Player X, big, big strong character tries to shove aside much less strong and lower level character to get on his way to something. This happens somewhat on surprise and on the surface maybe seems cut and dry. Str v str and really no chance of big, big strong character losing out unless you have a GM that operates on the 1s and 20s principle (which I do btw). It should not be a foregone conclusion that bigbigstrong just gets away with what he's trying because he's inconceivably stronger than the other lower level character. Lower level character may have something that gives him initiative (ie insanely high listen adds, and has a chance to hear it coming, or premonition spell up and GM allows for the player to act etc). Maybe lower level player wants to get out of the way rather than take on what is nothing short of a charging bull. Maybe lower level character wants to stop bigbigstrong but isn't going to be so silly as to out strength him. Maybe he has a spell ready, maybe he wants to stick his foot out and trip the guy (at the risk of breaking his own leg in the process), maybe he wants to put a 'kick me' sign on the guy's back as he passes because he's a Shadonite. It's really never, ever cut and dry. The more people you add into the mix the more layered every single situation becomes. Incidentally this is why quests with higher turn outs will always go over. It's not about GM's miscalculating content, it's about GMs not anticipating the amount of player element that's going to affect things. Anyway, total side tangent.
