11: You want to attack that stone? You'll do better with F17. Not only will it be safer when it hits the wood, but it is a long extension off of Q16.
37: When attacking, force him into your strength, like a hammer smashing something against an anvil. You are strong on the lower side. Make him run into that strength by pushing him down from the middle with L8.
Playing L6 just pushes him toward the middle of a somewhat open board where it will be much harder to trap him.
41: Again, you are pushing him away from your strength. M7 cuts off his access to the center.
49: His two stones are heavy, and they cannot make a good extension because your K17 stone is just where white wants to play. They are heavy and short on eye space, so attack them.
Q14 is the attacking move. R14 is territorial.
53: Hane at N15.
63: Hane at B18.
147: You play E17, he replies E16, you throw in at A19.
I think that you get a ko for life.My overall impression is that you made virtually no bad moves for 9K, just a lot of timid moves. Work on your attacking techniques ( force him toward your strength, hane more often, etc ) and you'll be two stones stronger in a week.
