Joaz took us up to 100 so I'll continue from there.
105: Not so good. Aji keshi: you remove all possible threats against the group (s16 atari, s15 placement), which removes ko threats and reduces endgame possibilities. Removes a liberty: now you have 4 liberties, and after Wn12, you would have only 3 liberties. Doesn't strengthen the connection between your stones greatly.
113: Did you consider any other moves?
117: Aji keshi for similar reasons to 105. Now he has nothing to fear if you play f3, for example.
121: Not sure I agree with your assessment that the left side will be small. You can aim to prevent W from living locally.
129: Note that you have urgent shapes both at D7-8/F7-8 and at G3-4/K3-4. In either case, getting the first move locally is hugely important for either side.
141: Yes; push enemy groups away from your weak side, towards your strong side when attacking. Push them away from your strong side, towards your weak side when sacrificing.
161: Small move, G8 and K3 seem bigger.
166: This is a mistake from W, but that doesn't mean that exploiting it is the biggest thing on the board. Both the B groups and the W groups are completely safe.
207: Not important. You have equivalent options (
miai) at J5 and N6. Cut at M7 and try to capture 8 stones.
209: What is your thought here? I would say either J9 or a move like D10 is urgent at this point, depending on how aggressive you want to be.
211: Can you see why J9 is worth more than capturing one stone at L10?
213: Sacrifice K9 (and L10, if need be: wall off the left with H9, H10, etc.
215: No need to recapture. You don't need to reply to every move your opponent makes. Trying to surround the left side is more important than one or two meaningless stones in the middle.
217: Try to determine two things: (1) Did this move affect the life or death of any groups? (2) How many points did this move make? (3) How many points would a big move somewhere else have made?
247: This is only 2 points.
259: You need to play at D13.
262: Ah, okay, I see you figured it out for yourself.
264: This is wrong for W. He needs to play at A16; then the entire group might die, which is worth a lot more. (B must resist A16 by playing D14, and then there is a ko for the life of the group.)
