Depends on how many tunneling markers and entrances you have out, doesn't it? How does your opponent know that you're not just tunneling and going to try to pop up a new entrance under him? Either way, it creates an uncertainty for the MI player and can help you to channel his movement to where you want him. Even with only one tunneling marker, it's 50-50 that you're moving towards or away from a concealed entrance; with two markers, there are even more possibilites as regards the concealed entrance:
*both moving towards the concealed entrance
*neither" " " "
*Both moving away from " " ' "
* neither " " " " "
* one or the other moving towards " " " "
* " " "" ""' moving away from " '" " "
You can also confuse the issue by doing a ready/tunnel action sequence to create the impression that you're not moving along ANY tunnel axis when you, in fact, are. Creating uncertainty in your opponent's mind can be more valuable to your game plan than actually popping a bug unit out of that concealed entrance.
