Passage Summary: A professional chess player argues she shouldn't be punished for humming during games because she doesn't realize she's doing it.

Conclusion: Marianne should not be held accountable for her humming because it is an involuntary action.

Reasoning: She is not consciously aware that she is humming, which implies the behavior is beyond her control.

Analysis: The argument relies on a shaky bridge between awareness and responsibility. To weaken this, we should look for a way to hold her accountable regardless of her conscious state. Perhaps professional standards require players to control their physical habits, or maybe there are ways to stop 'involuntary' actions once they are pointed out. It's a bit like a sleepwalker claiming they aren't responsible for raiding the fridge; the lack of intent doesn't necessarily negate the consequences of the action.
