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.
Never break your word. Never ignore an insult to yourself, a lady, or your flag; 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 (except in open war). This only applies between gentlemen.
