(Razz) bet a straight Seven on the river?

[electrical]

I'm playing in this game because the stud games lately have been sparse (and also kicking my ass). Also, what's with Razz suddenly becoming strangely popular with people who like to donk around? I've seen incredible spewage since I first sat in. The 7 seat is not a specialist for sure -- seems to know the rules and has shown a few oddball winners but made no distinguishing plays -- but the 1 seat seems pretty solid.

Is there value in betting a Straight Seven on the river here? Assume villain needs an Eight at least to call, but will often have a better Seven when he calls. Also assume villain will never bet or raise with less than a Seven.

Razz ($15/$30), Ante $3, Bring-In $5 (converter)
