I play at a store about 1 hour away and make it down once or twice a month. The group there is very casual in style with a good number of newer players. It's funny sometimes when these guys say the dials "turned on me" and that the turn they set was actually a move 2 spaces away from what was revealed. I actually revealed a 3K in a tournament last night when I had intended a 4K. I lived with my mistake and laughed, knowing my dial had "turned on me."
I also had a guy reveal a dial showing between a 4 straight and 4K. He quickly adjusted it and said it was a 4K. I told him that in a more competitive situation, I would get to pick, but let him slide on it. Did not prevent me from winning the game, but the moral of the story is that players should be careful in selecting their maneuvers or be prepared for the consequences of the rules.
