Consider this 'KRBBNP vs kqbn' #3 chess problem generated by a computer using the relatively new computational creativity approach called the 'DSNS'. You can learn more about the DSNS here. The largest (Lomonosov) tablebase today is for 7 pieces which contains over 500 trillion positions. With each additional piece, the number of possible positions increases exponentially. It is therefore impossible that this problem with 10 pieces could have been taken from such a database.
