Re: Advice on book building

I just want to add a few suggestions on filtering pgn games before using them to build a book. 1. Limit games to quality players in quality events. For example, minimum elo 2300+, no exhibitions. 2. Limit games to comparable opponents. For example, elo difference could have a maximum of 100. 3. Do n...

Re: Use the crisis to solve crisis

Do NOT be discouraged if you do not have a GPU computer. FAH accepts CPU based computers. I have 3 CPU-based boxes connected online to them - all are Intel 5's, 2 have 4 cpu and 1 has 6 cpu. The setup asks for you to choose between low/medium/high. High uses all cpus, Medium uses 1 less cpu than hig...

Re: Popular opening books

Without changing any data, I made an edited version of the popbooks files. I combined the 3 files. I removed most of the opcodes, only keeping ce and pv. I re-ordered the records by descending ce value. I inserted id's. And then I made 2 "pgn" versions, one with the pv moves, and one without. http:/...

Alan Turing (father of computer chess)

The times, they are a-changing. Computer pioneer and war hero Alan Turing getting some well-deserved recognition. A movie, an apology, now this.

Re: Powerbook 2019 (ctg)

Did the computer engines that you used to make this book move entirely on their own, or they did they use opening books? If so, were those opening books based on human games?

Re: Polyglot extension tool

Hi thanks ED, that helps a lot. I don't know how many positions there are in the bin book, how can I know this? If I export the bin book to pgn with Lucas Chess I get 5000 different opening lines. (5000 games). How can I split the epd file in 5 parts? Is there some software to do that? Or do I have...
