The worst poker mistake I ever made was in an online tournament. I thought I had mastered free poker games, texas hold’em specifically, and was feeling invincible. I had a pair of queens, and the board showed two low cards. So I went all-in, thinking no one else had anything better. Turns out, someone was sitting on pocket aces, and they wiped me out. After that, I stuck to playing poker online not real money for a while to avoid losing more cash. It was a hard lesson, but I learned how to be more patient and strategic with my bets.
