Life In 19x19

I recently hit 4k on KGS again and here is my first even win against a 3k. Even though I won (there was a huge capturing race when both players were in byo-yomi), I think White made many mistakes which could have been avoided (in the last fight, White could have ignored some of my ko threats or played a double ko I think).

I have written in some of my own comments/questions and would really appreciate some insight into the opening and the fight starting after move 197.

I played Black by the way.



Thanks!

Move 11 is wrong if you weren't aware that white has a weakness on the top right (and probably even if you were). And 13 makes a funny shape on top (too flat).

27: I think B14 or C14 is the shape.

White missed a big chance at 112, I think he can throw in at q15 and capture everything.

Ah, those were just the comments I was looking for, especially regarding move 11. I will have to pay closer attention to the "flat" shape in my openings. Thanks!
