With some people, nothing will work. But I have had some success with a few people. I just let them know that I know what they are attempting to do.
One guy was commenting on my shots while I was about to shoot. I stopped, looked at him, and said "No sharking please!" He has not done this to me since, although he continues to shark other players.
Another player was sharking me before a match. I said "Are you sharking me?" That shut him up and he has not sharked me since. This same guy likes to give bad racks. I saw him doing this, then walked up and closely examined the rack. I broke and made a ball or two anyway. He now knows he can't pull this stuff on me and gives me good racks.
I think this will work with the more intellegent types, but not with the sore loser - throw their cue out the door (or break it) after losing types.
