How am I being thick? It all comes down to gaming fundamentals and you know that. In a platformer, if there is a hole/pit, you jump over it. In a fighting game, if someone throws a punch or a kick you either block or counter. In a FPS, you shoot while strafing and throw well placed grenades at an enemy, not running around like a chicken without a head like the players in that video did. Everyone has a 50/50 chance if they know what to do and probably an even higher chance if they are a pro despite what advantage the opponent has.
