C[This kosumitsuke is strengthening White, if no Black stone is around Q10.

OTOH, if a Black Q10 is around, it is a fine attack, making white heavy (before making ikken-tobi o16). White misses then the ideal extension.]

C[I am always in for some fun.
I rather like to lose an interesting game 
than to win a dull one.

As a <b>comment</b> for your last two moves:
-only playing m2 is better,
-the <li><font color=red>vulgar atari </font>
 (you heard this term many times from me in the course) only strengthens white a little bit,
as a <b>guideline:</b> 
-if you cannot capture something due to the atari or have another very special reason for atari-ing,
<li><font color=red> don't play atari!</font>

Of course, there is also a downside for me: if I lose these stones later, I will have lost 2 stones instead of one. However, as mentioned before, I do not see an immediate capture.

Concluding: white has profited a tiny bit (aji) by this atari.

If you were always avoiding the <li><font color=red>vulgar atari </font> your playing strength is raised dramatically.

C[Your move is indeed the most interesting for both players.

It might that some other quite move by better players is even better, but this move poses White some problems.]
;B[po]

C[What a pity!
Blocking at Bp5 here had some really interesting variations, which were feasible for Black.
There exists a tesuji which prevents the ladder 
(Bp5) Wq5 (threatening white's ladder Wo6)
Bs5! Ws6 (threatens ladder again)
Br6! Wq6
Bq7! .... (White was always forced and Black would have avoided the ladder in sente.

If White then wanted to live in the corner,
another ladder could appear on the outside ...
and White had been lost. (I'll show you the sequence later on the board).

OK, with a 6 rang difference you prefer the safer play, which is not worse at all! Good play!

My Wr5 was purely experimental & for fun.]

C[Attaching at q8 was indeed much better than cutting at r9. White had squeezed around white r8 and sacrificed the stone to give black a false eye.

Your move here is much more dangerous to white, as I have to decide, do I want to confine Black by Wq9 (now played) and go for all?

OR, do I give in and play Wq7 instead?
Wq7 qould mean that we could exchange (me the group and you the influence (Wq7-Br9 atari, Wr7 connects, Bs10 atari, Ws7 blocks (the black group is then captured) and now e.g. Bq9 connect (NOT Bt9 ponnuki), IF then White were playing Wt8 capture you simply hane Bq10 and stay globally gorgeous (IMO).

I see now several variants which are good for Black. The fight is not yet lost!

This comes because the White p-line-group will lose liberties while attempting to separate black and capture black. But as a group alone, White is killable too, hence a semeai develops, which black could win.

However the black O-line group then only has 4 liberties left too ...
In order not to be captured in geta (e.g. n9) Black then has to find a move which prevents this geta in SENTE before (i.e. White would not like to lose her mn7 and mn5 stones.
Sometimes an attachment at Bm8 is a tesuji (enabling damezumari Bm6) ...

Now , that where enough tips.

Remember, you are not lost until the game is over!
The way to get better is as the way to win the very game a struggle - try to achieve some partial goals fight for liberties, sente, shape, exchanges etc.

Don't give up!]
;B[ol]
;W[pm]
C[Very good Levent!

Even without looking at my comments, you make the correct move with the correct reasoning.
 
BTW, you won't lose! You'll win a lot of experience with this game. Forget the aspect of winning for this game and play your best moves as now.

Your move Bq8 here is indeed better than the Atari r7 ff which I commented upon.
This is for your given reason that White could play then p8 herself and get control the center (Bo4-8 gets weak). Black would only live. Correct.

White (I) would not continue with Wk8, but something more prosaic, tight & safer Wn9.

So - for teaching reasons - my White moves here are not correct, because I am not convinced that I can capture Black AND keep the white mn5-7 stones. The white corner also only can live with another move. Where my moves premature?]
;B[qm]
;W[qk]
C[As said, there is a live making move now!
(Expand eye space), my previous analysis was flawed.

