A newly published and original KBNN vs krppp mate in four chess puzzle or problem (whichever you wish to call it) composed by the prototype computer program, Chesthetica, using the DSNS computational creativity approach which doesn't use any kind of traditional AI. There is also no proven limit to the quantity or type of legal compositions that can be automatically generated. The largest complete endgame tablebase in existence today is for seven pieces (Lomonosov) which contains over 500 trillion positions, most of which have not been seen by human eyes. This problem with nine pieces goes even beyond that.

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. Do share and try out some of the others too. Note that not all the chess problems are like this. They cover quite the spectrum of solving ability and there are thousands published already.
