I would say as a general rule, in limit poker you should be more inclined to call down an unknown opponent. In no limit poker, you should be more inclined to fold.


Also, in a limit game setting, be more inclined to call down if the game is tough, and be more inclined to fold if the game is soft. When you get check-raised on the turn in a soft game, you will RARELY get shown less than two pair.


In a tough game, the information will be valuable, so there's two reasons to call him down. By calling them down, you might beat an overly aggressive player, and this will keep most players at the table from taking a shot at you for at least a little while. Also, you call them down because that info will be valuable and the sooner you get it the better.


Of course, once you know the player better, you will know exactly what to do.
