(;CA[gb2312]AP[MultiGo:4.4.4]SZ[19]C[The game starts at 8:00. From 11:00 to 11:45 is the lunch break. Each player has three hours plus five times 40-second byo-yomi. The prize for the championship is 300,000,000 Korean Won. The prize for the runner-up is 100,000,000 Korean Won. Live commentaries are made by Lee Jaeung, 7P.] GN[Korea 18th LG Cup Best of 16]DT[2013-06-12]PB[Tuo Jiaxi]BR[3P]PW[Lee Sedol]WR[9P] KM[6.5]RE[B+R]SO[;]MULTIGOGM[0] ;B[pd]C[B1: Hi, everyone. This is Lee Jaeung, 7P. In this round, Tuo Jiaxi, 3P, plays black. ] ;W[dd];B[pq];W[dp];B[qk]C[B5: Tuo Jiaxi chooses the Chinese opening. The original Chinese opening pattern is not as popular as the mini Chinese opening.] ;W[nc];B[pf];W[qc];B[pc];W[pb];B[ob];W[qb];B[oc];W[re]C[W14: Even two to three years ago, white playing at W8 to enter the corner directly was not considered a proper move. Back then, it was common to think W8 is too greedy for territory and makes black strong on the outside. However, now people think it's too slow if not entering the corner here. ] ;B[rf];W[qe];B[qf];W[nb];B[na];W[jd];B[pe]LB[se:a]C[B21: If black plays hane at 'a' to kill black in the upper right corner, it will start a ko fight. However, black doesn't dare to start a ko easily. ] ;W[fq]LB[hc:a]C[W22: The first impression of black's next move is to start a fight with playing at 'a'.] ;B[cf]C[B23: This move of black's is simple and direct. But the pressure he puts on white is limited. ] ;W[fc];B[bd]C[B25: Next white defending the corner at the 3-3 point the corner is simple and clear. But black would feel relaxed as well.] ;W[po]C[W26: Lee Sedol gives up on the upper left corner and invades into the lower right. This sequence is not easy to play. Some of Lee Sedol's sequences are hard to understand sometimes, even for professional players.] ;B[nq]C[B27: This move is played steadily by Tuo Jiaxi. If white gets entangled in the lower right corner, it would be hard for him to take care of the right upper corner. Now the simplest way for white is to defend the upper left corner in sente and then fix the upper right corner.] ;W[op]C[W28: This move is a common sequence to take care of the lower right corner in a fast pace.] ;B[oq];W[qp];B[qq];W[rq];B[rr]C[B33: This sequence of white's suffers a little loss. White's intention is to take the sente in fast pace and then press the black stones in the upper left corner. And he will take care of the lower right corner lightly. ] ;W[qd]C[W34: This move is surprising. Of course this move is very big and it has a nice aji. It is also supportive to the lonely group of white's in the lower right area. However, this move is a little slow. Probably Lee Sedol thinks there is no particularly good sequence that can be played in the upper left corner, he might as well just play some other beneficial move. ] ;B[pm];W[mo]C[W36: It feels like there will be a fierce fight for victory in the midgame or the endgame.] ;B[mp]C[B37: It's a sequence to press white. White has many means to play sabaki. Lee Sedol is having a long consideration. ] ;W[nn]LB[ro:a]C[W38: The reason why Lee Sedol doesn't make the exchange with the tiger at 'a' in the lower right corner is because he is saving the opportunity to start a ko. ] ;B[lo]C[B39: If white doesn't find any good sequence, he will be embarrassed.] ;W[om]C[W40: This move is indeed played at the key spot. W40: White plays three continueous moves in the style of five-stones. Playing sabaki itself is not a problem. My understanding towards Lee Sedol is, comparing with his super strong capability of calculation and fight, he is even better in playing sabaki. Especially his ability in saving big dragons and taking care of a broken game.] ;B[pn]LB[ol:a][qm:b]C[B41: This move is preventing white playing clamp at 'b' when black plays hane at 'a'. ] ;W[ro]LB[sq:a][ol:b][sr:c]C[W42: However, white gains the best opportunity by playing tiger. If black can't play atari at 'a' next, he has to play hane at the head of the group at 'b'. Then white will play hae at 'c'. That will be an easy sabaki for him.] ;B[ol]C[B43: An absolute move. ];W[sr]C[W44: White is pleasant. He doesn't only fix the upper right corner, but also cleanly handles the lower right corner. ] ;B[no]C[B45: This move of black's is very steady. White will make a life even if he plays tenuki in the lower right corner. Generally speaking, white's gain is cute. But black also wins the power in the center. ] ;W[mn]C[W46: White's asking move is making black frustrated. ];B[on]C[B47: This is the strongest move to put pressure