(razz) bet/fold river?

[RustyBrooks]

I think betting the river is mandatory here, since the player with A9 will definitely call if he makes it, and the other guy will call with any 8.

If the guy showing 83 raises, should I still be calling? He's a total unknown, just sat down and has never played razz at these stakes in the last 3 months, so I know nothing about him. The A9 guy kind of surprised me, he doesn't seem the type to call down here.

Razz ($0.50/$1), Ante $0.10, Bring-In $0.15 (converter)
