Just wanted to pose a question as to how people here perceive position at different stages of the tournament?

I think it's sometimes adventageous to be first to act in the 'first to the pot wins' situations.....so when an aggressive player reraises CO or button raise.....is there a point to calling with good hands(but not monsters) if you know he'll go all in on just about any reasonable flop ...and if u don't hit you'll probably need to fold...so would it make more sense to push?

What about when the action is reduced to pushing? First aggressive player to act often wins the pot...so in these instances does positional advantage reverse?

I hope i am posing my question clearly....
