River decision check up

[Bona]

Reviewing this hand I started thinking about how it should be played under various conditions.

Villain is loose preflop and at least a little loose postflop but not aggressive. Against this opponent I should fold this river right??? But if he had checked I would want to bet it because he might call with a lower pair.

However- against an aggressive opponent I have to call and against a tough and aggressive opponent I have to check through if he checks because he folds anything I beat but might be c/r ing his flush-right???

Tough spot.

against someone generally not aggressive, this has to be a fold, but an aggressive player may be able to bluff at the scare card and you might need to call him.

Against an aggro... crying call.
