Rating: 2 boards per segment/round

4 clubs shows a solid major, at least AKQxxxx, with an outside Ace or King 4 diamonds shows a solid major without an outside Ace or King Responder's major-suit bids are pass or correct 4 diamonds by responder is constructive.

Defense:

In direct seat: All Bids Natural Double = T/O of their major (could be as little as 11 HCP) Double then Double when their fit is found = T/O 16+ HCP Pass then double is takeout 4NT = minors

In third seat: All Bids Natural Double of 4 diamonds is lead director. Double of 4 of a major is takeout of opener's major or lead director of other major. (opener will clarify by passing or correcting) Pass then double is takeout 4NT = minors
