Here is a 'KRNPP vs kqbp' four-move chess problem generated by a computer using the DSNS computational creativity approach which doesn't use any kind of traditional AI. You can learn more about the DSNS here. This position contains a total of 9 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.

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. Remarkably, Chesthetica never composes duplicate problems using its DSNS technology. Try to solve this puzzle. Do try some of the others in the series as well before you go. Solving chess puzzles like this can also help improve your game.
