Hi Adam,

Forgive me if I don't quite understand your problem.

You have a PGN file, a database of many PGN Fischer Randon games, and you are interested in knowing how often each side castles on the same side, on opposite sides, etc. Yes?

A year or two ago I wrote a little utility for myself called "PGN Cleanup" which, among other things, gives a bunch of statistics on the file it processes. And yes, one of those statistics are a few castling statistics.

For example, below is the partial output from a PGN file that I downloaded and then processed:


Win / Loss Statistics:
----------------------
Number of games White won: 20,306 (38.4%)
Number of games Black won: 15,628 (29.6%)
Number of draws: 16,924 (32.0%)

Castling Statistics:
--------------------
White castled Kingside and Black castled Kingside: 35,932 (68.0%)
White castled Kingside and Black castled Queenside: 1,878 (3.6%)
White castled Kingside and Black did not castle: 3,920 (7.4%)

White castled Queenside and Black castled Kingside: 3,566 (6.7%)
White castled Queenside and Black castled Queenside: 1,020 (1.9%)
White castled Queenside and Black did not castle: 1,504 (2.8%)

White did not castle and Black castled Kingside: 2,694 (5.1%)
White did not castle and Black castled Queenside: 568 (1.1%)
Neither player castled: 1,774 (3.4%)



Even though your file is a file of FR games, with a Shredder FEN tag to distinguish the opening position, the castling notation within the PGN remains the same, does it not? O-O for Kingside Castling and O-O-O for Queenside castling? If so, my program wouldn't care if the games were FR games or normal games... it would generate a similar set of statistics for your file.
