What we have here is a 'KRRNN vs kpp' four-move chess puzzle or problem (whichever you wish to call it) composed by the program, Chesthetica, using the relatively new computational creativity approach called the 'DSNS'. There is no known limit to the quantity or type of compositions that can be generated. This position contains a total of 8 pieces. The largest endgame tablebase in existence today is for 7 pieces (containing over 500 trillion positions anyway) which means the problem could not have been taken from it regardless.

If you notice any version of Chesthetica 'skipped' from one problem to the next, that simply means additional (minor) changes were made to the program before it was set to run again. Get a glimpse into the 'mind' of a computer composer. Try to solve this as quickly as you can. If you like it, please share with your friends. As a whole, these problems are intended to cater to players of all skill levels.
