Pot bet the turn, you probably have the best hand.

If the board pairs/flushes on the river its up to judgement, but a check would be recommended to start with.

Let's say you check a turn, and check a paired/flushed river and he bets, you can often easy fold though it's not probable he bluffs with in a "empty" sidepot... Even if its not 100% sure bec. he might want the best hand out and thinks he beats the all-in guy...
