i think you should always pay attention to what is going on even though you can get moved a lot ...i've been at tables for over an hour so you never know so you might as well try to notice how people are playing.it helps to know who's tight and who's raising a lot... who's limping a lot...who's laying down to re-raises who's calling till the river then folding...a lot of things to consider,it's good to have some kind of history
