Stephen Hendry again criticised the condition of the tables after taking revenge over Joe Swail to reach the quarter-finals of the Thailand Open in Bangkok.
Swail had knocked the world champion out of the European Open at the same stage a fortnight ago but Hendry was more concerned with the difficult playing conditions than overcoming the Irishman.
"It's impossible to perform to your best on these tables," said Hendry, who 24 hours earlier had described the conditions as "like playing on an Axminster carpet".
"All I could do was scrap away to the finish," said Hendry, who tackles John Parrott or Dave Roe for a place in the semi-finals.
Steve Davis, the winner of the event four years ago, was beaten 5-2 by Ken Doherty.Reuse content
