W: Tang Weixing 3P
B: Lee Sedol 9P
Commentary by Michael Redmond
Edited by Chris Garlock

After a very calm start for both players, Lee Sedol starts to attack in the middle game, sparking a very exciting fight, where I've concentrated most of my comments. Tang ably parries Lee's attack and after the dust settles it's a very close game. ]

C[This is a slow, calm opening that tends to lead to a close game. ];W[oq]
C[Approaching the 3-4 pt is the biggest opening point...];B[po]
C[...but since White has a low and solid shape in the lower left corner White can now switch to the right side. ]
;W[qi];B[qk];W[qf];B[qe];W[pf];B[nc]
C[White now has a choice: he can play on the lower side to gain in territory, or reinforce the right side group to prepare for an invasion into Black's upper right corner. ]
;W[oj]
C[White chooses to strengthen the right side group. ];B[np];W[mq];B[re]LB[qc:A]
C[Black prevents a White invasion at A, looking to attack the right side White group later. ]
;W[mp]
C[Black's next move is very important.  White has a developing moyo on the lower side. How should Black play to reduce that?]
;B[go]
C[This move is reduces White's lower side, and also expands Black's potential in the center, a double purpose move. ]
;W[hp]LB[ge:A]
C[If I were Black, I think I would switch to A  for a center moyo. ];B[in]
LB[ge:A][jp:B]
C[This move makes miai of A and B. ];W[gf]
C[Black's potential in the center is mostly gone now, but in return he has the potential invasion at B, which I would play immediately. ]
;B[jd]LB[jp:A][lc:B][gd:C]
C[Although I would have played at A, this extension is also a very large move, preventing a White extension at B, and threatening to cut White at C. ]
;W[ne];B[jg];W[gh]LB[gd:A]
C[Black can cut White off with a move at A, but White does not want to protect directly. This jump strengthens White in the center while erasing Black's potential for territory. ]
;B[gd];W[fd];B[dd];W[cc];B[fe];W[ge];B[gc];W[gb];B[hb];W[fb];B[ic];W[ld]
LB[jg:A]
C[Instead of directly protecting the denter group, White counter-attacks. This move threatens to erase Black's upper side while also aiming to cut off the Black stone at A. ]
;B[nd];W[me];B[lc];W[jf];B[if];W[ie]LB[je:A][kf:B][ih:C]
C[Cutting at Black A, White B, Black C is the strongest way to play, but cutting at A is bad shape. In the game we will see Black playing the good style move. ]
;B[kf];W[je];B[ke];W[hd]LB[hc:A][kd:B]
C[Black can't connect at A, as White will then cut at B.];B[kd];W[hc]
C[I think this was an even trade. Black's attack in the center failed, but in return he now has a solid territory on the upper side and a potential attack on White's right side group. ]
;B[oh]
C[This is a vital point to take away White's eyeshape. ];W[pk]
C[White tries to make good shape. The var for Black's next move shows what I would expect. ]
(;B[qh]
C[This attack starts a difficult fight. ];W[rh];B[pi];W[qj];B[pj]LB[ph:A]
C[Throwing in at A is the tesuji for White now (see variations). ]
(;W[ql]LB[ph:A]
C[White changes the order of moves, saving the tesuji at A for later. ];B[rk]
;W[ph];B[pg];W[rj]LB[rg:A][qg:B]
C[If Black A, White plans to cut at B and play the ko. ];B[sj];W[ri];B[pl]
;W[ok];B[rl];W[oi]
C[Black can't connect, see var.]
(;B[nh];W[ph];B[pi];W[qm];B[rm];W[pm];B[qn];W[lg]
C[White cuts Black off to counter-attack. ];B[rf];W[mi];B[rg]LB[ph:A]
C[Since Black A is forcing, Black is now connected. ];W[kg]LB[mh:A]
C[So far, Black's attack has not been successful, as White has gained in the center. Black will now try to profit from the cut at A. ]

;B[gp];W[gq];B[ip];W[ho];B[hn];W[hq];B[kn];W[kj]
C[Now White is connected in the center. ];B[jo];W[no];B[mn];W[op];B[kq];W[qr]
;B[rr];W[qq];B[rq];W[rp];B[pr];W[pq];B[ro];W[bh]LB[bg:A][dh:B]
C[This is the tesuji to reduce Black's left side. If Black A, White B will make trouble for Black. ]
;B[ci];W[of];B[qg];W[bf];B[gi];W[ij]
C[The game already looks very close. In the end White was winning by 1.5 pts when Black resigned. No further comments.]
