A newly published and original KRBPP vs kp #4 chess puzzle or problem (whichever you wish to call it) composed by the prototype computer program, Chesthetica, using the relatively new computational creativity approach called the 'DSNS'. 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.

A seemingly earlier version of Chesthetica on a problem composed later (based on the date and time stamp) simply means that version may have been running on a different computer or operating system user account. Chesthetica composes everything autonomously (no human intervention) and even chooses the main line of the solution to show you. Did you find this one interesting or have something else to say? Leave a comment below! Take some time to study the analysis and you might appreciate the puzzle a little more.
