There still some positions from King Solomon to add (maybe the first is too easy) :

r2rq1k1/pp3bpp/2p5/3p4/P1PPp1QP/BP2P1P1/5P2/2R2K1R b - -
r5k1/1ppq1bp1/2n4r/1BBn1p2/p1NPp2p/P3P1P1/1PQ2P1P/2R3RK b -
bm is Bh5 for both.

r1b2rk1/pp3ppp/1n2p3/3pP3/2P2B2/b1PB1qP1/P1Q1NP1P/1K1R3R w - -
1. Nd4 with at least +2 or equivalent winning score.

+13 positions to recheck from here : viewtopic.php?p=731553#p731553

After some checks :

Code: Select all

r2rq1k1/pp3bpp/2p5/3p4/P1PPp1QP/BP2P1P1/5P2/2R2K1R b - -
r5k1/1ppq1bp1/2n4r/1BBn1p2/p1NPp2p/P3P1P1/1PQ2P1P/2R3RK b -
bm is Bh5 for both.
For both positions, Bh5 is found often by luck because the eval is 0.00 as some other moves.

This one is very good : r1b2rk1/pp3ppp/1n2p3/3pP3/2P2B2/b1PB1qP1/P1Q1NP1P/1K1R3R w - - bm Nd4

I have started a big clean up of this 223 positions.
I removed positions for some reasons and some other positions still pending (for some days) :

7 not good test positions, because second move is close to the key move : numbers 47, 58, 63, 132, 135, 141 and 158 in the initial list

Code: Select all

2r3k1/1r3p2/1qb1pPpR/3pP1N1/p1pP4/PpP5/1Pn1BB1P/3R3K w - - bm Rg1;

r1b1r2k/pp1n1pp1/1qpb3p/8/3PB2B/5N2/PPQ2PPP/R3R1K1 w - - bm Bg6; c1 "diff=9";

3 key moves that can be found by pure luck : numbers 95, 131 and 149 in the initial list

q7/b1p5/kp1p4/p2PN3/PPP5/1K6/8/5B2 w - - bm c5+; c1 "diff=7";

16 key moves too easy to find : numbers 61, 62, 80, 81, 84, 90, 93, 102, 136, 157, 192, 195, 198, 203, 208 and 217 in the initial list
(I hold some other easy positions because in the past, some engines has trouble with them)

2 positions that produce some chaotic (buggy ?) behavior in Stockfish_19082608, best move is lost or other moves still the best for a long time (numbers 160 and 167 in the initial list) :

Code: Select all

r1b4r/p4pk1/P3p1p1/1pBpPnPp/2pP1K2/2P3P1/4BP2/R6R w - - bm g4;
8 positions I still consider unclear, I have to spend some hours to debug them : numbers 36, 78, 83, 113, 139, 146, 179, 214 in the initial list

I ask help to forumers with big machine: please run this 8 positions, 3 best moves, around 200 billions nodes search (around 3 hours at 20 millions nodes/sec) and post the log here.

Code: Select all

The remaining 187 positions still very good.
I hope to post the final version of the "hard-talkchess-2020" set next week :lol:

The questions for these positions are :

How to win this position with white ?
2k5/2p5/1q1p4/pPpPp1pp/N1P1Pp2/P4PbP/KQ4P1/8 w - - am Nxb6+?; c1 "diff=10";

Is this position really interesting ? g4 seems to be easy to find "by luck".

Is Qg4 the only winning move ? How strong compare to other moves ?

I ask help to forumers with big machine: please run this 8 positions, 3 best moves, around 200 billions nodes search (around 3 hours at 20 millions nodes/sec) and post the log here.
