zurichess jura - preview release

[brtzsnr]

Hi, all!

In a month or so I will release a new stable version of my chess engine. Since there have been some significant changes and the project has gotten some publicity (e.g. it's used in picochess board) I would like to make a bug free stable release. Last time two small bugs were reported that I didn't catch in my tests.

Enough with the talk here are the binaries.
linux http://www.zurichess.xyz/zurichess-master-linux-amd64
windows http://www.zurichess.xyz/zurichess-mast ... -amd64.exe

Please DO NOT use these binaries for public rating lists. If possible just include them in your private tournaments or human-engine matches.

Thank you for the engine

Is it possible, that the "skill level" setting has no effect on the playing strength of the engine?

[brtzsnr]

Skills should work as expected, but I will double check, Do you have an example input on which you think it fails? Or is this through a GUI, e.g. Arena?

[styx]

I tested the Linux version in Xboard and ran it against a ~2000 Elo Engine. I don't know what the hardest skill level is (since the default value was surprisingly a "0") so I tested "10" and "0" which seems to be upper- and lower limit.

In both cases, zurichess destroyed the other engine (Bikjump).

Thank you for the feedback, it's valuable especially when it's repeated.

First I need to change the skill levels to match Stockfish scale (20 - best, 0 - worst) because this is what people are used to.

Skill level 10 ~= 700 Elo drop (for Graubuenden at least). I will increase the maximum Elo drop and retune the skill levels.

So indeed there was a bug in the skills level. I updated the binaries and made skills from 0 (strongest) to 20 (weaker by ~1200 Elo). Can you try again?

Thanks for reporting!

I can beat it, so I guess it works Thank you!

When can we await the stable Version for testing?

Hi, Werner!

Thank you for including Zurichess in your tests.

Today or tomorrow I will release the stable version of the chess engine. I waited for the new version of the Go compiler [1] which produces better code, especially on ARM platforms.
