It's 5.00 (October 15, 1999). Is there some kind of official >opening book for GNUChess that I'm missing? I'm not exactly sure if there is a book for 5.00 that comes with Winboard or not, I think that when Tim first released it that it didn't work for some reason, but I do know that there is a pgn intended for the book that comes along with the source. I lost track of where I got my book for it by now. I'm pretty sure that Dann Corbit has an opning book for his version, but I think he used his own collection og pgn for it, but I'm not really sure if that matters all that much because I have doubts that any serious thought went into the book for that version. I don't think it's a very polished program yet, but the code is a lot cooler, and it probably has a great deal of potential in it, where as the last version was just a confusing mess IMO. > >>>I didn't expect it to match Crafty, but barely managing one draw >>>in 38 games was somewhat disappointing.

I don't know about the licensing on Phalanx, but that's a great program, very slick program. Not as strong as Crafty by a long stretch, but a lot stronger than GNUchess. Pete
