Thanks for testing!

Now I am working on a new version of Zevra 2.0. This is a completely new program, it does not use any more object-oriented programming. At the moment, only a move generator is implemented, which is 2 times faster than in Zevra 1.x :)

Intel Core i7-860:
Perft 6: 119060324; speed: 17735knps
Zevra 2 is my chess engine. Binary, source and description here: https://github.com/sovaz1997/Zevra2
Zevra v2.5 is last version of Zevra: https://github.com/sovaz1997/Zevra2/releases
