Check your distance....try not to allow him to get in close other wise he will have the advantage being a wrestler/jujutsu man- use your kempo strikes to keep him out and away from you- work on your speed strikes and 1-2 combo's for the match- attck high then low, low then high that type of thing, remember though that he will close the gap if he see's an opening- keep moving don't stand still or he will tackle you, best you win by a stand up game, if it goes to ground he will again have the advantage.
