Later in 1883, Steinitz took second place in the extremely strong London 1883 chess tournament behind Zukertort, who made a brilliant start, faded at the end but finished three points ahead. Steinitz finished 2½ points ahead of the third-placed competitor, Blackburne. Zukertort's victory again led some commentators to suggest that Zukertort should be regarded as the world chess champion, while others said the issue could only be resolved by a match between Steinitz and Zukertort.
