help playing in league tournaments

[Sendachi 0]

I need help playing tournaments in this league (www.inhousepokerleague.com) at local bars in my area. Play is pretty poor for the most part (loose passive). I've been playing pretty tight and depending on my post flop play to win chips. I've made the final table several times but I'm usually pretty short stacked. After the break, the blinds take a big jump (in an already fast structure). I usually find myself getting blinded away while waiting for something good to push with.So lately I've been trying to play more aggresively to accumulate more chips and I'm failing miserably. I can't tell if it's just impossible to make a move on these guys or if I'm just not doing a good job of picking my times and targets.It just seems that every time I make a move, I get called with anything and it turns into a luck fest.So, my questions are:1) Does anyone have any general tips on playing against loose passive in a fast structure?2) Does anyone have any advice for stealing, pushing, making moves against loose passive?Thanks guys. I appreciate any help I can get.
