Playing with ultra-tight players

I think the key to winning is to play tight/agressive most of the time. Occasionally however you have to loosen up your game a bit. If I'm in a tourney and have a decent stack I will often take a look at hands like 10-8s 67s, number one because if I hit the straight on those hands I'm usually a winner and it shows the other players that I'm willing to gamble. It's alot easier to win a hand if your opponent can't read you.
