> Carlsen is known for his ability to beat his opponents at chess. Has nothing to do with mental fortitude. You're choosing to ignore the entire argument instead of addressing it. When you say "ability to beat his opponent at chess" that includes the mental fortitude (also emotional stability, ability to perform consistently over long matches etc) The point is that after game 6 Ian's performance was far below his actual chess ability. So we look to psychology to explain that difference. Saying stuff like "he performed at that level so that's his ability" doesn't get anyone anywhere.
