What we have here is a ‘KQRB vs krn’ five-move chess puzzle or problem (whichever you wish to call it) composed by Chesthetica using the approach known as the DSNS from the sub-field of AI, computational creativity. Depending on the type and complexity of the problem desired, a single instance of Chesthetica running on a desktop computer can probably generate anywhere between one and ten problems per hour.

Composing a chess puzzle or problem requires creativity and it’s not easy even for most humans. What was the machine ‘thinking’ when it came up with this? 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. So do check out some of the other problems. You can probably find something more to your taste.
