I'm going to give up and claim its impossible to guarantee a win from that situation. Please message me and tell me otherwise.

Nice try. But I'm afraid I can't allow colour-switching or illegal moves.

1. h8 a1 2. Qe8

Then Black has no way to stop mate.

2...Qf6+ 3. Kd7 Qd8+ Qxd8#

Some other possibilities:

if 2...Qd4+ (or Qd1+ etc.)
then 3. Ke7+ Qd8+ 4. Qxd8#

if 2...Qh8 (or Qa4, Qe5, etc.)
then 3. Qxa8+ Ka8 4. Qe8 Kb8 5. Kd7#

Is this correct?

Edit: I thought my answer was correct, then I thought it was incorrect, now I think it might be correct again. So I'll just leave it.

That was a very cool one! Took me about half an hour to figure it out, which is quite alot, considering the few possible moves.

1. h8=Q a1=Q 2. Qg8! (that way Black can't playing Qg7 lateron) Qa2 3. Qe8 Qa4 4. Qe5+ Ka8 6. Qh8 and Black can't prevent mate, just extend it for a few moves by giving the queen.

edit: Your idea was correct, carpenoctem, except I think 2... Qg7 is the reason why White can't play Qe8 right away.

Yes, I went through it rather hastily, not considering 2...Qg7. Ironically, I thought of both 2. Qg8 and 2. Qf8 prior to Qe8 but then somehow confused myself into thinking those wouldn't work. That certainly appears to be the correct answer--good job.

by advancing to queen, black can only move kingy to corner, else advance pawn to queen and lose her immediately. I think an advanced player would retire wounded having fought on to miss by that one elusive step - so near yet so far. Some could/would play to the bitter end....

Don't forget stalemate, when Kingies have nowhere to go.
