1. River donks after c/c, c/c

1. River donks after c/c, c/c lines are almost always value lines
2. Passive fish do not play draws aggressively
3. Passive fish are afraid of being outdrawn and will often over-protect their made hands against draws
4. Passive fish give up when their draws miss and don't turn medium strength hands into bluffs
 
Given 1, we tend to assume villain has a value hand.
Given 2, we suspect his range for c/c flop is mostly [7x, FDs]
Given 3, we would have heard from Jx on the flop and 76 on the turn.
(Note we are largely discounting 4x and 2x from villain's OOP flatting range @ 25BB).
 
=> A passive fish's will almost always have a flush when he donks the river here after c/c 2 streets on this board
@ These stakes 80% of players are passive fish. 
If we always folded our top pair vs this line in this spot on this board vs such a population, we wouldn't be making a large mistake. 
 
Even if it feels gross folding top pair, I think you have to make a disciplined fold here.
