Computer-Generated Chess Problem 02790

Take a look at this 'KQRBNN vs krbnpp' mate in 5 chess puzzle or problem (whichever you wish to call it) composed 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 12 pieces which means it simply could not have been derived even from an existing endgame tablebase which is presently limited to 7 pieces.

These chess puzzles are published in order based on the composition date and time stamp above. Due to the sheer volume of compositions generated, the latest ones may therefore only be published later on. 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. 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.
