A newly published and original KQRBBNN vs kqrbn mate in four chess puzzle or problem (whichever you wish to call it) composed by a computer using the DSNS computational creativity method. It does not use endgame tablebases, artificial neural networks, machine learning or any kind of typical AI. There is no known limit to the quantity or type of compositions that can be generated. This position contains a total of 12 pieces. The largest complete endgame tablebase in existence today is for seven pieces (containing over 500 trillion positions anyway) which means the problem could not have been taken from it regardless.
White to Play and Mate in 4

Chesthetica, especially if running on multiple computers or operating system user accounts, is capable of generating far too many compositions than can be published in a timely fashion here. The newer ones will therefore only be published some time later. This is why the composition or generation date above does not match today's date. White is ahead by a knight and a bishop. Did you find this one interesting or have something else to say? Leave a comment below! 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. Therefore, do consider some of the other problems available. You can probably find something more to your taste. If you'd like to learn something interesting about computer chess problem composition, consider this.
