;B[dr]LB[jp:A]C[In response to white's pincer of A, black plans to quickly settle his group in the lower-left corner.]
;W[gq]LB[hp:B][cq:A]C[If white simply responds with A instead, black can live easily with for example B.

White g3 is severe: white plans to make it hard for black to play either A or B.]
;B[gp]LB[gq:A][gr:B]C[Black challenges white A directly.

It would have been more logical for black to play the lower hane of B, keeping to his plan of settling quickly in the lower-left corner. See variation.]

;W[co]LB[jd:A]C[The lower-left corner exchange concludes with black getting territory and sente, but the centre wall that white builds is too strong. From here on, the game favours white.

White c5 is a solid move, but it was also possible for white to play elsewhere, for example at A. See variation.]
(;B[di]C[From here on, the game revolves around how black lives inside the left-side white moyo.]
;W[cg]

Fleeing to the centre with A instead was possible too. See variation.]

;W[ck]
;B[bk]
;W[dk]
;B[ei]
;W[ai]LB[bh:A][bj:B]C[White a11 is a hard-working move, preventing black from building eyes with A while preparing a cut at B.]
;B[hj]LB[hi:B][bj:A]C[Black has no time to connect with A, as white B would have been a severe attack.]
;W[ih]
;B[hm]LB[jj:A]C[This peep may have been an overplay, with the jump of A instead having been safe.]
;W[jj]LB[hn:A]C[White, of course, does not meekly respond with A, but mounts an attack from the centre. Black's situation grows even more difficult.]

;B[ll]LB[hk:A]C[Black could have kept himself connected with A, but presumably he felt that white's getting the hane of m8 would have been too painful. See variation.]

;B[id]
;W[ie]
;B[hd]

;B[oj]
;W[ml]
;B[mm]
;W[lk]LB[nm:A]C[White m9 gives black some hope again, as black A makes a solid shape facing the right side. White should have played hane at A instead and used it to enter the right side.]
;B[nm]C[O7 fixes black's shape locally, and now it is not trivial for white to invade the right side.]
;W[qq]
;B[pr]

;B[ro]LB[ol:A][qp:B]C[Given that black's shape around A is not perfect, s5 is probably too forceful an attack. B instead looked more promising, see variation.]
