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.

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.



Case: 0 or 3 keycards(void possible with 0 keycards)

The asker can make a TAB ask in trump below game (this bumps up a step the Queen ask, can only occur with 2NT ask with Diamonds as trump) and still ask for Queen of trump later.

1st step asks for the trump Q
            Responses: bid trump without Q and no void
                        Bid next step without Q and with a void. Bidding next step asks for void.
Bids 2nd step with the trump Q, but with a void(Can now bid 1 step above trump to ask for
the void suit, NT=ask suit and bids 2 steps above trump to declares that partnership has all keycard and Q of trump and asks for cue-bidding of Kings and singletons, jumping for singletons.)
                        Cue bid a King(up to 2 Kings)  with Q
                        Bid NT with Q and three Kings
                        Jump in trump with Q but no Kings and at least one more trump than bidding indicated
                        Jump in no-trump with Q but no Kings and minimum trump for previous bidding
Cue-bidding possible as is announcing all keycards plus Queen of trump (see above).

Case: 1 or 4 keycards(no void)

The asker can make a TAB ask in trump below game and still ask for Queen of trump later.
1st step asks for the trump Q
            Responses: bid trump with no Q
                        Cue bid a King(up to 2 Kings) with Q
                        Bid NT in NT with Q and three Kings
                        Jump in trump with Q but no Kings and at least one more trump than bidding indicated
                        Jump in no-trump with Q but no Kings and minimum trump for previous bidding
Cue-bidding possible as is announcing all keycards plus Queen of trump (see above).

Case 2 keycards with or without trump Q
The asker can make a TAB ask in trump below game and still ask for Queen of trump later..
Cue-bidding possible as is announcing all keycards plus Queen of trump (see above).

Case: 2 keycards and a void  Note: must have 5 trump if 1st suit bid.
The asker can make a TAB ask in trump below game and still ask for Queen of trump later.
1st step(not trump or 3NT): Asks for the Q of trump. Without Q bid trump, with Q bid the void suit.
2nd step(not trump or 3NT): above trump asks for the void suit(NT=ask suit)
Cue-bidding possible as is announcing all keycards plus Queen of trump (see above).

Case: 1 keycard and void in named suit
Note: must have 5 trump if 1st suit bid.
The asker can make a TAB ask in trump below game and still ask for Queen of trump later..
1st step (not trump) asks for the trump Q
            Responses: bid trump with no Q
                        Cue bid a King with Q
                        Jump in trump with Q but no Kings and minimum trump for previous bidding
                        Jump in no-trump with Q but no Kings and at least one more trump than bidding indicated
Cue-bidding possible as is announcing all keycards plus Queen of trump (see above).

If there is interference use D0P1 upto 5 of trump then use DEPO. Also use R0P1.

Two Suited Overcalls

These methods are suitable for any system, not just Precision.

Basic 2 Suited Overcalls


Have been convinced by Ian Payn (see http://www.ebu.co.uk/publications/EB-web_library/2009/October/debate.pdf )that the cost of losing 3§ as an overcall bid and other difficulties not to use the Questem convention(Ghestem inverted). Instead Michaels and unusual 2NT are the calls.


cue-bid over a minor = both major suits 5-5. 2NT is responders asking bid.

cue-bid over a major = 5 of other major and 5 of an unspecified minor. 2NT is responders asking bid.

2NT = two lowest unbid 5-5. Cue-bid is responder’s asking bid.

1

I strongly believe that these 2 suited bids should be at least 5-5 in length and the difference in length should be at most 1 card. With 5-4, even in the major, simply overcall in your 5 card suit. 6-5, 6-6 or 7-6 are ok. However, with 6-4, 7-5, 7-4, 8-4 or 8-5 again bid your longest suit.

I used to believe that strength should be mini-maxi, either 6-11 or 16+ pts. However, I found whenever I had the strong hand and bid again, my oartner didn’t believe it and we missed slam. Also, Mike Lawrence in his book Overcalls is against a mini-maxi approach. So the strength should be 9+ HCP at IMPs, lower points allowed at matchpoints, but remember if you don't have a chance to play contract opponents will be able to read you cards like there exposed.

Should you have 16+ HCP and you get another chance to bid,

 Balancing cue-bid

From an unpassed hand this shows a strong 2-suiter of unknown suits. Must use unkown suits as 2NT in this case would be 19-21 Balanced.  Responder, bids as follows

            new suit: good  support for this suit
            NT: weak hand wishes to sign-off
            Cue-bid: strong responding hand, slam possible

            Overcall responds as follows:
            To a new suit:   
                        Raise: if that is one of the suits.
                        Jump Cue-bid: no losers in suit, and has this suit.
                        New suit: doesn’t have this suit, has other 2-suits.
                        Cue-bid: does have this suit, slam interest.

            To a NT bid:
                        Bid lowest of a 2 suiter

            To a Cue-bid:
                        Bid lowest of a 2 suiter
                        Jumping with exceptional strength

From a passed hand a cue-bid is modified Michaels, will show the higher two unbid suits,
but weak. Bidding proceeds similar to a direct modified Michaels above

Balancing 2NT


From an unpassed hand shows a strong balanced hand, 19-21 HCP. Systems
ON. From a passed hand this shows a weak 2-suiter of the 2 lowest unbid suits, bidding proceed
as over a direct call.