on white. ] ;W[ln]C[W48: Now in Lee Sedol's eyes, there is not any other big territory but being busy in invading black in the lower right corner. In the common sense of Go, this move is boring and heavy.] ;B[ko];W[kn]C[W50: White keeps pressing with no doubts. White already has an enclosure in the lower left corner so he thinks the territory that black gains in the lower area is limited. Lee Sedol probably thinks, as long as he control the center, he has a good chance in this game.] ;B[jo]C[B51: But in this situation I personally believe it's easier for black to play. I still think W46 and W48 are heavy. ] ;W[jn];B[io];W[hm]LB[ci:a]C[W54: Good location. I should say, white makes the center become his sphere of influence. Probably Lee Sedol's intention is, he would rather fix himself with strengthening in the center, instead of fix the thin aji in the upper area. Because of this, it's better for black to extend to 'a' in the left, instead of entering the corner. This kind of complicated thinking that Lee Sedol has makes some sense after all.] ;B[cc]C[B55: Very big. Black's meaning is he's not afraid of white claiming territory in the left area. ] ;W[iq]C[W56: This extension that white makes is a bit too far. It has a weakness itself and it might get cut. But white's intention is to fix the center indirectly. Let's have an assessment of the situation: The upper area can't be considered as white's territory but more likely. In the certain territories, he has eleven points in the upper and lower right area, fifteen points in the lower left corner. With potentials and actual power in the center, he has about 35 points. White has ten points in the lower right area, about twenty points in the right area, ten points in the upper left area. Plus komi and sente, we may say the situation is very close.] ;B[kl]LB[lp:a]C[B57: White has made a two-space extension in the lower area. But black is still keeping an eye at the white stones in the center. Black thinks white suffers a great deal of loss by cutting at 'a'. If white plays elsewhere, black will push through. And there will be no chance for white to cut at 'a'.] ;W[ml]LB[lj:a]C[W58: A simple move for black is to jump next. But it doesn't seem to be right enough. Black can make a knight's jump to 'a'. But he's worried that white might cut with playing diagonal. He is not sure about the upcoming chaos.] ;B[cn]LB[lj:a]C[B59: So black made a move at the key point and then played tenuki. However, if white plays in the center with sente, black would suffer a loss. For instance, white can make a knight's jump to 'a'. White is having a long consideration, because the choice of the next move is very important. Because based on the the move of white's, we can tell if B57 playing at the key point was a good move or a bad one. ] ;W[mj]C[W60: White jumps simply. In this case, B57 becomes almost a bad move. ] ;B[cp]C[B61: The compensation that black receives is territory. It is more steady for black to attach like this than to make a knight's jump into the corner. ] ;W[cq];B[ep]LB[eq:a]C[B63: Ha, this move is almost like unplugging a tiger's whiskers, looking for trouble. Next, it's impossible for white to respond at 'a'. If he does, he is giving points away.] ;W[dq];B[do];W[bp]C[W66: Black suffers a little loss in the end. The result is not different to if black plays tiger at 65, instead of 63. It's just a change in order. It feels like black always has concerns about the center. However, the result turns out to be white making a jump to the center smoothly. We may say the situation for white is much more relaxing now.] ;B[go]C[B67: Black is being patient to thicken himself, aiming to attach and cut in the lower area at the same time.] ;W[hp]C[W68: This move is good timing. If black simply connects and allows white to keep playing in the center, it means black has been playig neutral points in the lower left area from the beginning.] ;B[ef]C[B69: Of course black doesn't want to play a neutral point and connect. ] ;W[lb]C[W70: A thick move. White has a foundation for claiming territories in the upper area. Even though black has played in the center and lower left area with conflicting moves, the situation for the two players is still close. ] ;B[hk]C[W71: Good location. But it still feels like black has lost his pace in the center and the lower left area.] ;W[gl];B[jk]C[B73: A thick move, aiming at white's cutting point. ];W[in];B[ho] ;W[gk]C[W76: Natually black connects successfuly. He is pleased now. However, from B57 to B75, black has almost