I don't think he is 4d, but again we played each 130 moves in 10 minutes... Lots of garbage in there (move 106 for example) but since it was kind of a blitz game, I'd like to see what are my bad reflexes/automatism/habits

Some "reflex" moves that occur to me: B8) P6 or O5 to enclose W and cut off his access to the center. The sequence O5-P4-P5-Q3 would sacrifice the P3 stone for a fine result. B16) Q8 to defend the side, now that W is thick. B26) B9 or E9, hane at head of two stones. B30) F11 stand (although the game move is also good) B36) B14 connection B44) F16 to defend the side B50) F17, extend rather than atari B56) Anywhere else (too close to W thickness) B58) P17 to defend the corner. Treat the two side stones lightly. |

Some different ideas about the sequence starting at move 48. In the game, Black played hane on top at H16, which I think is a good first instinct against an attachment. The other common option one needs to consider is to extend, for example like this: It seems like this would be stronger, as White can't really avoid being cut into two eyeless groups. A few moves, later, we arrive at Here, I think it's worth pointing out that the  /  exchange should be omitted, as it doesn't help Black. This is what Charles Matthews calls the 1-2-3 principle. There's also the proverb "an unnecessary move is a bad move".One move later, I think mentioning broken shape in this context is a failure of pattern matching. This shape even occurs in some joseki, and Black often has a tesuji involving a double atari which is worth learning: It seems to me that this would be playable in this game. White can't really afford to start a ko since Black takes first, and winning it would pretty much be sente against the whole eyeless white group: |
