First of all, it should be said that you play completely different hands in the blinds than in CO and BU. Because after the flop you play out of position when you were in the blinds preflop. Playing out of position has a number of disadvantages. You can't play your good hands as profitably and with medium hands like AT on an AJ7s flop you can lose a lot of chips because you don't know where you stand. You're opponent could easily have AJ+ and dominates you. If no one raised I would call in the blinds with a relatively large number of hands because I don't have to pay a lot when I'm in the SB. If there was no raise I would call with AT +, face cards, A2s + and suited connectors. If someone raises in front of me and I'm in the blinds, I fold almost everything except TT +, AK. With JJ +, AK, of course, I raise from any position. In late position (CU, BU) when nobody raised in front of me, I also raise with weaker hands such as face cards, AT +, A2s + and suited connectors. So maybe I can steal the blinds and even if someone calls I don't have the worst hand.
