[50 NL 6 max] overpair riverdecision vs overbet pot

Villain is unknown maar lijkt decent, over 152 handen:
21/18 , CO st.=38%(6) , CB=67%(6), AG=29% (river=25%)

Ik underrep mijn hand lichtelijk en had wellicht flop of turn moeten raisen. Villain overshovet river, ik heb hem covered.
Callen we hier en waarom?
