Batman v Superman: why Batman has a chance

Ok, let me get things straight.

I'm not going to bring up any specifics (Kryptonite), or come up with a plan for Batman (throw Kryptonite). This is all just theoretical. And it's not just Batman. There have been some other cases where a ordinary human matches up with someone who has actual superpowers, and give the dude a run for his money. For example, the episode of the Flash where the Flash, the fastest man alive, turns on his friend the Arrow, a dude with some arrows. Arrow is able to keep the Flash under control until the deux ex machina comes. People have written this off as not possible and just for the purposes of having a superhero match-up, while not having to fire Stephen Amell as Arrow. However, a human like the Arrow actually has a fighting chance. Putting aside all comic book loopholes developed by writers who had just learned of the concept of overpowered (Kryptonite), an ordinary human is strong because they are ordinary. Specifically, they have learned to adapt and use their resources and environment for them. An example of this is the hidden crossbow scene in the Flash episode, where Oliver tell Barry to run far away, then run back and get hit with an arrow. Barry guarantees he will dodge it, but goes along with it. When Barry runs forward and catches the arrow with a cocky grin, he trigger 2 crossbows behind him, that fire in unison and nail him. This is the perfect example of a human using his environment to his advantage. People with powers have learned to rely on said powers, and can't think outside the box. However, humans have the power of resourcefulness, in that they have learned to use what they have. Sure, in a blank room, Supes would win, but Batman has the ability to use his environment and his numerous gadgets to his advantage. After all, you can't dodge and arrow if you can't see it coming.
