Subject: Fix a warning with MSVC in 'analyze' mode
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=c6fc51c5ea769098a11d14680e611ac88eec94ad

Fix a warning with MSVC in 'analyze' mode

Here MSVC is worried that

StepAttacksBB[PAWN][psq]

could overflow, so change psq initialization
to clarify psq is always less than 64.

No functional change.
