mathematically, changing seats has no impact, BUT... changing seats may in fact help emotionally and psychologically a player who is in a bad card rut. This emotional band aid may, in fact, be much more important than any mathematical strategy you can throw in. More money is lost on tilt than at any other time. If a change of scenery can prevent tilt than by all means, move. Look at it like this.... changing seats can't hurt you, can it?
