Im not sure if there is a standard or anything. I start by sticking the hook in and rubbing under the chin very gently and slowly. If the snake is going to do something agressive this is likely where it will happen. After i rub under the chin I stroke the middle back and middle sides. This gets the snake aclamated to being touched where your going to pick it up. Then you can use the hook under the front portion of the body and lift from the middle with your hands like you normally would. I always scoop from the underside by sliding my hand under then lifting. I never grab by the sides or the top.
