Hi mongus,

Basic shape.
Hane at the head of two enemy stones.

Your notes here.

is not a good move, nor a good idea.
The situation is not as you think -- it's an opposite of it.

Bad habit.

Tenuki and Turn, very good!

Your P18 stone is very light (small) --
you can easily discard it if necessary. No ladder problem.
You can think about how to attack this

stone for profit.
( Or, you can think of other ideas to keep your lead. )

Not what you think. Your game move is OK.
Your

variation is bad.

Slow. ( Your notes: not what you think. )
Can you find any better local moves ?

You get confused when there's contact fight.
What are you trying to do with this inside-hane ?
What's wrong with just hane on the outside with o12 ? ( To profit the right side. )

Bad habit, bad instinct. You bump your head into W; you reduce your own liberties.

W can P14.

You're trying to remove his eye at N13. However, your move at M12 is not the only option.
Did you see or consider the other options ?

( Your notes here: Not what you think. )
You don't have to kill W to win this game.
All you need is end up with 0.5 more points than W.
Up to here, you played some misplaced stones, but overall, Black is still way ahead.
Just count how many points W has, and look at the whole board.
You can profit on the right side; you can profit on the left side.

Lost track of what's happening (confused).
W is not alive yet. You are happy to continue to reply --
example, P11, to continue to profit your right side as you attack W.

(Same note as

). You must take care of your top right group. Q11.

R11.

W is confused (

); he gives you a chance to connect up,
but you miss it. R11.

Lost track of the board.
On

, what were you trying to do with this move ?
When W ignored

, why didn't you follow up with it ?
For example, instead of your

, did you see you can cut off

completely ?
