I just had this happen to me on Sat. I'm in a little tournament. I said to the guy we better get a referre. He says. I'm going to shoot it real soft so it will be easy to tell. He reaches down and aims the shot and makes a horrible hit and then reaches over to shake my hand. The match was over. he just walked away with no discussion.
Bottom line. On a close hit either way always get a ref. And not just anyone.
Wait. Did he know that he'd just lost or was he playing off like he'd just won. Also who was the winner according to the tournament brackets?
