Yu Bin,9p crushed Lee Sedol!

This game on the preliminary stage of the Tonyang cup was not important, because both opponents had 2-0 score and both 3-0 and 2-1 scores were good enough to go to the next stage.
But it's a bit strange that Yu Bin, 9p (he played in Tonyang under his real name) won the game easily. He is much weaker than Lee Sedol, 9p!
I can imagine how Lee Sedol with his aggressive playing style kills Yu Bin, but it's hard to imagine how Yu Bin with his defensive territorial-oriented style kills Lee Sedol.
Miracle happened!
