Hi again,

To be honest, I didn't expect less from Hiarcs. A program that manages to stay
at the top ten with such ridiculous depths (I'm talking about V. 9) must have an
amazing evaluation/extension scheme (I've always had a blind spot for Hiarcs, I
have to say). I haven't tested Rybka, but I know that programs like Fruit are
just extremely stable in their eval, and their search provide them with even
extra stability, so they can be deadly at almost any time controls, but programs
like Hiarcs use a more aesthetically elegant approach that I find more
appealing; probably even more now with the version 10.
Again, we have this thing about different programs' approach working differently
against different opponents, so maybe Hiarcs' approach is just the super
anti-Glaurung one, who knows?. In any case, I am sure that Hiarcs 10 games will
be worth the waiting.
In the meantime, and for as long as your engine is 400 ELO above mine, I still
acknowledge with admiration the job you've done with your engine to remain among
such bests.
Best regards,

 Jaime
