playing 1/2 today, and it is still fairly early in the session. Hero was just coolered on an earlier hand with AK on an AK5 board. That villain had 55 and held. 2 hands later, Hero has his full 300 rebuy and is in late position. Our SB is the same villain from earlier, with the BB our new villain. SB has hero covered, BB started the hand with ~ 200. Neither player seems too skilled, but i could be wrong. Hero is dealt 78hh into a limped pot. Hero decides to limp this time. The flop is 872 rainbow. SB leads for 10. BB raises to 30. Action on hero. What should hero do?
