It's between Baek Hongseok (9p) and Dang Yifei (4p).Dang won the first game, but Baek won the second and the third games. At this point, Baek is leading the series 2-1.Dang was upset after finishing game three. He was in a good mood in the middle game, but he made some simple mistakes in the endgame, and lost the game. He seemed to be having trouble controlling his emotions, so he might need to learn to be more patient and calm to win important games like these.Baek is in very good form at the moment, especially after winning the second game.You can find more news about the 4th BC Card Cup final here: http://gogameguru.com/baek-hongseok-wins-4th-bc-card-cup/];W[dd];B[qp];W[dp];B[oq];W[qf];B[nc];W[rd];B[fc];W[df]C[The opening so far is identical to game 2, which I reviewed here earlier: http://gogameguru.com/go-commentary-dang-yifei-baek-hongseok-4th-bc-card-cup-final-game-2/];B[jd]LB[jd:B][qh:A]C[In that game, Dang pincered at A instead of B, but he changed his mind in this game.];W[qc]LB[qh:B][cj:A]C[This is a big move, but A is also a possible option for white.

There were few more endgame mistakes from both sides, but in the end, Baek was lucky enough to win. It was Baek's first major title in his entire life. Congratulations Baek!Unfortunately, Baek still has to join the army next year. So we won't see him for two years. That's a critical problem for top Korean players like him, but it doesn't seem easy to solve this situation at present. I'm going to talk briefly about this military service problem for Korean players when I interview Baek in the near future. On the other hand, Dang Yifei missed a really good opportunity to win an international title. However, we should remember that Dang is still only a 17 year old boy, who made it all the way to the finals! We will see his face more often in future international tournaments. I hope you can get a better feeling for this game and enjoy it more with this commentary.Thanks,An Younggil 8phttp://gogameguru.com/])(;B[sq];W[so];B[rs]LB[ps:A]C[Black should have played like this.
