Hi everybody!
I have a strange hand, with I can't resolve myself and I have a couple of questions. The hand was played on iPoker, 5$.
From the opponent on CO I have only 100 hands, second this she/he is playing 9/6. Seems a solid, very tight player, and don't saw any strange showdown from he. The blinds are random calling stations.
On the flop I missed the c-bet because I timed out. There was a lot of action on the other tables 
My first question is about the raise on the turn. I see plenty of value on the raise, but I don't know if the size was good.
The second question is about my plan on the river. Taking every info in consideration, I can only see medium pairs in CO's range, can't see any draw connecting to this board or any other combination that the CO can turn into bluff. The only card that he can bet for value and weaker than mine is the A2, but I can't believe that he will flat my raise PF with this or that he miss a raise on the draw-heavy turn against three opponents. So my plan was bet/fold. This plan is totally idiot or not?
I'm lost and appreciate any help. Thanks in advance
