Positional Judgement Problem 5/Attempts

[Diagram]

Position at move 172

fcarbon: Black + 30?

Herman Hiddema: Agree :-)

Position at move 172

Herman Hiddema: This looks like a reasonable continuation for W173-B182, and after that its about 30 points (white must fill all outside liberties of the center black group at some point, but can count the shared liberties as points).

Position at move 175

fcarbon: Black 176 surprises me: can't white live in the corner?

Herman Hiddema: True. I don't know what the correct way to play would be here. After W77, there must be some way for black to damage white's left side. Though perhaps B76 should simply be at W77
