Hi Cynosure,

bad. Probably one of your bad habits -- this kind of contact. For example, better at R5, kosumi.

-

locally, you first make a broken shape for yourself. See also
Toothpaste .

strange. Why not turn solidly Q8 ?

similar shape problem as

-- White would push at D5, making a broken shape for you. See also
Elephant's eye .

Loose. Did you consider either atari C4 or atari D5 instead ?

same bad habit as

. For example, better at C15 kosumi.

wrong shape. The proper basic shape here is extend up at M4, not drop, because then you allow White to take the good point M4.
M4 is the shared local vital point of this shape.

White also missed the vital point M4.

eating junk food -- bad habit. The 2 White stones at Q4 are too small. Nobody wants or cares about them, at this moment in the game.

mistake. Why ? You study this shape and figure out why this is a mistake.

bad shape.
Up to here, you can see most of the mistakes for both B and W are basic shape problems. Not direction issues.
