> These are surely not true when you're at a high level, but for most people it's the right focus. It is trivially true at all levels - anything that leads you to lose a game can be construed as a mistake, so if you make no mistakes and you lose then the game has been solved (which Chess has not been) or was unwinnable. The mistakes just get smaller and fewer and fewer people can recognise them.
