Yes, these moments happen to most players, and they tend to stand out even more at the late stages of a tournament.
What’s important is that you already did a huge part of the job: 8 hours of satellites + 4 hours of tournament play + reaching the final table. That’s not “just getting lucky to be there” — it already reflects a solid level of skill and endurance.
What you describe as a “stupid emotional mistake” usually doesn’t come out of nowhere. It’s almost always a mix of factors: fatigue after a long session, ICM pressure, the desire not to miss a big opportunity, and a point where decisions stop being fully logical and start becoming impulse-based.
And yes — almost every tournament player has been through spots like: “one extra aggressive street,” “wrong call on the final table bubble,” “overvaluing a hand against a range.”
The difference between isolated mistakes and real improvement is what you do afterward. When you break these hands down, there’s usually a specific moment where the decision starts to drift — either fatigue, incorrect range assessment, or an emotional reaction to stack sizes or position.
The most useful question here isn’t “why did I do it?”, but: what exactly was I feeling 1–2 decisions before the mistake?
