Computer-Generated Chess Problem 02371
An original 'KQRRBN vs krbnpp' chess puzzle created by a computer program, Chesthetica, using the DSNS computational creativity approach which doesn't use any kind of traditional AI. 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 position below contains 12 pieces which means it simply could not have been derived even from an existing endgame tablebase which is presently limited to 7 pieces.

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. White has a decisive material advantage in this position but the winning sequence may not be immediately clear. 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 be good for your health as it keeps your brain active. It may even delay or prevent dementia.
