The score I had was in favour for Anmon though Strangely enough also Which actualy is strange Aristarch had trouble in finding some pins too in some cases if it could choose to pin a piece or not it choose for the latter Which made positions which it should win to a draw The program also did not have all options in the Shredder5 interface as mentioned in the readme file. In the Arena Interface options did not even become active But this are still only quick conclusions. Perhaps i find some more conclusions later. Regards Marc van Hal
