Hi,

I don´t think so for book-entries. It could be an idea if you have a position
learing feature. Suppose your engine stores bad positions that where lost, but
your engine things that it´s good. If then you store such position automatically
in a "learn-file" then perhaps it makes sense to put those position in the
transposition table.

Greetings Volker
