1. My flop bet is just a small cbet. Turn is a slightly below 3/4 pot second barrel. Why is the turn bet size bad?

2. I put villain on a draw or a small pair here so my reasons for not raising were: 1. Fish don't fold draws (and fish don't fold period) 2. My hand isn't good enough to play a big pot with but I have very good equity against his range 3. It's fairly easy to see if he hits or not 4. Fish like to bluff the river when they miss.

3. I thought that villain has air here a lot of the time, so I decided to let him throw out another barrel on the river.