Still there are decisions to make:
1) if you live now in Gote, White can easily catch the black o-line group with a geta Wn9.

2) Or, black extracts the black group first with a sente move against some or all mn5-7stones.
This is likely a liberty-reducing move:
e.g. Bm8 threatens to capture some or all mn5-7stones AND
-no matter how white answers, she cannot directly capture Black in geta anymore.
Black could then live as in 1), whereafter White lives too. Black has SENTE!

There is a drawback i) however and a consideration ii) to make:
i) White could capture the black o-line stones (*) later on a bigger scale. OTOH, these risks always exist :-) 
ii) White could chose to accept the loss of the 5mn-stones  and try (!) to capture the black right edge stones,
ii-1) if white were succeeding, you made already a comment that the center would be more important. I agree with you: With the loss of the white mn-stones, White would also lose the attacking potential vs. the black o-line-group.
ii-2) if White is not succeeding (because the White edge group can also be killed) - too bad for White.

LEARNING
Levent, what is now the important essence to learn from case 2ii-1 ?
That is is not bad to lose stones! (if you get something else in return. That could be points, another group, sente, aji, attacking impetus etc.

Trying to understand the meanings and examples of furikawari, sabaki and shinogi helps us on this way.
It's like being able to catch the tail of an animal (snake?), but it turns behind you and still eventually bites you.]
;B[nj]
;W[lk]
C[Your Bo10 is a very good move.

Bm8:
And attachment Bm8 would have been a very good move too, ensuring that the black center group can come out.
If white replies with WL7 (Black tenukis) or hane WL8 (Black replies, but ends in sente),
I have not discovered white moves which capture Black. 

White's move Wm9 here wants to prevent the strategic geta-like Bm8 (White would be captured).]
;B[os]

C[Why did White not play S7?

White did not overlook it ,
but tries something else,
not sure whether it works - many moves involved.]

C[\[1\]
Again, as a remark concerning style:
just playing ...(any of your next moves!)... is as good as this atari here.
You do not need an atari now - LEAVE IT OUT.

There are few occasions where you really need an atari - in this game White played 4 of them e6, b7, m3 and m5.
Of your 3 ataris (m4, r7 and now n12), your 1st and your last were superfluous. Even worse, atari Bm4 initiated and enabled all of this now.

Imagine, there was a ko fight to come (I do not say that there is), then you had lost now 1 threat, while the move you probably want to play now would threaten double-atari anyway.

These type of hane and multiple-hane fights occur several times in each game. That's why knowing this easy lesson (Atari, atari - vulgar play. Don't do it!) 

Now, I do not want to patronize AND I told this several times already - apply it !

With the options and aji you retain, this brings you 1/2 stone strength increase at least.

\[2\] On the other hand, if you want to get control of enemies stones, do so as firm as possible. This could mean, that if you have a choice of (i) taking stones out (defintively removing them from the board) or (ii) just getting some minor advantage (e.g. some couple of points more or so) but NOT removing them, THEN option (i) is much more favoured by professionals (no aji, no ko threats left, eyes etc.).

I am not sure, yet in our game q6 could have been directly on r6 IMO. Ina way, Black used eventually 2 moves Bq6+Br6 to atari Wr5, hence not so efficient.
But, as said, I am not very sure, there are always 2nd considerations.]

C["Auf s13 kann ich ja leider nicht gehen :( "

1) You had to check out also the variation 
Bs10 (1 eye) - Wt10 (snapback)
now your atari Bs13 - Wr10 takes 
Br13 connects or better still Bs14 
(if White wants to cut now, she must do so with an empty triangle Wr13, in fighting, an empty triangle is very bad. Then there is the cutting point around p14. 
I calculated this. 

