For continuing n.r ..keycard(s) with a void here is an hand from another book of G. Barbone (Bridge Allegro pag. 238) : North ♠ - ♥ J 10 4 ♦ 8 7 6 4 3 2 ♣ 7 6 4 2 , South ♠ K J 3 ♥ A K 8 7 6 5 2 ♦ - ♣ A K Q. South (with an unsaid bidding) final contract is 6 ♥ (not vul vs vul): West has ♠ Q 10 8 7 ♥ Q 9 3 ♦ Q J 9 5 ♣ J 3 (..factible but against killing leads of Queen of heart), bye.

I think that part of solution is on distribution of points : when opp are silent we lacking information (it is true that a type of bidding like this one gets a limit to consider that) are going to say points are equally divided or it is 6-4 such as with J in S and A in N yet in N we have ♠ K and ♣ Q but the same points we have if ♣ Q is in N. About shape than it is possible be as already in posts indicated but at this point the problem is where is the Queen ? As i've said we can try to catch ruffing at 3th round in club, but if don't ? When we consider a positional type E2(=with two cards to entry) against Qxxx and Kx in S if S discard spade we can lead little to A and then little to (winner) J but if instead S has three spade and three clubs without Queen ? Now squeeze doesn't work but impasse yes if on last red card in E looking dscarding in S we pitch little spade and reserving Q and after leading J or x to dummy ...(against Kx now) impassing, bye.

Hallo, there is in this hand vary squeeze positions (but this doesn 't mean that all is ok): two positional against South, also an automatic whilest for trump squeeze if squeeze card is in East (en passant i prefer to say so instead lho or rho to avoid mistakes) it needs to have in dummy two entry (one for card to ruff and the other to rescute when winner). But in club ruffing in third round we can catch Queen 3th in every side.. Than having N already show A and missing 10 points.. it are divided ?

It serves to give this information of void when keycards are minus of three not togheter as in convention at 6 level but on lower(=safety) level (5). After the partner bidding the RKCB decide in base of his/her cards if is the case to continue for grand (having more space is prossible perhaps to declare yet sure that all condition for this be available). Infact RKCB investigate for controlls in a way more deeply respect the past but heavy of shape is sometimes determinant to have a better result.. I remember (i have forgot whom) that a member of Blue Team said "I prefer bid a little slam and to make an ultherior trick that bid a grand and to lose a trick (because a squeeze don't work).

To make a tabel is not a problem but it seem to me also reading my precedent post that all cases are described : only at 6 level we have position of void (i.e. 6 ♦ meaning is three keycards and void in diamond, starting 5NT as in convention (2 keycards plus a void) until NT with differred(=delayed) bidding on answer that ask for queen the position of void is indeterminate such as 4NT ? if partner bids 5♣ = 1 keycards, 5♦ = ? for queen and if partner bids 5NT = 1keycards plus a void and queen of heart(=trump), This NT is the delayed or differred bidding (on subsequent round). When you not have the queen for don't miss the information of void we bid 5♥that now meaning 2 keycards without the queen or 1 keycards plus a void without the queen. The same for indication of a void without ace starting with 5♦ = 0 keycards with or without queen but i can have a void : in this case bidding usually ending i trump on leve but in (rare) case go on always the indication of void is on the answer of 5NT = a void plus queen, bye.

Let's consider the case of 1A with a void(=v) and deviding if a) we have the Queen, b) we have not the Queen in trump suit. In this circumstance in both cases you initially signal Ace : let's suppose heart is trump suit and over 4NT we than bid 5 ♣, if partner ask for Q with 5♦ we answer as usually and to comunicate a void bid 5NT making a delayed information. In case b) considering that void is however a control of first round like an Ace and we insert this one in 5♥ meaning 2A or 1A + void without Q (there is an example in my post n. 25). For logical extension and also compatibility with this convention (there is another way to indicate if there is or not the Queen in trump suit with subsequent ask in two step but is another Blackwood variation) you insert a void and 0 Ace in 5♦ (with RKCB 1430 but in case trump suit is a minor and expecially club is suggest RKCB0314) answering in the same way over (eventual) 5♠ (skipping 5♥ that means sign off).Than we have that: with 3 keycards(=k) + v directly 6, 2 k + v directly 5NT, 1 k + v (over 5♣) delayed NT, 0 k + v (over 5♦) delayed NT. I hope this variation of RKCB convention be usefull almost to contein case you get out of level with your contract, bye.

Thanks for dialogue, i' ll answer (before explaing my idea about how we shall show a void with a keycard) to a "usefull" void: my thinking is that this one must be always show and RKCB bidder (we must use 1340 for it gaining space almost actually) valutes(=know) if void is helping..

I only have starting to say: for instance when you have 2 keycards and a void bid 5 NT and we can rule (as i have said) differently also 1 keycard and a void separately from 3 keycards and a void (but in this way we take a difference from convention).

