Carter moves ahead in scrappy World Championship semi

Ali Carter edged ahead of Stephen Maguire after an underwhelming opening session of their Betfred.com World Championship semi-final.

Both men struggled to find the form which had carried them through to the final four, 32-year-old Carter having knocked out Judd Trump on the way and 31-year-old Maguire having ended the career of Stephen Hendry in the quarter-finals.
