The thing is, you're beat by a lot more hands than you beat. You want to see if you can chase opp off a better hand rather than waiting till showdown. You are beaten by: QQ, QJ, JJ, 22, and Jx. You beat AQ/KQ/KK. See what im saying? When the board pairs, I don't think my 1 pair is any good. If I bet and get a call, its more likely that OPP has one of the hands we beat. If I bet and get raised, we can dump safely knowing that we are smoked. And hopefully if opp has Jx, we can bet him off his crappy kicker.
