One thing I've noticed over the last several years is how useful head movement is. Slipping, bobbing and weaving are terrbily efficient ways to avoid punishment and frustrate opponent's. They also set you up for a wide array of counter blows. One difficulty I've seen among practitioners, especially those from arts who don't usually employ head movement, is the ability to go from a very static, sometimes stiff posture, into evasive tactics. I think a good step in curing this problem is to start from a dynamic position. In your on guard position, rather than standing stiff and motionless like a photograph of someone in bai jong, try making little slipping, bobbing and weaving movements. Not over exagerated or even full movements, but small, perpetual evasive movements will do. It seems to be easier to slip a punch while my head is already moving slightly than to have to start from zero. An added bonus is that it makes you a more difficult target to begin with.
