Your opinion Quizmonkey does not make it fact. Look up hole in a thesaurus and it will show vent. The clue is quite valid and it does not become you to call a clue very sloppy when you have simply been caught in an error and are trying to justify that error.
Oh look another who is getting all huffy and stating as fact what is only an opinion. Do you ever say, in my opinion, cruciverbali? Have you perchance contacted the Telegraph to voice your displeasure? Some people!
Waugh - from what standpoint are you giving your 'opinion'? Do you know anything about crosswords, at all? Are you an expert on clueing? From your ill-informed posts above, clearly not. You're criticising people who DO know what they're talking about - yes, it's only my opinion (hey! that's what boards are about) but it's the opinion of myself as a professional cryptic crossword compiler. Yourself?
Who gives a flying fig WHAT you think? Do you think that just because it is your opinion that a clue is a bad one that it helps anybody? The answer is clearly ventilate and so why not just say so? Do you really have the nerve to think that just because you think the clue is bad that anybody whatsoever gains from your opinion?
