1. I bet more on the turn if he is chasing a flush your $$ dry up on the river, if he comes back at you then he probably has KJ. Also the board just became a lot scarier with straight potential. As is you have to call the river AI

2. I'll call theres a good chance you're outkicking him. I may check call the river to try and control the pot tho.

3. If he has 67 sucks to be you at 60/4 he could easily have 2 pair. I play it like you did.

4. A lot of heat there prob safest to fold. But its only another $4 to cover them both and they are laggy donkies one of whome is short so you are ahead of his range, sometimes I fancy a gamble.
