- THE MILLER CONVENTION
-
-
- Opener Responder
- 1NT 5C
-
- Opener Responder
- 1S 2H
- 3NT 5C
-
- These and other "out-of-the-blue" jumps to 5C over a notrump bid
- are the Miller Convention, forcing to slam and inquiring about
- strength. The Miller Convention does not apply if clubs have been
- bid naturally (by anybody) during the preceding auction:
-
- Opener Responder
- 1C 1H
- 2NT 5C is natural, not Miller
-
- Miller must be a jump bid:
-
- Opener Responder
- 1NT 4NT
- 5C is part of the Boland convention (q.v.)
-
- After a Miller 5C bid, partner shows his exact strength:
-
- Opener Responder
- 1NT 5C
- 5D - minimum hand
- 5H - middling hand
- 5S - maximum hand
-
- Responder may be able to place the contract on the basis of the
- response. Perhaps a 5S response gives a total of 35 HCP for the
- two hands, so responder bids 6NT instead of searching for a suit
- contract. If responder bids 5NT or any suit, she is looking for a
- suit contract. Opener bids his cheapest ranking biddable suit
- (Q10xx or better). Until a fit is found, each player shows biddable
- suits in "up-the-line" fashion. If no fit is uncovered, the
- partnership will play in 6NT.
-
- The Miller bidder may also be looking for a grand slam. If she
- finds enough strength for seven, she must not make a non-forcing
- bid below that level:
-
- Opener Responder
- 2NT 5C
- 5S 5NT
- 6C 7D
-
- Responder sees enough points for 7NT, but is willing to play in a
- safer suit contract if a good fit is available. The 5NT bid was
- forcing, but now she must bid seven of something because a six-
- level bid could be passed. Opener can pass 7D with good four-card
- diamond support, without which he shows a biddable major suit if
- he has one. Otherwise, he bids 7NT.
-
- If a player bypasses a suit that was bid prior to the Miller bid,
- he shows that the suit was "unbiddable":
-
- Opener Responder
- 1D 1H
- 2NT 5C - Miller
- 5D 5NT
- 6S
-
- The 5D bid shows a minimum hand. Opener has a biddable spade suit,
- but his diamonds were weaker than Q10xx, or he would have bid 6D
- over 5NT. Opener's hand: S-AQ32 H-Q3 D-Q762 C-AKQ
-
- If the Miller bidder names a suit previously bid by partner, she
- must have a biddable holding in the suit:
-
- Opener Responder
- 1D 1S
- 2NT 5C
- 5H 6D shows biddable diamonds
-
- With only Qxxx or less in diamonds, responder would bid 5NT over
- 5H, giving opener a chance to show that diamonds are biddable.
-
- The reason for requiring biddable suits in these auctions is to
- reduce the likelihood of playing a trump suit such as A432 opposite
- Q765 when notrump is likely to produce more tricks.
