A side-on game of angles, the square cut is to cricket what a near-miss on a red is to a bad game of snooker played by Pagans.
Square everything. Square your footwork; square your bat stroke; square your follow-through. Should time allow, a counter-squaring of extraneous footwork will balance the batsman better and allow for him to play the ball bethwart the point fielder.
If you have a well-balanced bat, midway through your arc and counter-arc, you will reach a point at which it will unquestionably feel a fraction more comfortably weighted. It is at this point that you should completely blank your mind and simply allow the bat to mesmerise the ball. Failure to do this will result in successful execution of the stroke.
Practise this in the nets without a bat, ball or trousers, but ONLY bethwart you or you risk undoing all your good work in an instant.