no gain of territory. ] ;B[hi];W[gj]C[W78: Without noticing, black is getting attacked in the center.] ;B[dj]C[B79: The game has started again in the afternoon. The left area is the only place that black can claim as territory. Tuo Jiaxi is the top one in the Chinese ranking system, but still he's only a 3P. Probably it's only three of them, Lee Changho, Lee Sedol and Tuo Jiaxi, becoming top one player when they are 3P. Tuo Jiaxi has had 20 wins in a row in China recently. And he has a great record in League A. It's a pity that he hasn't won any championship in any international tournament.] ;W[fh]C[W80: Good location. It's not easy for black to claim a big territory. ] ;B[gf]C[B81: Black puts some pressure gently, requiring white to fix the upper area. ] ;W[hg]C[W82: Seperating black's stones at this moment indeed is Lee Sedol's style. If black needs to play sabaki in the center, then the jump he made earlier in the upper area would become beneficial to his opponent very likely. In this case, black really wants to keep attacking the upper area. ] ;B[li]LB[ff:a]C[B83: Black makes an exchange in the upper area and then keeps playing in the center. Probably black thinks without the exchange of jumping, it would be annoying if white attaches to 'a'. It's not clear if this move of black's is good or not. But it's painful for white as well. If he doesn't guard the upper area, it's hard to say he's leading in territory.] ;W[oj]C[W84: A multi-functional move. But the main purpose is to attack in the center. It's too slow if black wants to guard the right area. If he wants to play tenuki, there will be some hidden problem. The ideal intention of white is to fix the upper area with sente by attacking black in the center, and meanwhile, stabilize the white stones in the center and invade the left area. ] ;B[mi]C[B85: At this very moment, a tiny mistake can cost tens of points. At this point of view, Tuo Jiaxi is playing well. In the current situation, we can't say white is left behind. But Lee Sedol has to think really hard if he wants to win.] ;W[ok]C[W86: Black is becoming thinner and thinner in the right area. Next, it's obviously safe for black to connect the center and the upper right area. However, the right area is an unavoidable price to pay. ] ;B[nl]C[B87: It's an asking move to break white's eye shape. We can see black hasn't given up the plan for attacking white's big dragon in the center. White can connect next. However, black has fixed himself with sente. If white plays tiger, he can get sente in the right area. But it would annoying if black peeps the tiger. No matter what, white should fix with tiger and get sente. ] ;W[nk];B[nm]C[B89: Black is playing very aggressively, making another asking move. If white connects, black will block with tiger. It is still painful if white allows black to peep the tiger. The situation will be hard for white in the lower right area.] ;W[mm];B[pk];W[nh]C[W92: This is the top one sequence that Lee Sedol plays. The first impression is it's attacking black blindly. It's hard to make such a decision to attack the center first without concerning the territory of forty points in the lower right corner. On the other hand, it's hard for black to choose now. If he kills white in the lower right corner with force, it will be a lot of bad aji left. And black is in danger in the center.] ;B[mg]C[B93: So, black fixes the center first. Next, white should fix the lower right area. In the opening, it seems that black has played very slowly. Since entering the early endgame, black's thick aji has started to work.] ;W[kj]C[W94: This move shows Lee Sedol's style. If black peeps with playing tiger, it will be hard for white to continue attacking black in the center and instead, white will be in danger in the upper area. The left area will be claimed by black. So white has to entangle with black in the center and make a life with sente.] ;B[qr]C[B95: Black is chasing white in the lower right corner.];W[rm]C[W96: The complexity of life or death in the lower right area is more than expected. W96: If black kills with force, it feels he will be in danger. It's better if black strengthens the center with sente.] ;B[qn];W[qi]C[W98: White cuts off the black's way of retreat and gives up his thirty points in the lower right area. ] ;B[rj]C[B99: Black also has his attitude. He captures white in the lower right area. Next, white has to restrain black in the center or in the upper right area. Now the balance of territory is gone. ] ;W[ne]C[W100: It seems in Lee Sedol's