Lee Changho (9 dan)
The oogeima shimari is quite unusual, since black will need to play one more move to secure the whole corner.
Black 7 is correct I think. Pincer and extend at the same time.
Up to moe 20, both are doing ok.
Move 33 was vital! White should took that place first, instead of closing the corner
White 36 is too deep perhaps, especially considering black's thickness in the upper. Will K4 be enough for white here?
Black 45 was very good. Attacking the white's lonely stone
Black 53 black has lot of threats by attacking white's group in the upper. The ko was favorable for black.
Move 80 up to here, white is still in great danger.
White 90 I wonder if it's better if white play K2 instead to save the group. I don't think white can live inside
Ryu Dongwan (2 dan)
White resigned at move 104.
Lee Changho played a very strong game. Lee's style recently change a lot. He doesn't try to play peaceful anymore. He tried to play a strong middle game and try to finish it in middlegame, instead of try to win in yose.
