He's only 12 years old, but the second half of his game was excellent.His reading was quick and accurate, and he wasn't afraid of Lee Changho's severe attack.On the other hand, Lee Changho's opening was elegant and smooth. Up until when he played at A, white was ahead, and after that the game was still good for white because he could attack black's groups.White's cut at B was incomprehensible and, all of a sudden, the game was reversed. White 124 (B) should be the losing move.Lee tried his best to kill black's left side group after that, but Shin showed us his accurate reading, and won the game.This game was an exhibition match but, as you can see, the game was still interesting an exciting.I'm happy to see a very young and talented player's game against Lee Changho, and I hope to see Shin Jinseo reach the top class level in the near future.Feel free to leave a comment if you have any questions.Thanks, Commented by An Younggil 8p http://gogameguru.com/])(;W[go]C[If white connects here,];B[hl]C[This is sente. ])(;W[hl]C[If white tries to kill black by playing here,];B[go]C[Black can cut first, then](;W[ej]C[If white connects here,];B[gm];W[gl]TR[km][lm][in][jn][mo]C[White's marked stones become weak, so black can live fairly easily.];B[nl]C[For example...];W[lo];B[pl];W[ql];B[pk];W[qk];B[nn];W[no];B[on];W[om];B[pm];W[oo];B[kl]C[Black's alive.])(;W[gm]C[If white connects here,](;B[ip]C[Black can play here and,];W[ej]C[If white plays to kill black's center group,];B[nl];W[mn];B[pl];W[jl];B[rl]LB[rj:A][rn:B]C[Now black can connect at A or B.];W[jk]C[And if white cuts off the tail,];B[ir];W[gs];B[es]TR[fo][fp][fq][gq][fr][hr][gs]C[Black can sacrifice some stones in the center and he's still ahead.
