New engine releases & news 2021

[mvanthoor]

Well... I saw someone post something about "The lost art of chess engine programming" in Stackoverflow some time ago. If one art _isn't lost, it's chess engine programming (on the PC). Since I've been busy with this, I've seen 10-15 engines pop up. And then I may have missed a few.

How do you know the version number is 4? At the site there is only version 3 and the engine does not display any version number.

Actually it should be Shallow2 v4 to be precise...

4.7z
I've named it as "version 4"

Ah, thanks. It is probably too difficult to display the version together with the name.

New Engine - Panzer

Github Repo Here https://github.com/msarchet/panzer

Bitboard based C++ engine, currently compiles on linux, working on completing bits for Windows builds. Just got it to actually playing chess with a basic AlphaBetaMin/Max evaluation. Currently using the PieceSquare Evaluations from the CPW-Engine. I have quite a few todos left. But I'm pretty excited that I got it working. Up next is finishing my FEN string interpretation and adding Quiescence and Transposition Tables. On my Ryzen 9 5950x my multi-threaded perft evaluation gets around 150M-250M NPS depending on the number of nodes searched. I don't remember the single core numbers off the top of my head.

I previously wrote two move generators one in Python and another in C++ (inside of Panzer's src as old version), both using the 0x88 representations, they were error prone and slow in various cases which made debugging beyond perft(5) painfully slow.

Thanks for the info. If I am not mistaken it currently doesn't support any engine protocol?
A search through your repo sources revealed zero hits for uci/xboard.

For being called a (usable) 'release' it should support one of the above mentioned protocols for automatic testing.

New engine: Pawn https://github.com/ruicoelhopedro/pawn.

"A UCI alpha-beta chess engine, largely inspired by Stockfish." It's far simpler than SF, I wouldn't call it a derivative; anyway source code is there.
I made a Windows binary, available here: https://e4e6.com/download/. 1'+1" Elo ~ 2330.

The Pawn version on https://e4e6.com/download was reported as a virus.

But it isn't, I compiled the exe myself. VirusTotal sandbox says it's clean https://www.virustotal.com/gui/file/8be ... /detection.

Thanks, didn't realize this until after I posted in the forum. I believe I found the canonical source for uci here http://wbec-ridderkerk.nl/html/UCIProtocol.html?

Yes, it's the classical text.

Hi Alex,

Could you compile one for very old hw like mine (AMD Phenom II x6)?

Thanks in advance,
Carlos
