Jim I really don't know, I don't have enough data to formulate a conclusion.

What concerns me is you have made statements that may indeed hurt the sales
of HIARCS 8 thus the programmer Mark Uniacke, however unintentional.

Keep testing, but try long T/C's and very fast ones as well. Game 60' seems to
not do H8 any justice? Still I can't be certain it wouldn't do better over time?

It's still just too early to form any conclusions about H8 at this time.

Regardless, it is still a very strong engine, _apparently_ stronger than it's
predecessor H7.32, according to early tests on this board.

I do suspect that H8 would benefit from very long T/C's on very fast hardware.

However it would be nice if Mark Uniacke, would comment at this forum. It might
clarify some issues on H8?
