Interesting Game

I played an interesting game yesterday. I was black and I somehow managed to get a ko threat which forced white to reduce his own liberty. I commented the game. Feel free to drop some inputs.

Here is the game record:

Hi, Biondy.
Why doesn't white go to R17 instead of N17? Btw, I want to save ur game but I can't coz the link is already dead.

White can play R17. Black will play M14 as the answer and the big white group in the center is dead. White plays N17 so the groups are seki.

Ooh... Maybe it was deleted. You can enjoy the review only via my blog then :)
