KNNN vs K : how come Stockfish cannot find the mate in 17?

To make a long story short, I have posted an entry on the subject on my blog. Am I missing something here? Stockfish seems to be unable to find this mate in 17 and alternates between different results even though its search deep enough to have seen the mate in 17! My blog entry: https://endormitoire...

Kasparov vs The World

I came across the 1999 game Kasparov vs The World and was curious as to what is the definitive answer to all the proposed solutions for the position after move 58.g6 8/6K1/6P1/3p4/3Q4/5q2/8/1k6 b - - 0 58 At the time, Kasparov published a 25-pages analysis while Irina Krush argued that 58...Qf5 gave...

I can't load the file with Chessbase 14, but with Aquarium 2017.
Am I right, that there are games only till 2008?
I am curious. What is the error you encounter with Chessbase 14?

Re: The first release of the CGR games database

2) Because they take an awful lot of space. You could easily double the size of the files. 3) I was thinking of providing the WhiteIsComp/BlackIsComp tag (when it is not already there) in a future release so you could filter out games played by computers. As I said, I don't want to impose my choice...

[/quote] I'v tried to unzip it on Ubuntu 16.04 without success. Finally uncompressed on Windows, but it needed huge amount of time.

Re: The first release of the CGR games database

You claim the (wh) and (bl) tags are useless and idiotic on the basis of redundancy. If it were just to indicate which side he is playing I would agree with you. However...

Re: The first release of the CGR games database

It occupies 100 MB less space than the zipped PGN file. As for the database: nice stuff. Thank you. Just for your information: ...
