In this game Shusaku playing against a peer, Black had a rather fast-paced opening, placed group over top edge, right edge and quite a moyo down left bottom corner. But thing start fall in Shusaku's favor when B's invasion and attack on Shusaku's left top group failed, the invasion/attack failure came side effects:
- Shusaku's left top group escaped untouched
- Black's left top group became very weak, as it later played out-only two eyes
- Shusaku's left center group got one sente eye-this change the thickness of that group a LOT
- Black also lost eye shape over the top, that group basically will have to live in gote if Black choose to
- What is worst side effect? one weak group in the center right beside the two weak stones over the right edge-if White(Shusaku) lean against(threaten to attack) one of these groups, he could probably swallow the other group in a big way!
Black choosed to give up the group over the top and strengten the center and right side groups, Shusaku played a very clean yose(end game)-reduced the left bottom white moyo, while Black took his right bottom corner, he broke into the bottom edge and created some territory in the center...while the game record saying Shusaku won by 2 pts, but I think that is 2 pts without komi for White(7-8 pts with komi).
