NL 50 - River value bet

[YKMM]

Button has $25 left and is a terrible player in general 52/5/1.0 in 100 hands. He is likely to call any Q here.
Standard river value bet? Or is betting smaller sounder?

If you laid $12 on the river do you think you could fold to a shove?

He may be likely to call with any Q, but is he likely to have called two barrels with a J?

If you put him on a Q, I think this is a good value bet. If you bet 3/4 pot, you only leave him with about $3 or so, so just pushing the river looks good to me. I just fear you're making a bet that is more likely to be called if you're beat. Of course, I play NL10 so I'm used to being called down by 2nd pair. Dunno if NL50 fish play the same.
