Marco Fu insisted he was no cheat today after his 13-4 demolition of fourth seed Stephen Maguire to reach the 888.com World Championship quarter-finals at Sheffield's Crucible Theatre.
The Hong Kong player was involved in a controversial moment in the final frame of the second session when, on a break of 22, he committed a foul that went unpunished.
Stretching over the table to pot a red with the rest, Fu clearly tapped the blue ball with his cue after the shot but failed to acknowledge it and referee Eirian Williams did not notice.
The break became a frame-winning 47 to give Fu a 12-4 lead and after Maguire had played a bad positional shot to miss the black when the match resumed today, a fine 101 clearance wrapped it up.
