I like eupho's line best. Outlaw suggests a river bluff which, once you learn to spot your spots, is +EV. But for noobies I'll just add what I've learned. Cbetting and then 2barrelling on boards like this with (as jyms pointed out) zero showdown value often FORCES a river bluff, a la Outlaw's line.

Summary: your cbet is a bluff, your turn is a bluff, and on the river the only way to win is to bluff again. If you're not comfortable in these spots, you gotta disengage early, like eupho suggests.
