## Chess and the Axiomatic Systems

Before playing any game, we must follow certain rules.  In a basketball game, certain ways of holding or blocking opponent players call for a foul, while in boxing, the opposing players must at least be on the same weight class during the weigh-in the day before the fight.

For mathematical discussion, let us examine the rules in playing chess. These are the basic rules in chess, they are not complete, but we will use them for the sake of discussion: » Read more
