The more people in a hand the more likelihood we can get paid off when we do make a hand.
Not much info but sometimes you should see what the turn brings especially with overs, perhaps your opponent is just betting with a J or medium pair. All of a sudden ur KQ fold seems a little weak.
Then if you do happen to bet pre. and you get bet into and fold... Your being exploited because your known to be weak tight. On avg if you call 1 out of 3 times he's making money off you unless your making more money off him that pot u do call.
