repairing pitch marks on the line of your putt

As i said earlier best not to touch them, if your in any doubt , play it as it lies , if you wana repair them do it after your shot , saves the issues if you do change your mind how to play it ..

IMO If you did change your mind & play over them it would be a penalty , have not come across this but i would think 2 shots .. just my opinion tho , im no rules guru

If you claimed to miss hit it off your line , id go by where it ended up , if it ends up well away from the hole ok you mishit it , if you knocked your miss hit stone dead .. mmm. ? id be wondering ha
