A 'KBNP vs kbppp' mate in four chess puzzle or problem (whichever you wish to call it) composed by a computer program, Chesthetica, using the 'digital synaptic neural substrate' (DSNS) computational creativity approach. It doesn't use endgame tablebases, deep learning or any kind of traditional artificial intelligence (AI). You can learn more about the DSNS here. The largest complete endgame tablebase in existence today is for seven pieces (Lomonosov) which contains over 500 trillion positions, most of which have not and never will be seen by human eyes. This problem with nine pieces goes even beyond that.

Even with the same version number, each copy of Chesthetica 'evolves' and may perform somewhat differently over time. White has a slight material advantage over Black.
