London 1883 chess tournament
The London 1883 chess tournament was a strong chess tournament among most of the leading players of the day. It was won convincingly by Johannes Zukertort (22 points out of 26) ahead of Wilhelm Steinitz (with 19 points). Remarkably, Zukertort was already assured of victory with three rounds to go, having scored an astonishing 22/23. He then lost his last three games against relatively weak players, probably due to exhaustion. The tournament established Zukertort as rivalling Steinitz to claim to be the best player in the world, and led to the World Chess Championship 1886 match between the two (the first official World Chess Championship match). The event was a double round-robin tournament. Marmaduke Wyvill contributed to organizing the tournament.
