The way Harnmaster handles grappling you first match the level of success or failure of each participant's appropriate skill roll (Unarmed Combat or a martial art skill) on a two axis grid, one axis for the attacker and one for the defender. The levels of success/failure in Harnmaster are Critical Success, Marginal Success, Marginal Failure, Critical Failure. You cross reference on the grid and it tells you what the next step will be. If the attacker has successfully grappled he can attempt to exploit the hold which requires a further Unarmed or MA check and a test of strength against strength (each side rolls 2d6 and adds their strength to it and highest total wins). There are various things you can do with an exploited hold like squeezing, choking, restraining, attempting to dislocated or break limbs, imobilise etc.
