Vlastimil Hort

Vlastimil Hort (12 January 1944 – 12 May 2025) was a Czech and German chess grandmaster. During the 1960s and 1970s he was one of the world's strongest players and reached the 1977–78 Candidates Tournament for the World Chess Championship, but never qualified for a competition for the actual title.

Hort was a citizen of Czechoslovakia for the first part of his chess career. He achieved the Grandmaster title in 1965. He won a number of major international tournaments (Hastings 1967–68, Skopje 1969, etc.) and national championships (1970, 1971, 1972, 1975, and 1977). He gained recognition as one of the strongest non-Soviet players in the world, which led to him being a representative of the "World" team in the great "USSR vs. Rest of the World" match of 1970, where he occupied fourth board and had an undefeated +1 score against the Soviet Grandmaster Lev Polugaevsky—in some respects his greatest result. He defected to the West in 1985, moving to West Germany and winning the national championship of his new homeland in 1987, 1989, and 1991.

Hort participated in a number of Zonal and Interzonal qualifying tournaments to select a challenger for the world title, generally with good results but without reaching the final stages of the Candidates process.

The 1967 Interzonal tournament at Sousse included among its participants both Hort and the great but volatile Bobby Fischer. While leading the tournament, Fischer was involved in a dispute with the tournament organizers over the playing schedule; this resulted in his forfeiting a game with the Soviet player Aivars Gipslis. While accounts of subsequent events differ, it is clear that Fischer was persuaded to resume play, but then did not appear for his game with Hort, who was awarded a victory by forfeit. Negotiations with the organizers went downhill from this point, and Fischer withdrew from the tournament to begin his penultimate estrangement from grandmaster chess. Hort went on to finish the Interzonal in a tie for sixth place with Samuel Reshevsky and Leonid Stein, but did not advance to the Candidates matches, Reshevsky becoming the successful Candidate following a three-way tie-breaking match.

He reached the stage of the Candidates matches of 1977–78 but was eliminated in the first round, in a close match versus the former world champion Boris Spassky.

Hort's long-standing reputation as one of the great sportsmen of chess was enhanced by an event during this match. During the latter stages of the competition, Spassky fell ill and was unable to play. During Candidates matches, each player was allotted a fixed number of rest days to accommodate such situations, but Spassky exhausted his entire allocation of time-outs yet was still unable to compete. At this point Hort could have claimed the match won by forfeit; however, he offered Spassky one of his own time-outs so that the ex-champion could complete his recovery. Spassky did so and went on to win the match by the narrowest possible margin, eliminating Hort from that Candidates cycle.

In the penultimate game of the match Hort had established a clearly winning position, but forgot about the clock, and sat thinking until his time elapsed, handing the win to Spassky. With a draw in the next and final game, Spassky won the match. On the following day Hort gave what was then a world-record simultaneous exhibition in which he took on over 600 opponents. He explained that he gave the exhibition in order to get the loss against Spassky out of his head.

Hort played for Czechoslovakia in the Chess Olympiads of 1960, 1962, 1964, 1966, 1968, 1970, 1972, 1974, 1980, 1982, 1984, and for Germany in 1988, 1990, 1992.
