3 NT.—10 2 N.T.—3 pass—minus 1
This is the time to make a commonsense bid. The "book" says that you may raise with only seven high-card points if you have a good five-card minor suit. But a six-card suit facing a one-no-trump opening is very likely to produce as many as six tricks. Two no trump gets a bone because there are times when partner will be able to bid three and times when, unluckily, he won't be able to make nine tricks. A two-club or three-club response can only cause confusion and gets no marks here. As for a pass, the minus award speaks for itself.
2 N.T.—10 1[Spade]—5
The fact that you hold a good five-card major is no bar to opening two no trump; in fact the long suit allows you to shade your requirement from a 22-point to a 21-point minimum in high cards. One heart will often lead to a sound result, but if the eventual contract is to be no trump it will probably play better from your side. Furthermore, this hand will often produce nine tricks at no trump facing many a holding (such as [10 of Spades] [x of spades] [x of spades] [Jack of Hearts] [x of Hearts] [Queens of Diamonds] [x of spades] [x of spades] [x of spades] [Queen of Clubs] [x of Clubs] [x of Clubs] [x of Clubs]) that would properly pass a one-heart opening.
3 N.T. 10 2[Heart]—7 4[Heart]—1 (2[Club]—10)
With the lead coming up to this hand the surest game is at three no trump, despite the six-card major. If partner happens to hold a Yarborough and answers a forcing two-heart bid with two no trump, there is some danger that, with the lead coming through you, eight tricks may be the limit of the hand. The award for two clubs—if you use that as a forcing bid with a two-diamond bust response—is conditional; take only seven points if you did not honestly intend to rebid three no trump following a two-diamond response. The award for four hearts goes to commemorate the time my partner passed me out in a forcing two-bid; I don't really expect anyone to earn or deserve it.
