Computer-Generated Chess Problem 04117

in #chesslast year

Published online for the first time, consider this KRBNP vs kqnpp mate in five chess puzzle 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. This position contains a total of 10 pieces. The largest complete endgame tablebase in existence today is for seven pieces (containing over 500 trillion positions anyway) which means the problem could not have been taken from it regardless.

Sometimes an earlier version of Chesthetica is credited for a more recent problem because that version was still running on that computer at the time. White has a bishop and a rook for Black's pawn and queen. 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.
