Hard talkchess 2016 beta 1

Post by Vinvin » Mon Nov 09, 2015 3:52 pm

After recent tests, I saw Stockfish made big progress on the previous (hard-2015) set.
I removed the first (easiest) positions and add some new positions on the beginning.
I ran this beta 1 with Stockfish-151102 and Komodo 9.2
Conditions :
- 1 core
- CPU i7@4GHz
- 2GB hash
- 1 hour per positions
- 6 pcs Syzygy on SSD
- 2 instances of SF + 2 instances of K9.2 run simultaneously (2 backward and 2 forward)

Remarks : the results for K9.2 are very unequal (with 1 thread !) from one run to another one. See positions #24 to #127
In this post, you'll find results for SF then results for K9.2 then the 133 positions.

131 is a nice position but apparently SF and Komodo both find it very easy.

Here is a tougher one you might consider subsituting:

Position 125 to 133 are special. The idea is to find the right eval (see the fen string, 130 to 133 are winning).

The position you gave is quite easy for SF, a couple of seconds on 3 run :

Code: Select all

I have my doubts about this one. A deeper search gives a better score for an alternative move than my best search that found the proposed bm.

There are 4 positions where an engine has found the key move but another move scored better. I would be interested to see a chess engine output that shows the key move to be superior.

Here are the 4:

#1 and #4 are already planned to be take out.
About #2 (Smirin-HIARCS), I've not yet study it myself. Details here : https://en.wikipedia.org/wiki/Fortress_ ... ortress.29
About #3, it's very long, I saw the solution. Computer search is not (yet) enough deep. But I'll investigate.

Thanks for your help !
