Typically, a set is for stacking people. It's a hidden hand and destroys non flush and non straight boards TPTK is for winning small pots and thinning the field post flop if you still have 2 or 3 callers. Use your TPTK to make value bets to chase out draws post flop, or at least make them pay. If someone is calling pot sized bets on the flop and turn then slow down. You will rarely if ever stack someone with TPTK so don't try and don't get exited when they are throwing out missles at you when you hold AK or KQ and the board is rainbow with you hitting a pair.
