Chessgames.com Chess Event Description
Amsterdam IBM (1973)

The 13th IBM tournament took place in the main hall of the RAI building in Amsterdam, the Netherlands from July 17 (Round 1) to August 4 (Round 15), with rest days on July 21, 26, 29 and August 3. Round 6 started on the same day as Round 1 of the Petropolis Interzonal (1973). From the top ten players in the world, Boris Spassky (Elo rated as #4) and Tigran Petrosian (#7) participated. The other fourteen were Jan Smejkal (#16), Laszlo Szabo (#28), Lubomir Kavalek (#28), Ulf Andersson (#35), Ivan Radulov (#47), Zoltan Ribli (#51), Albin Planinc (#51), Miguel Quinteros (#56), Drazen Marovic (#100), and the Dutchmen Jan Hein Donner (#100), Jan Timman (#116), Bert Enklaar (#145), Hans Ree (#187) and Kick Langeweg (#221). Six players were perhaps more tired than the rest: Smejkal, Radulov and Quinteros who had played in the Leningrad Interzonal (1973), and Szabo, Andersson and Timman who had played in the 2nd AVRO (1973) tournament (12-29 June). Not counting Spassky, Petrosian, Szabo, Ribli and Planinc, who arrived straight from the European Team Championship (1973) in Bath, England (6-13 July). Spassky was surrounded by journalists, after he lost his world championship title to Robert James Fischer the previous year, but did not want to talk about his experiences in Iceland.

In addition to the main event (this page), there was also a masters' group (B-group) and several minor events. The opening ceremony took place in Hilton Hotel on July 16. The drawing of lots was conducted by mayor Ivo Samkalden, with the help of Petrosian, Spassky and Donner. Round 1 started in the presence of Ineke Bakker, FIDE's General Secretary and sort of first lady of chess. According to Harry Golombek, neither player made an auspicious start and it was Planinc who made the running. At the end of Round 9 he was leading with 7½ points, ahead of Petrosian 5½, Donner, Kavalek, Ribli, Spassky, Szabo and Timman all with 5. Spassky's position was explained by his loss to Donner (in Round 9). Petrosian beat Langeweg in the next round, while Planinc drew Kavalek. In Round 11, Petrosian beat Planinc, reducing Planinc's lead to half a point (Planinc 8, Petrosian 7½). Planinc slipped back further when, in Round 13, he lost to Quinteros, so that now both Petrosian and Planinc had 8½. They remained even until the end of the tournament.

The application of the Sonneborn-Berger system brought Petrosian the first place, but the prize money was equally shared. For Planinc, it was his greatest success since the Vidmar Memorial (1969). Kavalek secured third place by a draw with Szabo in the last round, whilst Spassky levered himself up to fourth by beating Timman. Spassky returned to form by winning the USSR Championship (1973) in October.
