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.
