For
extra credit, explain the logic behind the answers to problem 6. Hint:
see problem 2.

>For opener's 1NT bid, opener has at least 4 major suit cards. If opener had fewer than 4, opener would have at least 10 cards in the minor suits. With 10 cards in the minors opener must have at least 6 clubs. If opener were 5-5 in the minors opener would open diamonds. Since opener has at least 6 clubs, opener would bid 2 clubs instead of 1NT at openerŐs second bid. So, given opener has at least 4 cards in the majors opener must either be 2-2, 1-3, or 3-1. If opener has 3 hearts opener will always raise 3 hearts. If opener has 3 spades opener would bid 2 spades over responder's 2 heart bid (see problem 2), which gives responder the information needed. If opener bids 2NT, opener must be 2-2 in the majors, allowing responder to bid 4 spades with 6 spades or 4 hearts with 6 hearts.<
