How quickly can you find the shortest mate in this position?

Q7/5p2/5P1p/5PPN/6Pk/4N1Rp/7P/6K1 w - - 0 1

At first I got only mate in 4 but I guessed that it was a too long mate. I continued trying. It took me 20 minutes.

1.Qh1! hxg5
2.Qg2 hxg2


1.Qh1! Kxg5
2.Ng2 hxg2

Qh8 hxg5 2. Nf4#

If ... Kg5 2. Qg8#

(Sorry: meant If ... Kxg5) Took five minutes.

Oops. Sorry again. This works:

  1. Qh8 hxg5
  2. Ng7#


1… Kxg5

  1. Qg7 Kh4
  2. Qg4#

Formatting goes all strange here. The variant should be:

If 1... Kxg5 2. Qg7 Kh4 3. Qg4#

(Took fifteen minutes.)

(Would be helpful if we could press "Enter" and get a line break; then click on a button to actually post -- and if the formatting didn't change when you clicked on it.)

dsymedia, Agree about the line breaks- annoys me, too. When numbering, however, you also need to delete the space after the period and before the move notation- it treats those as bullet points for paragraphs and restarts the numbering after each.
