Should I be afraid if I get into a fight with a Karate Blackbelt with years of experience and tournaments?

fight dirty... that's how we do it in the hood. mace him, stun him... then kick the sh!t out of him. no matter how good you are, there will always be someone better... so get it right the first time and fight smarter and not harder, you'll last longer... or just get beat up and get it on tape so you can sue him
