;B[cn]BL[1477.128]C[Was this good or would have been F17 better?
I played this because I wanted to prevent my opponent from making a double wing shape.
*** You cannot say that this is bad. But see variations.]

;W[jr]WL[1331.446]
;B[lr]BL[1432.355]C[I felt uncomfortable when I played that, it looks too small but I wanted to avoid White from slipping in.
*** Yes, it small. As for White slipping in, remember that it is difficult to make territory at go. Better to make it during skirmishes.]
;W[bp]C[*** This is big, since it secures territory while attacking.]WL[1304.891]
(
;B[an]BL[1425.173]C[The same as move 19, but here i misclicked and played it on the first line, is it bad?
This move looks important now because the group will lose it's base when white slipps in.
*** Yes, it is bad. The time to worry was earlier. As for now, see variation.]
;W[en]WL[1290.491]
;B[dm]BL[1421.82]C[*** Too defensive. The jump is still better.]

(
;B[md]BL[1383.004]C[Here my plan was to build influence to the center, and if white cuts i thought that by pushing in white will lose it's base.
