Computer-Generated Chess Problem 02859
Now, this is a 'KQRBPP vs kqrrp' mate in 3 chess problem generated autonomously by Chesthetica using the relatively new computational creativity approach called the 'DSNS'. Chesthetica is able to generate three-movers, four-moves, five-movers and study-like constructs and also compose problems using specific pieces types fed into it (such as using only a queen vs. rook and knight). Read more about it on ChessBase. 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 11 pieces goes even beyond that and was therefore composed without any such help whatsoever.

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. Everything composed by Chesthetica is original. Try to solve this as quickly as you can. If you like it, please share with others. Take some time to study the analysis and you might appreciate the puzzle a little more.
