As I was hitting my putt on the second green, my ball moved. I was in the middle of my stroke, so I played it. Is this a penalty?
Rule #9.1b specifically covers "What to do when ball moves during backswing or stroke." This section says "if the player caused the ball to move, see Rule #9.4b to find out if there is a penalty." I don't think I cause it to move. Certainly not intentionally. But it looks like I get a two stroke penalty for playing the ball from the wrong place. That's pretty harsh.
