Here is a new 'KQBBPPP vs kbbnpp' mate in 4 chess construct composed autonomously by a computer program, Chesthetica, using the 'Digital Synaptic Neural Substrate' computational creativity approach which does not use any kind of deep learning. 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 13 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. Get a glimpse into the 'mind' of a computer composer. Do share and try out some of the others too. Take some time to study the analysis and you might appreciate the puzzle a little more. If you're bored of standard chess, though, why not try this?
