I'd bet the river. Some opponents will call 6th drawing to a smooth 8, but I think he has an 8 there more than he doesn't. He'll pretty much call with an 8, maybe even a 9. Some times he'll have improved and you'll lose another BB but that happens only about 1/3 of the time. Less, really, since he probably would have bet some of his improvements (to a wheel or a 6) although he may be going for a check raise here.

Checkraising on the river is so infrequent at low levels that I almost assume that a given player won't do it until I see otherwise. So I think he probably either has a 7-9 on the river and will check-call. More than 2/3 of the time you'll win an extra bet, the remaining time you lose an extra bet, so I think a bet is good. I actually think these estimates might be conservative and you'll profit more than indicated above.
