Published online for the first time, consider this KRBNN vs krn three-move chess problem generated autonomously by the program, Chesthetica, using the relatively new computational creativity approach called the 'DSNS'. 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 8 pieces could have been taken from such a database.

If you notice an earlier version of Chesthetica listed with a newer problem, that simply means an earlier version may have been running on a different computer or OS user account. White is over a rook's worth in material but the precise win in this position still needs to be found. Why not time yourself how long it took you to solve this? Note that not all the chess problems are like this. They cover quite the spectrum of solving ability and there are thousands published already. Anyway, if standard chess isn't your thing, you might instead like SSCC.
