Nothing seems to help here. No wonder, 'chessowl' is just infamous for spreading all kind of SF clones.
Indeed. I wonder what goes wrong with guys like him.

Re: Official Release of Ethereal 11.75, supporting MultiPV

It's probably better if you could set the perfect setup for Ethereal 11.75 under Linux/cutechess and then if it's running perfect, my "obviously bad setup" is causing the problem. Why should I? I'm not interested in testing Ethereal like you seem not interested in understanding what processor cores...

Re: Official Release of Ethereal 11.75, supporting MultiPV

Thank you very much for your suggestions not related to Ethereal. This is about Ethereal 11.75 and let's focus on the problem reported. I would appreciate if you could run Ethereal 11.75 on Linux with cutechess with concurrencies you desire and report if you have the same problem that I posted like...

Re: Pawn hash table, a little disappointment

Pawn hash (as well as position hash) are computed on the fly in apply or applyNull and computeHash will early return if already computed if (p.ph != 0ull) return p.ph; applyNull is xoring zobrist key for color and possible ep but this is bad design (this is because eval is returning score from stm ...

Re: Pawn hash table, a little disappointment

This line in your ::eval() seems strange: if (!getPawnEntry(*this, computePHash(p), pePtr)) { ... Seems that by calling computePHash(p) you recalculate the complete pawnhash from scratch? I checked that you already do "delta-hashing" in your movepiece so recalculating should not be necessary and may...

Re: Pawn hash table, a little disappointment

I'm using a total size for this table that is 1/16 of the TT. The table is well used, often there is a ratio of 10 read for only 1 write. But this is a slowdown of about 10% in knps ! I wonder how others engines behave ? There must be something wrong with your code. I would have a look but it seems...

Re: longest 6-man EGTB win

This simple 1-liner on my syzygy folder (with some 7-men files and only searching for exactly 100 ply wins) gives: G:\syzygy>findstr /C:"100 ply;" *.txt KBBBvKQ.txt:Longest win for black: 100 ply; 8/8/8/8/8/8/k1K1B3/1q1B3B w - - KBBBvKR.txt:Longest win for white: 100 ply; 8/8/8/5B2/8/2r5/8/BK1k1B2 w...

yes 1.3 of course :)

Minic is totally killed by Komodo 10, I don't even try 13 yet ...
Ah, okay. That makes sense. Didn't know there was a 1.3. Just found it even for download on their site.
