Roman Key Card Blackwood

Roman Key Card Blackwood (Key Card, RKC, RKCB, 0314, 1430) is a variation of the Blackwood convention. It is used when the partnership has agreed to a trump suit and is interested in slam. A 4NT bid asks partner how many "key cards" he holds. A key card is any ace or the trump suit king.

Reverse Bids

In bridge, a reverse is a type of bid by opener that shows extra strength. Specifically, it occurs when opener is unbalanced with 16+ points  and has received a 1 response from partner to their opening bid.

THE RULE OF TWENTY

Open the bidding when your total points added to the number of cards in your two longest suits equal twenty

The advantages of this convention are that it enables you to locate both 5 – 3 and 4 – 4 major suit fits AND keep the strong hand concealed.

 3C  =   “Have you got a 5 card major?”

Opener’s replies:

3D = No, but I have got at least one 4 card major

3H = Yes, I have 5 hearts

3S = Yes, I have 5 spades

3NT = No, and I have no 4 card major either

Responder’s rebids after 2NT – 3C – 3D:

3H = I have 4 SPADES* (opener chooses 3NT or 4S)

3S = I have
