Like what? Maybe because opps have not agreed on a defense?

My X first is obviously a minority vote. IMO the hand has the value of 18 points, too strong for a mere 3. The bigger problem is what to bid over pards 3.

Agreed, again there's no free lunch. I think it's a fair price for being able to have more freedom in your preempts. If your memory is better then mine or my partners you might make it dependent upon vulnerability.

Yes, XX first. A bid by RHO is lead-directing??? No, it's preference, pass is for doubler to pick a suit. 3m-(X)-XX-(3M); X = half-stopper, 3N = two top honours, pass = leave it to you, 4m = just kidding.

That's what you get from adding Multi to your arsenal. You allow opps to bid 2 over your 2 preempt.

3m-(X)-4m = I have my own reasons, don't get in the way.
3m-(X)-3N = I have a raise to 4m, you may bid if you have a reason.

I cannot comment on kickback, but IMO ace asking conventions are the most misused conventions in bridge. To a lot of otherwise good players it is the only way to get to a slam. It doesn't make sense to ask for aces, if you do not know that all suits are controlled, unless you only bid slam only with all keycards. Therefore any methods which reduced the ace asking sequences is a winner. In my partnership there is no Gerber. We use Minorwood in defined sequences. The party that bid a control can no longer use RKCB. 4N is D.I. (Declaring we control all suits, Interogating features not already shown). We use Minorwood/RKCB plus Spiral Scan if we can reasonably expect controls in all suits, know that we have the power and slam depends only on a few key cards. Usually only the stronger party has this knowledge. Of course sometimes a situation comes up, where you just want to shoot a slam without giving away too much information, especially if opps preempt, and ask aces on the way, but these are exceptions.

Why Kickback? You ask for aces, if you know that you control all suits. How can you be sure with 8-11? I agree with Gábor in that respect. I do not agree that 4 is a cue. I read the bidding as follows: Opener has , responder has , opener has , responder has no stopper, opener doesn't have stopper either, but extras in , responder doesn't like black suits. Maybe even the FG should no longer be in force. IMO the only positive bids by responder are 4 and 4N as slam tries for .

It IS the last article describing QUC, precisely BECAUSE the previous articles didn't generate comments. Of course I could have stopped after the last article or the one before, but I wanted to finish what I started: an overview of QUC. I am sorry if this takes up to much precious server space.

QUC is not finished, we keep improving as we learn from experience with the system. But then, is any system ever “finished”? As I have written in another thread, improving a homegrown is slow. I presented QUC on Bridgewinners, hoping to get helpfull comments. Finding some who would like to play the system, exchange ideas and help to get more experience would be to much to hope for.

Our complete agreements take up 57 pages (including overcall structure, leads and signalling) in German. I don't have my own homepage, but could make it available by other means. Considering the responses so far, it doesn't pay to translate our system book.

Although I really don't know what you want to tell me with your comment, I felt I owe you a reply.

If openers suit is not solid he has someting on the side and it can only be a round ace. No idea which, but it doesn't matter. I play another because of partners positive, he will overruf dummy and cash his ace for down 1. if openers suit is solid and pard has both aces, he would have played high on the first , I lead a round suit, he cashes his aces and returns a for the setting tricks.

Correct, after comparing my line with the other posts, I saw the possibility of winning if W has Txxx. Plus the additional chance of dropping T before taking finesse.

Because I don't like to open 1 with a genuine 2-suiter. If you give that principle up, you can play 2 as weak.

It's against the idea of the tournament, so I wouldn't use the information. Anyway I prefer to choose my seat based upon vul- non vul ratio. We are more agressive overcallers as our team mates, especially non vul. Also our 1 is artificial, I like to have vul. Opps. Of course it doesn't matter if you play 16 boards agains the same opps.

It seems to me that everybody forgets that you hardly have a chance if trumps are 5-1, let alone 6-0. All calculations should start at 84% (3-3 plus 4-2).

Damn the D lead removing dummy's entry. I still think the best play is to draw trumps, overtaking J with Q. If trumps are 3-3 everything is ok. You play S and cover E's card, W can take but will give you trick 12. If trumps are 4-2 this line doesn't work even if the ten drops, because you have no discard on the 4th round of trumps. You have to discard 2 on the trumps, then finesse in . You win if E has Q or if W has exactly Qxx, if not there is still finesse. If the ten does not drop, you basically have the same play, but you need more luck in the black suits.

System on is always best in undiscussed situations. It may not be the best solution overall, but better then “inventions ATT”. I like Adams t/o and will discuss with my partner.

Why do you bid 2N with only 16-17? Better 1M-1N; 2-2M; pass or 1M-1N; 2-2; 2N and 1M-1N; 2N with 18-19.

Even with Gazilli 2M in the sequence above can be either 3crd to weak for direct 2M (in QUC 5-7) or doubleton (in QUC 7-9) in rare cases even a stiff. Other 3crd raises 1M-1N; 2-3M limit raise unbalanced and 1M-1N; 2-2; 2M-3M limit raise balanced. We open 1M 10-18. BTW, I like the “Secret Suit Raise”.

There is a very good reason for the 4crd limit raise: the 9th trump. It is good praxis to bid 4 with almost any 5-4-3-1.
