Move 22: You CANNOT connect in empty triangle here. R3 is the small avalanche joseki (I personally had to look it up, though :p). I wouldn't play 18 at Q4 if I am not comfortable with at least the basic avalanche variations.
Move 26: This loses points and ko threats for no reason.
Move 28: The other side seems better, here a pincer works really well with the lower right.
Move 30: I would consider extending without keima here because, again, the pincer/contact at R13 looks good for black.
Move 32: This is joseki, but the solid corner you get as a result doesn't seem that great in this situation due to black's upper right being fairly safe. Black's extension from 2 seems like it works decently with the lower right. I would consider a pincer instead because of the C8 aji.
Move 36: This seems to leave some weaknesses behind (aji later at E17/F17/G15/H17/etc.). E16 is apparently joseki here, but black being solid on top right makes it not that attractive imo.
Move 38: Feels a bit wishy-washy with no obvious local follow-up/threat. After 39 the game looks desperate for white.
Move 40: The sequence starting with this is too painful for words. There is no good invasion around there unless you have more support first. Invading now and solidifying your opponent loses the aji.
Move 52: Seems a bit aji-keshi, but I guess white doesn't really have better moves locally anyways, so not a big issue.
Move 55 is very very bad for black.
Move 57 is small and a bit boring. I think white should ignore. And then the sequence that trades second line for third line is unnecessary and painful.
Move 65 is big, white answering makes it even better.
Move 67 is questionable as well.
Move 69 is the same mistake as white 40.
Move 70: Giving black a ponnuki here is way too generous. I'd consider either N3 or O5 here.
Black should capture at 75.
Move 78: Seems like an important point
Move 82: Seems like overplay. Hane on the other side.
The sequence that followed turned out really good for white because black let white ruin the entire area. A move like D8 or D9 before would leave white in an awkward spot, I think.
Didn't look at the rest of the game too carefully after. Move 168 is nice feeling, but doesn't actually work as far as I can see.
, let's have some fun in the tournament.
