A pincer stone might strengthen C6 as well so I would likely do that] (;B[dg]LB[oc:C][ee:A][dj:B]C[Either one space jump or counter pincer, tenuki seems to give black too much in the upper right] (;W[fq]LB[od:B][de:A][qn:C]C[Not a move I had guessed, but even after D15, C15 still has aji and the left side is very open A is my first instinct here is A, but B and C are tempting as well, F3 doesn't feel at all sente against C6 so I would definitely tenuki] ;B[de]LB[jc:B][oc:A][pj:C]C[The top side seems important but the right is much more open, Likely I would approach at A] ;W[od]LB[oc:C][ld:A][qn:B]C[I would almost certaily pincer, likely at A as any black counter pincer will hopefuly have a problem with the black wall Tenuki is also fine (at B for example) but I don't see anything else particularly pressing I want to do. C lets white settle quickly and easily next to black's wall, good territory for black but it seems very passive] ;B[oc] ;W[nc] ;B[pc] ;W[nd] ;B[qf] (;W[jd]LB[cd:B][hd:C][dj:A]C[Clearly my intuition was wrong! Black seems to be playing for territory and isn't to fussed about the wall. A move at C later might make a nice double-wing type thing The right side is fairly boring after R14, moves at A to reinforce the left side or B to kill the aji in the white stone look better to me] ;B[cd]LB[gc:B][dk:A][qn:C]C[Black's left side is in danger of getting quite large with another move, I would be looking to pincer the bottom left stone to avoid this B is also very big and helps settle the white group but seems kind of endgamey to me. Again a move at C is big but fairly passive] ;W[ck]LB[en:A][qn:D][cp:B][cq:C]C[One point jump is the obvious move but seems to let white have everything white wants Given black is playing for territory I would expect a move at B or C to try and take the corner ] (;B[bp]LB[ek:D][dn:B][cq:A][iq:C]C[Not really convinced by this move, it doesn't take the corner and doesn't get into the centre. The only thing can imagine is that black expects to get out and is squeezing white's eyespace for an attack on the D4 group at a later date, this seems like alot to hope for A seems most obvious for white but attempting to take the outside with B might work too ( although this might end up sacrificing C9 which probably isn't ideal right now. C is overly passive I think. Jumping with D might be the right idea but seems quite slow] ;W[cq]LB[dl:B][en:A]C[Surely A or possibly B? if this is the case why did black make the exchange instead of just jumping? Isn't this conventionally considered very bad?] ;B[do]LB[gc:C][ci:A][qn:D][jp:B]C[wat. Not a move I've seen before... but I can't really see a good white response, perhaps this is a case where tenuki is punishment enough? As such I'd be looking at any of A-D or moves in those areas, probably A as a first bet given this stone is likely to become weak fairly soon] (;W[cp]C[I'm also not at all convinced by this move, as with the variations I looked at it seems like black will settle and possibly with territory, I can't see what white;s aim is here. I still think white shoudl tenuki] ;B[bq] ;W[co] ;B[bo] ;W[dn] ;B[dm] ;W[eo] ;B[cm]LB[gc:C][ci:A][em:B]C[As I thought black has settled with territory, C9 now looks terribly weak and while white has sente black must be ahead terrotorially As such a move at A or thereabouts is urgent, I don't think white can afford B, and C, while big, isn't exactly sente] ;W[dh]C[expected] ;B[cg]LB[gc:A][mp:B]C[after the D12/C13 exchange white might be abe to get away with tenuki. Given white is behind on points I think playing another move here is difficult to justify I like A but extending from the strength on the bottom side is big too] ;W[nq] ;B[hc]C[O3 and H17 seem to have been miai As white I would have liked the top side more given it feels more of a reverse sente move than the pure gote of O3] ;W[ic] ;B[hd]LB[jf:C][em:B][qo:A]C[A and B are both very large, I'm not sure how urgent a move at C is though I would worry that the white group on the top side is too weak to leave] ;W[pd]C[obviously trying to strengthen the top group but seems ajikeshi, perhaps the right side is boring enough that