ASKING BIDS OVER PREEMPTS
1. When partner opens 2
to 3
, DBL jumps are asking bids looking for second round control.
Partner responds Special RKCB if he has second round control or better. With no control he returns to his suit.
e.g. 2
- 3
RKCB if Opener has a spade control
- 4
no control - 3NT no keycards
- 4
1 keycard without trump queen - 4
1 keycard with trump queen
2. When partner opens 3
to 4
then a minor suit (without a jump) asks for second round control.
Partner responds Special RKCB if he has second round control or better. With no control he returns to his suit.
A major suit is always natural. Forcing below game, otherwise to play.

If Responder bids anything other than Opener's suit, this is Special RKCB Suit Bid .With void or singleton respond to Ace-ask
From a memory perspective, if you wish to simplify then you might adopt the following: Partner rebids his/her suit with 2 of top 3 honours. Otherwise you can play a "graded" response around the rebid of partner's suit. The more you like your hand the more you bid. This is less restrictive than playing Ogust. 3NT can be retained as top 3 honours in the suit.
SPECIAL RKCB (When Partner Pre-empts or is Known to Be Weak)
When partner opens a preempt, RKCB changes to the following:
- 1st step no keycards
- 2nd step 1 keycard without the trump queen
- 3rd step 1 keycard with the trump queen
- 4th step 2 keycards without the trump queen
- 5th step 2 keycards with the trump queen
Any time partner is known to be < 10 HCP then Special RKCB applies When partner is known to be 0-3 HCP then RKCB asks about suit quality (i.e. steps are no honour, J, Q, QJ, K)
