Martin's recommendation for the minimum HCP of the cooperative double by responder is whatever it takes for the partnership to have combined 22 HCP. Thus the minimum opposite a 15-17 1NT is 7 and the minimum opposite a 12-14 1NT is 10, etc. The maximum for the prototypical coop dbl by responder might vary based upon vulnerability. If the opponents are vul and we are not, one might choose to double in order to look for a penalty with a game-going hand, seeking the Holy Grail of +500 to beat our 400+ game; otherwise the prototypical coop dbl would be limited to less-than-game-forcing hands. (The modifier "prototypical" is intentional, because some other hand types must also begin with a double.)<br /><br />The concept of applying a Total Trumps concept to make effective cooperative doubles is not, btw, limited to auctions that begin with 1NT. I am aware of applications where the interference is not an overcall of partner's 1NT opening but is instead an unusual notrump overcall of partner's 1 suit opening bid.<br /><br />Maybe if the opponents get nailed a few times, they will choose to refrain from interfering with our auctions? That would be a nice byproduct!Anonymoushttps://www.blogger.com/profile/09402419741923703786noreply@blogger.com
