Strategy adjustment with overs

[kurosh]

I posted this in B&M and didn't really get much in terms of strategy. If you don't know what an over is, basically if everyone remaining in the hand has an overbutton, the stakes double on the next betting street. Preflop doesn't count. I play in a game where nearly everyone has one so it's like having mini-blinds.

If there has been a post on this before, sorry. I couldn't find it. What strategic adjustments do you make?

Implied odds go way up. I'd guess PPs become much more playable. Probably shouldn't try to steal with marginal hands. Drawing hands are no good.

The game I play in is full of semi-loose passives who play horribly postflop. I'm wondering if I can loosen up even more than usual because of the overs.
