The engine is useless.

A very (very) interesting chess project !

How do you guys find this stuff so quickly?

Here's the story:

I'm sure some of you have heard of "OpenClaw" (formerly known as moltbot and clawdbot) - its an open source bot which can take any LLM, use it as a brain and work basically 24/7. It is even proactive and will work without guidance.

I created one, named it "Jay" and got him working on my "dream" engine.

Problem is, he is running on a Mac and has no windows environment for debugging.

Maybe one of our geniuses in the community can figure out what is causing it not to run, but as you guys know, I can't code if i life depends on it.

I do plan to give "Jay" some way of running on Windows though. We'll see.

The project is mostly curiosity (if he could pull it off), but also. personal passion.

Nobody was supposed to use it yet, but Jay thought the easiest way to give me binaries to test was to just create releases.

Impressed by how fast our community found it. Still a LOT of passion for computer chess here.

Funny, My youngest son just setup one (OpenClaw) on his PC and called it "Mother". Mother do this, and mother do that ... Drives my wife crazy! He says it with a European accent of course.

PS:
Does anyone have any ideas for solving sleep problems before I flood the whole forum with news? No, no... I'm just kidding.

Unfortunately, version 6 is bugged. It seems that I am cursed with each release

[Aleks Peshkov]

Petrel 3.3 (NNUE) and Petrel 2.3 (PeSTO) released.

Minor update. I expect 30-50 Elo gain from 3.2 and 2.2.

Hi Philippe,

hope you can find the problems.
The French programs are the first, after Stockfish I will test with my ETOC-G idea.

Reason is very simple:
French programmers helping me in Winboard and Arena times most with Website activities, ideas and give me 100% support, also great support for Martin Blume. French programmers powered Winboard a lot, without all they work they do ... long years ago, but never I forget it.

The trophy for the tournament in Massy (French programmers computer chess tournament) comes from me in combination with a deal with the German chess magazine CSS ... as thank you.

So, each French programmer are allways in first position (in my brain).
And Zangdar is very strong and must be test very soon.

Best
Frank

So I have a hell of a lot of respect for it.
Franck ZIBI, Lucas or Christian BARRETAU, all the others ... so nice guys. Franck ZIBI was the French answer to Rudolf Huber. Rudolf Huber is a German programmer (SOS). At this time all German programmers I know had the same opinion. The programmer with the most knowledge about programming in Germany. For an example: Opinion from World Champion Stefan Meyer-Kahlen at this time, but not only Stefan say that. Franck ZIBI was the French answere.

Now you must take over the inheritance Philippe.



It also fits somehow... a country to fall in love with.
