Is it always possible to force a mate with a Queen vs. a Rook (ie one
player has a Queen, the other a Rook, and those are the only pieces on
the board apart from the Kings).  If so, what is the strategy?

As an example, start with an initial setup of:

  White: King at d7, Rook at d6
  Black: King at e5, Queen at g1

White's turn to play.  Which incidently is from a Korchnoi/Kasparov
game played in the late 80's (Kasparov played black).  Korchnoi played
about 5-6 moves after this position before he resigned.  I myself
cannot see a sureshot way for Black to force a mate, but I'm basically
a beginner.

Please email me directly, or at least cross-post to gnu.chess, because
I do not get alt.chess newsgroup.

Thanks in advance.
