‘The questions range from the pretty gettable red over a pocket, all the way to the full-table black. Whether you’re taking it to the pub with fellow snooker geeks, ruining a family holiday with it, or suddenly blurting out, “In which year…?” to put off your opponent as he lines up a pot at the club – enjoy it.’ Stephen Hendry & Mark Watson
