Nielso, the question on the river becomes dependent on your read of a player.

If your read is:
1.) He bluffs this card a lot
2.) He values this card if he hit it
3.) He doesn't value an 8 or 77 like this

Then call

The best way to be less exploitable from villains perspective is to mix up whether or not you bluff the card and make some thin value bets with 2nd pair type hands
