(;W[dm]C[A bit too slow.
I was afraid of moves like C7 and D7 if I go out faster, but 
a) C9 is too weak to counterattack directly
b) My group can live locally rather easily

or I can even sacrifice my 4 stones!

So instead I can in fact play E7 or maybe D8]

(;W[db]C[I meant to keep black weak and attackable, so I have two weak groups to attack.

The trouble with that though is, that I also create weak groups for myself, making it hard to profit from attacking!

Instead better to just take a big corner and connect my stones with D16!]

But I can jump to J12 instead!!]

(;B[id]SQ[ec][hc][kd]C[E17+H17+L16
Two two space jumps, be it all low, all high or mixed like here, always leave weaknesses behind.

This black move helps white to fix them for the most part!!
Very bad exchange.

Instead black can go to J17!]

Instead better (what I also considered during the game) to back away one more to J6!]
;B[kl]

;B[kk]
(;W[mf]C[Too greedy, starting to lose control in the middle!

Once again, not being confident to score enough points, I chose to play greedy instead of staying in control!

Instead M12!!
(I also considered this during the game and remember thinking, that this is probably the better choice - still gotta follow through with that instinct!!)


The gain I have from this game move is less than the gain I can have by keeping up the pressure in the center, which will allow me to enter much deeper into the right side!]
;B[kg]
(;W[lh]C[Once again wrong direction, damaging my weak group even more.

This move also has too weak a connection with N14.

So instead better to play M11!]

I also considered to play G2, but J2 is just as good and my counting told me I was ahead, so I chose the simpler option!]

Luckily I had just gotten a new Byo-Yomi period, so I used nearly 2 minutes to make sure black can't cut me off on the left side after I take E6.

(I wanted to be sure that I wasn't hallucinating liberties and lose the whole left group . it happens... ^^)]
