Name That Convention

I am known to be a non-fan of conventions. KISS (Keep It Simple Sweetheart). However, some of my readers just love conventions. Here is a quiz to test your knowledge


West North East South

4.What convention is being used if West’s 2♣ says nothing about clubs, but promises a limit raise in support of hearts?

West North East South

Stayman Bergen Raises Drury Gerber Other
Drury uses a passed-hand 2♣ response to a major-suit opening  to show 3+ card support and a limit raise.

5.What kind of double is not illustrated in the auction below?

Takeout Negative Responsive Support Dbl & Redbl
Negative double. A Negative Double is made by the responder (East in this auction) after an overcall. There was no overcall and East didn’t double. North’s double was a Takeout Double. South presumably made a Responsive Double. West made a Support Redouble.
