Set mining when cheap on the flop is optimum play, playing small pairs after the flop with overcards there is only asking for trouble..
Even the weakest will play paint to the river, flush fishes and Ace rags amongst many other variants will find a way to cook small pairs..
That said..vary that opinion dependent on the stage you are at in the tourney, number of remaining BB, effective stacks including your own and you will find many, better players then myself look to jam any pair late on..the number of times i see a flip in latter stages between AQ/AK v 22/33/44/55
