Well, Eric, I really have no interest in debating the rules with you. If my understanding is wrong, I hope someone other than you can educate me.
It is my understanding that, if a player causes a ball to move, regardless of intent or even whether he saw the ball move, he must replace the ball and incur a penalty. It is also my understanding that, if a player grounds his club behind the ball in other than a normal way and thereby improves his lie, then he incurs a penalty, regardless of whether the ball moves or of his intent.
So, if Clark caused his ball to move, regardless of his intent, he should have replaced it and incurred a penalty. Also, if, in grounding his club 3 or four times before hitting his ball (an unusual practice it seems to me), Clark improved his lie, then, even if the ball didn’t move and regardless of his intent, he would incur a penalty. If he saw the ball move and didn’t replace it, or if he intended to improve his lie by grounding his club three or four times, then he didn’t just violate a rule, he cheated.
If my understanding is incorrect, I stand corrected.
