I believe it was in _the_ paper about transposition tables (I don't remember the
name at the moment). I recall that there was one chapter of this paper devoted
to transposition table replacement schemes and it showed that node based
replacement was better than depth based. The improvement was not trivial, but
not dramatic either.

I always find it interesting to learn how people probe, replace, manage
different tables, and so on. Thanks for sharing.
