[D]1Q6/K7/8/3k4/8/8/8/8 w - -

I had this position in a game and I wondered what the shortest route to mate
is.  I have seen methods by which one advances the king first and other methods
where one advances the queen first.

I think that Qf4 might be the best move although I can't prove it.

I gave the problem to Fritz6 thinking that it would either know the answer
immediately or would be able to find it quickly.  After some searching it came
up with mate in 31, but after playing a move or two it quickly turned into mate
in 9.

After searching several hours Fritz came up with Qb4 mate in 26.  I don't know
if that is the fastest solution since I have heard that one can mate with this
in less than 20 moves.
