Published online for the first time, consider this KRBBN vs krn four-move chess puzzle or problem (whichever you wish to call it) composed by a computer program, Chesthetica, using the DSNS computational creativity approach which doesn't use any kind of traditional AI. Chesthetica has the creative ability to compose positions that may otherwise take centuries to arise in an actual game, if ever. You can learn more about the DSNS here. The largest endgame tablebase in existence today is for 7 pieces (Lomonosov) which contains over 500 trillion positions, most of which have not and never will be seen by human eyes. This problem with 8 pieces goes even beyond that and was therefore composed without any such help whatsoever.

The chess problems are published chronologically based on the composition date and time. However, later compositions may have an earlier version of Chesthetica listed because more than one computer (not all running the same version of the program) is used. 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. Over time, the tactics you see in these puzzles will help you improve your game. Anyway, if standard chess isn't your thing, you might instead like SSCC.
