Subject: Remove an useless condition in equal SEE pruning
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=204efb109bf125e1fdbc8dbb011c13a8e5aa9e8c;p=fairystockfish.git

Remove an useless condition in equal SEE pruning

Because we are never in check there and evaluation cannot
return a mated value the condition is useless.

No functional change.
