Computer-Generated Chess Problem 02490
This is an original 'KRNPP vs kqr' mate in 3 chess puzzle or problem (whichever you wish to call it) composed by Chesthetica using the relatively new computational creativity approach called the 'DSNS'. You can learn more about the DSNS here. 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. Try to solve this puzzle. Do try some of the others in the series as well before you go. Collectively, these puzzles are intended to cater to players of all levels.
