considered as the traditional rapid chess championship, and it often received world championship billing in the absence of an annual FIDE-recognized championship. In its last two years, the 2009 Grenkeleasing World Rapid Chess Championship in Mainz was won by Levon Aronian, and the 2010 Open GRENKE Rapid World Championship in Mainz was won by Gata Kamsky. The Association of Chess Professionals (ACP) also held a World Rapid Cup in some of these years, and the annual Amber chess tournament (1992 to 2011) also had a rapid segment. There was also occasionally a Eurotel Trophy or Intel Grand Prix event, each of which would be of high stature. World Blitz championships before 2012 The first unofficial Speed Chess Championship of the World (or World Blitz Championship) was held in Herceg Novi on 8 April 1970. This was shortly after the first USSR versus the rest of the world match (in Belgrade), in which ten of these players also competed. Eleven Grandmasters and one International Master played a double round-robin tournament. Bobby Fischer won first place, with a score of 19 points out of a possible 22. Fischer scored seventeen wins, four draws, and one loss (to Viktor Korchnoi). Mikhail Tal was a distant second, 4½ points behind. Fischer won both games against each of Tal, Tigran Petrosian, and Vasily Smyslov; all of them were past World Champions. By 1971, the Russian and Moscow five-minute championships had been going several years, with Tal, Bronstein, and Petrosian all having success. That year, Fischer played in a blitz tournament organised by the Manhattan Chess Club, and scored 21½/22. There were also strong tournaments in Bugojno (in 1978), which was won by Karpov; and Nikšić (in 1983), which was won by Kasparov. In 1987, the S.W.I.F.T. super-tournament was held in Brussels, Belgium; first prize was shared by Garry Kasparov and Ljubomir Ljubojević. The first FIDE-sponsored World Blitz Championship was won by Mikhail Tal in 1988. In 1992, FIDE held the Women's World Rapid and Blitz Championship in Budapest, Hungary. Both Rapid and Blitz Championships were won by Susan Polgar. In 2000, Anand won the Plus GSM World Blitz Chess Cup, which has since been referred to as a world championship, albeit inconsistently. The second FIDE-recognized World Blitz Championship was won by Alexander Grischuk in 2006 in Rishon Lezion, Israel; the third World Blitz Championship was won by Vassily Ivanchuk in 2007.
