I put "yes" but I really mean only EP except as a mixup. If I do, it's on a table that's loose passive PF and I have a weakish implied odds hands. Also, if there is a super fish at the table, I want to see a flop as cheap as possible with anything reasonable, so depending on relative position, that could mean open limping with some wierd stuff sometimes (Q7s) with terrible player on button or in the blinds.
