The speaker expects current systems to fail on many chess variants and problems, and says he can devise tic-tac-toe variants such as a five-by-five board where wins are allowed only on the edges.

“Chess actually has lots of variations or chess problems and things like that that these systems won't be able to do. I'll probably be able to come up with variations on tic-tac-toe. So five by five board,”

“but you can only win on the edges.”
