A new if not unique KRBNNPPPP vs kqrrbb chess problem generated autonomously by the prototype computer 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 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 15 pieces could have been taken from such a database.

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 actually has less material than Black yet still wins. The white army is down by about 7 (Shannon) pawn units in value. Hint: there might be a pawn promotion involved. Try to solve this as quickly as you can.
