W finally found good time to resign. The corner'd become ko or seki. You can try to figure it out. :) The variation in the bottom right corner was totally new for me, and the result seemed a bit favourable for W. B's attachment at A was wrong, and the game became good for W. B's 97 at B was keen, but 107 at C was mistake, and W's counter attack at D was really a good timing. W's tesuji at E was good, and W kept reading the game. W's attachment at F was a bit too aggressive, and the game became chaos. B's choice from G was correct, and there was no chance for W after that.A fight began at move 20, and the fighting never stopped until almost the end of the game. Both players are infighters, and games between them are always interesting and full of excitement and tension. As Gu Li won this game, the score is tied at 2:2, with one game left. That game is a real final, and it will be very thrilling to watch the game. (update: Lee Sedol won game 5 and won the BC Card Cup)This game was also very complicated, but not as much as the game between Gu Li and Kim Jisuk which I commented a month ago. :D There must be some mistakes in my commentary, but you'll still enjoy watching the game I'm sure.
