It's hard to crak the tight players of JJ above, you really have to try and stick it to em. The key is to make them play outside their comfort zone, put them on hard decision, or make sure you show a couple of hands you bluffed the pot on. This should kickstart them in to going on tilt or playing looser poker. When they start to play looser, this is where you can gain the advantage because they won't have had much experience at it, rocks don't know how to roll and have fun. As soon as you get the player outside his comfort zone, you've got'em. Alternatively I agree, you should play at different times or on different poker rooms
