In my opinion, the possibilities for cheating are limitless! My view is this: if a player uses something that isn't explicitly prohibited by the rules and can't be detected, then it's not cheating, but rather small military tricks!
It is forbidden to use cheat programs, codes, or additional programs that alter the game structure.
Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up,
Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil;
Rejoiceth not in iniquity, but rejoiceth in the truth;
Beareth all things, believeth all things, hopeth all things, endureth all things. Charity never faileth...
