what CAN'T chimpanzees beat us at?

Physical strength aside, it's always been difficult for me to think of Koucky winning a fight against a chimp because I am a person, and Koucky is a person, and my experience as a person makes me think that people's rationality, at least in terms of survival, is diluted by an awareness of and concern for others - animal instincts are more unflinching when it comes to self-interest and survival, I think (although, following this logic, maybe Koucky COULD beat a chimp at a fight? Maybe it's a bad idea to open the blog up to the chimp debate). Anyway I was just reading this study about how chimpanzees are rational decision-makers.
