As many of you will know, the interface code of Eugene does support (at least) two naming conventions. For kpk white to move, the external filename may be kpk.nbw.emd or kpknbw.emd. Eariler I had most files with the former naming (which gave some trouble for real DOS based programs). After a HD-crash, I had to download TBs again. The ftp server of Robert Hyatt was nonfunctional, so I downloaded from www.chesslib.no (which linked to some ftp). They used the convention with the single dot. Because I have all the TBs installed, I expect my program to say "egtb probes m, found n" where m is equal n. Just now, it appeared, that n was slightly smaller n. I investigated this, and it turned out, that probes failed for some knnpk positions. The TBs were there, however, and I also checked them with "datacomp t". I renamed ren knnpknbb.emd knnpk.nbb.emd ren knnpknbw.emd knnpk.nbw.emd and all positions were found again. Strange, especially, when we consider that most TBs work with the middle dot missing. I did not investigate the source code to find the reason. Perhaps Eugene will know it, and he might be able to easily fix it. IIRC the Nalimov code I am using is based on Crafty 19.12 (with one other bug I had reproted earlier removed). Regards, Dieter
