In this hand, I knew that 22 was a favorite over any non-paired hand. And UTG would have raised if he had a pair, because pairs are better than non-paired hands. So he didn't have a pair, so I bet until the river because I knew I was a favorite to win. Obviously if you're playing them any other way, you're playing it wrong.
