RKC Kickback

RKC Kickback.

Kickback variety consisting of bidding color or NT at level 4 directly above the agreed trump.

The alleged trump is:

  • explicitly agreed suit;
  • the suit of the responder, if no suit is explicitly agreed;
  • NT in other cases.

The question is asked at level 4, directly above the agreed trump, but previously none of the partners can show the length of the question suit.
