C[Trying to settle on the edge.];W[qk]
C[But white follows my move and fights everything.];B[pj]
C[I thought there is no way white can live ... and if he does I get some nice outside influence. (What good that can do me?)]

C[Next target for white...];B[ee];W[cf];B[ic]TR[hc][de]
C[I cannot see any direct threat, so I extend and try to make a base. Maybe went one step too far here?
Also considered D15, but it felt overconcentrated.]
;W[de];B[dd];W[ef];B[fe];W[hd];B[lc]TR[ic]
C[Not intending to fight the "invasion", instead making it possible to live separately if need be. Also strengthening the J17 stone in case of a fight. Maybe one space jump would have been better.]
;W[od];B[ie];W[he];B[hf]
C[Possibly too aggressive. Should probably just yield and give the outside to white and live small on the edge.]
;W[id];B[je];W[jd];B[kd];W[jc];B[ib]
C[This is so counterintuitive to me, but happens over and over. White stones has NO eyes, cannot run and still wins the fight, and black ends up dying badly.]
