You mean this guy? Run silent, run deep. I always wanted to say that, LOL!
If he's not dead ahead, turn onto an intercept bearing with the contact and go to silent running immediately.
Do your TMA and classify him. Try to get off the first shot.
If he does fire, use decoys and knuckles. Put the layer between you and him if you have to, and be prepared to take evasive action, but don't lose the wire.
