At the 2011 Toronto National Tournament the ACBL board of directors approved two changes to the Alert chart, as follows:

"Item 112-49: Alert Chart

A. Conventions and Competitions Committee Suggestions – Alert Chart

Remove the requirement to Alert a cheapest club bid response over a NT opener or overcall, regardless of response structure. Rebids by notrump bidder which are different from standard (such as “Puppet Stayman”) would still be Alertable.

B. Amend the definitions of natural openers to include a 1C opener on specifically 4432 with 2 clubs and 4-4 in the majors.

Effective January 1, 2012."
