In this area of the website you will find conditions of contest for ACBL events. There is one column of general conditions which apply to all ACBL events and separate general conditions applicable to Pair, Swiss, B-A-M and KO events. Additionally, specific events have other conditions of contest which apply only to them. At the bottom of the page are the appendices which are referred to in some of the conditions of contest.

Please check to be sure you have read ALL applicable conditions for any event you are going to enter. If you have additional questions please contact the ACBL Tournament Department.
