfinal (1983)
Korchnoi - Portisch Candidates Quarterfinal (1983) Smyslov - Hübner Candidates Quarterfinal (1983)
Kasparov - Beliavsky Candidates Quarterfinal (1983)

Portisch qualified for the Candidates for the sixth time! He was at his best around 1982, but met the "terrible" Viktor Korchnoi in the quarterfinal. Seirawan was "extremely disappointed", (11) but he was only 22 and his performance was still the best by an American in 10 years. (12) For Spassky, it would be his last Interzonal (he was chosen by the organizer to play in the Montpellier Candidates (1985)). According to ChessBase, his relations with the Soviet Chess Federation was finally broken during the event. (13) Or perhaps after the event: 'Toluca' was the first Interzonal ever where no Soviet players qualified. (14) The Canadian champion Ivanov had earned his IM title only last year, and made a good figure. He missed the GM norm by half a point. According to Wikipedia he received the GM title long after it was due, in 2005, partly because the Soviet chess federation refused to recognize his earlier achievements after he ran off to Canada in 1980. (15) Torre was the first Asian ever to qualify for the Candidates. (16) In a sense, this was a vindication of FIDE's democratic world-wide qualifying system. On the other hand, the players in Toluca were dissatisfied with only 13 games, because only a single loss might be difficult or impossible to repair. They felt that their play was "hard, tense and nervous and the quality thereby suffering". (17)
