In a normal tournament, folding kings preflop is almost impossible. It’s simply too strong of a hand, and if you happen to run into aces, that’s just bad luck and part of the game. Most of the time, there’s nothing you can or should do differently.
The only situation where folding kings preflop can make sense is in a satellite. If you’re already very close to qualifying and your goal is to secure the seat rather than accumulate chips, folding even a premium hand can be the correct play. In that spot, avoiding risk is more important than winning the pot.
Outside of satellite scenarios like that, folding kings preflop in a standard tournament is extremely rare and usually not correct.
