Tennis psychology is nothing more than understanding the workings of your opponent's mind, and gauging the effect of your own game on his mental viewpoint, and understanding the mental effects resulting from the various external causes on your own mind.

In Tennis, a chop stroke is a shot where the angle towards the player and behind the racquet, made by the line of flight of the ball, and the racquet travelling down across it, is greater than 45 degrees and may be 90 degrees. The racquet face passes slightly outside the ball and down the side, chopping it, as a man chops wood. The spin and curve is from right to left. It is made with a stiff wrist.
