Depends on the player. If he is the type who frequently raises with 3 suited cards i call as it looks as though he may have made a flush on 6th.
If his raises usually mean pair type hands than i raise the river as he probably has a hand like Queens up.

His check on 5th if he is a pair player usually means he has Queens up and wants to check to see what you do with the kings you are representing.

You check behind so on 6th he feels comfortable to bet his 2 pair.

May be wrong but i raise the river as queens will pay you off almost always.


lastly on another note i think i just call on 3rd to encourage others in the pot. I don't mind playing a multiway pot with 3 cards to the royal. A raise here is effective in isolating though if you would rather do that.
