A-C are possible. If black pushes at A, there'd be many  complicated variaions. ];B[dr];W[cq];B[kq]C[This is most common today. ];W[np]LB[op:B][gq:A]C[This is one of Iyama's favourite moves. A or B is more common instead. ](;B[fp]C[Normal move. ](;W[pn]LB[np:A]C[This might look very strange for kyu players, but this is also possible.

Top is more important than right side for W. ];B[qf];W[gc]C[Iyama's style of play. It looks like Japanese style. Take it easy and peaceful. ];B[ko]C[Looks slow, but very good. W could have played here instead of W20. ];W[em]C[Necessary for W. If W doesn't play here, B'd directly play here.];B[oo];W[no](;B[on]C[This could be a mistake. ](;W[nm]C[Proper response. ];B[om];W[nl];B[ol];W[nk];B[pj]C[Up to here, it looks successful for B, but it isn't indeed. It doesn't look that natural making territory on the right. ];W[hp]LB[nk:A]C[Good invasion. W can come here without any trouble because W'sA group is not weak any more. ];B[km]C[Good jump. There's no good answer to W's invasion, so B just jumped out.  ];W[hn];B[io];W[gp]LB[ho:A]C[Good answer.

Playing at A is also very good, but Iyama might have thought the game was playable for W. Up to here, the opening is successful for W, and it was a very good news for Iyama because Gu Li's opening is extreamely strong. ](;B[ch]C[Good split. When you split, you'd better play on the third line as this, and you should consider of the surroundings. ](;W[cf]C[This is right direction.

B missed a very good chance at 65, and the game is still favourable for W. In addition, there're bad aji from A. ];B[eh]C[Good jump. Apparently B has more territory, but W is really thick, and has more potential over the centre. ];W[di]C[Very sharp. ](;B[dh];W[bj]C[Good follow up. W is trying to get rid of B's base. Iyama's play in this game is amazing. Iyama defeated Lee Sedol 9p just before this game, and he is playing more confidently than before. ];B[ce]C[Nice tesuji. You can see such a creative move in Gu Li's game quite often, ];W[de];B[bf]C[Good follow up. ];W[be];B[bg]LB[cg:A]C[This extension is right.

As you can see, Iyama is also very good at local fighting. His play isn't typical Japanese style.
