Good rules are rules that do not essentially change the appearance of the game, so chess variants are out. Fischerrandom is out. Chess squares and pieces shouldn't be changed either, so Capablanca variant chess with the Chancellor piece is out. ===
The CHESS PLAYER HONOR OATH
(To be recited at the commencement of the tournament day) Raise your right hand.
I am a chess player.
I am an honorable person.
I will not lie, cheat or fix games nor tolerate any among us who does. I will not pre-arrange game results.
I promise to do my best in every game and to conduct myself most sincerely. I believe in God who sees and knows everything I do and even without God, I believe in Truth, Honesty and Fair Play. This is my honor oath. May I suffer the consequences if I break my oath. May I receive punishment if I am untrue to myself. So be it. Amen.
