Re: Where is this "Cap always plays fair" coming from?
The smart thing is arguable - Cap's intelligence was enhanced by the Serum; how much his actual intelligence was raised is the subject of fierce debate among the frothier fans, but he definitely has a very enhanced ability to handle multiple streams of information, which are a huge contributor to his tactical genius. Batman's a better scientist and detective, but in the kind of smarts you use in a fight, including terrain and allies, Cap is likely Batman's superior.
