Contemplate this 'KQBBNPPP vs kqbnnppp' study-like construct or chess problem generated autonomously by a computer 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. You can learn more about the DSNS here. Any chess position over 7 pieces could not possibly have been derived from an endgame tablebase which today is limited to 7 pieces. Any analysis shown for this study could be flawed as chess engines may change their recommendations given more time. The first or key move, at least, is probably right.