I think that this argoument must be discuss more deeply RKCB1430 being substitute(=up-to-date) of classical Blackwood and comprending, fourthemore, possibility to signal void. For this aim i have found in my books an hand played from so called by Pierre Jais "coming-man" n.1 of french bridge (at that time).....North ♠ - ♥ 10 2 ♦ A K Q 6 4 3 ♣ K Q 9 8 5 South ♠ Q 9 8 7 4 ♥ A K Q J 9 6 3 ♦ - ♣ 3 The real bidding was :S 1♥ W 1♠ N 2♦ E 3♣ S 3♥ W p N 5 ♥ E p S 6♥. Now let's suppose that N instead 5♥ bids 4♥ and S will continue with 4NT ... what to get 6♥ ? (Opening leads spade A,ruff 2, diamond 2, spade 4.). I don't want you try to resolve the play but you consider subsequent bidding of 4NT, bye.

This type of problem ( a void in the hand of partner) when 4NT arises could be resolveble reserving 6 level only when your partnership has 3 keycards and a void (this one is already ruled) bidding the other cases in a different way. Althoug because we are talking about let me thinking we are trying to estabilish a variant to official convention (or to insert anything), bye.

I have read the long post of Mbodell about RKCB and must say that seem to me to find same rule of Asking Bid when there is ask for Queen (and relative positive/negative answere) and cue bids for King. It easy for me apply because i know this strong convention - properly a system for controlls - having used this years ago when i played with my partners. Nowadays is not much used probably because its many answers (about 15) to make difficult to memorize (but i have found a way to simply..) and competition with cue bids (more easy instead) could have countributed. Pay attention don't have same pattern and also to have a clear and defined exposition of RKCB because complexity and difference doesn't help, bye.

The information of two Queens being way to reach 7♣ (togheter longness in spade) there will be enter 6 level either 6 cards RKCB (www.bridgeguys.com/Conventions/6AceRKCB.html) or as i have said using RKCB0-3 1-4. Infact 6 cards RKCB occurs when is descovered a double fit in expicit way (two suit reciprocally raised) or implicitally when from bidding cannot be exclude a raise in another suit.

I want to remember that 4NT (roll) Blackwood over 2♣ - 2♦ (=minus of 3 Kings or an Ace and KQ) is ruled so: with 0 A and 0 K= 5 clubs, 1 K = 5 diamonds, 2 K = 5 hearts, 1 A = 5 spades, 1 A and 1 Q= 5 NT. Eventually (between expert players) ultherior roll askings are done for knowing number of queens..(From "Il libro completo del bridge di gara" di Guido Barbone pag. 515). In topic "Problem initiating RKCB" is said that in this case (2♣ -..) 4NT is not RKCB than (probably) we must bid as i have indicated. But now my question is: there is incompatibility in this case to apply 6 cards RKCB or we can avoid (and how ?) it ? If let's consider that Queen of spade is pair in 6 cards RKCB to a King and 5 ♥ ask Queen 5 ♠ should indicate Queen of clubs + Queen of spade and so we have what we looking for.

I know classical Blackwood is ruled differently in case 2♣ opening and 2♦ answer by partner (such as 4NT? - 5NT means A + Q) Is it so also for RKCB and in this case what is scale ?

It seems to me that here vary point of views makes bidding free ( or more modern ) but rules are a warrant for success than why don't follow them ?

The problem is this: to try bidding for 7♣ naturally without to think initially to get there. After raise we know that probably we can go up 4♠ because for a (possible) little slam in spade we can support a loser (in heart ?). Than RKCB reveils 1Ace and now with 4 Aces we can consider "possibility" of grand slam but if let's see the hand exchanging 8♦ with Q or J ♣ we have same points for 2♠ but slam is not so easy if we don't reveil double fit in club (with 4 as cards lie..) and how or why we must do it ?

(I also don't know if ........--wow) With this occasion (i don't know if you refer to my post n. 20) i want to say that, obviously, are not in the hand 12 points that makes correct bidding (in that case for delayed raise in spade) but 9 points as you see (correction) in post 21, bye.

East has an hand valutated in 19 points (and with 3 Aces and 2 Kings i wonder myself if doesn't think to slam) After 1♠ West 2♣ tells double fit and 12 (almost) points and all is easy.

I don't undestand 3NT (10xxx ??) If South pass (and also opp) we'll be on the same point with a lot of infornation about club and spade and force on second round

The hand of South doesn't allow 2♠ bidding (underopening, one suit 6/+) and also seeing (=double dummy) to get slam needs 2-1spade and club honors divided between opp 3-4.. Too many conditions to realize.(Lovera)

To be ultheriorly clear : South with 8(-10) points and a 5-4 sh. must bid its second suit (here spade) enter level 2 but not 3, North with its (forcing) jump sure 9 tricks and needs only a trick for manche whilest South bidding then spade ask for control of heart. And than why North bids 4NT? Probably hopes more of 8 points for diamond slam, or go hunting or simply overbidding.
