It's between Lee Sedol (9p) and Qiu Jun (9p).Lee Sedol is ranked number 1 in Korea and Qiu Jun is number 13 in China.This is their second game together. In 2011, Qiu defeated Lee in the quarter finals of the Fujitsu Cup. Qiu took the second place in that tournament.]RE[黑胜白];B[pd];W[dd];B[qp](;W[dq]C[If you don't want your opponent to play the Mini Chinese opening, this 3-4 point is a good idea. ];B[do];W[co];B[cn];W[cp];B[dm];W[fq];B[cf]C[This move is becoming popular these days. ](;W[cl]C[I've never seen this move before in this opening, but it seems as if Qiu had already researched it. ](;B[fc]C[This double approach is reasonable, because white didn't answer black in the top left.];W[fd];B[gd];W[fe];B[ec];W[dc](;B[ge]LB[cl:A]C[Usually you don't want to let your opponent play a double approach like this, but in this game white already occupied A, so white isn't bad either.];W[ce];B[df];W[ed];B[ff]C[This is another possible variation from the double approach. ];W[gf];B[fg];W[gc];B[hc];W[gb];B[hb];W[eb];B[ga];W[fb];B[ie]LB[ge:A]C[Up to here, the variation's done. It's white's turn to play somewhere else. ];W[dl]TR[cf][df][ff][fg]C[Very good place. The game's still even with this move. Black's wall (marked stones) is limited by white's two stones on the left.];B[gp]TR[dm][cn][do]C[Proper move. Black should try to utilize black's marked stones. ];W[fl]C[Nice jump. Qiu thought the center was more important than the bottom. ];B[fp];W[gq];B[dp]LB[hp:B][cq:A]C[Probing move.

White's plan is to play B if black plays at A. White would be happy with that.];B[dj]LB[ei:A][cn:B]C[This is Lee's style. A instead would be common, but Lee wants to take B in sente to help with the fight in the center.];W[cj];B[ci];W[hk];B[gl];W[fm]C[Good sequence. It looks as if black can't save all of his stones. Qiu Jun is very good at this sort of untidy fighting. ];B[hl];W[fn];B[cn];W[di]C[White has ko threats here...];B[ei];W[dn]C[...but black doesn't have any.];B[ik]C[There are no other options for black.];W[eo]C[White took black's stones, but black takes sente. ];B[nc]C[Big move. Black's framework from the center to the top is fabulous. White took some points from the first battle on the left side, but if you look around the whole board, you can see the game's still well balanced between territory and influence. ];W[qi]LB[qh:B][qj:A]C[Right place.

I can't say whether it's good or bad, but it looks nice. ];B[mi]C[Lee can't be calm anymore. Attack! ];W[md]C[Vital point.
