Thick and solid, very good at counting and endgame. However, he sometimes makes mistakes when he's in time trouble.];B[qk]C[Na Hyun became a pro last year, but he already beat Sakai Hideyuki 8p and Peng Liyao 5p before this game.];W[nc];B[pf];W[pb];B[fq];W[cn];B[qc];W[kc];B[dr];W[cq];B[iq]C[Nothing special so far in this opening.](;W[jp]C[This shoulder hit is pretty common today. ];B[jq];W[kp];B[ho];W[jn]LB[gp:A]C[W aims at A later. ];B[cf];W[fc]LB[fd:A]C[W normally answers at A in this situation, but Na prefers to play more safely as Kong Jie prefers to play solid moves. ](;B[dj]C[Make it simple. ];W[po]C[Last big move. ];B[oo]C[This attachment is rare to see, but it looks good in this situation. ];W[on];B[op](;W[pm];B[nn]C[The game is still even as there were no questionable moves so far.];W[nm];B[mn];W[mm];B[ln];W[kl]C[Kong is very good at this sort of 'normal' game, so most Go fans would have expected Kong to win. ];B[jm]C[The first fight has just begun. ];W[km];B[kn];W[in];B[jl];W[jk];B[il]C[Right move, though it doesn't look pretty. ];W[hn];B[lm]C[W appears to be in trouble. ](;W[kk]C[This connection is hard to think of. ];B[ol];W[om];B[ll]C[W's groups are all split, and B takes the initiative in the game. I couldn't find W's mistake, but you know that Na Hyun is not very good at the opening. ];W[nk];B[lk];W[ji]C[W keeps his cool with this jump. ];B[hk];W[fn];B[hi]C[The flow of the game is favorable for B, but actually the game is still close. ];W[pk];B[ql];W[pl];B[qi];W[li]C[Nice jump. W is not in a hurry. ];B[lj];W[ki];B[ld];W[lc];B[mi]C[B doesn't lead the game on territory, so he tries to separate W's groups and attack. ];W[pi](;B[mh]C[Good move. B is in good mood. ];W[qh];B[qj];W[oh];B[qn];W[ng];B[nj];W[ne]C[The game is still playable for both. ];B[qm]C[Big move. It looks as if B takes the lead of the game, but it's close because W is thicker and has more potential in the center. ];W[rf]C[W starts to attack.];B[qb];W[pc];B[re]C[Good tesuji. ];W[qe];B[qd];W[rd]C[B can't live inside, so B has to go out. ];B[od]C[This is a good way to move out.](;W[rh]C[Right answer.];B[nd];W[mc];B[md];W[lf];B[ke]C[After B comes out here, the game becomes more complicated. ];W[kf];B[je];W[gj];B[hj];W[ig]C[W plays carefully because this W group is not yet strong enough to attack B's top right severely. ];B[ic];W[jb];B[nf]C[Good tesuji. ];W[mg];B[gg]C[W is short of territory, but thick. The game is still even. ];W[gh]C[Good counter attack! W can fight rather freely as W's stones around here are stronger than B's. ];B[hh];W[hg];B[gf];W[fh];B[fj]C[Good move. ];W[he];B[rc];W[se];B[me]C[This group is alive. ];W[eg];B[dh];W[pn];B[qo];W[mp];B[np];W[df]TR[gf][gg]C[The game is still close, but it seems to be favorable for W, as W captures B's two marked stones. ];B[ce];W[cd];B[dg];W[ef];B[cm]C[Good move. ];W[dm];B[cl];W[cr];B[lr]LB[cr:22]C[It's miai with W 122. ];W[bn]C[Right answer. ];B[ie]TR[ic]C[To save B's stone on the top. ];W[hd];B[jc];W[mq];B[ip];W[io](;B[go]C[Mistake. ];W[gn];B[gi]LB[gn:32][go:31]C[This move becomes necessary after B exchanges 131 for 132. ];W[or]C[Big move. ](;B[mr]C[Proper move, but B loses some points in this area. ](;W[nq];B[oq];W[pr];B[qr]LB[qq:B][nr:A]C[Right answer.

W was worrying about some aji in the center, but there wasn't any serious problem. ];B[la]C[Good endgame move. ];W[ma];B[mb];W[lb];B[na];W[nb];B[bm]C[Very big.

It was an amazing game for Na Hyun. He even reversed the game in the endgame against Kong Jie, whose endgame and counting are regarded as the best in the world. There wasn't any big fight, but there were small local fights, and the game stayed even for a long time. W made a crucial mistake at 150 (A), and the game was reversed, but B just missed an exchange at A, and W didn't miss his second chance.Na Hyun is only 16 years old and became a pro last year, but as you can see, he managed the whole game very well.On the other hand, it's a pity for Kong Jie. He seemed to be nervous as he faced a young unknown player. His play was normal, but unusually, it's hard to find his brilliant moves in this game.You might be able to feel the tension between B and W from their endgame moves, and I hope you enjoyed watching them.
