Quiz 7 original problem:
Solution–
With interference over 1 NT many pairs play a cuebid as asking for a four card major. If that is the case here (ask away from the table) then the 3♦️ bid is comparable to the Stayman bid, i.e. comparable by the same purpose rule. If North/South are playing Lebensohl then the 3♦️ bid is more specific than the withdrawn bid, i.e. comparable by the subset rule. Otherwise the 3♦️ bid is not comparable.
