Subject: Sync Root new depth to what we do in search()
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=932ae761c6e3fd3e9b202283379e487a5c187989;p=fairystockfish.git

Sync Root new depth to what we do in search()

This allow us to restore the old depth 12 benchmark
and fixes one and for all the depth mess.

Test confirms no regression:
After 5658 games 892 - 924 - 3842  ELO -1 (+- 5.2)
