I set up a position with Zappa and it analyzed and then made a move. But during its analysis it never in any of the 3 lines showed TB= But then i went back and looked at the log file and it showed the correct path, how many bytes were allocated,said that it had found the TB,s, and even showed the compression memory. I am confused. It looks according to this that Zappa accessed and used the tablebases, but why didnt it show TB= in any of its analysis lines when i was running the position. Or did it find them? I am lost.
