There were two points in the game where I had sente, and the best move escaped me. On both occasions I feel that the game changed because I didn't play the right move. Any advice is appreciated - I've marked them in the file, as well as a couple of other points that I found noteworthy.
This is an easy shape to learn, black to play and kill:

10: Seems like the correct reply. White has to do something to take advantage of the weak group. After he plays j17 you can R15 or S16. 69: You need to think about what you want do with the group, where can you chase it to get maximum profit. I probably would of played somewhere in the aread of J9 to get a large moyo.
96: Yes, you can still attack k10 group.
I have nothing helpful to say about the other points you mentioned.
Thanks for the pointers. Man, that kill looks so obvious now! My brain was telling me it should be killable, but I was getting low on time, and just couldn't see it.
