Quoted from RGR:What if those notes where given to a player that had never played the game before and followed the strategy given to them from an A grade player and went on to win Division D in Pinburgh???
They still have to hit the shots, and tourneys aren't won on a single game, especially not Pinburgh. Some of the top A players coach their less-skilled, or less-knowledgable friends at these events regularly. There are rules against coaching during play usually however.
