Short, van der Wiel, and Torre contested a playoff, also in Biel, for the fourth and final spot in the Candidates Tournament. Short and van der Wiel were tied with 3½ points each, while Torre scored 2 points, so Short qualified on a better tie break score from the main event.
The highest placed non-qualifying player from each Interzonal met in London in September 1985 to play for the position as first reserve in the Candidates Tournament. Speelman won with 4½ points, ahead of Gavrikov (4) and van der Wiel (3½). No reserve was needed, however.
