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.

The 12 qualifiers from the Interzonals were joined in the Candidates Tournament by three seeded players: Smyslov, Korchnoi, and Ribli (no. 2-4 from the previous tournament). The final spot went to Spassky, who was given a wild card by the organizers.

These 16 players first played a round-robin in Montpellier in October and November 1985, from which the top 4 would qualify for the knock-out phase.

A playoff match for fourth place was held after the main event. It ended 3-3, and Timman advanced because he had more wins during the tournament (4 against Tal's 3).

The top 4 from the round-robin played a series of matches in 1986, the winner of which (Sokolov) in turn got to play Anatoly Karpov in a final match in Linares to determine the championship challenger.

							Andrei Sokolov	7½
	Tilburg, Jan-Feb 1986						Artur Yusupov	6½
		Artur Yusupov	6
		Jan Timman	3

Karpov had earned the special privilege of being seeded directly into this match as part of the agreement regarding the controversial championship matches of 1984, 1985, and 1986.

Karpov won, thus earning the right to face Kasparov in a championship match for the fourth year in a row.

The match was played as the best of 24 games. It ended in a 12-12 tie, Kasparov retaining his title.
