Steve Davis and John Parrott.
At this stage last year there were wins for Stephen Hendry , Ken Doherty , Peter Ebdon , Mark Williams , John Higgins , Ronnie O'Sullivan and Drew Henry- but the shock of the round was Robert Milkins 's victory over Matthew Stevens in a nail-biting clash that ended 9-8. The Englishman's glee proved short-lived, however, when he crashed out 9-4 in the quarter-final to world champion Peter Ebdon. (S)

Few moments in history have stunned the world more than John F Kennedy 's assassination in Dallas 40 years ago.
The latest in the series recalling earth-shattering historical events is a minute-by-minute reconstruction of the shooting and its immediate aftermath. Contributors include the family standing closest to JFK when the bullet struck, the surgeon who tried saving his life and his assistant press secretary -the man who had to tell America that its young president, arguably the most popular ever, had been killed. Director David Bartlett ; Executive producer Chris Kelly (S) The birth of an icon: page 22

No one knew how much Andy Warhol was worth when the iconic artist died in 1987, and a canny lawyer grabbed his 15 minutes of fame by immediately claiming two per cent of his estate - only to be taken to court in a trial that gripped New York. Warhol's bequest was to establish a foundation for the visual arts, but it's debatable whether his final legacy has been fulfilled as he would have wished.
