;B[pe];W[ec];B[pp];W[dp];B[kd]TR[oc]C[GP\: I've played this recently as it prevents White from approaching at the triangled point and making a semi-comfortable 2 point jump extension. The idea is to build a more powerful framework from this position, and prepare the approach at C16. Is this viable?

HH\: I think there is very little wrong with it. After this move, White is no longer in any hurry to invade the upper right corner, because for Black Q7 is now less attractive, as it makes L16 a bit overconcentrated.]
(;W[qn]C[GP\: Wrong side? It feels like White is getting a bit greedy here perhaps. I prefer the variation

HH\: Nothing wrong with playing on the right, but I think the wedge at R9 or R10 is better. This move allows black to pincer, which works well with his stones in the upper right. ]
;B[ql];W[nq];B[np];W[qp];B[oq];W[qq];B[mq]C[GP\: I'm happy enough with this trade, as White cannot easily develop the lower edge.]
;W[qc];B[oc];W[re];B[qf]C[GP\: Playing for influence and sente.];W[rf];B[cd];W[cg]
C[GP\: Ooh, interesting!];B[de];W[hc];B[dc];W[ed];B[db];W[ie];B[jf]C[GP\: The right direction and urgency to be consistent with my top right? Or was F3 bigger? Or the pincer on the left?

HH\: I would prefer to tenuki. F3 would be my move]
;W[pm];B[pl];W[qh]
(;B[ro]C[Mistake. This loses points without compensation. Black can try S6 here. See variations]
;W[rn];B[po];W[qo]C[Now it is clear the S5-S6 exchange was a pure loss.];B[om];W[ol]
;B[pj];W[nl];B[nj]C[S11 for shape (in sente) first];W[qj]C[Painful];B[pi];W[qi]
;B[pn];W[qm];B[pk];W[nm];B[qg]C[Black should defend P7, the R13-S13 exchange gains nothing]
;W[rg];B[ph]C[GP\: Not that happy with this trade in hindsight, but it's either sente or I may get to attack O8.

HH\: Black must defend P7. Only move.]
;W[kb]C[White should capture P7. It is huge, nothing else comes close.];B[if]C[Not urgent, white can ignore this, especially after L18.]
;W[he];B[lk]C[GP\: 2nd line feels slow, so I ignore L18 for bigger ideas. Playing this as a dual purpose to expand the framework and to hopefully get the chance to connect at P6.

HH\: Ignoring L18 is good, it is a pure gote stabilizing move, nothing more, but this is no good. You're not expanding your framework, your turning influence into territory. Black is very strong here, so this is much too close and is overconcentrated. P6 would be the right way to build a large framework, with a free dead chain and/or weak group in it too \:)

HH\: I will shut up about P6 for now, but it will remain the largest move on the board for quite some time \:)]
;W[fq];B[dj]C[GP\: Pincer with the chance to now approach the corner as well.];W[iq]
C[GP\: Should be E13?

HH\: Something around there anyway. White is trying to limit black's influence, but P6 would be much better for that ;)]
;B[cn];W[fg]
(;B[dg]C[Better at E13, see variation.];W[dh];B[eg];W[eh];B[fh];W[fi];B[gh]C[GP\: I decided here that I could either get a big left or trade for some serious central influence.]
;W[gi];B[ei];W[di];B[ej];W[hh];B[gg];W[ff];B[hg]C[GP\: I want my moyo!

HH\: The right choice \:)]
;W[cf]C[HH\: Mistake. White should capture at D14 immediately];B[cj]C[Also a mistake, should be E15.]
;W[df];B[hl]C[GP\: Now Black feels ahead. P6 is now huge.

HH\: P6? Huge? ;)]
;W[eb];B[be];W[on]C[GP\: Grrrr!

HH\: Huge \:)];B[lm]C[Too small, C3 is huge.]
;W[dm]C[GP\: White decides that Black is getting too much, but Black must resist this.
]
;B[dn];W[em];B[en]C[GP\: I'm hoping the lower left will get too thin to cope here, but Black must be careful.]
;W[fm];B[cm]TR[dj][dn]C[GP\: I didn't see any option other than this. Both marked groups benefit a lot from the connection. "Get strong before attacking"]
;W[fk]C[GP\: Really? Wow, White is worried about Black having too many points. This feels greedy again - better to F6 first? or H7 maybe?]
(;B[gl]C[GP\: Preventing the contact tesuji at H7, and threatening to cut. In hindsight, maybe G5 was better?

HH\: Yes, I would prefer G5]
;W[fn]C[GP\: I realised now that the F8 cut doesn't really work - whoops!]
(;B[fo];W[go];B[ep];W[eq];B[gn];W[fp];B[eo];W[gm];B[hn];W[hm]C[GP\: J7 doesn't quite work yet. Maybe J6 is better, but those two stones will die, and then what? Two eyes should be achievable for White.]
(;B[dq]C[GP\: Now if White plays C3 Black can make good profit. Preparing a couple of viable options.]
(;W[il]C[GP\: White opts to trade.];B[dr]C[GP\: The profit here is good enough for Black, but maybe the kill was possible enough that this was soft. Either way, Black is happy with the profit.]
;W[in];B[gp];W[gq];B[ho];W[io];B[ji]C[GP\: And sente to recover some of the moyo.]
;W[cp];B[bq];W[bp];B[cq];W[er];B[bo];W[nr];B[or];W[mr];B[lq];W[lo]C[WHite should continue saving the O3 stones]
;B[lr];W[jr];B[qr];W[rr];B[qs];W[pq]C[Better at S1];B[pr];W[ld]C[GP\: The game stakes go up. White tries hard to recover the deficit.]
;B[jc]C[GP\: Threatening some fun aji against the top. This is a risky play by Black but Black cannot afford to be passive. P16 causing concern.]
;W[md];B[jb]C[GP\: Separating, and hoping to attack the top left White group.];W[mf]
C[GP\: Threatening the push and cut at K15];B[ee];W[ef];B[fe];W[gf];B[gd];W[ic]
;B[ke]C[GP\: Now I mistakenly thought the top left group was dead with sente, but White has miai for two eyes \:(]
;W[od]C[GP\: So White attacks. Black is in trouble again...];B[bh]C[GP\: Forcing with profit first]
;W[ib];B[pd];W[pc];B[nd];W[oe];B[ne];W[of];B[mc];W[ob];B[nc]
(;W[lc]C[GP\: This surprised me slightly. I felt O14 was significantly better.

HH\: It is]
;B[nf];W[mb];B[ja]C[GP\: Threatening G18.]
(;W[gb];B[nb];W[na];B[ng];W[lf];B[lh];W[bb];B[bc];W[cb];B[cc];W[da];B[ab];W[ea]
;B[bg];W[ih];B[pb]C[GP\: A probe, but it seems foolish. Black I think should have lost the game here perhaps...]
(;W[oa];B[kf]C[GP\: The idea being. Q18 now sets up a squeeze if White tries to cut (see var).]
(;W[qd];B[og];W[hj]C[GP\: Better at J9?

HH\: I'd prefer J10];B[ik];W[jl]C[White should cut]
;B[ii];W[hi];B[hk];W[fj];B[lg]C[GP\: Now Black fixes the cut aji and sets up the squeeze at the same time. Black is now comfortably ahead (10-15 points)]
;W[jk];B[ma];W[la];B[pa];W[ma];B[ka];W[lb];B[le];W[qb];B[me];W[qa];B[ij]C[GP\: Capturing in sente, and connecting all Black stones]
