Quantitative Slam Bidding by Paul Bowyer

This quiz is all about Quantitative Slam bidding. Basically, it's about reaching No-trump slams when your side has 33 points or more. To do this, one of your partnership may well bid 4NT to encourage partner to bid 6NT (or to Pass if he feels like chickening out). The problem is that players often know about the Blackwood convention when 4NT asks for Aces and confusion reigns over whether 4NT is Ace-asking or not. It is simple, really (!) If your side has agreed a trump suit then 4NT is Blackwood. If not (or if you've only bid No-trumps) then it isn't.

Let's see how you get on with these hands...

Here you are responder. What call do you make?

 Your choice:
A: 6NT. Add up your points to partner's and come to a total. Partner has 15-17 so between you the partnership has 33-35 points. This is enough information to have a shot at a No-trump slam. What else do you need to know?

Here you are responder. What call do you make?

 Your choice:
A: 4NT. Add up your points to partner's and come to a total. Partner has 15-17 so between you the partnership has 31-33 points. This might be enough to make a slam and it might not be - it all depends on whether partner has a minimum or a maximum for 1NT. Essentially, 4NT is a buck-passing bid - partner now has to make the decision of whether to Pass or to bid a slam.

 Your choice:
A: 6NT. Add up your points to partner's and come to a total. Partner has 15-17 so between you the partnership has 32-34 points. The good six-card suit should compensate for any slight deficiencies in the point-count. Bidding Clubs is a waste of time.

Here you are responder. What call do you make?

 Your choice:
A: 6NT. Add up your points to partner's and come to a total. Partner has 20-22 so between you the partnership has 33-35 points. There's no point in bidding Clubs (besides, 3 would ask four four-card majors). Go straight to the point.

Here you are responder. What call do you make?

 Your choice:
A: 4NT. Add up your points to partner's and come to a total. Partner has 20-22 so between you the partnership has 32-34 points. These 4.3.3.3 hands can play disappointingly so you shouldn't be too cavalier in the bidding. 4NT is a classic buck-passing bid - let North decide whether he wants to bid a slam or not.

Here you are the opening bidder. What do you do next?

 Your choice:
A: Pass. As quickly as you deem ethical. Do not dream of bidding further. Partner is offering you the chance of bidding a slam if you have a maximum 1NT opener. Here you have an abject minimum - 15 points and a 4.3.3.3 shape. It's a case of "Thanks but no thanks".

Here you are the opening bidder. What do you do next?

 Your choice:
A: 6NT - with the full expectation that you will make it. You have a maximum 17 points and have a nice 4.4.3.2 pattern - which suggests that you may have two separate sources of tricks. Notice that a 5 response (treating 4NT as Blackwood) is fatuous. What, precisely, do you expect partner to do with that information?

Here you are the opening bidder. What do you do next?

 Your choice:
A: 6NT - just about! We are required to bid slam with a maximum and Pass with a minimum - so what do we do with a middle-of the-road hand of 16 points? Well, here we have let the five-card suit sway the decision - it may well provide the crucial extra trick. With a 4.4.3.2 hand we might have Passed, with a 4.3.3.3 hand we certainly would have Passed. Some players have passed the buck with 5NT when presented with this problem. We think that's just responsibility-dodging.

 Your choice:
A: Pass. This is a minimum hand for 2NT with a horrible 4.3.3.3 pattern. Let it go!

Here you are the opening bidder. What do you do next?

 Your choice:
A: 6NT. Some may have thought this hand worth a 2 opening bid - it is close. Having opened 2NT you must accept partner's invitation to the party. If slam doesn't make when we have this massive hand there will be a stewards' enquiry...
