Body: <p>I know this type of question has been asked a few times but each of the puzzles in the answers are solved by engines. For example Plaskett’s puzzle and other common ones such as Mitrofanov deflection and Mario Matous’ mate in 13 can be seen by matefinders easily. Are there any puzzles that truly stump engines?</p>
