Breaking News (29.03.2025): Another CS organized..thanks and congrats to all, as players up to 40 MB! And as LVII CS it seems all stable again, no crash / no game lost on time! Actually as same words are going for almost all recent organized tourneys.. You know 'stability' is so important..In other words, it's a heart of success! Otherwise, our produced tour results may lead to wrong conclusions, such As unfair rankings..Moreover, re-starting tours etc. for any TD is a BIG pain.. Sure I admit that especially for my side 'strength' (in improvements) plays Important role to keep Me alive in testings..And I assume for many as well.. Yes..one of beast engines in this hard arena is Obsidian, just unstoppable! Managed to be Number One not only now plus in other serious tours too! And that means a lot! PlentyChess + Berserk are 2nd..both proves again To all of us that these engines are one of greatest! Where SF-Mini is 3rd.. As new entry: impressive! Plus so good points come by many others too! Meanwhile for more information about latest new competition OpenChess
