Couple of different perspectives...

HJ's play is very often a free card play with a flush draw or 2nd pair.

Sure he could have hit a set of 4s. Sure he could have K better kicker. More likely, though, is a free card type hand. As such, I lead the turn (it takes a special type of player to pop you on the turn again).

As played, though, after villain checks behind on the turn (confirming the fc play), the choice to lead the river or c/c or c/r is image dependent (c/c looks right unless villain perceives you as a lagass/bluffer; this because you are never getting a better K to fold).

If your image is such that you've been firing at various pots when weakness is shown then you, again, can fire away. More likely, though, villain will read your turn and river checks as weak and may think his T9s is best or he might fire 1 bet as a desperation bluff.
