Hello DontKnowChess,
Using a computer to decide your moves in a board game (specifically chess, checkers, reversi, gomoku, nine men's morris, go, four in a row, pente and backgammon) on FlyOrDie is allowed.

But FlyOrDie members have the right to know if they are playing against a computer. Therefore FlyOrDie uses a system - including analysis of client computing environment - to detect suspected program use, which will be indicated on the concerned player's info screen with a small icon. (red exclamation mark)

Kind regards, 
John
