It is afraid that aggressive players normally don't allow White connect at 'a'.];W[kq];B[mo];W[lp]LB[lq:a]C[W28 is necessary order, to guard against Black's tactic at 'a'.];B[lo];W[no];B[ip];W[iq]LB[hp:a]C[W32: Park Junghwan decides to defend and perhaps he is happy with the result, otherwise for White to make diagonal at 'a' is more positive.];B[hp];W[hq];B[hm]C[B35: Black fixes shape, White's efficiency at bottom is not high, Black appears more vivid and interesting.];W[nc];B[ob];W[kd];B[eb];W[fm];B[ch];W[bg];B[dh];W[dg]C[W44: After W36 and W38, White attacks with W40, White's playing sequence is questionable, since the clamp of B41 is a good move. With W42 White is reluctant to tolerate at 44. However as for the counterattacking result, White plays near Black's iron head of B39, White is very painful and starts to sink into passivity.With W36 White can directly attack with W40, or with W38 White can first play hane at 39, White would be much better off.];B[eh];W[ge];B[ck];W[gk];B[gh];W[hd];B[ek]C[B51: Black easily achieves safety.];W[ik];B[hj]C[B53 is good sequence.];W[hl];B[gm];W[fl];B[fn]C[B57: White counterattacks with W54, however this helps Black fix shape with B55 and B57, the counterattack of W54 is ineffective.];W[dl];B[dk];W[en];B[fo];W[im];B[in];W[jn];B[jm];W[il];B[jo]C[B67: Black handles the bottom well, White clearly fails and gains nothing by attacking from W40. Black establishes superiority.];W[pf];B[qf]LB[qe:a]C[B69 is strong. For Black to make diagonal at 'a' is also interesting move, since if White blocks at 69 next, there will be no difference if White makes high or low corner approach. If White doesn't block down at 69, Black can crawl at 69 and it is also very big.];W[pc]LB[qg:a]C[W70 is the only counterattack.
