The utilisation of defensive and counter action skills that provide cover and deflection protection capabilities against wide ranging incoming directional and angles of attack increases safety and reduces risk especially against the factor of confusion.
Extra sensory perception in regards to executing single blocking actions is a sure means to increase the risk of injury.
Never presume anything and if your defensive capabilities are required from stationary and are based on specific individual blocking techniques to neutralise specific striking skills then the risks are increased by considerable if you get it wrong.
You are far better to have a generic means of reducing bodily target mass and increasing stability cover guarding your body line and deflecting any inward or upward strikes that come inside your cover guard.
Having a sound cover guard from the highest parts on the side of your skull above your ears combined with using a crouched small squat will increase stability as well as providing body line cover from the top of your head to midsection against round house strikes.
Simply deflecting straight or uppercut strikes with the directly opposite inner forearm will redirect the striking arm towards the enemy’s free arm neutralising both arms for that split-second in time.
Your lower quadrants can easily be protected by a stationary evasion pivoting manoeuvre transitioning your body from front on to side on combined with a lead stamp kick and side cover guard.
This means of crouching and covering deflecting or pivoting and stamp kicking provides a static means of providing maximum bodily cover guarding combined with the most powerful unarmed counter engagement of stamp kicking. One means of stationary counter offensive assault reduces risk of failure against formidable threats.
