Subject: Move sending of PV line to id_loop()
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=c006435bb4b93aa15ea904da50070f360e365291;ds=sidebyside

Move sending of PV line to id_loop()

No functional change apart form move reordering because
pv_info_to_uci() performs a do / undo_move sequence.
