i mean i fold nearly 100% to someone with those stats who c/c 2 streets and then bets nearly full pot on a river that will almost always affect hero's range and hand strength.

put another way, it looks like hero has a straight alot in this spot after betting flop and turn on such a draw heavy board, if villain checks OOP then alot of the time hero decides not to vbet such a scary river, cos if hero has the lower part of his range (lowish str8s sets or 2 pairs) then he checks behind, and the villain loses alot of value.

all in all it looked value like on the river, these guys dont tend to c/c c/c donk on this texture vs someone who looks like they have a hand with air.
