I looked at the games and I saw that Hiarcs7 lost positions that it should not lose. It is possible that Fritz5.32 was lucky to play in the right side in a position that both programs do not know what to do with black and the only way to check it is to see if Fritz5.32 can beat itself in this endgame. You may be right that Rd8 was not the losing move but I think that after it black has nothing better than going back to c8. Re6 Nb4 Rc8 is Junior5.4's line after Rd8 Nc2 and not Rg3. Uri
