I don't know why you guys keep saying in the ACBL cue-bids never have to be alerted. Repeating it over and over does not make it so.
Here is what the ACBL regulations on alerting cue-bid actually says
Quote
4) CUEBIDS
Most cuebids are not Alertable. However, any cuebid which conveys a very unusual or unexpected meaning still requires an Alert.
EXAMPLE: 1♠-2♥-Pass-2♠
If the 2♠ bid is a heart raise with values or some constructive hand, no Alert is required. If the 2♠ bid is a transfer to clubs, an Alert is required.
EXAMPLE: 1♦-2♦
If the 2♦ bid shows the majors (Michaels), clubs and spades (top/bottom) or some other two-suiter (not including diamonds, no Alert is required.
It is fuzzer that that, since 2
♠ on the auction here would seem to be a cue-bid by the definition that it is unlikely for the bidder to want to play in spades (consider it a viturtual cue-bid), but this is unlike normal cue-bids and there is probalby no set way to play this bid. For instance, don't you think it should be alerted if it is a weak bid showing clubs? How about a top/bottom cue-bid? What if 2
♠ here showed a good 3
♣ bid (and an immediate 3
♣ was weak, while a 2[NT] bid here showed a good 3
♦ bid (and an immediate 3
♦ was weak? There is so much 2
♠ coud be.. michaels, transfer, top/bottom, diamonds and a black suit, take oout of spades, who knows. And yes, some people (not me) might consider this to play (yuck).
I would think 2
♠ here is odd enough, and non-standard enough, that it is "self-alerting" and the opponents have to ask what it means, but the fact that the next hand doesn't ask, and just passes, might that not send UI to the 2
♥ bidder? (I don't care what it means, I am just glad I didn't have to bid 2
♠ with this minimum no-fit hand).
This virtual cue-bid is very similar to situations with unusual versus unusual. Here, we cue-bid their suits with specific meaning, and when we don't cue-bid their suits, that have meanigs as well.. So well ALL ALERT our "cue-bids" then (or we should, it is alertable). So why not here? And anyway, at the very least, everyone needs to stop spreading the false story that cue-bids in ACBL are always not-alertable.
