Hi uri:
by ordinary ones i meant ordinary EGTB (the ken thompson ones)as opposed to the
newer nalimov EGTB.i wasn't referring to a particular chess engine having the
capacity to access them in the search.it is my understanding thqt with nalimov
EGTB the chess engine can actually search for a position encoded within the EGTB
as opposed to the older EGTB which kick in only when a psoition has actually
been reached which is within the EGTB.

correct me if i'm wrong
