It's a mental technique, imaginary. I learned this technique from the book Smart Tennis and putting it into practice on serves. It's just part of the preparation of your shot.
Ps: The more you do it , the more options you can create and the faster you decide and visualize (even just a few milliseconds before the shot). I am now in the phase neutralize the server when it's big, attack on the opposite corner on server where I have more time. Try to practice, you'll it pays off
