Ilivitsky won a 6-game match against Pachman (1–0 with 5 draws) to qualify as first reserve for the Candidates.

1956 Candidates tournament
The 1956 Candidates tournament was held in Amsterdam in the Netherlands in April and May. As the loser of the last championship match, Smyslov was seeded directly into the tournament and joined by the top nine from the Interzonal. Smyslov won, once again becoming the challenger in the 1957 championship match.

With two rounds remaining, the leaders were Smyslov 10, Keres 9½, Geller 9. In the penultimate round, Keres lost in a winning position against Filip, while Smyslov and Geller drew their games, giving Smyslov a full point lead. Smyslov also won his final game, against Pilnik, to ensure victory.
