Live coverage as the second UK championship semi-final reaches its climax at York's Barbican Centre.
Having won the last frame of the afternoon last year,
Welshman Mark Williams went on to take the first of the evening session to trail just one frame behind the "Essex Exocet", Ronnie O'Sullivan. But then the world champion replied with three crushing century breaks to secure a 9-6 victory and a place in the final against Ken Doherty.
Coverage is introduced by Hazel Irvine with Steve Davis and John Parrott. Commentary by Clive Everton ,
