I would open south at 3
♦, showing a preempt in
♥ or a strong two suiter (four losers or less) with
♦'s and without
♥'s (MisIry Transfer convention). The first big decision is what to bid with north's hand. If your vulnerable preempts can not be as bad as AJT-long then you bid 3
♥ comfortable in the knowledge that your partner will now bid again with his strong two suiter without hearts. If you can have vul preempts headed by AJT, you must bid 4
♥ with this hand. I would respond 4
♥ with north. But first, lets start with the assumption that partner needs better hearts for vulnerable 3
♥ preempt, the bidding would be:
3
♦ - 3
♥
3
♠ - 3NT
Pass
Here, 3
♠ shows 4 losers and diamond/spade two suiter. One rule of these two suiters is that they are 5-5 or better, so two kings in responders hand is only worth one cover card AT MOST (partner could be 6511 and neither king useful). So responders hand lacks fit, and has only two possible covers. End auction, as there are two likely losers or more on the hand.
Now lets assume partner can preempt vulnerable on just about anything (second seat vul preempts have to be sounder, so opposite a second seat 3D, bidding would go as above).
3
♦ - 4
♥
4
♠ - 4NT
5
♦ - 5
♠
Pass
Here responder has a small problem, because unlike the first auction, partner can now have 3 or 4 losers. If only 3 losers, responder could have two working cards, and slam might have some outside possibilities. So responder has two choices. He can pass, which will be right in the long run anytime partner has four losers. However, if partner has three losers, slam is still very possible. For instance if partner has two clubs and only three losers, north has sufficient covers to make six spades a good shot, or if partner has two hearts and one club, the same will be true.
Imagine, if you would hands where opener had 3 losers and responders off suit covers are worth two covers. They would have a spade suit with maximum one of the AKQ missing with solid diamonds (AKQ-fifth) or AKQ-fifth is spades and diamonds missing just one cover. Hands like AKxxx A AKQxx xx for instance (three losers, both clubs working), or AKQxx xx AKQxx x, or AKQxx xxx AKQxx void (each three losers).
Due to this possibility, responder needs to make a slam try over 4
♠. There are several options here. He can raise to 5
♠ looking for six with 3 losers. He can bid 4NT which ALWAYS shows highest side suit king, and in this case implies, but does not promise @C cover. Over 4NT, opener can bid 5@C to discover if @CA is held with four losers, and imply @HK is useful, or that opener has only three losers in this case, and still ask about @CA.
Here, opener has the worse hand he could have for his 4
♠ bid and hearing a 4NT response. First, he has four losers, not three. Second, the heart king is totally useless to him. So over 4NT, he bids 5
♦ as a pass/correct type warning that heart king is no good. Responder corrects to 5
♠.
