tricky TPNK hand 15/30

I lead out the flop and fold to any aggression. Turn, i play similarly based on the action to this point (CO=T9? or 99? don't think he has 99 or he would have bet flop in position, maybe TT slow play?). Turn, you would have to call reraise of 140 into a pot of 460 and 2 players to act behind you. Your getting a little better than 3:1 (not the odds you need for the flush draw on the river)and at this point you dont really know, but your A may be good (not likely, but thats why i like a flop bet). I call the turn raise. Rivers tough. you have to call 300 into a pot of 680. roughly 2.3:1 with nothing but TPwK. I hate the BB tag along, but CO maybe desperate enough to be playing a 9x with his short stack, so I make this call and pray BB doesn't push over the top. The flop play sure has made this tough on every street down the line.
