The Power Of Impletion

6th January – Board 10: Game All. Dealer East.
6NT by South is a grand contract of course and it is a sad fact for West that a spade, heart or diamond lead will provide declarer with his twelfth trick immediately. A spade lead gives declarer three tricks in the suit, a heart lead gives declarer four tricks in that suit and a diamond lead gives declarer three tricks in that suit! Only a club lead gives nothing away but with the fortunate position in the spade suit the contract should still make. I see no reason why North shouldn’t look for a major suit fit and because of that I think the auction might go:
West
North
East
South
No
2NT
No
3C
No
3D
No
4NT
No
6NT
End

With no suit having been agreed 4NT is quantitative, asking South to bid 6NT with a maximum, and South would be happy to oblige.

  1. Why not 5-card Stayman after 2NT Dave, with the sequence here 2NT - 3C - 3NT(no 4 or 5 card major) - 4NT - 6NT?

  2. It's just that people play different things over 3C. Some play, as you suggest, that 3NT denies a four or five card major, while some don't play five card Stayman at all. I play that over 3C, 3D denies a five card major but may have a four card major and then responder bids the four card major that he doesn't have!If responder bids 3NT over 3D he is showing two four card majors. If over 3C I bid 3NT that is showing two spades and three hearts, or perhaps, rarely, 2-2 in the majors. That is by the by as the points is that whatever your methods I can see no harm in looking for a major suit fit.
