I like checking or a small bet here and let my opponent define his hand so I know how much I can take him for. If he checks or calls behind then a extra large river bet looks like a resteal.
I think a lot depends on the opponant and your table image. If I have been splshing around in some big pots recently or shown down some bluffs, i'm more inclined to bet out big and build it up. In this hand I think his most likely holding is TPGK so it depends on how aggressive / cautious he gets in these situations.
