I don't mind hype either, but they did make some errors in the video. Like
saying Hydra beat GM Topalov. When in fact it was Fritz that beat GM Topalov.
They also said no program attacks from the center like Hydra. What does this
mean? And the video said Hydra has a big advantage over other programs because
of it's strong opening moves? The video also said Hydra proved itself the
strongest chess engine in the world...by drawing GM Topalov??
Hydra maybe the best program in the world. I don't know. I do know where Hydra
claimed it proved itself the best program. Fritz had a better performance and on
much slower hardware then Hydra. And Fritz did beat GM Topalov where Hydra drew
the game with GM Topalov.
