Copyright by gogameworld.com and weiqi.tom.com.];B[pd];W[dd];B[qp]C[On 2/19, the fastest "two knights" in Go area finally meet in 10th Nong Shim Cup, it is really exciting.];W[dp];B[oq]
;W[qj];B[fc];W[cf];B[qh];W[qm];B[jd]LB[hc:a][mc:b][lc:c]C[Gu Li always tries to build a big moyo, like B7 and B11 in the game. However, Ma Xiaochun thinks, this opening is also clearly defective, if Black wants to enclose the top, Black needs to prevent White from invading at 'a' and 'b', Black couldn't take both, with B11 for Black to play at 'c' is better, next with just one move Black can enclose territory at top.];W[qf];B[pl]LB[ql:a][pf:b][qc:c][pc:d][qd:e][qe:f][re:g][pe:h][rf:i][pj:j]C[If White blocks at 'a', through B 'j', it is Black's ideal shape.]
;W[of];B[nd];W[pi]C[Ma Xiaochun thinks, Black's prerequisite of pulling out B9 on the right side is not enough. Locally Black incurs a big loss in the exchange of B9 and W16, the key is how to use this move, if Black has support in the lower right corner, Black can pull out B9.];B[qe];W[rf];B[ql];W[fq];B[jp];W[oo];B[nl]C[Through B23, it forms an exchange.];W[lo];B[lq]
;W[jo];B[ip]C[Through B27, Liu Xing comments, the situation is unclear.];W[qo]LB[nq:a][nr:b][or:c]C[Ma Xiaochun and Liu Xing think, with W28 White should first attach at 'a', if B 'b', White can crosscut at 'c' to make more threads, White is easier to handle. In the game, Lee Sedol is a little nervous.];B[pp];W[po];B[ll];W[ph];B[rj]LB[rk:a][rl:b][ri:c][jm:d]C[B33 is an asking move, if W 'a', then B 'b', W 'c' and B 'd', White's eye shape is not enough. Therefore Lee Sedol backs off in the game.]
;W[ri];B[rk];W[rh];B[jm]C[B37 is a good move to attack the big white dragon. In Lee Sedol's games, he never makes life by making eyes, he either fights for a capturing race or make exchange by sacrificing.];W[nq];B[nr];W[op];B[pq];W[rp];B[rq];W[rn];B[sp];W[io]
;B[ho];W[hn];B[in];W[kp];B[kq];W[hp];B[go];W[hq];B[jq];W[mm]LB[ol:a]C[W56: If White doesn't peep here, White has the tactic of playing wedge at 'a'. Ma Xiaochun thinks, Lee Sedol is "burning his bridge", it seems Lee Sedol is a little over zealous.

Wang Lei: W56 is a crude move.];B[ml];W[hm]C[Shao Weigang comments, Lee Sedol's strength is gigantic, even at this situation, regardless you are taking White or Black, you can't win the game!]
;B[fn];W[gl];B[fl];W[fk];B[el];W[kl];B[km];W[lm];B[mo]C[Wang Lei: W64 is tesuji, but B67 is more brilliant.];W[mp];B[ko]LB[nn:a]C[B69: For Black to play at 'a' is most relentless, Wang Lei comments.]
;W[kn];B[jn]C[Black captures two key white stones and takes initiative.];W[ol];B[ok];W[om];B[nm];W[mn]LB[ko:a][pk:b][on:c][pm:d][no:e]C[Wang Lei (s): if Black takes at 'a', next W 'b', B 'c', W 'd' and B 'e'.];B[lp]
;W[kk]LB[ko:a]C[B77 is difficult to understand. Wang Lei (s) thinks, if Black takes at 'a', White couldn't play W78, now the situation again becomes complicated, Gu Li misses a chance.

