Hiarc's plays at or near the the top in Blitz 5 min. Its superiority in >play against other programs on chess server drops as the time element is >increased.

I do not think that hiarcs positional understanding is superior relative to faster searchers. I saw often positions that Hiarcs7.32 does not understand and Junior does understand. This is the reason that Hiarcs has problems against Junior. I believe that better positional understanding should be important at long time controls because often there are quiet positions when there is no complicated tactics and if you find the right moves in these position the tactics later is only for you.
