Many bids are forcing or invitational. Many others are meant as "this is the end of the auction," but the partner bids again. This can happen on an auction such as:
| West | North | East | South |
|---|---|---|---|
1 | Pass | 1 | Pass |
| 3NT | Pass | ?? |
The 3NT bidder is showing something like:
Q 
KQ AKQ7654 
K32.
He shows good long diamonds, stoppers, and a desire to play in 3NT. Must East Pass? No. What if East has a big hand himself? Maybe East has:
AKJ7 A32 J105 A76.
Certainly, knowing what he knows about opener's hand he should bid again (probably 7NT).
In this quiz, you will see 4 auctions for each problem. Your job is to identify the one (there will be only one) which is 100% "end of auction." In other words, it is inconceivable that the partner of that "end of auction" bid can ever bid again.
Which one of these "final bids" really has to be the final bid. In other words, it is inconceivable that the partner of that final shown bid can take another call other than pass.

3 3Answer: 2In #1, Opener can take a preference back to spades. In #2, Opener has shown 12-14 balanced and Responder has placed the contract in 2S (Opener must pass). In #3, Opener can have a nice hand with extras, maybe 3=1=5=4 and bid 3S. In #4, Opener's jumpshift is GF, so responder's 3S can't be passed.
Your result so far:Which one of these "final bids" really has to be the final bid. In other words, it is inconceivable that the partner of that final shown bid can take another call other than pass.

2NT 3NTAnswer: 4In #1 and 2, Opener's second bid is invitational. In #3, Opener shows a big hand, but who is to say Responder doesn't also have a big hand with intention to head towards slam? In #4, opener has limited his hand and responder has placed the contract. There is no possible hand opener can have to bid again.

4Answer: 4In #1, Responder can have anything and surely might bid again. In #2, 2
is not forcing, but the auction can continue if opener has extras. In #3, opener showed a big hand, but Responder might also have a big hand and certainly can bid again. In #4, the 4 bid has to end the auction; there is no hand responder can have to warrant further action.Your result so far:Which one of these "final bids" really has to be the final bid.

3 3NTAnswer: 1In #1, Opener should not bid again. 3
is an absolute signoff (just furthering the preempt). In #2, Responder's 2NT asked for further description. Opener showed a minimum, but Responder could be bidding again anyway. In #3, 2 is forcing (playing standard). The player who bid 2 could have a huge hand and might bid again. In #4, Responder's sequence offers a choice between 3NT and 4.Your result so far:Which one of these "final bids" really has to be the final bid.

3Answer: 2In #1,Opener shows a big hand and Responder is unlimited and could bid again. In #2, Responder's 3NT after a preempt is a complete signoff (if he wanted to offer a choice, he needs to bis 2NT first). In #3, Responder's sequence shows game interest; Opener could bid again. Opener's 3
in #4 is invitational with at least 5-5 in the red suits.Your result so far:Which one of these "final bids" really has to be the final bid. In other words, it is inconceivable that the partner of that final shown bid can take another call other than pass.

For option #3, responder is the one showing a minimum, but opener could have a strong hand for his 2NT bid since this is a game forcing auction. In #4, opener knows how many keycards his side has, and can take charge if they have 4 of the 5 keycards. In #2, however, responder has shown a number of keycards and opener said, "we don't belong in slam". Do not bid again.
