As far as I know, most players who play Multi play that the difference between bidding 4
♣ and bidding 4
♦ is that the former is meant to make responder declarer and the latter is meant to make opener declarer.
Neither of them are meant to establish a force, because 2NT is available for that.
I do not see how any of the comments made so far are disputing the common sense approach - bidding 4
♣ can be an advanced preemptive bid. It is the same situation as when partner opens a weak two and you raise to 4. It can be a strong hand which wants to play game but not slam, and it can also be a weak hand which wants to block the opponents. The same principle applies to this 4
♣ bid - it just means responder wants to play at the 4 level regardless of which major opener holds.
Granted, the 4
♣ bidder will sometimes have a really strong hand, one which, for instance, wants to play 4
♥ if partner has hearts, but which wants to investigate 6
♠ if partner holds spades. But the Multi bidder cannot know that until responder makes a second bid.
If the North-South pair wish to dispute this common sense approach, they must provide some evidence (not proof - wrong term. I stand corrected) that their approach is different than the normal one.
FrancesHinden said:
- The very fact that South passed over 5C is clear evidence that he considered pass to be forcing, and not only that but he expected partner to think it was forcing as well (or else he would not have passed).
This is true. However, "south considered his pass to be forcing and expected partner to think so as well" does not equal "south's pass
was forcing". Players often bid in a certain way while expecting their partner to be on the same wavelength, and it is not so.
A simple example: 1NT-(2
♣)-2
♥-p-p-p. At the end of the board (or, more likely, in the middle of the play), the opponents find out that 2
♥ was intended as a transfer. Is that any indication that the NS agreement is that transfers are on after the interference? Or is it an indication that they have no agreement and it was a misunderstanding?
I think forcing passes are very delicate situations and I also think partnerships should strive to include as many of them in their system notes as possible, exactly because there is no other way to prove your claim that the pass
was indeed forcing.
Ah, no, no. My name is spelt 'Luxury Yacht' but it's pronounced 'Throatwobbler Mangrove'.
