The same as toly's - where all the knuckles line up on the same bevel. If you raised your arm straight up in the air and gripped the racquet with your hand in a neutral position (no wrist ulnar/radial deviation), the racquet and you forearm would make a right angle. Doing the same thing but with a pistol grip moves the angle up a little aka decreases the beta angle (x and y axes). toly's 2.2.2 figure is a good visual since this description is like a serve position for the arm. This grip can obviously be used for a forehand even thought I'm describing how to locate it like a serve (I know Nadal and Novak use it at least).
