Cheese 2.2 is available :
http://cheesechess.free.fr/en/download.html

Code: Select all

	- fix invalid moves in pondering
	- fix FRC makemove problem introduced in version 2.1
	- fix UCI strength problem with UCI protocol
	- randomness is now only used in personality
	- don't count pruned nodes
	- change king PST

Code: Select all

Rank Name           Elo    +    - games score oppo. draws 
   1 Cheese-22-64    12    4    4 10000   54%   -12   47% 
   2 Cheese-21-64   -12    4    4 10000   46%    12   47% 
I changed parameters for engine strength reduction, but I was not able to tune it as I want.
It's reducing the speed by default but there is an option in cheese.ini to reduce searched nodes.

I will probably not release a new version before modernizing my code (C++11, and more).

Hi Patrice,

Do you plan to provide arm7 binaries like for previous versions?


Thanks,

Al.

Yes, on the download page you have Android versions for armv7 and armv8, and Raspberry pi versions.

When I try to go to the webpage BitDefender throws up this error:

I think this is because it's not https, but there is no problem the website is plain html (no javascript, or forms).

Or maybe a false positive on engine binaries, I have no problems with Avast.

Thanks. I chose to ignore what Bitdefender was saying and downloaded it anyway. Then I scanned the *.exe and it didn't find anything.
I should have known, Bitdefender is always throwing up red flags or putting chess engine *.exes into quarantine as soon as I try to use them.
