Tough Tactical Test, the 35 hardest positions

Post by Vinvin »

I ran this set (found here : http://rybkaforum.net/cgi-bin/rybkaforu ... ?tid=33508 ) with 5 engines : Bluefish-XI, Corchess_V6, Stockfish_20062710, Houdidit Tac=1 and Black-Diamond-XI. 60 seconds (6 cores) per positions.
I hold the positions found with less than 3 engines. It still 35 positions on 100.
This was before NNUE, 1.5 months ago.

It's positional tests that are more important for an already super strong engine. They are already born to calculate...not to 'intuit'. That's the hard part.

Those are also much harder to create.
And tactical tests are more fun because of the surprise.
A quiet, positional test must have many close alternatives or it is a tactical position.
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.

Second best of three trials, worst was 58", best 23" to stay stable on 1...a3.

Hardware still the same as in all postings of mine in this one thread: 12x3Ghz Xeon X5670 CPU (SSE4.1-popcnt compile) 32 G hash.

Best move is found without Fortress Detection code like in Black Diamond coming from Crystal by Joseph Ellis, just to mention why in your tests Black Diamond might have scored well too in this position.

So one can see here well, what a good tactical net can do to guide the search into right direction, even if search is the same of the same engine and could be better by itself of course too, as for this one position by FD- code e.g.

Therefore I don't like embedded nets at all, they'll let development of nets ignored behind Elo- only- testing in framework maybe, as well as Hybrid- Eval did already. Elo in framework may be fully blind for developments not tested as much as mainstream is.

That's a point for Thorsten Czub btw., regarding the other thread of his about human and engine- playing, programming and selflearning.
At least testing should be somewhat more human- guided and less automated and selfplay- guided, not to speak about guidance of net- training, which nowadays might have most potential, if it isn't restricted to reinforcement and selflearning only, but starts having steps into .pgn- learning also
:!:
Even if of course there's much room for human intervention in coding too, especially with better and better eval, hard- coded and or net-supported, helping to refine the search also.

Just my two cents regards
Peter.
