AA or KK isn't automatic nuts. They are best pre-flop hands. AA wins only 50% of time to river in multi-way pots. And then there is also variance. Wet boards kill action on AA KK and much of the time kill the hand itself. AA is winning pre-flop. But post flop you could be up against a wide variety of hands that are better, especially on draw heavy boards. If you are complaining about bad beats and coolers, you don't understand poker yet. Just try not to go all-in and be patient, Good luck.
