Java 8 is regularly updated (automatically), while java 11 is not. Besides, I don't know how to use them in parallel. If the path...

Re: chess22k 1.14 released

Long-awaited update. I have already java 8 and java 11 installed. Shall I install java 14 too? Is there a difference in strength when using different java versions? If possible, I would only install the latest version which is 14 and uninstall all older versions. If you don't feel like installing a...

chess22k 1.14 released

Mainly a bugfix version and improved SMP scaling.
Unfortunately no big elo gains, probably 20-30.
Build using Java 14 but also a Java 11 binary has been supplied.

Can't recall having this issue with previous versions though.
I just checked version 1.12 which has the same 'issue'. I will update this for the next version but don't know when it will be released.

There is not a simpler way to turn it ? :( Running my engine with OpenJDK is not that difficult: download the OpenJDK, unzip the zip file, go to the bin folder and execute the following command: java -jar [location of ches...
