;B[nb]

;B[de]C[Not an ideal approach to the 3-3-point.
It is a bit too close while not touching yet.

A better choice would be C14/D13, D16 or G17!]

(;W[ql]C[I was in an aggressive mood, wanting to test my opponent as soon as possible.

However my top right group is also not that strong, so a simple slide to S9 was probably a better choice - strengthening my own group while undermining the base of the black group]
;B[qk]
(;W[pl]C[Wanting to fight really badly.

Instead I have a neat move to threaten to connect to either side: S7!]
;B[ol]
;W[rk]
;B[ok]C[The kind of play I was waiting for.
Now I gained a little bit, compared to just sliding to S9 initially.]
(;W[qj]C[However this was an inexplicable mistake.
I fix on the stronger side, making it harder for me to make use of the weakness around P7.

Instead I need to connect with better shape at S7!!]
;B[mo]
;W[lp]
;B[fq]
(;W[cg]C[This move shows a lot about my inexperience still.

Despite the top and right side being better for me, after my opponent took F3 I got nervous. My opponent hadn't messed up majorly yet and for some reason I didn't feel comfortable with this position.

Instead of just continuing calm and level-headed, I started to try too hard to make something happen on the left side right away. Only trouble with this is, that C13 and my next move are both not really hard to answer, so I'm not really forcing my opponent to mess up, I simply give away outside for no reason.

Instead, I should have just 
a) continued where my opponent just tenukied and trust that I am right about M4 being a good move (e.g. wit hL6, which was my first instinct in the game!)
or
b) Come from the outside with e.g. G14, putting pressure on the D15-group and threatening to invade at e.g C9 next!]
;B[dg]
;W[cm]
;B[dm]C[Too easy to respond.
Now I gave black two outside moves and...]
;W[mm]C[That severely limits the effectiveness of this attack!

That being said, this attack give black too easy counterplay.

LESSON: ATTACKING DIRECTION and cutting

The 4 P8-stones are not easy to cut off even after black ignores that area and plays at M5! (because of R10 not being at S7), but even if I do cut them off, my stones in the middle are not very strong either, so the question is what this attack can really gain me.

Instead locally I should still attack from the bottom side.
Globally, I should probably continue on the left side now with D8, C8 or C12 and then trust that I can reduce the center efficiently afterwards.]
;B[lo]
;W[on]C[I wanted to cut - so so much]

;W[om]
;B[kp]
;W[lq]
;B[kq]
;W[ko]C[Still trying so so hard, but especially with the left side exchanges made, this is more dangerous for me - instead I should probably just tenuki and return to the left side now!]
;B[lm]
;W[nl]C[Not putting on pressure.

Instead much more active ways would be to play moves like J3/J4! or even just K5 or M8
