What realistic chance would a trained human fighter have against a grown chimpanzee?

I'd imagine a trained human fighter would have a pretty good chance against a grown Monkee....

Well the 1.5 figure is about the strength of the same amount of muscle mass. How much muscle mass does a 180 lb man have compared to a 120 lb chimp? I wouldn't be surprised if the chimp had more. Probably not more than 180 lb trained/lean fighter, but I'm not sure, chimps are ripped under that hair:

Yeah, pretty good workout. I was just thinking about how I'm a 180lb man, and I'm quite certain that chimp would be significantly stronger than me.
