Sb is a reg. My first question comes otf, I didnt knew what to do with this hand when he checks, I dont see a lot of value in betting and if we bet we bet mainly for protection, but I think that he should check this flop quite often bvb and if he plays good his checking range will be well protected. Turn call is standard, I dont see other option there, but otr when he bets again I dont see a lot of bluffs in villans range, I really try hard to found some.
