Kickback RKCB 30/14 (replaces Blackwood)



There are 5 Keycards, the 4 Aces plus the king of proposed trump. RKCB(often referred to as 30/14) is used in three situations, The first is in place of 4NT RKCB and is called Kickback. It uses 4 of the next highest suit or 4NT for Spades. So 4 for Clubs, 4 for Diamonds, 4♠ for Hearts and 4NT for Spades is the Kickback ask. To use Kickback the player must have one keycard. If it isn’t clear what trump is, you should make a forcing bid which announces trump. Barring that bidding 4NT as 30/14 and will use last suit bid/shown as trump. The second place 30/14 is used when 1♣ has been opened and responder has made a simple suit response and opener makes a simple raise of a major suit or bids 2NT over a minor suit. The four sequences are 1♣-1-1♠, 1♣-1♠-2, 1♣-1N-2NT, 1♣-2♣-2NT. The third place 30/14 can occur in later rounds of bidding after a 1♣ opening by opener bidding a suit shown by responder below game. If responder has made a response for flat or balanced hands the suit must be bid below 3NT as sec. 19.7 applies to 4♣/4. Where responder is being asked about it’s 1st bid suit where it may be a 4-card major trump suit and 30/14 is being asked at the 3-level then 3NT is used to show a 4-card major with the higher steps being displaced. After 3NT, 30/14 ask may now bid 4♣ as KC Gerber with the same trump as previous ask, with 4NT being to play.

After 30/14, you can ask for Queen of trump by using the next step above the 30/14 response. Asker can make a cue bid instead if still interested but not sure of a small slam(or even for a grand) to avoid 2 losers in a suit and asks for cue-bidding of Kings and singletons, jumping for singletons(where convenient) and possibly a void with 0 keycards in which case responder will repeat the cue bid. Asker can at any time may bid 1 step above trump(at 4 or 5 level)at any point to declares that partnership has all keycards and Q of trump and asks for cue-bidding.

You must not use the Queen ask for cue-bidding. TAB is still possible by bidding trump suit below game after 30/14, but it is only for length, quality is obtained from 30/14.

Responses are:

<>   <><>   <><>  <><>  <> <>   <><>   <><>  <><>  <> <>   <><>   <><>  <><>  <> <>   <><>   <><>  <><>  <> <>   <><>   <><>  <><>  <> <>   <><>   <><>  <><>  <> <>   <><>   <><>  <><>  <> <>   <><>   <><>  <><>  <> <>   <><>  <>

1st step

0 or 3 keycards

2nd step

1 or 4 keycards

3rd step

2 keycards without Q of trump

4th step

2 keycards with Q of trump

5th step

2 keycards and a void (step is trump suit if trump was the ask)

Jump in suit or

Jump over 5th step

1 keycard and void in named suit

Double jump

3 keycards and void in named suit

Jump in NT

4 keycards and a void (this is close to impossible)

If a jump would take you past 6 of trump then bid 6 of trump

With zero keycards and a void you bid the make normal response and hope to show the void later. If the opener bids game in the major, it is a sign-off, signaling the partnership is off 2 or more keycards or 1 keycard and Q of trump. If after agreeing to a minor if opener bids 3NT, it is a sign-off. So any mention of steps for the 30/14 bidder would not include 3NT over a minor.
