Yeah I would never open ATo or KJo UTG and certainly not QTo and KTo UTG+1. Those are hands that are so bad when playing OOP.

And there's a lot more hands that I wouldn't open with there, but I'm tight.

As far as button opening ranges go, given the rest of the field folded, anything between 40% and 100% is okay depending on the blinds (VPIP will be a lot lower since you can't open when someone else opened already). Vs tight blinds I open ATC but vs avid blind defenders I only open with playable hands.

I think choosing to open 85o on the button DOES matter in some situations, cause if the blinds are folding to steals 95% of the time, you are leaving value if you don't steal with trash on the button. But I'm not sure how much this accounts for in the winrate.
