Opening 1NT with a singleton: It’s officially legal

The ACBL Board of Directors removed a legal gray area surrounding semi-balanced notrump openers when it approved a change to the definition of a notrump opening in the General Convention Chart. The change allows players to open 1NT with hands that include a singleton ace, king or queen, as long as they do not also contain a doubleton.”

Here is the new definition, effective Aug. 1:
“A notrump opening or overcall is natural if, by agreement, it contains no void, at most one singleton which must be the A, K or Q and no more than two doubletons. If the hand contains a singleton, it may have no doubleton.”
