50NL: Standard set value decision

[Chomp]

Villain has been sitting for only 21 hands, running 29/0. So basically unknown. I have no reason to believe he is either a maniac or an imbecile.

This spot is so standard, I am surprised I've been thinking about it. Anyway, I think the issues are obvious enough.

Thanks.
