Subject: Remove useless razoring condition
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=eccccba0ce4e2d627cbe2adb1bf4a692d595ca99

Remove useless razoring condition

Condition is always true! For any value of the
array index! Even an out of bound array, like
razor_margin[120]!!!!

No functional change.
