chill guys, grievous definitley ISN'T force sensitive, in fact because he isn't he's extremely succeptible to force attacks, he didn't beat the jedi by seeing what they would do through the force he did it because he uses an unorthodox style based off form 2 that the jedi couldn't predict/defend against, but it is possible that he could probably dodge a couple of blaster bolts due to his superior agility but all it would take is one.
