Unusual vs. Unusual is use when opponents' make an Unusual Notrump (or Michaels Cuebid) overcall showing a two-suited hand:

• double - penalty;

• a three-level bid in partner's suit is constructive (7-10 HPC) and non-forcing;

• a cuebid of the opponents' lower implied suit shows an invitational limit raise of partner's suit;

• a cuebid of the opponents' higher implied suit shows game forcing values, typically showing 5 cards in the unbid suit;

• a bid in a suit which has not yet been bid is competitive without showing game interest.
