There's a huge crowd in watching Judd Trump v Stephen Lee and they have so far been rewarded with the best snooker of the morning from Trump, whose 137 total clearance in the third frame is the highest break of the World Championship up to now.
He leads Lee 3-1 and will take some stopping, not least because he's the only player out there who doesn't seem nervous.
Anthony Hamilton and Ricky Walden are missing everything between them.
Ditto Fergal O'Brien and Jamie Burnett, although O'Brien is adept at scrapping it out when his form isn't quite there.
Mark Williams has just gone 3-2 up on Tom Ford, who left him in after twice being called for a miss when he could see reds directly.
Williams missed frame ball red with the rest but Ford could not take advantage.
By the way, Williams has never qualified for the Crucible. The first time he played there in 1997 he was already a member of the top 16.
Liang Wenbo has been tied up in knots by Dave Harold but has just edged ahead 3-2 early on in what could be a very long day.
