Hello guys, hands do you bluff this river?
I'm using a polarized strategy to bluff/valuebet rivers but I'm not sure if 88 is the best canditate in this board since we don't have broadway blockers. Should I just guive up this type of hand or do we still have value in bluffing around 3/4 pot? (no info on the villain)
