My partner and I have been playing this style of weak two bids for some time. I think I read and article by Sandy Trent and we just started playing it. Then I was flipping thru the Granovetters' book on Bridge Conventions in Depth and there was a whole chapter on Trent Weak Two Bids. We adopted the whole thing. We play MP's using a Barry Crane light opening style of bidding. Trent comes up all the time and a big advantage is you know your partner has at least one defensive trick and are able to make MP light doubles frequently for big scores. For the older type of weak two bid we just open at the 3 level. Works for us. :rolleyes:
