;W[df]
;B[ef]LB[fb:B][df:A]C[Black e14 has a somewhat negative feeling to it: black allowed white to strengthen his left-side shape for free.

This was a good opportunity for black to make a counter-challenge with B. See variation.]

;W[eb]LB[df:A][ef:B]TR[dc][fc][dd][ed][fd][ff]C[The general impression is that black has been forced into an overconcentrated shape in the upper-left corner. The A-B exchange has become especially bad for black.]

;W[gg]LB[hc:A][fd:B][de:C][hg:D]C[Since neither white A nor black B is yet completely alive, it is valuable for both players to develop their groups to the centre.

However, since black is not in danger of dying because of the spare eye at C, it was probably better for white to play the more solid move of D instead.]

(;B[kc]
;W[jd]
;B[ke]
;W[je]
;B[lh]LB[pf:A]C[Black m12 is a gamble; as white has more solid territory in this game, black has to try to get as much as he possibly can in the upper-right corner. On the other hand, if white now manages to live easily inside the black moyo, it will be almost impossible for black to catch up.

Something like black A instead would have been more realistic, but in that case the black territory on the right side most likely would not have been enough to challenge white's territorial lead.]

;W[pg]
;B[qh]
;W[lb]
;B[mc]
;W[oc]LB[lb:B][qc:C][pg:A]C[White follows a kind of bean-scattering approach to invading the black framework; white A and B open up weaknesses in the black shape, and force black to handle his own weak stone of C. While black defends, white plans to play sente moves that help his own group live.]
;B[nc]LB[qc:A][pd:B]C[Black o17 plans to make the black A stone live in the corner separately, but that ended up giving too many forcing moves for white. It appears that playing the usual move of B was better; see variation.]
