Also, kind of twisted, reliance on the FD card is suspect. In recent match, opponents played a variable weak NT, 10-13 NV, 13-15 Vul or in 4th seat. The FDCC did not accommodate the change, so opps needed to edit as they bid. Needless to say, that did not occur consistently. Fortunately, beaten like a drum in that match, so no hard feelings.
