why did you only 4x preflop? The outcome may have been the same but its only 80 to call...I cant imagine he would slow play that flop if he had a 44,22,jj. Either way, anything he has here is a mistake on his part including a VERY loose FD. Could SB have a mid pocket and doesnt place you on a J? This is a tough situation to be in. I think you have to check here. The odds of him having ONLY a mid pocket pair doesnt seem logical. I would highly doubt hes on a flush draw. He could have J9-AJ and I cant seem to put him on anything other???
