Nick,
On this hand following the 4♦ response showing 7 QPs, isn't there a legitimate concern that responder might be Axxxxx x Kxx Kxx? In any case, DCB is fine since we can bail out in 5♠ if it's indeed that hand. Your treatment of 0/4 looks pretty interesting, and I am wondering how it compares with the awm's PCB approach (which uses odd/even).
In a previous thread, DinDip had alluded to facing "marriage problems" with PCB on some hands, and it will be interesting to know more about your specific scheme and how it tackles those hands.
Opposite the minor kings, we'll play 6
♠ from the wrong side. When South has
♣A, North will often lead something else.
Parity DCB has clear merit but we are set in our ways. We very rarely come across a hand where we think another method might be better.
We keep it simple and devote more effort to finding the right game, plus non-relay and competitive auctions.
