[net.rec.bridge] Conventions : Roman Key Card Blackwood

red@ukma.UUCP (Red Varth) (03/06/85)

I am not as good a bridge player as my regular partner is, but it's my 
opinion that RKCB is much superior to regular Blackwood. In RKCB, 4NT
asks for Aces, just like regular except that the KING of the agreed-on
trump suit counts as an ace also. Therefore there are 5 aces in the deck.

Responses:	5C	0 or 3 aces
		5D	1 or 4 aces
		5H	2 without the trump QUEEN
		5S	2 with the trump queen

This allows you to get some idea of the quality of your trump suit before you
go trotting off to slam. All the outside winners in the world won't do you any
good if you're off the top trumps (lucky splits aside, that is).

The worst problem with this system is deciding what the trump-suit
is. What we decided on was that any major suit bid and raised was the trump 
suit in question. When we have a minor suit fit, we try to look for NT games 
or slams. In the event that we don't have a suit stopped in NT, any minor 
suit bid past 3NT is the key suit. In addition, no artificial bid can be the
trump suit.

Comments anyone? And, partner, since I know you're out there, please don't
get nasty about errors in public, ok?

As a followup to the rules on "what is the key suit?" let me suggest:
1)  If a minor suit has been bid and raised, it is the key suit even if
    you expect to play slam in NT.  It is unlikely that you will find 
    sufficient winners without establishing the minor suit.
2)  If responder jump shifts, then immediately Blackwoods, his suit is the
    assumed key suit, regardless of opener's rebid.  Responder can use this
    technique with a one-suited monster where the K or Q of his suit will be
    important.  
3)  Similiarly, a player who opens a strong or intermediate two-bid and who
    proceeds to Blackwood immediately after naming his suit is asking about
    his own suit.
4)  In most other cases where no suit has obviously been agreed, the last 
    suit bid by the partnership can be assumed.  For this purpose, IGNORE
    ARTIFICIAL BIDS, e.g., Stayman, 2D negative over 2C, cue-bids, etc.
    Also, with any kind of transfer bid, consider the suit INDICATED (e.g.,
    if 4D is used to indicate a strong 4S opener, 4D-P-4NT would ask about
    SPADES, not diamonds. )
