I >guarantee you will see some fireworks. Note that I never use more than 100 sort files with enormous. I made the blocksize way bigger. I think it didn't even break 60 last time I built it. When I use my normal book create enormous.pgn 60 5 50, it has no problems at all. I would _not_ create a book from that pgn using 999 1 as options, as there are plenty of really ugly games that I wouldn't want a computer to even think of following. :) > >>However, you don't put the book create command in the crafty.rc file... that is >>the wrong way to do it as it might well be attempted before things are set up >>right. >> >>Start crafty in a dos window and type the 'book create' command....
