Computer-Generated Chess Problem 01940
Take a look at this 'KRBNN vs krrp' mate in 4 chess puzzle created by Chesthetica using the relatively new computational creativity approach called the 'DSNS'. Chesthetica is capable of composing positions that may otherwise take centuries or longer to arise in an actual game; so you can enjoy them right now instead. 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.

A seemingly earlier version of Chesthetica on a problem composed later (based on the date and time stamp) simply means that version may have been running on a different computer or operating system user account. Chesthetica composes only unique or new constructs. If you have seen it before, cite the source and comment below because it is purely coincidental. Do share and try out some of the others too. Feel free to copy the position into a chess engine and discover even more variations of the solution. Anyway, if standard chess isn't your thing, you might instead like SSCC.
