Related question: Has anyone ever experimented with taking a really strong engine for one of these games and then simulating the sort of mistakes that humans make (overlooking certain positions, looking ahead fewer steps, etc) to try and simulate different skill levels of opponents?<p>I don&#x27;t play Go, but I dabbled a little bit in Chess, and it seems like the engines with &quot;difficulty settings&quot; don&#x27;t really make the sort of mistakes that humans make. They can, of course, just over-prune the look-ahead tree, but that&#x27;s not how the human brain works.
