Subject: Enhanced Transposition Cutoff

Has anyone tried this?

I found the following description at:
http://www.xs4all.nl/~verhelst/chess/search.html#enhanced-transposition
----------------------------------------------------------------
There may be several successors causing a cutoff and we want to use the
one with the smalles search tree. One idea that has been tried is to
look at all successor positions and see if they are in the transposition
table and cause a cutoff. If one such position is found, no further
serach has to be done.
This can save about 20-25% in total tree size.
