the better way to play this hands is like others hands, you have to observation the villains and how is the range of cards he playing, this hands dont is a premium hands and u have to be careful... look the positions and make a standard of play (like, open raise 2.5x, little c-bet, or if you hit the jack or nine like you say, one check raise is good) ... its too many situations, like drawns or straight drawns... be careful, man, poker is a hard game, its a mind game ...
