As a result of all his showmanship poker became respectable in America, more or less. It was taken out of the dens and into glittering rooms with thick carpets. From a relic of the old outlaw West, like cowboys themselves, it became corporate and modern: the World Series of 2006 had more than 8,000 players. Slim played with Richard Nixon, Lyndon Johnson, Mickey Rooney and Larry Flynt, whom he ate up like a ginger cake for $1.7m in one sitting. He appeared 11 times on the Johnny Carson show. He could never quite believe that he, who had made a life's career out of hustling and gambling and illegal activity, had addressed the Senate and was a personal friend of George Bush senior.
