As an aside, I have made a program to find pretty mates within the thousands of games I’ve been having my computer play to research the Schoolbook opening. What the program does is look at games; when there is a position where one side thought they were even or ahead but the other side suddenly found a mating combination, it notes the game.

These types of positions are actually quite rare; in the 5,000 games or so I have had my computer play to research Schoolbook, only 24 mates of this nature were found; a mate like this happens about once every 200 games.

These mates (in addition to the script that data-mines the .pgn files to find these kinds of positions) can be found here:
