Random minor openings
#21
Posted 2016-April-25, 20:34
On random openings in general, I think it's cleanest if there is a clear key (for example: we open with the weaker minor whenever we have an odd number of 7's in our hand), but again not sure about the legality. I just wanted to bring up the issue of verifiable keys because no one seems to have yet and it's something that has been mentioned on and off here. In practice, however, I assume most opps would just accept "we decide randomly" more happily than "we decide based on the number of 7's in or hand" so maybe all of this is just theoretizing.

I don't think that's the issue. The problem is that 99+% of people who play 1m as "at least three" open the longer minor, and so if no more information is given that is what opponents will assume.

No Ed, the point is that you should explain your agreements in full on request without the opposing pair needing to find the correct supplementary question to obtain full disclosure. Would you be satisfied if I described a canapé 1♥ opening as "could be 4" in an area where the majority system is 5 card majors and a few play Acol or Culbertson? I would hope not; the same applies here.

Because they sometimes like to count out hands? Of course nobody expects you to say
"1C can, if balanced, be 5♣332, 4♣333, 4M333, or 4-4-2-3" but if you have reason to believe that "could be 3" will be interpreted in a certain way by opponents, you should try to explain some special exceptions in which 1C has 3 cards but is unexpected to opponents. For example, 3♣4♦ or 3♣5♦.

I think that your suggestion is sensible, but uses more words than the the entire system summary normally given at the beginning of a round. Unless you are saying that minor-suit openings should be alerted, but that seems wrong.
There is an analogous situation. Some Americans open 1♦ with 4=5 in the minors. I don't know if they alert their 1♦ openings. In this case it truly is canapé, since their intended rebid is the longer suit. Natural logic would dictate that if a side 5-card major on the side is more significant than a 4-card. (In a wholly natural system, ie not one in which a diamond promises an unbalanced hand or otherwise where a 2-card suit can be opened).
In any case, I am of course more interested in our regulations here.

On those occasions when I've played such systems, I announce "could be two, could have longer diamonds". If they want more detail they've been given a prompt.

Would it be acceptable to announce, "could be three, could have longer diamonds"? (Or maybe could have four diamonds, since I would never have five"?

Not required. One might argue that a club rebid should be alerted. I don't think it's required, but I haven't checked the regulation.

Thanks for the input...
(*): Literally "says" as this regulation is not written down anywhere but the TDs know it. The players may learn about it eventually if they happen to play it against a TD...

If you get a blank look, then they play Majors 5, diamonds 4 (or they play Precision the "boring" way if it was 1♦ "could be short"). Otherwise I usually get *something* (of course I remember the person whose partner opened 1♣ "could be short", couldn't tell me when it could be short, but was happy to Alert the 1NT rebid and explain it as "13-14 balanced" (playing a 10-12 and minors "nat or BAL specific range".)
Yes, I want to know how many diamonds they could have. Yes, I want to know if it could be anything other than 4=4=3=2 (for choice of defence reasons). Yes, I want to know if 1♦ Precision could be 1 or zero.
So, similarly, if they're playing "we open whichever minor we feel like if we're going to show a balanced hand" I want to know that too.

This.
So... you believe that one should alert if there is a potential four-card minor on the side, but not a five-card minor? LOL something is wrong here!

In post #30 you wrote that you didn't believe it should be alertable to open the shorter major with 5-4, but that it is somehow different with 4-3.

The difference is that opening 1♦ with a minimum hand with 4♦ 5♣ is a common solution to a well known problem in standard bidding. But opening the shorter minor with 4-3 is an unusual agreement.

Just to be pedantic here: sometimes opening the shorter minor, i.e. not always...
And no, this is not a Canape system, either. E.g. a 1♣-p-1♦-p-2♦ sequence promises 4 diamonds in both hands. The ♣ can be 3, 4 or 5. There is no method to find the length of the ♣. And there is no method to always find a 4-4 fit in a minor. E.g. after 1♣ opening, responder will not bid ♣ with 4 cards. The opener will not repeat ♣ with 4. Thus, the 4-4 fit is never found.

No, I didn't. I said that ACBL regulations do not require an alert of a 1♦ opening when opener might hold five ♣.

That's a bit of a mouthful though, and doesn't even tell them that we do promise three cards.

I think I have reached the tentative decision that I will announce my system, in part, as "5 card majors, usually better minor".
