74 minutes 8 seconds set in the 2006 final between Peter Ebdon and Graeme Dott. The match between Mark Selby and Graeme Dott saw a controversial decision by referee Alan Chamberlain. Dott was going in-off, but stopped the cue ball with his fist before it dropped into the pocket, believing that the in-off was obvious. Chamberlain called a foul and awarded four points to Selby. Convinced that he now had the cue ball in hand, as would be the norm after an in-off, Selby picked up the ball to place it inside the "D". However, Chamberlain then called a foul on him and awarded four points back to Dott. Chamberlain's reasoning was that since the cue ball had never left the bed of the table, Selby should have played the shot from where the cue ball finished. Both players and even members of the audience disputed Chamberlain's decision, but it remained unchanged. Quarter-finals Hendry made the ninth 147 break of his career in the seventh frame of his match against Shaun Murphy. Hendry equalled Ronnie O'Sullivan's record for most 147s and became the second man to score a Crucible 147 more than once, having done it for the first time in 1995. Neil Robertson beat Stephen Maguire - who had eliminated him in the second round the year before - 13–8. He became only the second player from Australia in 27 years (since Eddie Charlton) to play a semi-final at the Crucible. John Higgins advanced to the semi-finals against Mark Selby by winning his second consecutive match of the tournament in the final frame, again coming from behind before the last frames, this time 11–12. The final frame required two re-racks. Mark Allen and Neil Robertson both reached the first world championship semi-finals of their careers. Semi-finals Both semi-finals featured impressive comebacks from the eventual losers. Allen came back from a 3–13 deficit against Higgins to 12–15 before losing the match 13–17. In a similar manner, Robertson brought a 7–14 deficit back to 14–14 in his match against Murphy, but lost the final three frames. Final Michaela Tabb made history by becoming the first woman to referee a World Snooker Championship final. This was the first final contested by two former world champions since 2003, when Mark Williams defeated Ken Doherty 18–16. After the first session ended all-square at 4–4, John Higgins opened up an 11–5 lead over Shaun Murphy,
