First thing, learn playing. Learn it with holding all(press "c"). When you think you can play, try to experiment a liddle with relaxed joints. First, just relax joints which are don't really in use. Something like if you punch relax your elbow one round before you hit your opponent. Next time do your punch with a relaxed shoulder, or your kicks with a relaxed knee and aim with moving the rest of your body. Its less effective sometimes, but you'll see that your replays will look more fluid
