The 53rd Kuksu Cup preliminary
2009. 6. 4
W: Lee Yong-su 5P B: Lee Hajin 3P
White won by resignation
Usual opening up to W14.
W16 is avoiding complicated variations which may start if white plays at below w16.
Though B25 seems weaker than one space jump it's better in this situation as W's left corner is strong.
If black connects by b33 white would hane at w42 instead of w34.
Black should have played at w40 before playing at b37.
B45 was a probing move, but w46, 48 were severe.
From w46 to w62 is inevitable sequence.
Black 67 is thin but I wanted to play more dynamic moves since I was behind.
W70 is so unbearable for black.
Black 85~89 were probably overplay, but had no choice.
This variation looks very difficult and complicated, but it's natural sequence.
There was no other way for either side.
Up to w134, it's playable for both.
W142~146 are good moves. White made some points here in sente.
Black has tried to find some clue to a reversal with b173, but it didn't work by w184.
When white captures black's two stones by w226, white is leading by about 3.5 points.
