I think one of the most important (albeit rather obvious) skills to hone will be in knowing when to let go of a hand, i.e. your continuation bet is getting called down on each street. It's not like ring games, once your stack is gone, your done. I know that was the hardest part of my game to adjust starting out in tournament play. Some calling station (or even someone who flopped a monster) would not fold to my contination bet, and instead of raising me they'd just call. so next street I fire a bigger volley hoping to knock them off their drawing hand and they'd just call. You get the idea. Some times you just have to realize that the AK or pocket 10's etc... is no longer a good hand and give your opponent credit for having a hand and just check (read dependent of course)(also look out for the skilled players who will do this just for this reason)
