White 22 may not be bad, but 24 shows that white is a peace-lover. Until 30, black takes a lot of area with the moving advance (先手). It may be better to put white 24 to 29, then black to 24, a battle may start soon. Undoubtedly, the group of white seeds on the upper-right corner are very strong.
At black 45, black wishes that white can compromise and click at 47, then black can jump away from the white wall. White can’t stand any more, and it tries to control the exit to the center, so 46 comes.
With no option, black determined to destroy all the white area here. Black 47 is a brave move since it can take the advantage of S8 and R12.
White 50 is a calm move, which shows that white may not want to kill black. While it strengthens 38,44 and 46, it also creates chances to harry the lower-right corner of black. White 52 and the following moves give the attempt.
Black is too greedy in this region. White 62 tries to hunt the black dragon. But black has already had a plan for the dragon. Until 81, black is quite safe but leaves 51 and 77 in the center.
However, white 84 and 86 are anxious about its own safety.
White 88 is too risky. It is much better to click at E7. It would be compress the black on the left and enhance the white territory at the bottom.
Black 89 takes the important point immediately. White 90 is a bit greedy. 91 and 93 are quite terrible killers for 88.
Black 97 is too fierce. It should be put at 98.
Black realizes that the attack fails and it becomes senseless as103, 111,115 and 119 show.
White120 and 122 cut off black’s retreat route and the group of black is in great danger.
Black 139 wants to make the last effort. Fortunately, white retreats, and black comes back from the hell after 141.
In fact, it’s quite obvious that black does not have enough “qi”. White 140 is definitely wrong!!!
White 144 attacks the other five black seeds. But H13 may be better. Until 151, black ensures the safety of the group.
Now, we may say that black is leading!
Do note that, black 215 is rather bad, which almost kill the whole group on the right. If white click at S10, then black dies.
Luckily again, white may not notice the chance here. After 227, black saves the right group, white has no chance any more.