endgame around R13 isn't that good?] ;B[qc] ;W[hb]C[still dealing with that top group] ;B[gb] (;W[ch]LB[bh:A][eh:B][mp:C]C[Clearly the top group is now defentable enough to tenuki at C12 C12 seems heavy to me I would feel happier playing around F12 instead, trying to make a light but floating group I would expect a hane at A or B from black immediately, probably A given the territorial style again.] ;B[bh] ;W[bi] ;B[bg]LB[gh:A][fk:B]C[Now I would imagine moves around A or B to make shape for the white group] ;W[fl]LB[fm:A]C[trying to build and connect/make shape at the same time, but it also looks quite thin... I would try and cut at F7] ;B[mp]LB[mn:A][kp:B]C[A move I considered but differently timed, the left side feels more urgent. Perhaps this can be considered a probe? If white connects the left groups black can easily reduce the moyo after N4, but if white responds then black can cut at F7 and hope to reduce the white moyo while attacking the C12 group Given connecting on the left and responding to N4 allow black to decide easily what to do, maybe white will counter attck N4 at somewhere like A or B] ;W[kq]LB[fm:A]C[nearly right! Now black should cut at F7] ;B[fm]LB[el:B][em:C][gm:A]C[white could try and save the left group or build in the centre] ;W[gm]C[Looks like white will sacrifice the left group...] ;B[el] ;W[fn] ;B[em] ;W[gl] ;B[dj] ;W[mn]C[Black needs anothe rmove to guaruntee the points on the left side, so white will likely get to play the big point on the right Then black will have to reduce the white moyo in teh centre, I don't think these are difficult concepts for me to understand but following through with them is a different matter] ;B[fj]LB[pj:B][qj:A][pk:C][qk:D] ;W[pm]LB[il:A][jl:B][kl:C][im:D][jm:E][km:F] ;B[jm]C[White will likely counter attack and a fight will develop] ;W[kl]C[I'll stop reviewing here for now as I wanted to look mostly at the opening and early middle game, however I'll return to this one another time as the follwoing middle game fighting is very interesting] ;B[il] ;W[gj] ;B[kn] ;W[fi] ;B[kp] ;W[jp] ;B[jo] ;W[lp] ;B[lo] ;W[ko] ;B[hn] ;W[kp] ;B[ln] ;W[gn] ;B[mm] ;W[mo] ;B[ll] ;W[eh] ;B[qp] ;W[qo] ;B[po] ;W[oo] ;B[pn] ;W[on] ;B[qn] ;W[qm] ;B[rn] ;W[qq] ;B[rp] ;W[pq] ;B[rm] ;W[qk] ;B[io] ;W[rl] ;B[rq] ;W[rr] ;B[sr] ;W[rs] ;B[sm] ;W[kj] ;B[lk] ;W[cj] ;B[ib] ;W[jb] ;B[ha] ;W[br] ;B[bl] ;W[mi] ;B[ip] ;W[aq] ;B[bk] ;W[pg] ;B[kr] ;W[jr] ;B[lq] ;W[jq] ;B[ir] ;W[lr] ;B[qg] ;W[if] ;B[ph] ;W[oh] ;B[og] ;W[pf] ;B[oi] ;W[nh] ;B[pi] ;W[ri] ;B[ni] ;W[mj] ;B[ng] ;W[mh] ;B[pe] ;W[of] ;B[oe] ;W[nf] ;B[ne] ;W[mg] ;B[me] ;W[jl] ;B[km] ;W[mq] ;B[nl] ;W[ok] ;B[iq] ;W[gr] ;B[kk] ;W[jk] ;B[jj] ;W[ik] ;B[hk] ;W[ij] ;B[hj] ;W[ii] ;B[hl] ;W[ej] ;B[hi] ;W[ld] ;B[rh] ;W[qi] ;B[qh] ;W[ff] ;B[hg] ;W[ee] ;B[ef] ;W[ed] ;B[fe] ;W[dd] ;B[cc] ;W[fg] ;B[df] ;W[ge] ;B[fd] ;W[ih] ;B[om] ;W[ol] ;B[nm] ;W[ar] ;B[bj] ;W[ai] ;B[am] ;W[le] ;B[ob] ;W[nb] ;B[ie] ;W[nn] ;B[ig] ;W[hf] ;B[je] ;W[hh] ;B[jg] ;W[gh] ;B[jf] ;W[hm] ;B[im] ;W[ho] ;B[in] ;W[mk] ;B[nk] ;W[sl] ;B[fk] ;W[gk] ;B[nj] ;W[kb] ;B[ek] ;W[gd] ;B[fc] ;W[md] ;B[gp] ;W[go] ;B[gi] ;W[jh] ;B[en] ;W[fp] ;B[hp] ;W[fo] ;B[ei] ;W[fh] ;B[lj] ;W[ki] ;B[kg] ;W[kh] ;B[id] ;W[jc] ;B[ke] ;W[na] ;B[kd] ;W[kc] ;B[lb] ;W[lc] ;B[ja] ;W[ka] ;B[lf] ;W[mf] ;B[qe] ;W[ia] ;B[mb] ;W[hb] ;B[li] ;W[gc] ;B[ib] ;W[fb] ;B[ec] ;W[hb] ;B[lh] ;W[lg] ;B[ib] ;W[ml] ;B[lm]) (;W[fh]C[more sabaki than C12?])) (;W[eo]C[Most of these sequences let black settle with thickness, possibly even with sente, the hane may not be good for white] ;B[en] (;W[fn] ;B[ep] ;W[fo] (;B[cp] ;W[dq] ;B[em]) (;B[bq] ;W[co] ;B[dn] ;W[cp] ;B[bo] ;W[cr] ;B[el])) (;W[fo] ;B[bq] ;W[br] ;B[cp] ;W[dr] ;B[fn] ;W[go])) (;W[fo]C[Ultimately this seems to let black off the hook too much] ;B[el] (;W[ci] ;B[cl]) (;W[dm] ;B[cm] ;W[dl] ;B[en] ;W[em] ;B[fn] ;W[go] ;B[fm] ;W[fl] (;B[ek] ;W[gl] ;B[cj]) (;B[gl] ;W[fk] ;B[hm])))) (;B[en] ;W[ek]C[white successfully disrupted any black potential on the left for very little effort]) (;B[qn] ;W[co] ;B[dn] ;W[ek] ;B[gn] ;W[gp] ;B[hl] ;W[ei]C[possible])) (;W[jc])) (;W[dj] ;B[de] ;W[co] ;B[dn] ;W[fp] ;B[dl] ;W[cg] ;B[ch] ;W[dh]C[A possibility for the counter pincer?
