Subject: Fix a warning under MSVC
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=e3b03278129e4d7f130826aef209668b3268aa94;ds=sidebyside

Fix a warning under MSVC

Compiler complies that 'cnt' is initialized but
unused (in !CheckThreeFold case). Moving the
definition of 'cnt'out of the loop  seems to do
the trick.

No functional change.
