DAVE21265:It's like that person is saying " I am going to keep him waiting as long as possible". It just makes me think "grow up". It does not affect my game either it just spoils a good game and makes it boring.
Why make up shyt in your own head? How the hell do you know what another player is thinking? I would say the problem stems from your attitude, not your opponents timing.
There could be a 1000 reasons why they do it. Sometimes I miss cedes and sometimes just notice its my shot when the timer is halfway through. Not gamesmanship, it's usually because I'm rolling or smoking one.
