In the EBU (England), where support doubles are rare among non-tournament players, both 2H promising 4 hearts and pass denying 3 hearts are alertable.
This is absolutely amazing! I know the EBU has daft policies, but the idea of alerting a natural 2♥ seems crazy. Luckily no-one has ever pulled me up for not alerting this. Is it not time the EBU changed to a more understandable and logical method? It seems that they rely upon everybody knowing the details of some arbitrary "EBU system" and if you make any call that deviates from this unknown basic, then it is supposed to be alerted.
"Potentially unexpected meaning" is meaningless if you don't know what they expect. There is confusion wherever you look. Take a natural jump overcall. Alert if it is weak, or alert if it is strong? What if it is a strength in between whatever those two extremes mean? What point count boundary separates alert from no alert? Does the shape of the hand affect this, and if so, in what way?
The whole idea seems completely impractical. A natural jump overcall should not be alerted. A natural suit raise of 3+ cards (the EBU got the definition of "natural bid" right) should not be alerted. I would leave it at that, and let the opponents ask if they want. However, if this is felt to be insufficient, I think if a partnership has a specific agreement about length or strength, then there should be unrestricted announcements. In the case of a suit raise after opponent's overcall you announce "4 cards" if you play that, or "11-15 points" for the jump overcall if you play that.
Then I can understand it.
