Knowing anothers hand enough to overcome your piss poor hand

[arod15]

One thing I found playing various B+M rooms is people talk too much. They often times tell you how they would play a certain hand and why almost mapping their play for you. With than in mind, is entering a pot vs. somone you know for a fact has KK or QQ (not AA as they also said what they do and why) worth a chance with a trash hand? for example there are three ways to skin him you can represent an A if it falls, you can hit a monster flop, or represnt a you got a big piece on a scary flop. I just think that knowing anothers hand might make a sometimes unplayable hand worth a shot. Comments? Thought? lets discuss.....
