He prefers to play a long territorial game. On the other hand, Iyama prefers a fighting game, as he's confident at fighting and still quite young. In general, younger players tend to be keener on fighting.Iyama won the Honinbo title, defeating Yamashita Keigo, just four days before this game.];W[dc];B[dq]C[Iyama chooses this cross opening.];W[pp];B[ce]C[It's quite rare to see a cross opening like this in professional play these days.];W[dh];B[cj]LB[fc:C][gc:D][ed:B][gd:E][fe:A][df:F]C[There are so many options for black in this position, and this is one of them.

Attaching at B was an interesting tesuji as well.However, white played some questionable moves afterwards and wasn't able to reverse the game.On the other hand, Iyama showed his confidence at fighting, and he managed the game very well. He made a mistake at D, but he still kept his calm, and didn't allow white to catch up.Iyama Yuta became the new Gosei, defeating Hane Naoki 3-0 in the final.It's a short game, but I hope you to learn some nice tesuji and tactics by watching their play and reading the commentary.
