When a venue (club, bbo, whatever) publishes regulations, it seems to me incumbent on players to be aware what those regulations are. That said, I recognize that most players don't say to the themselves "I should look at the alert regulations" and then go do so. Aside from that, the regs are in some ways hard to understand. I wouldn't penalize a player for not knowing a particular bid is alertable, for a first offense. I would explain to him the rule and expect him to follow it in future. If he doesn't, that's time enough to start penalizing.
The ACBL alert regulation's definition of "cuebid" is "A bid in a suit which an opponent has either bid naturally or in which he has shown four or more cards." A Precision 1
♦ response to 1
♣ is not natural, and does not show four or more cards in any suit. Therefore, next bidder's 2
♦ is
not a cuebid within the meaning of the alert regulation. This conflicts with what "everybody knows", of course, since "everybody knows" that a cuebid is a bid of a suit an opponent has bid. I can only commend "everybody" to something Robert Heinlein said: "If 'everybody knows' such and such, then it ain't so."
Given that 2
♦ here is not a cuebid, the general rule "cuebids are not alertable" does not apply. However, 2
♦, if it shows both majors,
is conventional, and "most conventions are alertable". This one isn't in the short list of those that aren't. Ergo, this 2
♦ bid is alertable.
BTW, it is
not Michaels. First, the full name of the convention is 'Michaels cuebid", and as I've just demonstrated, this bid is not a cuebid. Second, Michaels, as originally defined, at least, applies to a cuebid of a
natural bid, which 1
♦ here is not. So while a Michaels cuebid may not be alertable (it isn't under ACBL regulations) that too is irrelevant in this case.
I agree, in principle at least, with Fred that a player should not, in effect, lose his right to redress because he failed to ask about an unalerted bid. However, the ACBL General Conditions of Contest say this:
Quote
4. Players who, by experience or expertise, recognize that their opponents have neglected to Alert a special agreement will be expected to protect themselves. ...
6. Adjustments for violations are not automatic. There must have been damage, and an adjustment will be made only when the Alert violation was a direct cause of the damage. Note also that an opponent who actually knows or suspects what is happening, even though not properly informed, may not be entitled to redress if he or she chooses to proceed without clarifying the situation.
It seems that a semi-automatic "you should have known" is not what the regs require, so even if this is generally what ACBL TDs do, it seems not in accord with the rules. Peerhaps we need a test case appealed to the National Authority.
I would not make assumptions about what the 2
♦ bidder thought - I would ask him. At least, I would if I was making the ruling at the table.
It is true that no alert is required if the pair have no agreement - and that usually the TD would rule no damage - but that's not what we're discussing here.
Speaking of discussing rulings in forums like this - it's a fine way to vent, and players may be mollified by the idea that others agree they got a bad ruling, but it will not fix the problem of TDs giving incorrect rulings. The way to do that is by the established appeal or reporting procedure.
