Edited and translated by GoGameWorld.com.];B[pd]C[In this semi final match, Xie He 7p and Piao Wenyao 5p played a "civil war". As a result, Piao Wenyao gets to kill a big dragon and advances to the final. Strictly speaking, one big dragon across the whole board surprisingly just doesn't have even one eye, the capturing race in this game is very horrifying and enough to be put into history book.];W[dd];B[qp];W[dq];B[do]
;W[op];B[oo];W[no];B[po];W[nn]C[W10: White puts emphasis on influence, nowadays pros rarely play this way.];B[np];W[mp];B[nq];W[mq];B[or];W[nr];B[oq];W[dl]
;B[hp]LB[fo:a]C[B19: For Black to play at 'a' is steady.];W[ep]LB[fq:a]C[W20 is a good move at this situation, normally White will extend at 'a', then Black can connect at 20. Originally Black seeks to turn body around with B19, however White tries to separate Black fiercely with W20, the situation becomes tense right away.];B[eo];W[fo];B[fp];W[fq];B[gp];W[fn];B[cq];W[cr]
;B[cp];W[br];B[em];W[en]C[B31: For Black to fight directly is clearly unreasonable, so Black elects to turn body around by sacrificing.];B[dm];W[dn];B[cn];W[cm];B[cl];W[bm];B[el];W[bn];B[co]
;W[gm];B[dk]C[Through B43, more pros think White's better, in fact I feel Black can also play.];W[bo];B[kp];W[lo]LB[kq:a][jq:b][ko:c]C[W46 is a slow move, although it is not easy to notice. If White plays at 'a', next B 'b' and W 'c', this way White's eye space is better.];B[ko]LB[jn:a]C[B47 is a tight and good move. Normally Black will make knight at 'a', however this way the pressure on White at bottom is inadequate.];W[hl]C[W48: Since White's liberty is tight on the left side, White has to reinforce with one move, W48 is a valuable move.]
;B[km];W[ln]LB[nl:a]C[W50: White can consider to jump lightly at 'a' to reduce pressure from Black.];B[im];W[mk]LB[nk:a][ol:b]C[W52: For White to play at 'a' is better, in the game Black gets to chase White at 'b'.];B[ol];W[kn];B[jn];W[kq];B[jq]
;W[jr];B[lq];W[kr];B[lr];W[mr];B[lp];W[ls]C[From W56 to W64, White destroys Black's eye shape, however White also damages his own eye shape.];B[hr];W[lm];B[kl];W[ok];B[nl];W[kk]C[W68 and W70 are strong moves, both sides start close-contact fight, no one can't afford to play loosely. The following fight is very intense.]

;W[pj];B[oi];W[qj];B[rj];W[li];B[ki];W[lh];B[kj]LB[il:a]C[B91: Black can consider to push at 'a', not allowing White take tenuki.];W[qi]C[W92: White gets to grab the big point with W92.];B[qh]C[B93 is local tesuji.];W[ri]
;B[rh];W[rk];B[ql];W[rl];B[rm];W[qm];B[pm];W[qn];B[rn];W[ph];B[pi];W[sj];B[oh]
;W[pg];B[og];W[pf];B[of];W[rg]C[The sequence from B93 to W112 is inevitable.];B[mg]C[B113 is the vital point, White's big dragon is very heavy. Black takes initiative.];W[nm];B[pn];W[lg];B[mf];W[mh];B[ke]
;W[jg];B[hj];W[hn];B[in];W[il];B[er];W[bp]C[B125 and W126: Black originally just wants to probe White, but White elects to reduce one liberty with W126, the exchange is not to Black's advantage and should be preserved.];B[ii];W[hh];B[gd];W[hf];B[id]C[B129 and B131 are overplay, White gets to play W130 and acts first in the center. Black is always dangerous.]
;W[fj]LB[hi:a][ij:b][gj:c]C[W132 is unreasonable. For White to play at 'a' is the original move, next B 'b' and W 'c'.];B[gk]LB[gi:a]C[B133: Black can directly make diagonal at 'a'.];W[iq];B[ip];W[jp];B[jo];W[fk]LB[hi:a]C[W138: White still should come back and play at 'a'.]
;B[gl];W[fl];B[fm];W[hm];B[fi]C[B143 is severe, Black attacks White's huge dragon tightly, White sinks into a bitter battle.];W[ej];B[ih];W[ig];B[gg];W[gi];B[hg];W[gf];B[fg]
;W[ie];B[di];W[jd];B[je];W[eg]C[W156: White fights very tenaciously.];B[ff]C[However, after Black turns with B157, White is about to collapse.];W[hd];B[ic];W[hc];B[jc];W[ei];B[ge]
;W[he];B[gc];W[hb];B[gb];W[hi];B[kh];W[kg];B[ks]LB[ib:a]C[B169 and B171 are steady moves. In fact, if Black directly kills liberty at 'a', White is very dangerous. Of course, even in the real game, Black is still favorable.];W[lc];B[kd];W[ha];B[eh]

;B[cg];W[ci];B[ee];W[ne];B[od];W[mb];B[nb]LB[ob:a][bg:b]C[However, with B195 Black still should adopt the same clear strategy, not killing and getting into a capturing race. If Black play at 'a' instead, allowing White to make life, then descend at 'b', Black would still win the game.];W[ob];B[mc];W[js];B[ni]LB[eq:a]C[B199: Black still should make life at 'a'. This way White is not favorable in ko fight.]
;W[mi];B[if];W[jf];B[ib];W[ir]C[In the game, it leads to a capturing race, it seems Black has more liberty, but White plays strongly with W204, Black is not as favorable as imagined.];B[fr];W[eq];B[dr];W[bq];B[gq];W[dp];B[ms];W[ns]
;B[hs]LB[ia:a]C[B213 is the last losing move. For Black to play at 'a' is the vital point. This way Black is favorable.];W[ia]C[After White takes W214, together with two good throw-ins at 'a' and 'b', in the end it leads to an all-dominating ko fight, White luckily wins by one more ko threat.]LB[io:a][gr:b];B[ja];W[jb];B[nc];W[io];B[jq];W[jh];B[ji]
