  • Players marked in green advanced to the 1959 Candidates tournament.

  • Smyslov, as the loser of the last World Championship, and Keres as the runner-up in the previous Candidates were seeded into the 1959 Candidates.

  • Bronstein's last round loss to Cardoso, one of the great sensations in Interzonal history, and his first-ever loss in Interzonal play, knocked him out of contention. He never again made it into the Candidates, after playing in the first three. He scored well enough to qualify in the 1964 Interzonal, but was disqualified by the rule limiting the number of people that could qualify from the same country.
