True true true, but what's the relevance of all this? >>You guys are claiming it is a big hassle to write all-new basic book code. >>I find that claim ludicrous. > >I find that it took me at least a year of off and on work. Learning. >Format. You didn't spend a year only writing book code. I could see how a lot of thought and experimenting have gone into making the book builder both fast and compact (I think Crafties is one of the best there) and how to get learning to work well. But learning isn't an issue here. Neither are getting the books fast and compact - this isn't for a version that gets distributed anyway. >Choosing book lines (the ChessBase GUI does this also).

My "select a book move" code is >complicated enough, not even considering the learning issues... I've seen it. It's heavily catered towards taking care of itself, hence also the complex learning. Nothing of that sorts is needed for an 9 game tournament. My own (new) book code took a total of 2 days to write, plus another day for tuning learning and move selection. (That's excluding the code that reads and parses PGN/SAN...add another 2-3 for that) It's not as fast as Crafties and certainly not as compact, but it has working learning (again not as complex as crafties, but from what I see it works well enough), it can read PGN, text-based books, Fritz books, the whole shebang. -- GCP
