Either fold turn, or call down.

You can't always just regurgitate stuff like this. There are many situations where calling the turn and folding the river is the correct play.
In this case, like many others, the fall of the river card turned a possibly +EV call down into a definitely -EV river call.

I'm not convinced the call down is +EV in the first place but I'm just making a point.
