In an effort to dispel the myth that professional and amateur fighters just aren’t that smart, we now have Chess Boxing. The rules are simple, fight for a round and play chess for a round. You can win with a knockout or a checkmate.
For the record I’ve been fighting since my days in the Marine Corps. I have both a black belt and a Mensa membership card. If you want to challenge me, watch out, I’ll rock your pawns and make your knight cry “momma!”
