How would you fight a chimp?

I'm just wondering if the chimp has any weaknesses on its body that i could use for self defense if the super strong came after me. i know in a natural environment i would stand a fairly good chance because i can run faster than a chimp and make natural items into weapons before he finds me again but is there any bodily weaknesses that a chimp has that i could exploit against him if i was trapped in an alley way without a weapon? and is there anyway i could subdue the angry primate by speech or actions?
