He won the Mingren (Chinese Meijin) title, defeating Gu Li and Kong Jie in 2010 and 2011 respectively. That was very sensational in China, because Gu Li and Kong Jie are two of the best players in the world.];W[dq]C[Jiang is currently ranked number 4 in China. He's very good at fighting like Gu Li, and very good at endgame like Kong Jie. :)];B[oq]C[This is Lee Changho's 10th final match in a row where he's been the runner up. :(];W[qj]LB[qf:A][qj:B]C[This splitting play is rarely played in pros' games recently. A is far more popular. I've talked about the local differences between A and B in previous commentaries. For example in this game:http://gogameguru.com/commentary-sedol-lee-changho-lee-prices-information-cup/and this one: http://gogameguru.com/commentary-hane-naoki-yamashita-keigo-66th-honinbo/ though the opening was slightly different.];B[co]C[Lee Changho is still the most popular player in Korea, even if he's not perfect anymore. It's because Baduk fans admire and respect Lee for his attitude and spirit towards Go.];W[dl]LB[co:A]C[One of the most popular pincers against A. ];B[ep]LB[cj:F][dn:A][fo:B][gp:D][fq:C][gq:E]C[For this black move, the variations are relatively simple. In addition to this pressing move, A to F are all possible.](;W[dp];B[do];W[eo]C[This is right for white. ];B[dm]C[Tesuji. ](;W[fo]C[Right move. ](;B[el]C[This is also possible. ](;W[dk];B[en];W[gq]C[Jiang wouldn't care whether the variation was complicated or not as he's young! ];B[ek];W[di];B[dj]LB[fc:B][bl:A]C[B could also play at A here. Then white would play at B next. ];W[cj];B[ej];W[ci];B[fc]LB[dj:B][bl:A]C[Speedy. Jiang might have thought this was better than playing at A instead of B. ];W[df]LB[dc:A]C[A is also possible for white, but Lee's play in this game is quite solid. ];B[qh]C[Right direction. The upper side is more important than lower side in this position. ](;W[qo]LB[qm:A]C[This is a kind of a modern joseki. A is more common. ];B[qm]C[This variation could be pretty new to your eyes, because it's a kind of new joseki.  ];W[pp];B[pq];W[qn];B[rp]LB[pm:A][qq:B]C[Inevitable. If black extends at A, white would cut at B and capture black's single stone. ];W[pm]C[The game's still even and black has sente again. ];B[jd]LB[qh:A]C[A good place. Black has been planning to play here since A.];W[qf]LB[nc:A][pc:B][qc:C]C[There are several other options for white too. A to C for example.](;B[qd]C[This move is unusual in this situation. It looks as if Jiang wants to fight here as the game's been too simple so far.];W[mc]C[This move looks ambiguous. ];B[kc]LB[jb:B][oc:A]C[Right direction. If black answers at A, white would slide at B. ];W[oc]C[Good exchange before running away. ];B[pc];W[me]LB[oc:A][pc:B][nd:C]C[If white didn't exchange A for  B, black would peep at C to make white heavy. ];B[pf];W[pg]C[Good move. ](;B[of]C[Right move. ];W[qg];B[nd];W[md];B[ng];W[ke]LB[lf:A]C[A nice jump.

When there's some bad aji in your area, you'd better play safely. ];B[ql];W[rl];B[qi]C[A bad aji still remains.](;W[rj]C[Right answer. ];B[oh];W[rh]C[White survives, but right side becomes too thin.

You can't get a good result with a bad shape. ];W[bd]C[Big endgame. The game's slightly better for white now.];B[qe];W[re];B[nf]C[Black tries to go all out against white's top group.

However, white made a mistake, and the game suddenly ended. A was simply a losing move, and B is the finishing blow.Jiang Weijie showed his outstanding sense in the center, and he didn't miss the chance to finish the game. On the otherhand, Lee Changho managed the game very well, and he caught up with C and D, but in the end, he missed the exchange of a move at E before playing A, and it cost him the game. After this game, Jiang won the second game as well, and won the 16th LG Cup. He made a new record as the youngest player to win the LG Cup.He was also promoted directly to 9p from 5p, as a special case for winning an international title.
