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.

Chesthetica, especially if running on multiple computers or operating system user accounts, is capable of generating far too many compositions than can be published in a timely fashion here. The newer ones will therefore only be published some time later. This is why the composition or generation date above does not match today's date. White has a bishop, a rook and a knight for Black's pawn. Why not time yourself how long it took you to solve this? Collectively, these puzzles are intended to cater to players of all levels.
