Director Jeong vs Haoda4. Black missed the atari, but still won the game!

You may already know the players.
Haoda4 is Kim Taedong, 6-dan. We described him here: GoSensations

Of course, Kim is stronger. His position in Korean amateur ranking must be
somewhere near Lee Kibong, 6-dan. But director Jeong plays another game!
It's not Go. It's a big battle from the early start!

Can we say that Black missed the atari at 112? Or was it the special trick
for getting sente? What do you think?
Please replay the game till the end. The final was very impressive!
