Subject: Revert evaluation drift
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=e145c0d3e278fb601db49cc16076f10a30b60f19

Revert evaluation drift

Still not clear if it helps and, especially, how it
helps. So revert for now to avoid any influence on
future feature now under test.

With this patch we come back to be functional
equivalent to patch e33c94883 F_53.
