Please come with some feedback. How difficult is it? There should not be any alternate, non-inferior solutions.

Wow. I've never seen anything like that before! And I thought anybody would be crazy to promote to knight!

Its all too easy to promote to Queen, in crowded positions a Knight is always worth looking at.

i love it

Up until the queen sacrifice, I wouldn't have been too impressed. But finish that was purty.

The first move is very obvious, but since it's forced from that point on I included it anyway

That's awesome.  Great post.

Since the black is forced to capture the queen with his rook,because he can't move his king away,there is nothing else to do.

I was thinking of promoting to queen and didn't see the double threat using a knight.

Very nice ending by the white.

I have promoted to a knight 1 time and the results were the same. It was an otb game and the look on the guys face was priceless. Not something that you can do all the time but so much fun when you can.

Great to get so much positive feedback. It is always fun to hear that what I do is appreciated. Should I consider to submit more puzzles, or even put this one in for future puzzle of the day?

ABSOLUTELY. nice to see you here by the way Cuendillar.
