[Canon] DD Asajj Ventress & RotS Grievous vs RotS Count Dooku
Let's say Dooku summons Grievous to his quarters on Serenno to discuss the next offensive against the Republic. Unbeknownst to him, Grievous had banded up with Ventress to get rid of the Count once and for all. Both of them enter Tyranus' chambers and a duel to the death begins.
Would Dooku beat them? For how much out of ten? Remember that this is canon only. Morals on.
