Published online for the first time, consider this KRRN vs kppp chess puzzle or problem (whichever you wish to call it) composed by the prototype computer program, Chesthetica, using the approach known as the DSNS from the sub-field of AI, computational creativity. The program can compose problems that may otherwise take decades, centuries or even longer for human composers to think of, or to arise in a real game. There is no known limit to the quantity or type of compositions that can be generated.
Humans have been composing original chess problems for over a thousand years. Now a computer can do it too. Okay, let me think for a minute if there's anything else to say here. If this one is too easy or too difficult for you, try out some of the others. 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.