eyes, the forty points in the lower right area is not a big deal. He wants to kill the black stones in the center and the upper right corner thoroughly with this move.] ;B[nf]C[B101: If black gives up the center and connects with the upper right area, he doesn't have much gain. So he allows white to try and kill. It feels the odds of this super do-or-die move is not good. White has too many thin places in his shape.] ;W[og]C[W102: No matter what, it feels that killing thoroughly is impossible. White should capture the center and extend the battle line. ] ;B[me]C[B103: This is a good move. ];W[nd]C[W104: White connects with force, meaning he can't tolerate black peeping from all directions. ] ;B[of];W[ri];B[ph]LB[qj:a]C[B107: White is suffering, especially when 'a' is not a sente. If it's sente at 'a', white would have some chance... Now we can only expect Lee Sedol coming up with a brilliant move or Tuo Jiaxi making some mistake. ] ;W[qj]C[W108: This move is not sente... ];B[jh];W[rk];B[rl];W[sj];B[sl]C[B113: The lower right area is taken by black. Fortunately for white, black is not alive completely in the upper right area.] ;W[lj];B[jf]C[ ];W[ji]C[W116: This asking move of playing diagonal is good timing. If black makes a slight mistake, he will lose the center.] ;B[ih]C[B117: Tuo Jiaxi gives up the center simply. From Lee Sedol's point of view, this move is more annoying. Even though the difference of territory is not that big, it is still too hard to catch up.] ;W[lp]C[W118: Because Tuo Jiaxi has this idea of winning the game without causing any fuzz, his tail might get cut. The battle line will be extended. Of course in this situation, black has advantages. He is 10 points thicker.] ;B[np];W[kq]C[W120: White has gained quite a bit of territory in the lower area. ] ;B[lq];W[cl];B[gq];W[gp];B[fp];W[eq];B[jq]C[B127: This is a good tesuji. ];W[hq] LB[jr:a]C[W128: It's good to play atari here. If he plays atari at the second row, it will be sente for black to stand at 'a'. ] ;B[hc]C[B129: Black doesn't fix the lower left area but invades the upper area. If black gets gote in the upper area, his tail might get cut off. ] ;W[he]C[W130: Normally, no one will play this move. Becase when black plays diagonal, it will capture the upper left area. But white's intention is to harrass black in the center and create chaos. ] ;B[kc]C[B131: This move... It means black is taking out his knife. He doesn't want to be entangled anymore but have a quick result. I think it's very difficult for white. ] ;W[jc];B[kb];W[jb]C[W134: If black bridges under, white will lose five stones. He will have to make a compensation as much as he can in the lower left area. But it's not going to be easy. ] ;B[la];W[kd];B[lc]C[B137: If white finishes the endgame normally, he will probably lose with ten points. ] ;W[jr];B[gd];W[ge];B[fd];W[fe]C[W142: It feels that it would be cleaner if black fix the lower left area, instead of capturing the upper left area. Unless white makes a spectacular move, it is very hard for him to win.] ;B[ec];W[mb];B[ld]LB[ma:a][le:b]C[B145: Is it good for black to play like this? In this case, six of white stones will be alive. Black thinks if he connects at 'a', white can extend on the first row in sente and play diagonal at 'b', which is really annoying.] ;W[dg]C[W146: But white also needs to connect in the upper left area. This is painful too. ] ;B[df];W[ed];B[eb];W[ig];B[ka];W[kp];B[dl]C[B153: This is white's last chance. He has to capture in the lower left area. ] ;W[ci];B[ck];W[cm];B[dm];W[bk];B[di];W[dh];B[bn]C[B161: This is a good calm move. White can't kill it. Lee Sedol resigns. Conclusion: The opening has been processed calmly. W38 and W40 are good sequences. Till W44, white is in good pace. Based on the result, W46 is heavy and slow. Because B89 gets sente by playing atari, white shouldn't save this stone. After B57, white playing at 60 in the center is powerful when black plays at 59. Black jumps to 69 in the upper left area is questionable but thick in general. Based on the result, white makes a mistake around 84. He should have kept away from black in the left area. Normally it's better to fix in the upper area. In the actual game after B87, black gains a sequence of playing at 91 to control the lower right area. The situation gets bad for white all of a sudden. Even though W98 is a do-or-die move, white gets captured in the lower area and black makes a life in the upper right area, there is no way for white to reverse the situation. That's all for the comments. Good bye.])
