I like this topic. I usually play for 1-3 hour sessions. One leak in my game is setting up a LAG table image when I won't be around to take advantage of it. I need to play more straight forward during shorter sessions, but I almost can't help trying to get fancy. Discipline is a bastard.
Those of you who play tight and are concious of your table image; do you play tighter when you are getting ready to leave, since you won't be around to profit from your loose image?
Do most people even try to change gears?
