David Grabiner:

What does 5H mean?

Richard Hills:

It means that North needs a new partner. South choosing an undiscussed jump
to the five level is an infraction of Law 72A's second sentence:

"The chief object is to obtain a higher score than other contestants whilst
complying with the lawful procedures and ethical standards set out in these
laws."

David Grabiner:

.....If partner intended the bid as Exclusion Blackwood.....

Richard Hills:

Zero Canberra players use the Blackwood variant Exclusion Blackwood
(perhaps because that variant is rare and error-prone).
Many Canberra players use the Blackwood variant Minorwood (perhaps because
that variant is rare and error-prone).

Different parts of the world have different preferences for different
Special Partnership Understandings / conventions. Hence different
Regulating Authorities promulgate different Alert rules.

For example, the Aussie Alert regulation requires Alerts and/or pre-Alerts
of natural calls that the opponents are "unlikely to expect". So the
Ali-Hills partnership pre-Alerts that in auctions such as 1H - 1S - X the
double would be a natural penalty double, rather than the expected negative
double.

Best wishes,

Richard Hills
