PGB171

Moves 172-181  

White 1 cuts off a group of black stones in the center and now secures a life for a big dragon. But the price is too high. White had to keep calm. First of all there is always a ko at the top. Second the most important issue was to keep the groups connected.

Black 2 is a natural reply and White connects at 3 threatening to cut at two points.

Black cleverly defends one of the cutting points with 4 and White 5 takes another. Now several black stones in the center are doomed. But Black gets 6, separating White's group at the bottom. White brought the trouble home.

White 7 is an attempt to survive by threatening Black's corner. Black replies with 8 naturally and White tries to create an eye shape with 9. Black 10 naturally destroys an eye.
