A different approach altogether is exemplified by the game below between Chang Hao (White) and Yi Se-tol last December. This was part of Yi's 19-game winning streak in the China Weiqi League. His participation in this event (or more precisely his refusal to hand over 5% of his winnings to the Hanguk Giwon) is part of the charade that led to him taking 18 months leave of absence from pro go, supposedly because he was exhausted. Between yawns, he kept up his streak until July 2009.
His choice of response was Black 9.
The corner sequence then looks straighforward enough, but the game commentary focuses on whether Black 13 was severe enough. A move at 19 instead might be better. The next diagram shows that White now cannot live in the same way as the game.
White has to replace 6 with 7, strengthening Black with A, or live in some other way, e.g. with White 2 at 11 or 12. In that case he has a choice between leaving bad aji in the corner if he takes sente to play on the upper side, or living securely but in gote.
