Thanks for your replies. I had AKQJx Kx Kxx xxx and bid 3S. Since X and 4C would be super accept for hearts, I didn't think 3S can be construed as heart support but that doesn't seem to be the case. Post this bidding, I figured my hand has really improved. My reasons for bidding 3S were to introduce the suit for lead directing purposes if we defend clubs and introduce spades as a possible strain. 4S might make opposite xxx QJxxx QJxx x for example. Will the fora pass with the hand I had or will you open something else in the first place?
