[AKQJ10]

[ QUOTE ]
I was thinking the same thing at first however example: A-10 board reads A,A,5,10. Although generally a set refers to a pair in the hole I do believe it can also refer to a single card that makes 3 of a kind on the board.

Some people use it that way, yes, but the majority opinion is that they're wrong.

They're also giving up a good deal of descriptive value; AA on an AT5 board is much stronger than AT on an AA5 board.

Incidentally, my understanding is that the term comes from gin or other rummy games. In those games you'd almost always make a "set" by drawing a third card matching two in your hand, FWIW.
