Of course, that player crowding the service box may be doing exactly what he wants you to do, try and hit him. Unless you really do have a 110+ mph serve, he won't have a lot of trouble stepping out of the way of your 'bean ball.'
Thus, after you go for him and miss, you are now down to your second serve...a position he might very well be trying to get you in.
Now, having said that, consider this: if you serve a few down the T and he backs up, away from the center service line back to his normal position, if you really do want to hit him, on your next serve to that court, instead of aiming for him, aim behind him. If you do have a 110+ bomb serve with decent control, as you are in the middle of your service motion, he most likely will be moving back out of the way of the service box...and into the direct path of your serve.
