A: All chess puzzle solutions are automatically verified by the software to be correct and complete. Please select "Options" -> "All moves graph" in the bottom right corner of the chess puzzle window to get the complete listing of all moves for the correct solution.
Please note that we do not automatically verify that the current solution is the absolute shortest/fastest, so it is still possible that there is another solution in a fewer moves. If you think you have found an alternative or shorter solution, please enter it via "Options" -> "Another solution". You would have to provide moves that lead to a checkmate, and a virtual opponent will automatically iterate through all possible responses, to prove that your solution is complete.
