ROMAN KEYCARD BLACKWOOD (RKB)

by Yvonne Cains

This convention greatly assists your accuracy in slam bidding. RKB is far superior to regular Blackwood as it gives information about the K & Q of trumps.

Points to Remember:

Using RKB 

 The REPLIES would be:

After the first response if partner has not shown the queen the next highest ranking suit (not agreed trump suit)
asks partner if he has the queen. This is called the Queen ASK. The responses are:

You Partner
AQJ72
AKQJ
AKQ
7
8654
98
J53
K863
2C
2S
4NT
5S
2D
3S
5D
Pass

Compare those hands with this

You Partner
AQJ72
AKQJ
AKQ
7
K654
98
J53
9863
2C
2S
4NT
6S
2D
3S
5C
Pass

Note: Although East has the same value in both hands €“
Hand 1: missing 2 KEYCARDS - stay out of slam.
Hand 2: missing 1 KEYCARD - bid slam.

Key Card Gerber 4C is NOT recommended in suit auctions (as it conflicts with splinters and cue bids). However, if you

and partner do not use these conventions by you can use 4C to ask for Aces but you should know from the bidding that you have 33 pts.

For New Players

For Advanced Players

A new suit at the 6 level before or after making a Queen Ask is a grand slam try, asking partner to evaluate his
holding in the suit. If he has no losers in this suit he will bid the grand slam. This is called either a DIRECT ASK or DELAYED ASK.
