Snooker: John Higgins and Stephen Maguire remain deadlocked in the all-Scottish semi-final of the World Championships in Sheffield.
They had previously shared the opening eight frames and were still level at 6-6 at the mid-session interval in the best-of-33 showdown.
The initial session had been high on quality with two centuries and four other 50 plus breaks and continued in the same vein after a scrappy opening frame lasting 32 minutes.
Maguire eventually won that with the aid of a 31 break after Higgins played a poor safety shot on the final yellow and left it hanging over the middle pocket.
Higgins, the 1998 world champion, has yet to lead in the match but he was quickly back on level terms with a 90 break in frame 10.
His opponent, competing in his first world semi-final, again nosed ahead with a run of 63 in frame 11 proving decisive.
But Higgins responded and, although breaking down on 45, Maguire was unable to capitalise after going in-off with the cue ball after potting a red.
In the other semi-final Shaun Murphy will be looking to take another step towards his second world final in three years after seizing the early advantage against qualifier Mark Selby.
Murphy had been hailed as a comeback king after his inspired recovery from 12-7 down to defeat devastated Matthew Stevens 13-12 in the last eight.
But he seemed determined not to have to confront similar dramas against 23-year-old Selby, the youngest player left in the tournament, after surging into a 5-1 lead.
Four breaks of 50 or more put the Rotherham based player in the ascendancy before Selby won the last two frames of the session to stay in contention. PA
