Knight's move puzzle

www.youtube.com/watch?v=K8N6_tVI1Wk

Fairly easy chess puzzle. Experienced players will get it very quickly, but you may enjoy it even if you only " know the moves".

White to play, and he can lock the black K and P up by playing to c1 or c2. But one move draws and the other loses. Which is which?

Once you have worked that out for the initial position, see whether you can work out the rule for drawing no matter which square the knight occupies to start with. Don't just guess — prove it! The general discussion starts at about 5 minutes into the video.
