Exactly. At worst case it could become a mind game but only if your mind is weak enough to let it happen. And if your mind is that fragile you should not be gambling anyways. This is one of the strangest threads I've ever seen.
It seems many here would never concede a shot and consider it sharking. So why is it that you frequently see professionals concede shots to each other yet I've never seen an argument break out where the shooter accuses their opponent of sharking or unsportsmanlike conduct. They always seem to accept the concession in the spirit it was offered - gentlemanly. And you know darn well pros will make an issue of it if they think they are being sharked.
