For a cash game, with no information on villain.......
from the BB, you call the majority of the time, raising with ATo+ or AXs
from the SB, you can raise any AXs as you block AA combinations or fold, never calling because you are forced to play out of position. Sometimes you can call if several callers behind you. ATo+ you can raise or fold from SB as well.
when you have info on villain, you can decide if you want to 3-bet wider or not
