Contemplate this 'KQN vs krrpp' #3 chess puzzle or problem (whichever you wish to call it) composed by a computer program, Chesthetica, using the relatively new computational creativity approach called the 'DSNS'. 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.
If you notice an earlier version of Chesthetica listed with a newer problem, that simply means an earlier version may have been running on a different computer or OS user account. Chesthetica composes everything autonomously (no human intervention) and even chooses the main line of the solution to show you. Why not time yourself how long it took you to solve this? Collectively, these puzzles are intended to cater to players of all levels. Anyway, if standard chess isn't your thing, you might instead like SSCC.
