The Greatest Chess Player Alive Almost Resigned on Saturday. The Room Was Too Hot.

"It's fucking one million degrees in the playing hall," he told TV 2, as reported by journalist Tarjei J. Svensen. "I didn't feel like I had enough oxygen getting to my head. I considered resigning just because I was so damn fed up."
He drew. Vincent Keymer — 20 years old, outplayed him for most of the game, came within one move of the biggest upset of the year — emerged from the same airless room, sat in front of the same cameras, and described the game as "very complex and interesting."
Same room. Same air. Different expectations from the organizers.
Twitter filed Carlsen's remarks under "decline." This is wrong. What Carlsen has — after fifteen years, five world titles, and enough ranking points to survive a press conference — is the rarest commodity in professional chess: the freedom to mention that the building is on fire while everyone else files out calmly and tells reporters they enjoyed the warmth.
He didn't almost lose because he's declining.
He almost lost because the room had no oxygen and he's the only person in chess allowed to say so.
Keymer, for his part, is still being interesting and complex. And probably exhausted from the heat as well.
