Hero 60000, MP 30000, CO 25000.
MP raise 1400, CO call, hero hold JhJd at BB sqz to 5400, MP fold CP call. pot 12650

hero bet 3200, CO raise to 7000, hero call, pot26650
river 2s,
hero check, CO shove 13000, hero fold.

My image on the table is tight and passive. Not that much information of CO, kind of solid.
My thought was a kinda dry flop, I did not want to make the pot that big. OTT, I bet 1/4 of the pot which I want to make a block bet, the reason was the same, I did not want to paly allin with JJ on this board. There's the combinations which I thought CO can reraise ott, Qx(AQ KQ), TT, flush draw like 89hh, 78hh, 79hh, K9hh, or some AA, KK.
OTR, I fold to shove which I do not think it's a good fold right now.

Should I cbet flop and fold to any raise?
As turn played, should I fold to reraise ott?

Or how you will play?

Thank you so much.

Hero played with mobile device without statistics. Just saw some hands that open range a little bit wide and was aggressive. And was caught bluff with missed flush draw hands before.

I think my play had some problems. Please give me some advice. Thank you.

BB is an ABC player can play good hand and make nice fold sometimes play a little bit too much marginal hands. CO is a loose and passive player cannot fold nice hole cards no matter what board cards are most of the time, like a calling station.
I do believe my decision on turn was wrong. The best action was flat call to see the river. CO could have a hand like AQ or QJ and probably would never fold so I went allin on the turn.
Questions:
1, what is the best way playing this hands?
2, how to calculate the pot odds on three way pot? Would (2755-855)/7240=26.2% be right?
3, what is my winning rate on the turn? Suppose BB hitted the straight on the river, should I consider 3 persons' win rate or just make it 2?

Thank you very much in advance.
