Bob forgot to mention the mirroring needed for positions with pawns. The pawn
TBs are not identical (they have the identical contents, of course, ordered a
bit differently).

C:\tb>dir kpkp*

05.08.2003  12:00         1.111.988 kpkp.nbb.emd
05.08.2003  12:00         1.116.299 kpkp.nbw.emd

I think, current Nalimov code needs both (which may be not intended). From the
code:

	TB (kpkp, false, false, false, (T22<P, P>::IndCalcW), (T22<P, P>::IndCalcB),
3863492, 3863492)

The "fsym" is set to false.

Regards,
Dieter
