hi! about move 7

i can't recognize it as mistake by black. it isn't joseki-move, but… why not? imo, it's a hamete: "i invite you to reading-competition right now. forget all this ancient stuff about joseki and try to beat me!" :)

and result is unclear for me: move 20 is gote, so black got:
1. ≈10 points in corner
2. sente to reduce potential of your wall (Q7 are freaky, but something around Q10 are nice for black, right?)
3. potential cutting point @M4 (ladder works? ok, more-less free ladder-breaker around D14 than)

you have:

1. nice wall
2. almost surrounded(= useless) black group in corner
3. nice 2-sided extension from it

equal exchange?

move 22 is strange. Q7 too close? it means "Q7 weak. i can attack it with pincer and force him to live in pain or run in panic!" :) what if black's 23 will be calmly @R14? Q7 became not-so-weak (how to pincer it without creating your own weak group?).
so i prefer to accept invitation and go to Q10 or maybe Q14 instead

Thanks, ...
i still think black 7 can be called a mistake ...when it comes to hamete i go with the definition at sensei libary:
"To qualify as hamete, the trap must be challenging--it needs to be something that could deceive even a dan-level amateur."
...but in this case i think white8 is kind of "easy questionable" (and white 14 as well maybe not good) ... the point is i think a dan player could answer without falling into this "trap" (hamete) easily.

Yes, white 14 is not very good ... for black to play at Q10 is big (even freaky Q7) ...

Yes, white 22 is questionable ... i think you are right with Q14 ... :-)

agree. hamete and this kind of moves are not the same. in my opinion, difference is "hamete = i know i made a trick move, my risks, my decision" and moves like mv.7 are "i don't know classic patterns there, so i try to invent something by myself, reading competition between us starts"

"mistake" in my own terminology is "ho! i know what to do with it! and i can gain some profit without doubt"

so it can be mistake, yes. but it's relative. my own rule now (after tons of wrong decisions :) — if i can find right answer then it's a overplay, if not — proper move (until i'm in search of solution)

about move 8… i prefer O4. more-less same result, maybe a bit more stable. (btw kgs.fuseki.info has some variations of this pattern, you know?)

move 14 is "only move". i don't find another way without creating broken shape

and last small opinion: move 16. you can play double hane @L2 instead. difference is: a bit more solid shape for w + one ko-threat
