Here is a 'KQRB vs krrn' mate in 3 chess problem generated by Chesthetica using the DSNS computational creativity approach which doesn't use any kind of traditional AI. Chesthetica has the creative ability to compose positions that may otherwise take centuries to arise in an actual game, if ever. There is also no proven limit to the quantity or type of legal compositions that can be automatically generated. Any chess position over 7 pieces could not possibly have been derived from an endgame tablebase which today is limited to 7 pieces.
