Computer-Generated Chess Problem 02115
Here is a 'KQRB vs kqrnp' mate in 4 chess puzzle or problem (whichever you wish to call it) composed by a computer program, Chesthetica, using the DSNS computational creativity approach which doesn't use any kind of traditional AI. Chesthetica has the creative ability to compose positions that may otherwise take centuries to arise in an actual game, if ever. The largest endgame tablebase in existence today is for 7 pieces (Lomonosov) which contains over 500 trillion positions, most of which have not and never will be seen by human eyes. This problem with 9 pieces goes even beyond that and was therefore composed without any such help whatsoever.

White actually has less material than Black. The white army is down by about 1 (Shannon) pawn units in value. Do share and try out some of the others too. As a whole, these problems are intended to cater to players of all skill levels.
