The villain in this hand is the same LAG from Hand 4. I was planning to check-raise his ass on this flop if everyone folded to my bitch's bet, but unfortunately someone decided call. That made me think that I should fold, since the rest of the table was playing pretty tight and letting my bitch get away with a lot of thievery. Was this a good fold or should I have check-raised his ass all-in again?