Wang Lei: White messes up the situation with W78.];B[mj];W[pk];B[kj]C[Wang Lei: B81 is the vital point.];W[jj];B[ki];W[ji];B[ko];W[oj];B[nk];W[pm]
;B[jh];W[ih];B[no]C[Black fixes his shape, later on taking two stones is also sente. However, Gu Li always plays "capturing-stone game" here, Liu Xing shows concern. Wang Lei thinks, White is leading in territory, the situation is still about even.];W[nn];B[ln];W[on];B[jk];W[cp];B[ek];W[ig]C[Both Wang Lei and Peng Quan feel, with B97 Black should play at 98, the potential at top is bigger than the left side.];B[ik];W[kh]
;B[fe];W[db];B[ke]LB[ld:a]C[B103: For Black to reinforce at 'a' is more simple and clear.];W[hc]C[Hu Yaoyu and Liu Xing analyze, White has 17 points in the lower left corner and 25 points on the right side, Black has 60 points at bottom excluding W60 and four white "dead stones", i.e. at the lower half of the board they almost have same territory. In terms of shape, Black is better.];B[hd];W[kc]C[W106: White initiates a fight, Lee Sedol must first make something happen here before Gu LI builds thickness.];B[ro];W[rm];B[jc];W[jb];B[ib]
;W[oc];B[od];W[lb];B[mc];W[hb];B[ic];W[ld];B[lh]LB[ja:a]C[Wang Lei: B119 is inexplicable, if B 'a', White will sink into a bitter battle.];W[ia];B[kg]LB[gb:a]C[B121 appears a casual move, Black should attack White at 'a', Wang Lei feels, Black can seal off White at any time. Only if Black doesn't die in the center, it is difficult for Black to lose the game. In retrospect, after Gu Li takes the key stones of W24 and W46, Lee Sedol's "flying knife" basically couldn't be thrown.]
;W[gd];B[gc];W[he];B[id];W[me];B[gb];W[lf];B[pc];W[rd];B[re]LB[rc:a]C[B131: For Black to play at 'a' is the original move.];W[rb];B[pf]
;W[og];B[qg];W[rg];B[qb];W[se]LB[qa:a]C[W138: If White plays at 'a', this hane is very fatal, Black has to ko-live. However Lee Sedol seems to overlook it.];B[ob];W[ge];B[fd]LB[ha:a]C[B141: For Black to take at 'a' is the original move.];W[ha];B[de]
;W[ce];B[kf];W[fg];B[cc]C[Wang Lei: B143 and B147 are also meaningless.];W[dc];B[mf];W[ne];B[gf];W[hf];B[gg];W[kd];B[je];W[gh]
;B[ff]LB[if:a]C[Again Lee Sedol fails to deliver the fatal tactic in the capturing race. With W156 if White directly plays at 157, B156, White can play the clever move at 'a', Gu Li can concede the game.];W[fh]C[However, from B121 Gu Li appears favorable, so far the situation becomes unclear. We can see Lee Sedol really can "mess up" and you can't kill him.];B[hg];W[gj];B[le];W[md];B[ga]C[Through B163, the second "close contact" fight comes to an end, Gu Li makes life. Wang Lei analyzes, the situation is about even now, it is perhaps half-point game.];W[dg];B[cb];W[ja]LB[da:a]C[Wang Lei: If W 'a', there is no loop hole in the corner.]
;B[cd];W[da];B[be];W[bf];B[ad];W[ee];B[ef];W[df];B[hj];W[hi];B[ii];W[hh];B[if]
;W[dj]C[W180 is a clam move, Lee Sedol allows Black to live the corner.];B[ej];W[di];B[af]C[B183: Black fights like hell, Gu Li must feel his territory is not enough, however Black has no enough ko threats. Earlier Black plays the ko threats in the lower right corner as endgame, moreover the ko threats of B149 and B161 are also played out as "forcing moves" (under time pressure), now Black wants to fight the ko, in theory, Gu Li is not looking good.

Wang Lei: Black fights too strongly, Black should reinforce at 'a'.]LB[ab:a];W[ca]C[Wang Lei: Following W184 White plays very steadily, Gu Li tries all he can but couldn't turn the game around.];B[ba];W[bb];B[ab];W[aa];B[qk];W[pj]

;B[en];W[nb];B[nc];W[bh];B[ai];W[dn];B[rc];W[sc];B[qd];W[qc]C[Now both sides have same territory on the board, i.e. Gu Li (Black) must squeeze one "Komi" somewhere, Black is still not good.];B[kb];W[ka];B[rc]
;W[em];B[fm];W[qc]C[Black has 48 points in the lower right corner, total 57 points, White has 57+ points on the board, if no surprise, Gu Li will "fall".];B[eo];W[ep];B[rc];W[hk];B[ij];W[qc]C[Wang Runan thinks, Gu Li fights very strongly, the key is, with B97 Black failed to play double hane.];B[do];W[co];B[rc]
