Playoff for 4th place

Following the main tournament, the three players with the same number of points played a playoff at the same point to determine the fourth qualifier. Each player met each of his competitors three times. Since Short and van der Wiel again stayed tied, the better Sonneborn-Berger rating from the interzonal tournament decided in favor of the Englishman
