Variable Keycard Blackwood
 | Variable Keycard Blackwood by Ken Rexford List Price: 122 pages. Paperback. Also available as an E-book. Roman Key Card Blackwood has dominated expert circles for the past half century, but it is not flawless. One obvious difficulty is sometimes not knowing whether the partnership is missing two aces or one ace and the trump king. Variable Key Card Blackwood may be the next logical step. VKCB allows partnerships to address many problems that Roman Key Card Blackwood does not solve, while keeping the auction low enough to avoid bad slams. And, better yet, it is relatively easy to use. |
