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

The situation:

The human fighter will be an adult male in his 20's in very good athletic shape. He will have an expert background in various forms of martial arts. And mostly just the practical self-defense ones. Most importantly, he will be armed with a military-style combat knife and will be highly trained in how to use it.

His opponent is a chimpanzee. These animals are on average 3 times stronger than the average adult male. Of course, "adult male in his 20's who stays in top shape" will be more than "adult male". Still, it's obvious that the Chimp will physically superior in just about every way.

Would intelligent tactics (that chimps can't emulate) + good strikes with the knife be enough?

edit: more google around suggests that Chimps are actually 1.5 times stronger than the average adult male, pound per pound, not 3 times.

As a human chauvinist pig, I vote for the man.

Intelligence + training + knife / brute strength.
[I will guess the human would also be quicker than the chimp.]
 
Outcome of this fight is determined just like every other fight. If the chimp understands that there is no way out and the human is a death match rival the human is probably dead, but that would be hard to set up. No one really understands what sets a chimp off, and if it doesn't catch on before the human attacks it will be too late. If the chimp doesn't know it's supposed to be in a fight then the knife is buried through it's heart before it finds out, because I'm guessing the human is being prepped with "kill the chimp or die are your only options here."
 
They would have to rile the chimp up somehow to get it into attack mode before the human even enters the cage.

Thing is that "riled up" doesn't necessarily mean "interested in attacking a particular human." If the chimp has a moment of "what the heck is this all about?" then it's probably dead before it figures it out. If one side of a fight knows it is going to be to the death, and that side gets to declare when the fight actually starts, that side is going to win just about every time unless they really have no way to do any damage. Take the knife away from the guy and he's likely to just piss the chimp off until it kills him, but a trained guy with a knife it will be over before the chimp knows it started.
 
Is it like a pocket knife or like a rambo knife?
 
Ok...i think even if the chimp is preped to kill, a stab n slice at a femoral will put it down pretty quick...my money is on the guy

OR... along the rib cage stabbing upwards to pop a lung..
 
I'd add new rules:

No knife
Human has to draw first blood (to get the chimp appropriately riled)
Its all in the dark
There's a big ass rattlesnake in the arena
 
I say they both would be dead. The chimp bleed to death and the man reduced to bits. Would put my money on the chimp anyway. Knives are too short ranged.

Another matter is if the man had a spear. A trained guy with a spear can kill almost anything.
 
That's too crazy and stupid to even remotely predict.
That's the point. Your scenario is all about the man winning. As others have said, he'd just walk up and slit the chimp's throat. To keep things in balance, you need to allow the chimp's instincts to come into play. The rattlesnake keeps everyone from getting too cocky. Now I am assuming that chimps would understand what a rattlesnake is.
 
Ok ok, 3 foot pointy stick and a big roundish rock...chimp gets to where a helmet and studded leather...

Play some rammstein...

If the chimp is actually in fight to the death mindset before the guy can get started I'm probably going with the chimp. It has enough reach that it's going to land the first shot before the guy can get the knife in play, and one shot from an adult chimp in most cases will incapacitate a human.

That's the kind of answer I wanted, thanks.
 
Tim has the right of it here. The chimpanzee won't understand knife or the man's intent quickly enough unless pre-prepped. The best case scenario for the chimp is it gets some killing time before bleeding out.
 
Yeah, the Chimp is going to know what the man is up to before he even enters the cage. Otherwise it’s stupid.
