Hi Martin,

First kick at R5, then jump to O4.

O4. You need to fix your shape. Re:

.

O4. You missed this vital point 3 times in a row.

By now, you're already very confused about the situation.
Let's go back.

W jumps into your sphere. Locally, B has an advantage.
B can pressure W; it is W (not B) who should be under pressure and defending.
If you kick W on

at R5, W extends to Q5 -- now W is 'heavier' (a bigger burden than the single stone

) --
then you jump to O4: continue to pressure W.

Already confused. Fix your shape at O4.
W cannot link up

to

-- you continue to split W, attack W.

W gives you a chance to finally play O4...

...but your thinking here is "just to stay in the corner".
This thinking and this exchange

-

are both not good.
For one thing, you still have a weakness at R3.

W hits the vital point.

R4. Study the continuation.

R1.

S8.

Wrong shape. K17.

Connect -- then

C11 is not atari.

Slow.

is thin -- did you consider to cut him off and fight ?

Q17. Your R16 is kind of similar to

--
you didn't think about to cut off W and fight.
Even if you want R16, you still block at Q17 first --
then, when W hanes at Q18, then you have a choice.

P16.

Good.

R9. A recurring problem: you don't think about the strengths and weaknesses of your enemy groups. Same problem with

: you didn't cut off

. Same problem with

: you didn't think to cut off

.
Here, you didn't think to cut off W with the hane at R9.
W can just connect back (e.g. R8).

Same problem. Why didn't you think about killing W -- starting with R9 hane ?

...

Confused. All you have done is force W to link up everything nicely,
AND you ended in
GOTE.
Think about sente and gote.

Strange. Locally, these are better: G15, or E17, or K18.

Why. Do you see that even with

, you are still not alive.
So

does
not help you live -- W can play J19.

101 Confused. W made a mistake ( missing J19 ).
You can live immediately with J19. Why not ?!
