Hard talkchess 2018 set - work in progress

Post by Vinvin »

Hi all,
I'm happy to announce the progress in the construction of my latest test set.
See here for some history : http://talkchess.com/forum/viewtopic.php?t=64914

I removed the least interesting positions from my 2016 set : http://talkchess.com/forum/viewtopic.php?t=67059 . It stills 107 positions that will be use as a base for the 2018 set. I'm publishing them in the next message.

After that I'll publish a message in this thread with the new candidates : 117 positions gathered mainly from the Talkchess forum. Some positions will probably be take out after some deep testing. Your feedback is welcome !

As always, thanks for your excellent efforts on EPD test suites.

For your combined two sets, there are the following positions where I do not have an analysis with the key move that has a better score than some other move:

Code: Select all

Naturally, I am analyzing all at greater depths now.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.

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.

But for this one, I put in "am Rc6" instead of "bm Kc1" :

Code: Select all

2bk2r1/5q2/1p2pP1Q/pP1pP1P1/P2P4/8/2RK4/8 w - - bm Kc1; c0 "AlphaZero-Stockfish game 9 2017 (analysis), posted in Rybka forum";
2bk2r1/5q2/1p2pP1Q/pP1pP1P1/P2P4/8/2RK4/8 w - - 0 1

Analysis by Stockfish 270318 64 BMI2:

1. +- (4.74): 1.Kc1 Bd7 2.Kb1 Qe8 3.Qh3 Qf8 4.Ka2 Rxg5 5.Qh4 Qb4 6.Qxg5 Qxa4+ 7.Kb1 Qxb5+ 8.Kc1 Qf1+ 9.Kd2 Bb5 10.Qg8+ Be8 11.Qg3
2. +/= (0.62): 1.Kd1 Bd7 2.Kc1 Qg6 3.Qxg6 Rxg6 4.f7 Ke7 5.Rc7 Rxg5 6.Rxd7+ Kf8 7.Kd2 Rg4 8.Kd3 Rg3+ 9.Ke2 Rh3 10.Kd2 Rf3 11.Rc7
3. = (0.00): 1.Rc6 Bd7 2.Rxb6 Kc7 3.Rd6 Kb8 4.Ke3 Be8 5.b6 Kb7 6.Kf4 Bxa4 7.g6 Rxg6 8.Qh3 Rg1 9.Qxe6 Rf1+ 10.Kg5 Rg1+ 11.Kf4
(Depth 52 finished, 3core @3.7Ghz)

So 1.Kc1 with a score >4 is for me the right move.
