People overvalue the fact that half the BB is already posted and complete with too many hands. You are OOP the rest of the hand so you are not going to be able to play it optimally. Being OOP, at times, can cost you a lot of money so you really don’t want to make a habit of playing out of the SB. A slansky book I read said to complete with any hand you would play in LP. That seems like a decent calling strat to use since you have the same type of info as LP when you call.
