Subject: Fix bestmove output in multi PV case
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=6ed409eceeb8caa81604c107b5ce0713b88bbae2

Fix bestmove output in multi PV case

When MultiPV > 1, always take bestmove from the RootMoveList
(and don't bother with a ponder move). Without that the bestmove
is most probably incorrect.

Patch from Peter Petrov.
