Norway seems to having selected a (slightly) different approach:

(My translation): [
] Different environments have different expectations to
the meaning of calls. Thus basing alerts on “common/unusual” has therefore
proven unsatisfactory. Regulations are now mainly based on


The main rule is that all conventional calls shall be alerted [a few

- “natural” calls containing essential understanding beyond what follows
from the call being “natural”. 

- “natural” calls with reasonable doubt about the demand level.

- PASS when conventional [e.g. expecting a subsequent call other than PASS
from partner] 

- DOUBLE and REDOUBLE when conventional [i.e. not solely for penalty]


So for instance both a transfer bid and the response to this shall be
alerted as neither promises at least some required minimum length in the
denomination named in the call.

Alert — A notification, whose form may be specified by the Regulating

Authority, to the effect that ++opponents may be in need of an



Aussie Regulating Authority:


3.2.2 Two classes of natural calls must be alerted (unless they are

self-alerting), viz.


(a) The call is natural, but you have an agreement by which your

call is forcing or non-forcing in a way that ++your opponents are

unlikely to expect++.



[e.g. 1 banana – X – XX – Pass = unexpected strength, not expected

balanced weakness]


(b) The call is natural, but its meaning is affected by other

agreements, which ++your opponents are unlikely to expect++.
