When RepeatPV is false PolyGlot does not repeat the last pv string.
Due to the way kibitzing is implemented, KibitzMove is disabled in that case.
+=item B<WbWorkArounds> (default: false)
+
+The intention of this option is to provide work arounds for
+xboard/winboard bugs should they arise. Currently it only prevents
+"feature option=" commands which contain "Draw" in their name from
+being sent to the GUI. Some versions of xboard/winboard contain a bug
+which causes such options to be interpreted as draw claims by the
+engine.
+
+Engines that send options with "Draw" in their name are Rybka and HIARCS.
