Drago was unimpressed with Ebdon's toilet habits

It was a classic clash of personalities as the fiery and impulsive Tony Drago took on the methodical and measured Peter Ebdon for a place in the quarter-finals.

And it certainly wasn't a case of opposites attract.

Drago was less than impressed with the defending champion's inability to last more than a couple of frames without needing to visit the toilet.

And Ebdon further frustrated Drago with his lengthy deliberations over each shot, pushing his average shot time up to nearly 30 seconds compared with Drago's 12.

The slow psychological deterioration of a player is one of the gruesomely fascinating aspects of snooker and Drago provided aficionados with a classic of its kind.

Who is snooker's slowest player?

His stare and ironic applause as Ebdon returned from his second toilet break were worth the admission price alone.

And if you ever want to see a visual definition of the term 'paying lip service', have a look at Drago's cursory handshake with his opponent at the end of the session.

And as for conceding a frame with seven reds still left on the table, that's when you know your opponent may have let things get to him.

The post-match press conference on Saturday should make for compulsive viewing.

To lose one chance at a 147 maximum break could be regarded a misfortune, but to miss two looks like carelessness.

Oscar Wilde never actually said that, but he would have done if he had been at The Crucible for John Higgins' game against Sean Storey.

In the space of two sessions Higgins made perfect starts before the breaks fell apart agonisingly short of emulating Ronnie O'Sullivan's stunning clearance.

Third time lucky, perhaps?

As Jimmy White continues to make impressive progress through the tournament, opening up a 5-3 first-session lead over world number seven Stephen Lee, nervous bookies have slashed his odds of winning the tournament from 150-1 to just 25-1.

But knowing Jimmy, he'll have backed himself at decent odds long ago.
