An original 'KQRNN vs kqrbbn' mate in 5 chess problem generated autonomously by Chesthetica using the fairly 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. Any chess position with this many pieces could not possibly have been obtained from known endgame databases. Chesthetica is therefore the real McCoy.

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. Over time, the tactics you see in these puzzles will help you improve your game.
