In this game I played massively for influence after my opponent did not care for it some time. Yet I had to give him some 5th line territory for sealing him in at the end. I was wondering, if this play was sound in general. The game turned into a great fight for life in the center. Was there a real hope to win it? For me, it seemed so, until I realized how fast the white group could move toward the upper edge and I could not catch up while keeping my surrounding groups strong enough. Did I make mistakes on the way? Should I try more cuts? Was my play sound at all? Any help would be greatly appreciated.
