Re: Official Release of Ethereal 11.75, supporting MultiPV

It's probably better if you could set the perfect setup for Ethereal 11.75 under Linux/cutechess and then if it's running perfect, my "obviously bad setup" is causing the problem. Why should I? I'm not interested in testing Ethereal like you seem not interested in understanding what processor cores...

Re: Minic raw speed

Minic is sorting all moves as soon as TT move is not a beta cut-off You could benchmark how often your first move cuts off if it isn't a TT hit, this will probably be something like 50-70%. Means, in all those cases, sorting the full move list is unnecessary because you're only going to use the top...

Re: PGN standard, its improvement and standardization

Due to the fact that we have a huge number of different chess shells, I believe that it is necessary to create a new format for PGN files, which will standardize computer position evals, its analysis and additional data. With a single format, it will be much more convenient to use one PGN file in v...

Re: Wasp 3.75 by John Stanback released ...

I made a change where if the first move at the root fails low several times (score has dropped about 2 pawns or more) then I accept that score for the first move, set a flag, and search the remaining moves to see if one of them is better. If not, then I repeat the iteration. Looks more like a hack ...

Re: Linux flavors - opinions

Ubuntu has gcc 7.0 by default which is fine, but CentOS 7 on the other hand comes with 4.8.5 which is a royal pain. It can't compile my fortran 2008 and c++11 codes most of the time. yum-config-manager --enable rhel-server-rhscl-7-rpms \ && yum -y install devtoolset-7-gcc devtoolset-7-gcc-c++ devto...

Re: FRC / Chess960 -- Some Lessons I Learned

#1 Move Encoding In this process I think I came across the answer to the question "Why does Stockfish encode castle moves as King captures Rook". I chose a different route, but I'll write a bit about both. The benefit, or the reason, that Stockfish encodes using KxR is because at many points in the...
