Here where I was going with this: seeing a tkd fighter in the oylmpics with his hands down leads me to think that, if he or she gets put in the ring at a full-contact tourny, a good fighter will be able to pick a dozen differant spots to attack. Every single tkd fighter that i have met in the ring has either a) tenses up and can't move or b) keeps kicking and gets side-stepped with a foot to the face. Now maybe I haven't met a polished tkd fighter, but i am just going off of experance. And for markusan, ever been to a World Oyama dojo? Probably not. At my the dojo we have kids ages 5 to 10 fighting in semi-knockdowns. There mums and dads have no problem sending them to our dojo.
