(b) [8 pts., 9 losers]
(c) [12 pts., 7 losers; 12HCP + 9 length = 21, can open with 2 1/2 or better quick tricks]
(d) ALERT! "At most two cards in opener's suit, with 6 to 14 HCP and at least 3 card support for all other suits." [13 pts., 5 losers]
(e) The suggested defense to the structured 1NT overcall is for responder to double with game values, and bid with somewhat less, constructive, but non-forcing. Here, responder is a passed hand, so a double would be invitational values, with no change in the meaning of a suit bid. Responder's spade suit, with only one honor, is too dangerous to mention.
(f) Advancer is happy to have a 4 card suit to bid.
(g) A 6-card suit, playable opposite a singleton. Note that this is true because opener is rebidding freely, if opener passes, responder would get another chance to bid.
(h) Advancer may have been forced to bid a three card suit, so the raise shows 5 cards, or 4 in a maximum hand.
(i) Responder is willing to compete to 4D; his hand reevaluates to 10 support points, and the confidence level is high because the restrictions on our opening bids guarantee a good playing hand.
(j) AK with an even number of cards in spades.
(k) Normally, the obvious shift would be clubs, the suit that advancer bid. But the obvious shift cannot be a singleton, so it reverts to the heart suit. East does not have the HK or HQ behind dummy's ace, so playes the encouraging S2.
