Re: Syzygy tbs bug

Re: Fritz 17

I buy chess engines often just to support the authors.
A pretty harmless hobby.
:wink:
Edit: my buying chess hardware is criminally insane.

Re: Space/Time Tradeoff in year 2020+: What can the community do with 20TB+ Hard Drives?

Imagine 1000 machines analyzing different EPD positions, charging their hash tables along the way.
The database just of the PV nodes can get pretty big.

Re: Official Release of Ethereal 11.75, supporting MultiPV

I suggest adding the bottom lines as shown in file uci.c: int main(int argc, char **argv) { Board board; char str[8192]; Thread *threads; pthread_t pthreadsgo; UCIGoStruct uciGoStruct; int chess960 = 0; int multiPV = 1; setvbuf(stdin, NULL, _IONBF, 0); setvbuf(stdout, NULL, _IONBF, 0); fflush(NULL);...

Re: There are NOT any Books on FRC Opening.............

The inventors imagined that FRC would favor humans, giving them a better chance against the machine. That's not true. They (or he, Fischer) didn't care about machines. It's certainly not true (of non-inventors) now. Top players have no interest in playing machines. "I don't know when, but I think w...

Re: There are NOT any Books on FRC Opening.............

Before long, there will be named openings for FRC, just like regular chess. The inventors imagined that FRC would favor humans, giving them a better chance against the machine. I think the opposite is true. The existing data could already be used to compile openings. Simple statistical evaluation ba...

Re: Testposition

Without a doubt, Nh4 is the best move. I will have a better answer in a while, but for now: 47 +1.09 29:34 17629M Nh4 Kh7 Bxh5 Rh8 Qg3 Kg8 Bxg6 fxg6 Re3 Bd7 Ng2 Kf7 Nf4 gxf6 gxf6 Rh6 Qg4 Qh8 Rg3 Qh7 Nh3 Kg8 Ng5 Qh8 h3 Rh4 Qf3 a5 Rf1 Bd8 Qe3 Rh5 Qe2 Kf8 Qd2 Qh6 f4 Qh8 b3 Bxf6 exf6 Qxf6 Nf3 Qf5 Ne5 Be...
