Re: why did they destroy stockfish in finding mates

I think this is actually a very, very good idea. Ankan's move generator is absurdly fast. So couple this move generator to and and/or depth-first proof search. I have a feeling it might be scary good at mate solving. Scary Good :shock: Right, but while basic CUDA programming is not too hard, it tak...

Re: why did they destroy stockfish in finding mates

I used the latest version of stockfish and it was very slow in finding mate.... Does the fact that a strong program can inadvertently prune some mating patterns out of its search tree leave an opening for humans? What other patterns might strong programs be missing? Maybe such opportunities are too...

Re: TalkChess Is Back

Hello All, We all know that TalkChess was not working for a few days. But, why did it fail? Was it "hacked"? Why the redirection to "Off-the-air"? What protocol is now in place to ensure that doesn't recur? Thanks in advance, -Steve- According to Quentin, unexpectedly high demand for chess-related ...

Re: We have a chess queen, but do you know the queen of chess?

About the mate announcements I doubt if all of them are correct. I found no proof for the mate in 11 claim and I am also practically sure it was impossible without a computer to write a tree that proves the mate. If somebody has not mate claim but proof that there is a forced mate with the relevant...

Re: Calculating Tactics -- Don't Look

I was watching Hikaru Nakamura play blitz on a recording of his livestream. When calculating exchange tactics, he looks up at the ceiling, taking his eyes off the screen. Otherwise, he looks at the screen to evaluate the position. I've not seen any other live streamer do that, e.g. IM Rosen. Did yo...

Re: A Book For a Vintage Program

I'm looking for an opening book for a vintage computer program from the late 1970s. I'm guessing this program has not played any public games since 1978. It will likely not search deeper than 9 plies at human tournament time controls. The program will not be a giant killer but it might be a novelty...

Re: A Book For a Vintage Program

Hello! I don't know exactly what kind of book you are looking for, but for me I was glad when I discovered that I could use pgn-extract to build books in what I called "TSCP format" (maybe the good format for a vintage program), from pgn files. So I downloaded collections of grandmasters games and,...

Re: A Book For a Vintage Program

IMO the book should be kind of mirror of the playing style of the engine. If it plays like Petrosian I would not bring aggressive openings into the book. If the engine plays Like tal it would be nice to bring open positions into the book. If it plays very nimzowitch.... The engine must come out of ...
