Thinking about it analytically, the human+AI chess player cannot be dominated by an equivalent AI (since the human could always just play the move suggested by the engine.) In practice, people play correspondence chess for entertainment or for money, and the money is just payment for someone else’s entertainment. Therefore, chess will properly enter the AI era (post-cyborg) when correspondence chess becomes so boring and rote that players stop even bothering to play.
