SEIF 9 (Cont.)
The Magen Avraham writes there is a Nafka Minah for the various reasons given for covering the bread before Kiddush. The Nafka Minah comes in determining when to uncover the bread. That the bread should not be "embarrassed" because the Bracha on the wine is made first, it would seem permissible to uncover the bread following the Bracha made over the wine, though Kiddush was not yet finished. But as for the reason that the bread comes for the honor of Shabbos, it should only be uncovered (as to present it) after Kiddush is finished.
