Subject: Small code cleanup in LMR
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=b1bb376c3cc9a2e197759b3e6f0d365c8aae7e72

Small code cleanup in LMR

In a recent patch we added comparing capture history to a number for LMR of captures.
Calling it via thisThread-> is not needed since capture history was already declared by this time -
so removing makes code slightly shorter and easier to follow.

closes https://github.com/official-stockfish/Stockfish/pull/3297

No functional change.
