10NL: Valuebet this river?

[members_only]

Villain had been playing quite wild. In my first hand at the table, he limped in MP, called my button raise, and then c/r'ed big on an 8-2-2 flop before showing J5o. A few hands later I raised it up from the blinds with QQ, he called, I bet a J-high flop and then stack-a-donked him (expert) on the turn. He called all in with T2 for middle pair.

He may have been drunk as this hand took place at about 2.30 in the morning
