I have been opening 3BB UTG, 2.5BB in HJ/CO and then 2.25BB on BTN. My thinking is to make it unattractive for people to play me when I am out of position, and give me a cheap price on the steal.

However I see that MMAsherdog does the opposite, opening smaller UTG and larger on the BTN. His thinking is to reduce pot size when he's OOP and build pot when he's in position

Which approach is preferable?
