;W[cp];B[dq];W[ep]LB[eq:a]C[White16 is to get the sente, if White moves at point 'a', White may get the gote.];B[fr];W[ej];B[bk]LB[eh:a][gi:b]C[If Black19 moves at point 'a', then White moves on at point 'b', good pacing.];W[bj]LB[bl:a]C[White20 is the counter-back. If White moves at point 'a', Black will move at White20 and get sente.]
;B[cj];W[bi];B[bh];W[bl];B[dk];W[cl];B[dj];W[ei]C[This is "One way street". Seems Yu Ch'ang-hyeok is not affected by his loss in the first round.];B[fe];W[bf]LB[bg:a][dh:b]C[White30 is a good move to defend by attacking. Black consumed much time for Step31. Point 'a' or 'b'? Quite difficult to make the choice.]
;B[bg];W[be];B[dh]C[Must.];W[fg];B[ff];W[hg];B[he];W[hc];B[je];W[jg]C[Till Step40, seems the rhyme of White is quite good, Black somewhat disturbed. But considering this is a fight in White's area, a little leading by White is reasonable.];B[gj]C[Black41 want to attack White as a big whole group.];W[ij]C[White42 is a good, slight move.]
;B[ek];W[qf]LB[qj:a]C[Considering the defending direction of the lower-right corner of Black, White44 did not choose point 'a'.];B[pi]C[Of course.];W[of]LB[qc:a]TR[hc]C[Since there's the White stone with the triangle mark, White46 is better than point 'a'.];B[rd]TR[hc]C[Also considering the White stone marked with triangle, Black moves flexibly at Step47.];W[nd];B[ih]
;W[ig];B[gh];W[hh];B[hi];W[ii];B[gg]C[Till Step55, Black choose to get cash of 15 moku in the middle with the price of sente.];W[nb]TR[pi]C[White56 forced Black to make the corner alive. White took the initiative.];B[pb];W[re];B[qc]C[Lunch break.];W[pk]C[Of course.]
;B[pg];W[pe];B[mh];W[od]C[After White64, the upper-right corner is not unconditionally alive.];B[kh];W[jh];B[kj];W[kf];B[qm]C[Black65 to 69 rush to attack, hoping to take the initiative.];W[mj]LB[oh:a]C[White70 is preparing for cutting-in by point 'a'.];B[nk]C[Black71 is also "defending by attacking", and it's the critical point of shape.]
;W[ri]C[White72 is testing Black's reaction.];B[rb]C[Black73 thought now it's the time to make the group totally alive.];W[mk]LB[oj:a][nj:b][oi:c][ni:d][oh:e]C[Fierce attacking.

;W[mm];B[nm];W[mo]C[White78, 80 chose a safe strategy. Obviously White don't think Black is the one that leads.];B[mq]LB[fq:a]C[Black81 took the cash and preparing for cutting at point 'a'.];W[fq];B[gr]C[Black83 tried to get the sente.];W[bq]C[Good timing for White84.];B[br];W[er];B[bp]
;W[bo];B[aq];W[dr];B[cr];W[hr]C[From Black85 till White92 there's the exchange. White gained at cash but lost the sente.];B[rj]LB[oh:a]C[Black93 was very big. Now Black gained more at cash, but White gained more in thickness. It was still not sure who is leading. White began to consume time thinking, maybe it is calculating whether it is ok to move at point 'a'.];W[qj]LB[rk:a][qi:b]C[White94 is the shoobute, testing Black's nerve: point 'a' or 'b'?];B[kp]C[Black95 is astonishing, this move is very risky.]
;W[rk]TR[mj][mk][ml][mm][mo]C[White96 eat the black stone totally. Here Black lost quite a lot. If Black cannot efficiently attack the group of white in the middle, with triangle marks, Black will lose.];B[ic]C[Black97 is quite big, but seems not continous.];W[nn];B[mi]C[The exchange of White98 to Black99 is reconsiderable. Seems not good to White.];W[kk]LB[jk:a][jj:b][kl:c]C[After White100, Black still have the trick of point 'a', if then White moves at point 'b', Black can move at point 'c'.]
;B[rh]LB[om:a][mc:b]C[Fierce attacking of Black101.

;B[db];W[ga];B[ca];W[fa]C[Till Step160 the result is a yose-ko (appoarch-move-ko). In fact it is a double-appoarch-move-ko. It is not a burden to White.];B[ib];W[eb];B[lr];W[ns];B[fb];W[lc];B[ke];W[lf];B[iq]
