There's 113 positions.
I tried to set a difficulty (tag c1 : diff=1 to 10) for each positions.
This value is quite subjective, it's a mix between my human view and the time solution for engines.
I let SF analyze 1h per position (only 25 min for the 39 first position as they are easier) CPU= 1 cores Intel i7@4Ghz, results in next post. I have also several run on 6 cores (around 30 min).
I made a mistake or Arena have a bug with the "c1" (comment 1) tag. It was impossible to run automatic testig with this "c1" tag.
I saw a couple of new position this ways. I'll probably add them and release the official version of this set in 1 month.

Arena won't recognize the bm if there is no space after semi-colon.
The c is for comment, it is also best to enclose the value of comment 1 with double quotes. Especially when there are empty space in the comments like, c2 "King attack and passer"; Example,
Code: Select all
1R4bq/p1p3p1/2p3Pb/k1P4R/2P4P/p5P1/P7/1K6 w - - bm Ka1; c1 "diff=1";
I can help with the formatting if you need one.
Thanks for posting these difficult positions, I gained some rating points by closely examining the position, understanding its winning line, then check the engine codes if the feature to solve it, is there or not.
