La difesa di Lužin

The way Luzhin's obsession with chess seems to mirror his psychological decline is fascinating. What do you think Nabokov was saying about the link between intellect and madness?

The story becomes more introspective and tense here, but I wondered if Nabokov was emphasizing Luzhin's internal chaos over external action. Was that effective for others?

Chess isn't just a backdrop; it feels integral to the character's psyche. I'm curious whether Nabokov had personal experience or was making a broader statement about obsession.
