109 R not too long after the addon period

Villian is shaniac, he was screwing around a little bit in the rebuy period... I was pretty tight for the most part. I thought he would fire second barrel pretty often here, but was hoping it'd be bigger.

River is a [censored] spot, I was about to say [censored] it POT ODDS I call, but after thiking about it decided to fold. Still not sure about it. Thoughts?
