Pre supposing that the fighter is limited to unarmed conflict, and he hasn't snuck up on you and can only fight you by himself, what kind of fighter do you fear the most? Would it be a huge guy with tremendous strength, a stand up fighter, or a grappler, or a tenth degree blackbelt or an Olympic champion or MMA fighter? Who would you least like to fight? For me, it would be a grappler, as I was always a lousy wrestler, never practiced any ground work at all, and if I'm on the ground I can bite the guy and that's about it. What kind of fighter do you fear the most?
