Over the past several months, I have gone through the current Arasan test suite and removed some positions that seem too easy, and also added a bunch that are interesting and/or harder. Some of the latter have been posted here, but some have not. I've verified all the positions as best I can using multi-pv analysis. In some cases there is more than one good move, but the given bm scores significantly higher than other moves.
Current file is here:
https://www.arasanchess.org/arasan21-beta.epd
These are sort of in difficulty order: the ones towards the end of the set are generally more difficult.
I'd be interested in any feedback/corrections. I used Stockfish for verification, but results from other engines would be interesting.

Re: Arasan test suite - draft version
I ran the new positions with Stockfish_19060914 (6*4GHz), first column is 10 seconds per move and second column is 20 seconds per move.
The list is sorted on column1 then column2.
80 positions seem not so hard (for SF).

Hi Jon,jdart wrote: ↑Wed Jun 19, 2019 8:12 pm Over the past several months, I have gone through the current Arasan test suite and removed some positions that seem too easy, and also added a bunch that are interesting and/or harder. Some of the latter have been posted here, but some have not. I've verified all the positions as best I can using multi-pv analysis. In some cases there is more than one good move, but the given bm scores significantly higher than other moves.
Current file is here:

These are sort of in difficulty order: the ones towards the end of the set are generally more difficult.
I'd be interested in any feedback/corrections. I used Stockfish for verification, but results from other engines would be interesting.

Re: Arasan test suite - draft version
I removed positions found in less than 10 seconds, 2 times (and I hold all the AMs solutions).
It left 71 positions.
I ran this positions with the latest SF ( Stockfish_19062016 ) , 1 minute per position , 6*4 GHz.
Still 36 positions, not found each time under 1 minute.
Results table :
