My first thought- fire another shot on the turn. After thinking this through I'm not sure as I follow the following logic trail. The pot is T450 on the turn and a 1/2 pot bet shows weakness IMO so that is not the right play. Anything more than 1/2 pot and you're committed so you might as well push if you're going to bet. You don't want to push as a flush is one of the few likely hands given the call on the flop (i.e. what would someone call a pot sized bet with when the two J's show that they would NOT have raised with preflop- flush draw, maybe KJ,AJ,QJ). Since there was no raise preflop (eliminates AA-QQ from his holdings), and you know where three of the J's are (reduces the chances he has one), I think you are left with a flush draw as the likely calling hand on the flop. I like the play and the fold.
