1. Nunn test 
Deep Shredder 12 - Hiarcs 13.1 MP  8.5 - 7.5 (+5 =7 -4)
Hiarcs is clearly better in tactics while Shredder wins positional battles.
The whole match was almost equal. Hiarcs was even 2 points ahead but finally lost tightly.

2. Without book
Deep Shredder 12 - Hiarcs 13.1 MP  8.5 - 13.5 (+5 =7 -10)
Hiarcs is for long years known to play excellently positions from his games.
Shredder seems to have a good book build-in but it doesn't  help.

3. Without book
Rybka 3 32bit - Hiarcse 13.1  MP   7.5 - 12.5   (+5=5-10)
Very nice surprise for Hiarcs fans.  Hiarcs is able to beat even Rybka in his positions.

4. Nunn test 
Rybka 3 32bit -  Hiarcse 13.1  MP    11.0 - 9.0    (+5=12 -3)
A honest result with nice games.

Resume
After some delays a doubts based on Thurlingen  Hiarcs is again a very strong engine with interesting playing style.
