Check

Check
You can put your target in check as a standard action that draws an attack of opportunity. A checked opponent is prevented from moving from their current occupied square. You can only check an opponent who is no more than one size category larger than you. If the combat maneuver is successful, the target cannot move from its occupied space until the start of its next turn. Attempting to check a foe while unarmed imposes a –4 penalty on the attempt.
