Suppose you have something like AQJxxx of clubs (and no other values). If it were any other suit than clubs, I'd open with a with a "weak two" bid.
But two clubs is the STRONG two bid. Meaning that if I wanted a "weak" two bid, I'd have to go to THREE clubs. With such a strong honor holding, is it ok to do so with only six clubs, on the theory that your suit is actually stronger than a seven card suit such as QTxxxxx? (If your partner has nothing, you figure to win five tricks, going down four, but your opponents can make a small slam.)
Would you do this with another suit besides clubs, where you could bid a weak two? And how would vulnerability affect your answer.
