John,
Thanks for the various explanations, good stuff. If I read them all right, it sounds like you're saying the "proper" course of action should have been for DJ to be assessed a one stroke penalty, in which case he would have effectively lost the hole. It also sounds like both DJ and KN, could have plausibly been hit with a "both players agreeing to not follow the rules", and both been DQ'd?
Kevin,
I understand your point, but given there are all kinds of gamesmanship tactics in Match Play to get in your opponents head like making 'em finish very short putts or "accidentally" jiggling coins in your pocket, how is calling out your opponent because he fucked up and deserved it, as an attempt to rattle him, also not one?
However, given Kevin did give him the benefit of the doubt and didn't enforce the penalty, resulting in a halved hole instead of a lost hole, i'd say Na is pretty bullet proof on this one. Sad its being turned around on him as a form of victim shaming.
P.S. Seems they dodged a bullet on this one as Peter said, imagine if the halved hole had resulted in DJ advancing to a playoff with McEntyre and he ended up getting bounced?
