Shusaku Game #14

The turning point of this game is when w tried to attack Black's left center group, instead of running, Black attacked the top center group of White. This is truely 3 birds with one stone: it indirectly help out the left center group; it strengthen the top center black group; and sure it also attacks the top center white group. During the fight around left bottom corner, black gave up 3 stones but took over the whole lower left corner. White put forward its last effort in attacking Black's top center group but because White's own center top group is weak, White didn't get much while Black not only escaped but also expanded the top right corner territory.
