Re: Syzygy Problem

So the Fritz GUI is buggy.

Either let the engines, not the GUI, play the TB moves, or let the GUI immediately adjudicate the game once a TB position is reached. It makes no sense to let the GUI take over and mess up the game.

Re: Suicide chess tablebases (stalemated player wins)

I have also added a generator for atomic chess just in case someone is interested. Hi, does the TB generator here https://github.com/syzygy1/tb for Atomic Chess support 7 men generation for Atomic Chess? I would like to generate certain 7 men TBS if possible so i wonder if it supports them. I think...

This is really not AI but instead artificial stupidity. The progress you've made in about 8 months in this thread disproves the existence of HI.

Re: Include 4men syzygy in an engine

With this changes the probing code gives wrong results, what have I missed? Are there other parts of code to change? Do you have a version of your program that works without the changes you made (so that mmaps() the files into memory when needed)? If you do, then it should be relatively easy to fin...

Re: Sysygy Shatranj?

Would it be trivial to adapt the Syzygy EGT generator for Shatranj? Or would it be easier to just write a dedicated generator for that? I am only interested in the WDL statistics of a few specific 6-men end-games (KRFE-KR and KFF-KFE). I don't need the tables itself, so I don't care about compressi...

Re: longest 6-man EGTB win

Anyone have a list of positions of the longest 6-man EGTB wins that meet 50 move rule requirements? I.E. no cursed wins allowed I think to do this accurately, you must have the complete Lomonosov files. They have distance to mate. But they don't take into account the 50-move rule. Whenever they sho...

Re: Another take on DTS?

Hello everyone, I am surprised to see currently so few interests in Dynamic Tree Splitting in comparison with Lazy SMP. Is it because DTS seems to be adapted to multiprocessors or large-scale network while Lazy SMP is for multithreading? Is there any scientific or empirical comparison between the t...

Re: Syzygy DTZ data explaination?

Can you help me confirm what I have just guessed for the above case (position K7/8/8/8/8/2R5/8/7k b - - 0 1) 1) All raw data DTZ of all three black-King moves (Kg1, Kg2, Kh2) has the same rank -1000 (losses with little chance to reach the 50-move rule) Your position has three moves, all losing with...
