Computer-Generated Chess Problem 02671
What we have here is a 'KQRRN vs knpp' mate in 3 chess construct composed autonomously by Chesthetica using the relatively new computational creativity approach called the 'DSNS'. Chesthetica is able to generate various types of mates and study-like constructs and also compose problems using specific combinations of pieces fed into it (such as using only a queen vs. rook and knight). Learn more about it on ChessBase. 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.

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. White has a decisive material advantage in this position but the winning sequence may not be immediately clear. Leave a comment below, if you like. Some of these problems may be trivial for you, especially if you're a club or master player but bear in mind that chess lovers can be found at all levels of play. So do check out some of the other problems. You can probably find something more to your taste.
