Am I doing something illegal or something requiring an alert from my partner if I were to routinely open 1 of a major suit in 3rd chair under this scenario: (1) say, KQxxx of the bid major and no other high cards; (2) 3 cards in the other major; (3) 3-2 in the minor suits; (4) using a standard base where 1 of a minor shows 3+ in the opened minor suit; and (5) using two-way Drury (so that both 2♣ and 2♦ show raises in the opened major suit)?
Edit: in light of the first comment offered below, perhaps I should be more explicit/more precise in my wording. I would routinely seriously consider opening 1M under the conditions described, where I felt I could handle whatever response my partner makes. Sometimes I would still reject the consideration, dependent upon vulnerability, status of game, how I felt, whatever.
Obviously this question is derived from some of the issues raised in the threads on the Spain-USA match in Poland.