(2) Secondly there is the throw-in tesuji at W09.
Usually I had played this already way earlier, because it loses Black many liberties in W-sente, if he captures Wo9 with Bn9 or Bp9 and is subsequently squeezed.
However, Black could answer here with Bn8, which threatens the damezumari tesuji Bm6 (if Wn6, Bm8 moves out). 
White cannot allow this and must block Bn8 with Wm8. Then Black could make an eye and white would lose a liberty.

Because Black could play at any time Bn8 himself and then have the Bamboo liberty problem, White refrains from doing something now herself.]

C[White's previous move could also have been at your last place q12. Usually this is a very good throw-in for damezumari purposes. However, I thought that it is not good here:

i) (Wq12) if Br13, then White cannot press from Wq13, hence must play this actual move Wp11 (captures black q11) anyway. However, I see now , that this would mean that White still could safe her  4 stones opqr14 (or black loses sente at some point) ! This is a difference to our sequence, where White loses sente and the 4 stones are definitively gone.
A stronger player than me had seen that - 10 points equal one rank.
I erred here, because I thought "anyway I capture the imortant tail". In Blitz I simmply had thrown in.

ii) If Black starts a ko at Bq13, this might actually help the other white positions. 
Also, ko-wise there is the chance that white survives with the 4 stones.
White still could have got the important Bo4-8 tail of the black group.

Thereafter, Black is still ahead by about 50 points AND Black has sente !!!]

With the use of ko threats, black might be able to play then e.g. e13+d14 and take some side territory.

The black move d11 is too "plump", around ef12 are either false eyes OR black is sealed in - not beautiful prospects.]

C[The more "normal"-looking eye-stealing Wb10 is gote for W after Bb9.

Hence, anyway I had to return to the upper corner.
If you have an eye at c11, then W rather tries to protect the cuts on the 8th line.

Perhaps there is a better way (ko?) ... but I do not see it?]

;B[dc]
;W[gf]
C[What a pity, White took gote.
To get sente (and get to play in the center) or capture some stones around e14 WITHOUT collateral dammage is perhaps to much of expectations.

Actually this comment is for one of my next moves. It is very difficult for me to decide between san-san c17, kikashi (aji-keshi?) g14 , indirect ladder-atari h16 or so.

One of White's most wanted moves is to bend around (motare ?) at g10, but without preparation, Black simply captures the corner.

So much for teaching strategy - it's mostly a lot of questions which you have to ask yourself and evaluate, try and dare.]

C[RE: 
No, 
I don't think that you did commit a specific mistake somewhere.

(1) Only: your atari bH5 let me leave the lower situation eventually in sente, having got virtually 2 eyes, less need to worry about a later semeai with your - captured but not dead . bD11-group. 
Giving me sente could be called a mistake. 
I expected simple nobi bH4 instead.
I was planning for a later wJ5 aji .... but that only would have been later.
With your sente you could have reinforced the top.

(2) Your cut G16 at move 136 was most probably on autopilot. However, this are the situations where one can explore many alternatives. 
bJ16-wG16 (connect) - 
bH15-wG15-
bH14 would have lead to very interesting combinations. I was confident not to die rightout there, but to achieve a favourable semeai ...
Afterwards there were alternatives too - we had to discuss these once on a board, too much trouble via text. 

Before we talked about the game situation in general. Of cause Black is/was ahead by 20 points then. But one cannot say all territory k-t/17-19 is definitely Black's (neither for White's). Go is too complex, there are many possibilities which I don't see either.

My move now ?

C[There is this fine line between genius and crazyness (Genie und Wahnsinn).

I think I crossed a line.
Perhaps that one between stupidity <-> craziness.

In the end I don't know what I expected.

;B[rb]
;W[nb]
C[No no, I simply messed it up.

There is no special tesuji, I only see sequences with dead white stones, if you do <li><i>normal</i> moves.

I correctly thought that I was behind, but still then my invasion was premature and bad. 
If you had replied at e.g. Bm17 Wk18 had been cut-off without bad aji against Black.

Somehow I hallucinated that you might reply to my invasion at san-san (even then my invasion was bad, "shit happens").
