Consider this 'KQRB vs kqbnp' four-move chess problem generated by a computer 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. Incidentally, this is also a 'mutual mate' problem (more generally known as a 'duplex'). That means if Black were to play, it is also a forced mate in the same number of moves. They are quite rare in direct mates. The solvability estimate applies only to White's solution. Read more about mutual mates here. Depending on the type and complexity of the problem desired, a single instance of Chesthetica running on a desktop computer can probably generate anywhere between one and ten problems per hour. The largest complete endgame tablebase in existence today is for seven pieces (Lomonosov) which contains over 500 trillion positions, most of which have not and never will be seen by human eyes. This problem with nine pieces goes even beyond that.

Chess puzzles are ancient. Some are over a thousand years old but only in the 21st century have computers been able to compose original ones on their own like humans can. White has a rook for Black's pawn and knight. Do share and try out some of the others too. Solving chess puzzles like this is probably good for your health as it keeps your brain active. Nobody wants something like early-onset Alzheimer's.
