Thanks ! I made the corrections in the files.Dann Corbit wrote:The following positions contain frivolous ep markers:

Better as:

r1b1k1r1/1p2np1p/p1n1pQp1/3p4/3NPP2/P2RB3/2PK2PP/q4B1R w q -
8/pp3p1k/6pp/7P/P5P1/3K4/1PP5/8 b - -
So as not to waste database space and effort solving problems that are already solved.

Re: Hard talkchess 2018 set - work in progress
After the first version sorted out, it remains 89 regular positions (as Candidates II) and 18 special positions.
I ran this 89 positions : Stockfish_180412_x64_modern, 5 runs, 10 min per positions, 6*4GHz, 6 pieces Syzygy.
Here are the results and after that, the 89 positions.
I still have doubt about 2 to 5 positions. I'll post later.
The 89 positions :

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Hard talkchess 2018 set - work in progress
I ran the same 89 positions with Houdini 1.5, 4 runs, 10 min per positions, 6*4GHz.Vinvin wrote:After the first version sorted out, it remains 89 regular positions (as Candidates II) and 18 special positions.
I ran this 89 positions : Stockfish_180412_x64_modern, 5 runs, 10 min per positions, 6*4GHz, 6 pieces Syzygy.
Here are the results and after that, the 89 positions.
I still have doubt about 2 to 5 positions. I'll post later.

A few others I have collected recently:

Not sure if these qualify as "hard".

Re: Hard talkchess 2018 set - work in progress
I'm interrested in these 18 special positions you mentioned above.Vinvin wrote: ↑Mon Apr 23, 2018 11:24 pm After the first version sorted out, it remains 89 regular positions (as Candidates II) and 18 special positions.
I ran this 89 positions : Stockfish_180412_x64_modern, 5 runs, 10 min per positions, 6*4GHz, 6 pieces Syzygy.
Here are the results and after that, the 89 positions.
I still have doubt about 2 to 5 positions. I'll post later.
