Here is the Crane's Nest:
This capture was satisfying, but didn't give me nearly enough of an advatage to win the game. It happened fairly early in the game, and my opponent clearly outplayed me throughout the opening. and was leading by about nine points when I made a fatal cut that resulted in the capture of nine stones. My opponent went on to atari the cutting stone so as to make life along the bottom. The 18 point swing was enough for me to win the game with a final score of +12.5 for white.
Earlier in the game I had attempted a throw in at t7 which made the cut of r4 a failure because the black stones along the right still had two liberties and black could atari from s4 since there was no shortage of liberties for black on the left. Naturally I tenukied at that time. It was only after the final liberty of the black stones along the bottom was taken that the cut worked since either atari would result in a loss for black, albeit the atari from r3 made the most sense.
