it doesn't really matter if you start out loose or tight. what matters most is how you play when you're down to 5-7 players, and more importantly how you play in the bubble.

i find it really doesn't matter if you're tight or loose at the beginning. playing loose is like a roller coaster ride, you won't win much, and you'll lose a little. so it's a waste of your time and effort. most of the time you'll have just as much as folding the entire time. it does have the added advantage of building a big stack early on if you catch a run of good cards and bad players.
