Subject: Force iteration to start at 1 in analyze mode
X-Git-Url: http://winboard.nl/cgi-bin?p=bonanza.git;a=commitdiff_plain;h=4106e127a492aa4c0f5f01112b824fcb678b2d52

Force iteration to start at 1 in analyze mode

Starting at a high depth based on a previous PV is undesirable here,
especially when that PV might start with a move that is now excluded.
