Variable Key Card Blackwood

Author: Ken Rexford

Beyond Roman Key Card Blackwood
Easley Blackwood introduced and developed the Blackwood Convention. Eddie Kantar then expanded the Blue Team's Roman Blackwood into the Roman Key Card Blackwood that has dominated expert circles for the past half century. Variable Key Card Blackwood may be the next logical step. VKCB allows partnerships to address many problems that neither Blackwood nor Roman Key Card Blackwood solves, while keeping the auction low enough to avoid bad slams. And, better yet, it is relatively easy to use.
Suppose you have enough power for slam but only the J732 in trumps, in support of partner's five-card suit. You also know that partner has only one of the top three honors. If the honor is the ace, the slam seems good. If it is the king, the slam is not so good. Using VKCB, partner can tell you which honor he has. What about holding 8732? Now you need partner specifically to have the ace and the jack. VKCB has a solution for that problem as well. In fact, you might also find out about a particular side king, all before committing to a slam and without any cuebidding. VKCB solves your problem without going past the safety of the five-level.
