What we have here is a 'KRPP vs kp' mate in four chess problem generated autonomously by the program, Chesthetica, using the Digital Synaptic Neural Substrate AI computational creativity method. Chesthetica can compose problems that might otherwise take centuries or longer for human composers to think of, so you may enjoy them right now. 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 (e.g., composing something original using only a rook vs. five pawns).

Some of the earliest chess problems by humans are over 10 centuries old but original ones by computer are very recent. White is over a rook's worth in material but the precise win in this position still needs to be found. 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. Therefore, do consider some of the other problems available. You can probably find something more to your taste.
