Subject: Don't need to check for bestValue < beta to split
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=52bbf372bb4956595e730f4dba05ee6b78305ad0

Don't need to check for bestValue < beta to split

With rearrangement of fail high code this condition
is no more necessary.

Found by Jörg Oster.

No fuctional change.
