I have read the rules and have a pretty good understanding, the grip is not considered the butt end of the putter. I still cant wrap my head around why M.K. putting method is acceptable. He clearly sets, pinches, stabilizes, aka anchor's the grip all the way up his left forearm. If i remember correctly Adam S. really putt pressure on the anchored putter b/c he started winning so much. Does M.K. just not win enough to bring it to the table?
