Is AI cheating ?

[Taqwus]

The AI does a bad job of reacting to my assassins and succubi. *evil smile* I've assassinated Pretenders before, and had assassins seize provinces on their own...
I'm quite sure that it doesn't know troop sizes; it's accepted battles that it otherwise would have had no business accepting e.g. it losing 89 of 91 commanders and roughly 85-90% of a 700+-troop army because of the far higher quality of mine (mages present, equipment, troop types).
