If your opponent is Counterstriking all the time, just Feint. You get to attack and he doesn't.
If your opponent is Block+Striking all the time, then most probably he is not in a stance. Go to Defensive Stance and Counterstrike. You've got +2D every action. And maybe his Block doesn't even go off? Not sure. Or you can just Feint and he's at -1D every action (he must put at least 1 die into Block).
If your opponent has 3+ more dice than you and is B+Sing all the time, so that these tactics don't bring you to his level of dice, and you don't have any other redeeming qualities like a high Power to Charge or Push or something, then yes, you are going to lose this Fight! badly, as is proper.
