This hand was played with the fish.
Plan on the flop is to raise cbet but action went check/check.
I think that opponent range is weak but sometimes can have FD but I would expect a lot of betting with FD from opponent even from fish.
On the turn my thinking was that I need to cbet to get value from one card FD but I got min raised. At this point I am still thinking that I have most of the time better hand.
River pairs the board but I do not expect a lot of 3x in opponent range.
What should I do on the river?

When I reviewed this hand I got an idea that maybe checking the turn is as good as betting and I should mix it.
Turn card is not that good for me but it is not terrible. Also I don't think I have 2 streets of value vs opponents weak range. And on xh fiver I can just put my hand into the muck.
