It might only be accessing 5-piece tablebases in a search line which results in the capture of one of the pieces. As far as I know, Shredder 7 accesses the single part 6-piece tablebases, ie the tablebases that don't have a digit in the filename. The only programs that I know that access the multi-part 6-piece tablebases are Hiarcs 9 and Crafty. I assume that Shredder 8 can be added to this list. Ask me again next week.
