I have just installed jdk 14, so now I have 3 java versions installed. However, I have had two problems with java 11: 1. Some older java engines run only with java 8. 2. 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...

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...

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.

Thanks!

I have just released chess22k 1.13. This is mainly a bugfix/code-cleanup release which is about 20 elo stronger than the previous version.

Amersfoort is a good location for me but unfortunately I cannot participate that weekend.
Good luck all and see you next time!

Hi, Java 11 is installed, however it is impossible to run your engine. Pity. 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...
