With this win, Kim Jiseok won the 18th GS Caltex Cup, defeating Lee Sedol 3-0. It's was a highly unexpected result, but Kim demonstrated his reading ability against Lee Sedol.Kim was promoted to 9p after winning this title.It was a very exciting and thrilling game. After white went into black's area at A, neither player stopped fighting until the very end of the game.White missed a very good chance to finish the game at B, and the C was the losing move.Kim Jiseok was behind for most of the game, but he never gave up. He kept tring to make the game complicated, and eventually reversed the game.On the other hand, Lee managed the whole game wonderfully, but he missed several good chances.
