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

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