Computer-Generated Chess Problem 02136

A new if not unique KQBBN vs kqb mate in 4 chess puzzle or problem (whichever you wish to call it) composed by the program, Chesthetica, using the DSNS computational creativity approach which doesn't use any kind of traditional AI. (Learn more about the DSNS here: https://arxiv.org/abs/1507.07058). The largest endgame tablebase in existence today is for 7 pieces (Lomonosov) which contains over 500 trillion positions, most of which have not been seen by human eyes. This problem with 8 pieces goes even beyond that and was therefore composed without any such help.

Chesthetica, especially if running on multiple computers or operating system user accounts, is capable of generating far too many compositions than can be published in a timely fashion here. The newer ones will therefore only be published some time later. This is why the composition date above does not match today's date. Remarkably, Chesthetica never composes duplicate problems using its DSNS technology. Solving chess puzzles like this is probably good for your health as it keeps your brain active. Nobody wants something like early-onset Alzheimer's.
