In Paderborn I used the same machine. In round-1 the game Rebel-Arthur Rebel showed illegal lines in its main-variations also several unsound pawn sacrifices. After the game the machine was carefully investigated by the KryoTech man who was present in Paderborn but no errors were found. I concluded it was software because some 4-5 months ago I had rewritten the code of main variation (retrieving the info from the hash table) and it was logical to assume (at the time) there maybe was a little bug inside. I should have been more attentive. Ed > >>James >>> >>>Pierre
