;W[cg]C[I hate it to be pincered, because it forces me to play for the center, but well... here we go..]
;B[ee]
(;W[fc]C[Seems to be a bit passive of my opponent.

Dusk: Yes, it does. I can only find one pro game with this move, compared to 446 one space higher and 92 games at G17.]

(;B[dj]C[This was the first point where I struggled hard to find the best solution I pondered for several minutes to play this move. A few variations that I read out seemed to be inferior for black.

Dusk: At this point, this is the only move, so it's good that you played it. It would be very bad to play D12 and D11 only for white to end up getting a hane at D10.]
;W[ck]
;B[gd]C[The idea behind this move was to attack the white group at the top and expand my moyo potential.

Dusk: This is something I could be wrong about, but I don't like this move. If you were going to do this move, I would've prefered not playing the D12-D10 exchanges. That way, after you built a wall with G16, you could come back and pincer C13, rather than shoulder hit it. Instead of this move, I would've defended my weakness by playing D13.]
;W[gc]
;B[hd]
;W[qf]C[My opponent was the first one to play elsewhere, but this point looked as if she tried to pincer herself. I cannot say whether the direction is correct here.]
(;B[qh]TR[qk]C[Double purpose move: attack the white stone while making a base.

Dusk: The triangled stone doesn't need to make a base, as it's not pincered on the other side. Instead, it was functioning as a soft pincer on white's last move. So this move is redundant. Instead, you should utilize the fact that the triangled stone is already a pincer.]
;W[of]C[Dusk: This is a hard way to play, as black's R12 stone already has support at R9. Taking the corner might be simpler, but J17 is also still very big.]
;B[nc]C[Take the corner calmly, knowing that the white stones are still vulnerable.

Dusk: I would play high, in preparation for blocking at H17.]
;W[rd]
;B[qc]
;W[rc]
(;B[hc]C[The idea behind this move was to make territory at the top while attacking the white group at the top left.

Dusk: Good! But notice how O17 would look better at O16 now]
;W[bd]
;B[mf]C[I preferred this over taking the corner at s18. Certainly the corner is big, but it would have ruined my plan to build up a moyo.]
;W[ph]
;B[pi]
;W[oh]
;B[mh]C[Continuing to build up the moyo. This move looked very big to me.

Dusk: But since you're going to want R13 soon, it may be better to play it before you force white to take P11.]
;W[oi]
;B[qg]C[This was another crucial move. It took me six minutes for this decision, but I could not read out everything. Looking through the variations, it seems to have been an overplay.

Dusk: See modified variations.]
(;W[pf]
;B[pj]C[protecting the cut seemed essential.]
;W[ij]C[Excellent reduction move with the right timing. I was a bit annoyed and pondered about which is better, to capture the stone or to secure the territory.

Dusk: This isn't a great move at all. Did white forget about this weak group?]
(;B[ih]C[I decided for the secure variant. Still seemed big enough for black.

Dusk: Very very passive. See variation.]

;W[ki]
;B[jj]C[broken shape for white.]
;W[kj]
;B[mj]C[Avoid the connection of the white groups at the right and the center. If white played k9, there are sill cutting points to exploit.]
;W[jk]
;B[rf]C[This is an attack to split the white group and a sente sequence. I had aimed at that when I played at n10. This move also denies white an eye at r15.]
;W[re]
;B[rg]
;W[qd]
;B[qb]C[calmly extend. White can make only one eye for her group.]
;W[rb]
;B[ra]C[With this move I wanted to keep the option to deny white an eye in the corner with t18, for the case she could still make an eye elsewhere.]
;W[od]
;B[oc]
;W[me]C[It seems white wanted to play a shape move, but to me it appreared to be an overplay.]

(;B[nj]C[Dusk: Can white find two eyes inside? Probably, but this move will still have him completely surrounded in sente, and once he's made his gote life you can turn and proceed to attack his J10 group. You'll also have moves like P4 in the wings to make a large area on the right side. End of comments.
