Fair play and equal chances.
Sportsmanship is brokered by good strategy, clean skill, courage, nerve, intelligence, and honesty. It thrives on a pure love of the sport, the game, its rules, and its players. It respects the full rights of the hunter and the hunted.
It’s in poor form to take an unfair advantage. Competition risks failure, and when you inevitably lose, don’t sulk, sneer, or offend. If you’re wrong, admit it, stand down, and be reasonable. Don’t blame anyone but yourself.
Earn your way honestly and cleanly, and no one can take that victory away from you.
