Computer-Generated Chess Problem 03599

A 'KRRBB vs knpppp' mate in four chess puzzle 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). The largest complete endgame tablebase in existence today is for seven pieces (Lomonosov) which contains over 500 trillion positions, most of which have not been seen by human eyes. This problem with 11 pieces goes even beyond that.

These chess puzzles are published in order based on the composition date and time stamp above. Due to the sheer volume of compositions generated, the latest ones may therefore only be published later on. White is over a rook's worth in material but the precise win in this position still needs to be found. Did you find this one interesting or have something else to say? Leave a comment below! Feel free to copy the position into a chess engine and potentially discover even more variations. If you're bored of standard chess, though, why not try this?
