I guess that raises a follow-up question. What material is sufficient to
force checkmate.
Q + N vs N ?
K + N vs N ?
R + N vs N ?
two Rooks + N vs N
two Bishops (on opposite colours) + N vs N
The Queen mate is easy and in fact the Queen could force mate on it's own
without help from it's own Knight. I'm pretty sure the two rooks can do
it. I'm not sure about the one Rook though. The King may be able to but
I'd have to work it out. The two Bishops, probably, but again I'd have to
work it out. Had anyone actually played this game. Are strategies similar
to the conventional game, ie, control the centre, develop your pieces etc.
