I glanced around a bit and didn't see a thread on this. It seems like an important subject since it impacts about half of our hands.

Assuming we are playing with 100BB+ stacks, I've always opened pot. My rationalization for this is very basic - as long as the stacks are deep enough to allow for postflop play I want my pots while in position to be as big as possible.

After watching a few of the elite level videos on here I've noticed that a lot of the instructors are opening less - usually around 2.2x. Is there a rationalization for this that I'm missing? I feel like opening less than pot at 100BB+ should be a significant leak but I have no idea how to go about proving or disproving it. I'd love hear some other opinions on this.
