With the newest code of Eugene Nalimov, for "symmetrical" TBs, only one of nbw and nbb is needed. kbbkbb.nbw and kbbkbb.nbb would be exactly identical anway (at least I think this). This is also true, for the 4-men tables. Programs, that use the newest source of Eugene only need one of KQKQ, KRKR, KBKB and KNKN. If I understand correctly, however still .nbw and .nbb of KPKP are needed (pawn positions have less symmetry ...) AFAIK all table base access code of Eugene, that is prepared for 6-men TBs can take advantage of the above mentioned symmetry. So, there is no need to have the .nbb files at all. Older versions of Eugene's code (that also was not able to access 6-men TBs) needed both files. Regards, Dieter
