Sergio Mariotti (born August 10, 1946 in Florence) is an Italian Grandmaster of chess and former national champion. His world rank of all players is 9648, and of active players 5356. His national rank in Italy is 98, and of all active players, 71. His continental rank in Europe is 7261, and of active players, 4205. Mariotti's FIDE titles are Grand Master (1974) and International Master (1969). His standard rating is 2291.
He became the Italian junior champion in 1965 at Turin and in 1969 at San Benedetto, the full Italian Champion. One of his greatest tournament successes followed in 1971, when he finished second at Venice (after Browne but ahead of Hort, Kavalek and Gligorić).
Mariotti represented his country at the Olympiads of 1972, 1974, 1986 and 1988. At the Nice Olympiad of 1974, he scored a double success. A board one score of 73.7% (+12 =4 −3) earned him the individual bronze medal (behind Karpov and Delgado, equal with Torre) also securing his final grandmaster norm. As no Italian before him had achieved the International Grandmaster title, he gained overnight celebrity status when the honour was bestowed on him the same year. Around this time, British Chess Magazine nicknamed him "The Italian Fury", due mainly to his formidable collection of tournament wins, but also for his enterprising, tactical style of play.
He was victorious in many international tournaments, including Naples 1968, La Spezia 1969, Naples 1969, Reggio Emilia 1970, San Benedetto 1970, Bari 1971, and Rovigo 1976. He won the Rilton Cup (Stockholm) in 1976/77 and triumphed at Lugano in 1979.
With regard to world championship qualification attempts, he won at the Caorle zonal of 1975, to qualify for the prestigious Manila Interzonal of 1976, where he finished joint 10th (with Spassky, Uhlmann and Gheorghiu). The result was insufficiently good to advance to the Candidates Matches. At the Praia da Rocha zonal tournament of 1978, he finished fourth, one place away from Interzonal qualification.
His choice of chess opening often revolved around the Sicilian Defence or Ruy Lopez, where he was comfortable with either colour. Occasionally, his fans were treated to old-fashioned, romantic openings such as the Evans Gambit and Albin Counter Gambit and these brought him surprising success.
Mariotti became an advisor for an Italian publisher and worked for the Italian Chess Federation (FSI), where he was President between 1994 and 1996. As a precursor to the Turin Olympiad of 2006, he played a website game against the 'Rest of the World' and won in 48 moves.
