Peter,

Thank your offer to host my pgn file on crafty-chess.com.

I'm in the processing of sending you my pgn file (11M zipped) via dial-up. There
are about 49K games in the book. It is named normbk00.pgn.  I recommend that
users use a setting of 6+ occurrences when creating books for
engines/interfaces. Anything less than 6 runs a serious risk of using opening
moves that are speculative.

I will send you an update about every 3 months. In which case I will increment
the last 2 digits on the file name. The updates will reflect additional games
that were recently played and reported in TWIC or elsewhere.

Norm
