A tool to search for certain moves played Is there a tool to display how many times a certain move has been played?
Note that I do not mean openings, I mean specific moves. Moves that I am looking for would be castling with checkmate or underpromotion to a knight with checkmate, and similar things. Is there a tool available to search for something like that?
