TWiB Lesson #582 (7 of 9)
We attempt to determine how many of the 5 Keycards we have, plus we also hope to be able to determine if we have the Queen of the trump suit. When ♠ is the trump suit, then we have plenty of bidding space to communicate, but when lower-ranking suits are the trump suit, using 4NT to ask for Keycards leaves us little room to exchange information without getting the auction too high. To fix this problem, some partnerships use Minorwood for their minor suit Keycard auctions, but this does not solve our problem in the ♥ suit. There is another approach, called Kickback, that tries to solve this problem. Let’s see how this works.
