It wouldn't be surprising if the best tournament engine was also the best
analysis engine. I'd expect a very strong correlation :)

That's a tough question, I don't have a very good recipe for that. I think the
endgame is easier to analyze.

Sorry there is no webpage. I don't think it would be very interesting because I
use mostly older versions of other engines.

If I update the opponents to newer versions then I can no longer compare the
results with old versions of frenzee.
