Flop - You miss the flop and the board is fairly coordinated, I'm not sure an autobet does anything good here. You have nothing to protect as you haven't made your hand, and you can't bet for value as you're probably behind. HU I would bet for sure, against two players, I would say it's marginal. When raised on the flop I'd put CO on a FD, OESD or TP.

Turn, since CO bets he probably had TP on the flop. If he were on a draw he would have checked behind. I would say you have 6 pretty clean outs to call the turn, which should be enough.
On the river, I would probably call, but I'm damn sure that we are behind here. The reason to call is not only that there is a small chance that we are the best, but also to avoid people taking shots at us later in the session.
