I don't if this can be useful, but with ctis I sometimes take indie provinces with an empoisonner: I order him to assassinate ennemi commander (select a province with only commanders, no knights or strong indies). With the indies set to 8 there usually are 3 commanders. When the empoisonner set to assassinate doesn't attack anybody, this mean that there is no more commander. You can now take the province with the empoisonner.
