NL100 QQ, overpair river decision

[saxhoe]

Villain is 17/1/1 over 130 hands. My read was he could be doing this with a lot of hands because I had been very active at this table. Also I think he would call with anything except total air. But then again, there are a lot of hands he could be beating me with. Is it more than 50 %?
