Have you ever lost with four of a kind or straight flush?

I came across different hands in 10 years of playing, I can’t remember everything, but I believe that if you don’t have a royal flush, then you need to be prepared for the fact that your opponent’s hand may turn out to be stronger and act accordingly.

I've never lose this way.
But once, I won with a superior quads.

Today I saw an interesting hand where one person was able to lose with a straight flush. Have you had anything like that?

It's very unlucky. It never happened to me like this.
