I don't think I'm like that myself. I analyze the players who are playing against me and that's good to take the concentration away from bad players who are there terrified to see cards!
yes, those players who play slowly are annoying, they don't know how to match the moves and it irritates the players and also those who give equal all-insion
On the contrary, I don't like fast game. When everyone plays slowly, there is enough time to think things through. Playing fast increases the chances of mistakes, at least for me
