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.
And that is the point.

'Positional' tests may sometimes have no single 'correct' answer. It is about moving the game along towards desirable structures/opportunities. Tactical tests - particularly those where the speed at which an engine finds 'the single best answer' are pretty lame in this day and age.

Positional tests would often have multiples solutions and one might have to grade say 2 or 3 possible moves/'ideas' on a sliding scale...perhaps even giving 2 answers the same value...or very close.

It seems to me that engines often outplay one another by getting those better (lets call them 'positional') positions more often when their natural tactical abilities can cap off their good play. That is the way humans normally do it: good positions lead to tactical opportunities. It is why NN's are actually interesting as chess playing engines and why I would love to see more 'positional tests' devised and think we should value them more these days.

That is why I have historically valued engines like Komodo over others.

here is #46

You mean 16 instead of 46.

Three trials with Cfish Use NNUE Pure and Dietrich Kappe's DarkHorse 0.2- net, here's the best one, second best was 22", worst 26".

Would have let it run longer to wait for same eval as with the other net, but time for editing was getting short.

Would have let it run longer to wait for same eval as with the other net, but time for editing was getting short.
Selfquoting regards
Peter,
My reference is the # referenced in the fen:
1r1qr1k1/3bb1p1/3p1pPB/2p1pP2/2PnP3/p1Q2N1P/P2RB2K/6R1 w - - bm Nxd4; id "TTT1.046";
and whether it was solved or not , was the count of "zero" in the initial post - I did not check any other posts to see if was solved subsequently.
My apologies if I created additional confusion.

Confusion reigns regards,
Mike B

Nevermind, Michael!
I downloaded the 35 fen- strings from the first posting of the thread of Vincent's and within those it's nr.16, confusion may come from the whole set on the one and the 35 hardest ones collected out of those from the posting on the other hand.

So put the blame on me for that, anyhow we are talking about the same positions and I just had wanted to point out, that Dietrich Kappe's fine tactical nets DarkHorse and NighNurse help solving problems, especially with NNUE Pure combined, sometimes more than refined search of SF itself does.

Nevertheless internal MultiPV (Tactical) and the Presearch Pro Analysis are great features of their own, I wouldn't want to miss those for analysis anymore.
Thanks again for the compiles. You probably already read my silly questions about embedded nets and by UCI- path changed other nets and RAM, didn't you?

Search and nets and confusion reigning regards

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.
And that is the point.

'Positional' tests may sometimes have no single 'correct' answer. It is about moving the game along towards desirable structures/opportunities. Tactical tests - particularly those where the speed at which an engine finds 'the single best answer' are pretty lame in this day and age.

Positional tests would often have multiples solutions and one might have to grade say 2 or 3 possible moves/'ideas' on a sliding scale...perhaps even giving 2 answers the same value...or very close.

It seems to me that engines often outplay one another by getting those better (lets call them 'positional') positions more often when their natural tactical abilities can cap off their good play. That is the way humans normally do it: good positions lead to tactical opportunities. It is why NN's are actually interesting as chess playing engines and why I would love to see more 'positional tests' devised and think we should value them more these days.

That is why I have historically valued engines like Komodo over others.
Thought I asked....see I forgot. What is generally considered the 'best' Positional test suite' out there?

I had a lot of help from CCC, who helped me debug it. There were 3 or 4 attrocities in there for the 1st version, and a few other iffy ones.

But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

#4 and #14 took more than 60 seconds for Bluefish. I use the special settings.
