I missed the second time Daz caught by the rule, it wasn't streamed online. But it sure put the Chinese players in advantage since they merely need to say it in Chinese. While foreigners were resorting to either pointing with cue or ,in Ken Doherty's case, slapping pockets angrily with his hand.
I know for sure that the refs reviewed video tapes of the 1st round game that Daz lost to the rule and they couldn't tell which pocket he called.
If the hill-hill game in the 2nd round, Daz only said "cornet pocket" in English, I think it would be missed in the tape too. Since the refs don't speak much English.
