Consider this 'KRRRN vs krbn' #5 chess construct composed autonomously by the program, Chesthetica, using the computational creativity approach which doesn't use any kind of traditional AI or even deep learning. There is also no proven limit to the quantity or type of legal compositions that can be automatically generated. The position below contains 9 pieces which means it simply could not have been derived even from an existing endgame tablebase which is presently limited to 7 pieces.
White to Play and Mate in 5
Chesthetica v11.20 (Selangor, Malaysia)

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. White is over a rook's worth in material but the precise win in this position still needs to be found. Try to solve this puzzle. Do try some of the others in the series as well before you go. 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.
