Mostly true, but when you raise of call a raise with AK, and you hit your hand, most people will be aware of the strng possibility that you hold TPTK. Same is even true when you make a broadway or a wheel. When you flop a set of jacks, It is almost always a suprise for your opponent at the showdown. AK easier to play, JJ more profitable in any cashgame.
