Here is a new 'KRRB vs kppp' mate in four chess puzzle by the program, Chesthetica, using the approach known as the DSNS from the sub-field of AI, computational creativity. Chesthetica is able to generate mates in two, mates in three, mates in four, mates in five, study-like constructs and also compose problems using specific combinations of pieces fed into it (e.g., composing something original using only a rook vs. five pawns). Read more about it on ChessBase. The largest complete (Lomonosov) tablebase today is for seven pieces which contains over 500 trillion positions. With each additional piece, the number of possible positions increases exponentially. It is therefore unlikely that this problem with eight pieces could have been taken from such a database.

Chess puzzles are ancient. Some are over a thousand years old but only in the 21st century have computers been able to compose original ones on their own like humans can. White has two rooks and a bishop for Black's three pawns. Do you think you could have composed something better with these pieces? Share in the comments and let us know how long it took you. 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.