New Approach to Asking bids using RKCB 30/14


1.1.       RKCB 30/14 as a Asking Bid and Kickback


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 4N RKCB and is called Kickback. It uses 4 of the next highest suit or 4N for Spades. So 4 for Clubs, 4 for Diamonds, 4♠ for Hearts and 4N 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 4N 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 2N over a minor suit. The four sequences are 1♣-1-1♠, 1♣-1♠-2, 1♣-1N-2N, 1♣-2♣-2N. 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. responder has made a response for flat or balanced hands the suit must be bid below 3N 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 then cheapest NT is used to show a 4-card major with the higher steps being displaced. After NT, ask may now bid cheapest ♣ as 30/14 with the same trump as previous ask, with later bidding cheapest NT (at least 3N) being to play. Bidding the major suit is 4-card trump ask with the cheapest bid skipping 3N or 4M is 3014 ask.

After 30/14, if the Queen of trump was not shown, the next ask is for Queen of trump by using the next step above the 30/14 response unless it is NT or trump. Bidding cheapest step denies the Queen, bidding the next step shows the Queen. At any point in the asking process the Asker can, bid NT saying we are off 0 or 1 KC but need extras from responder, 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) or jump to game which says were off 2 KC or 1 KC and trump Queen. Responder should be careful about cue-bidding with 8-10 HCP as an unpassed hand and just repeat trump or NT especially where partnership may be in a 4-3 fit. This is because with just two Aces and no further points, opener could get overly excited.  After asking for Queen of trump next step, skipping NT and trump announces partnership has all the KC and Queen of trump and asks for specific Kings, responder bidding trump denies an outside King, bidding NT shows K of ask suit. 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 3N, it is a sign-off. So any mention of steps for the 30/14 bidder would not include 3N over a minor.

 

Case: 0 or 3 keycards(void possible with 0 keycards)

The asker can make a TAB ask in trump below game (this bumps up a step the Queen ask, can only occur with 2N ask with Diamonds as trump) and still ask for Queen of trump later.

1st step asks for the trump Q

            Responses: bid trump without Q and no void

                        Bid next step without Q and with a void. Bidding next step asks for void.

Bids 2nd step with the trump Q, but with a void(Can now bid 1 step above trump to ask for

the void suit, NT=ask suit and bids 2 steps above trump to declares that partnership has all keycard and Q of trump and asks for cue-bidding of Kings and singletons, jumping for singletons.)

                        Cue bid a King(up to 2 Kings)  with Q

                        Bid NT with Q and three Kings

                        Jump in trump with Q but no Kings and at least one more trump than bidding indicated

                        Jump in no-trump with Q but no Kings and minimum trump for previous bidding

Cue-bidding possible as is announcing all keycards plus Queen of trump (see above).

 

Case: 1 or 4 keycards(no void)

                        Jump in no-trump with Q but no Kings and at least one more trump than bidding indicated

Cue-bidding possible as is announcing all keycards plus Queen of trump (see above).

 

If there is interference use D0P1 below 5 of trump then use DEPO. Also use R0P1.

1NT Direct Overcall


1.1.       1N Direct Overcall


In direct seat 1N shows 16-18 hcp (or good 15 HCP) balanced with a stopper, 15-18 hcp in 4th seat to protect against light 3rd seat openers. 1N by a passed hand shows a 2-suiter in the lower unbid suits, possibly with the lowest suit being longer (at least 4-5 in length).

 

Responses:





For 1N overcalls you’re unlikely to want to play in opener’s suit, so using transfers, a transfer to opponent’s suit is used artificially, usually as Stayman. All 2-level suit bids are transfers, with a transfer to opener’s suit being Stayman and 2♠ being a transfer to ♣ (or to ¨ over 1♣ opening with 2C then being Stayman). Overcaller completes the transfer without 4M and a minimum, bidding 2N without a 4M and a maximum.  With a maximum and a 4-card major overcaller jumps in the major, except over 1♣/1♦ opening. Over a 1♣/1♦ opening overcaller cuebids with a maximum and both 4-card majors.


2N is INV, except over a 1♣ opening where it is Minor Suit Stayman and can be passed out in 3m; bidding a major is a shortage and a game try. As 2N is otherwise engaged 2♣ Stayman over 1♣ opening is also used for balanced invites without a 4-card major.

3♣ shows both minors (except over a 1♣) and is NF. A jump cuebid (except 3♣ which is natural and preemptive) is Minor Suit Stayman. Other 3-level suit bids natural and preemptive.

Gerber is 4♣, 4♦/4♥ are Texas transfers, with a Texas transfer to opener’s suit being minor suit Stayman without slam interest or when responder is going to bid slam but needs a preference.

Opponents double 1N:

Pass – suggested place to play, overcaller may bid 5-card suit, pass or redouble with doubt, then responder can leave 1NXX in or bid 4-card suits up the line till at least a 4-3 fit found, possibly playing in opener’s suit.

Redouble – transfer to ♣ even after a 1♣ opening. If responder next bids 3♣ it is INV.

2♣/2♦/2♥ – transfer to above suit, even if it is opener’s suit. If responder’s next bid is a raise or 2N is INV

2♠ – natural and constructive, overcaller may compete to 3-level with a fit if pushed

2N – both minors, usually weak, but may investigate for game by bidding their short major

3 bids – natural and preemptive, with a jump cuebid having no meaning

3N – to play

Gerber is 4♣, 4♦/4♥ are Texas transfers (with a transfer to opener’s suit being minor suit Stayman usually with no slam interest)

 

If 1N gets doubled in balancing seat then:

Overcaller’s partner redoubles for SOS

Pass to play, other bids natural and non-forcing, including cue-bids

 

Opponents bid again at 2-level:

Doubles are negative, doubling then cuebidding is usually for the minors

2 level suit bids are natural and to play, even a cuebid

Transfer Lebensohl is used for 2N, 3N and 3-level suit bids

3-level cuebids are Stayman with a stopper (double without a stopper)

Gerber is 4♣, 4♦/4♥ are Texas transfers (with a Texas transfer to opener’s suit being minor suit Stayman usually with no slam interest)
