- What is the meaning of the 4C bid in these auctions?
-
- Opener Responder
- 1S 2D
- 2S 3H
- 3S 4C
-
- Opener Responder
- 1H 1S
- 3D 3S
- 4C
-
- Opener Responder
- 1H 1S
- 1NT 3D
- 3H 4C
-
- Whatever the meaning, 4C can hardly show a suit. The natural bid
- with a 5-4-4-0 or 4-4-4-1 hand is 3NT, not 4C.
-
- Perhaps 4C is a vague sort of cue bid, accepting partner's suit as
- trump. If so, the bid implies short clubs. Let's make a definite
- rule that the 4C bid promises short clubs, and see if any benefit
- results.
-
- There is a maxim that the bidding of three suits, including a jump,
- promises a singleton or void in the fourth suit. This generally
- accepted rule is a liability with many hands. Marshall Miles gives
- this example: You open 1H with S-K3 H-AKQ76 D-72 C-AKQ4, and the
- bidding goes:
-
- Opener Responder
- 1H 1S
- 3C 3S
- ?
-
- Marshall says that a raise to 4S would promise a singleton or void
- in diamonds, so he would reluctantly bid 4C instead. A better way
- to handle this situation is to say that a 4S bid would deny short
- diamonds, with which opener bids 4D. This would be a non-jump
- splinter, showing something like: S-K76 H-AKQ76 D-4 C-AQ104.
-
- Non-jump splinters are defined as fourth suit bids at the four or
- five level, when partner has bid and rebid just one suit. He may
- have bid notrump somewhere along the way, but his only suit bids
- have been in a single suit. There is just one situation in which
- a non-jump splinter may be made at the three level:
-
- Opener Responder
- 1D 1H
- 3C 3H
- 3S
-
- The 3S bid is ambiguous. Opener could have either of these two
- hands:
-
- 1) S-A32 H-7 D-AKQ32 C-AQJ3
-
- 2) S-7 H-A32 D-AKJ32 C-AQJ3
-
- Opener will clarify her hand on the next round. Responder assumes
- for the moment that opener has short hearts, as in hand 1), and
- bids accordingly. Responder cannot make a non-jump splinter bid at
- the three level, because fourth suit bids by responder at that
- level are Fourth Suit Artificial (q.v.).
-
- More examples:
-
- Opener Responder
- 1S 3H
- 3S 4C
- 4S 5S
-
- Responder denies a singleton or void in diamonds, with which he
- would bid 5D, not 5S.
-
- Opener Responder
- 1S 2C
- 2NT 3D
- 3S 4S
-
- Responder does not have short hearts, which would call for a 4H
- bid.
-
- Opener Responder
- 1S 2H
- 2S 3C
- 3NT 4D
-
- Responder has a singleton or void in diamonds, plus spade support.
- With two diamonds, she would bid 4S.
-
- Opener Responder
- 1H 2C
- 2S 3C
- 5C
-
- Opener has S-AK87 H-AQJ32 D-32 C-K10. In this auction the single-
- ton-showing bid in diamonds would be a standard (i.e., jump)
- splinter bid of 4D.
-
- There is little harm in making the non-jump splinter bid with Ax
- in the splinter suit. If partner has xxx in that suit, he will not
- be disappointed to find one slow loser there instead of one fast
- loser.
-
- The rule that the bidding of three suits, including a jump,
- promises a singleton or void in the fourth suit would still apply
- in other situations:
-
- Opener Responder
- 1H 1S
- 3C 3NT
- 4S
-
- Opener Responder
- 1H 1S
- 3C 3H
- 3S
-
- In these auctions opener promises short diamonds, and a 4D bid
- instead of the spade raise would not show spade support and short
- diamonds. Responder has not bid and rebid just one suit, so the
- necessary conditions for a non-jump splinter are lacking.
