It could as well be a non-conforming way by the controller to set up a game
with free handicap (or higher handicap than 9,...). I don't think we
should burden an engine with interpreting two consecutive genmove's.
(Should the engine add a PASS into it's private game tree? That would
clearly contradict the explicit wordings about move history in Gunnar's
GTP v2 draft.)

I think the point is one shouldn't stretch a protocol or one will run into
ambiguities at some point.
