I don't believe Fritz or Junior or Nimzo 99 are doing anything or making any assumptions about positions. I believe the only searching done is on the CD ROM which is full of errors. The reason some of my positions are working correctly and yours is not I believe is because you are using the Fritz 16 bit and the SP1 only fixed the Fritz 5.32 problems. But it did not fix all problems and some of the problems you mention are still bad with the Fritz 5.32 GUI. You should understand that since Junior and Nimzo make the same errors when using the Fritz CD ROM it means that the problem is not with Fritz program but with the CD ROM. I you think the Fritz program is making "assumptions" then you must also think that Junior and Nimzo are making the same "assumptions". I don't think so. Jim Walker
