55 with oesd, take the free turn card?

[Mur]

I bet the flop with the intention of taking the free turn card. Given how passive my opponents appeared, does anyone bet the turn as well?

If feeling aggro I bet the turn, you have a strong draw here and a bet on the turn may fold out overcards who fear that you have a set. Taking the free card is fine too, given that the pot is small.
