Some I have collected recently. Not verified at deep time control. May be considered not hard enough:

For SF10, 10 positions are easy, 1 is middle-hard (#12) and 4 are a bit hard.

#4 r1r3k1/1q1bbpp1/1p2p2p/2npP3/3B1PN1/p1P1QR2/PP2B1PP/3R2K1 w - - bm Rh3; c0 "BlackDemon-Arasan, FICS 2018";
b3 is very close to Rh3 and should be consider as a good move :

Nice position. Bxc6 is superior but Bb5 and Be2 seems winning also.

Nice position. Bxc6 is superior but Bb5 and Be2 seems winning also.
IIRC after a while I got +4 for Bxc6 and around +2 for alternatives so it looks like Bxc6 is best.

From about 100 positions in this thread, I removed easiest, incorrect and well known ones.
It's still 39 positions (still 9 positions from the ERET set)
Thanks a lot, Vincent!
Is it ready to be stored as suite or still under work?
Nr.5 (1.Bxh7+) as single best move has no discriminiation to second best 1.Bxb8.
Both are #12:

BTW e.g. 1.Bd6 needs only about 11 moves more to mate still, here after Backward and 1.Bd6:


Analysis by Cfish 041218 64 POP N:

1...Rbc8 2.Bxf8 Rxf8 3.Qb4 g6 4.Bb5 Bxb5 5.Qxb5 Rb8 6.Qb6 h6 7.Rc7 Rf8 8.Qxb7 Kg7 9.Qb4 Kg8 10.Qe7 d4 11.Qd6 Re8 12.Qxd4 Rf8 13.Qd6 Re8 14.Qd7 Rf8 15.Qe7 h5 16.Qf6 Kh7 17.Qxe6 Kg7 18.Qf6+ Kg8 19.e6 Kh7 20.Rxf7+ Rxf7 21.exf7 h4 22.f8Q h3 23.Q6f7#
+- (#22) Depth: 41/45 00:00:47 1308MN

So yes, It's an interesting position, but for single best move- suite it's not so good, it's not suitable.

This one, nr.7, is to be found in Noomen- and Hiarcs- book, at chessbase online 87 games are given with it.

I need some more testing with SF-matefinder and Houdini 1.5.
I'd like to get results for Komodo because I don't own it.
My main engine is Stockfish but sometimes a position is absurdly easy with another engine.

>Both are #12:
Thanks for the correction. I will remove this position.

I'll give the 40 a try with k12.2.2, if you want.
What hardware- time would you prefer?
How about 1'/position at 24 threads of 12x3GHz and 4G hash, Fritz14-GUI, 1extra-ply?
