It may be that in the beginning of playing poker this situation happened to me.
Today it really doesn't happen to me anymore.
When you play cash daily, unfortunately you will often face strong
hands that destroy you.
At some point you say "Well, AA went bankrupt, bad luck" and you continue playing.
That's why I always say that the best way to learn poker is to play cash at low levels and move up as your game improves.
And once you are familiar with cash, learn the moves to make in tournaments, which are totally different from cash tournaments.
In a cash hand a player usually almost never folds an AA on the river, because the situation is simple, at most I lose 2 dollars and continue playing.
On the other hand, in a tournament you are in that limit situation, and I have seen many players who have folded AA KK QQ etc, even having sets on the board.
In the tournament there is the ITM to take into account and then the ICM is also very important for cash jumps.
At least I consider that when you become a player you should be ultra-focused on the game, and you should not make external factors act on you psychologically and make you make costly mistakes.
