He said: "It's disappointing when you have to play in conditions like that, in what is supposed to be the second most important ranking tournament after the world championship.

"The World Snooker Association keep telling us how well off they are but they are destroying this tournament.

"When you play in these conditions it puts you in a bad frame of mind straight away.

"If I hadn't produced my best snooker of the match in the last three frames I would have been out.

"I wasn't going to say anything had I lost the match because it would have seemed like sour grapes."

Henry made most of the front running and led 4-1, 5-4, and eventually 7-5 - it was only then that the 32-year-old Scot found his best form.

He restricted Henry to just 36 points in the closing four frames, replying with breaks of 49, 50, 130 and 77 to set up a last 16 clash with Mark Davis.

Tony Drago produced a stirring comeback to deny Fergal O'Brien his place in round three.

Drago, provisionally ranked 35th from a career high of 10, trailed 6-2 after last night's opening session.

He then went 7-4 and 8-5 down before fashioning a superb rearguard action - reeling off four frames in 40 minutes to win 9-8.

O'Brien managed only 29 points as Drago knocked in runs of 78, 72, 49 and 72.

"Usually I'm leading 6-2 and lose 9-8," smiled the Maltese professional.

"The results don't lie. If I'm down to 35 it's because I'm playing bad snooker. But now I'm not looking at the rankings because they put too much pressure on you."

Drago, currently working with coach Derek Hill who guided Ronnie O'Sullivan to the world title last season, now plays Peter Ebdon.

Ebdon, runner-up to Stephen Lee in the LG Cup, had a routine 9-4 victory over Michael Judge.
