i had two officials at the state tournament tell me that it is legal to pull one finger to release your opponents grip from your wrist if you do not "pry" it back. is this really in the rule book? and what exactly is it that they think causes them to let go when you pull it off if not prying? i talked to several coaches one of which is also an official and most of them thought you had to have all four fingers in your grasp, some thought 3 but not one thought you could pull one. any thoughts???
