Protect any lady, and anyone weaker than yourself. Never break your word. Never ignore an insult to yourself, a lady, your liege-lord, or your faith; insults may only be wiped out by an apology or a duel (not necessarily to the death!). Never take advantage of an opponent in any way; weapons and circumstances must be equal (even in open war if the foe is also noble and chivalrous). Accept any challenge to arms from anyone of greater or equal rank.
