But isn't trying to cheat just as bad as cheating?Intending to influence the dice is not cheating. Only actually influencing the dice is cheating.
If someone truly believes that they can influence the result of a die roll and attempts to do so, how trying to roll an evade through a practiced motion any different than microwaving dice? One might have a demonstrable effect, but both attempts are an effort to cheat the other player.
And beside the question if it works or not, if the player think it works and tries to exploit, the other player can also believe in the efficacy of the "cheat" in the same way, and therefore has the right to ask the opponent to stop it or call the TO.
