You have a lot of dead hearts out but I still think this is worth a completion in your position, so I like the third street play. Having completed, fourth street is a mandatory bet imo. I think the fifth street check is ok since you checked fifth, however if you had bet fourth, you may have been able to pick up the pot on fifth with a bet. Sixth and seventh looks fine, however a good case could be made for checking sixth.
