A new if not unique KQRBN vs kqpp #3 chess construct composed autonomously by a computer program, Chesthetica, using the 'DSNS' computational creativity approach which does not use any kind of machine or deep learning. The largest (Lomonosov) tablebase today is for 7 pieces which contains over 500 trillion positions. With each additional piece, the number of possible positions increases exponentially. It is therefore impossible that this problem with 9 pieces could have been taken from such a database.

If you notice any version of Chesthetica 'skipped' from one problem to the next, that simply means additional (minor) changes were made to the program before it was set to run again. White is over a rook's worth in material but the precise win in this position still needs to be found. Leave a comment below, if you like. 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. Anyway, if standard chess isn't your thing, you might instead like SSCC.
