Warm up game on Fox

 Playing a warm-up game on the Fox Go Server!

I was playing black and the opening went well. We got some very simple corner positions and the game was close but I felt good. White was left with a weak group in the bottom left corner and some potential weaknesses in their top group. Black's groups were all stable and strong.

However the game took a rough turn. I made a reading error on the right side of the board and lost four stones. I have to immediately go back and protect my weakness at Q4, giving white the initiative to start playing somewhere else on the board.

I was trailing the game by a lot. White was winning by about 20 points. I was just hanging in there waiting for a chance to reverse the game. And oh, did a chance come!

 

 Here is the picture of the score estimator after the game. You can see my first mistake around move 70 swinging the game in white's favor and something dramatic happening at move 167!

White was working hard to surround and kill the black stones in the top left (marked with triangle) but overlooked black's sneaky counter squeeze building up in the center. At this point if black finds the right move they can completely reverse the game! (hint: count liberties!)

 This throw in at K13 works so well! Now the white A group will die, saving black's B group and subsequently killing white's C group. In the game white managed to kill off the D stones in exchange but black got a much better end of the deal. From here there is no significant fighting available and the game just coasts easily to the end with nothing exciting.

 The final position of the game, black winning by 41. I was lucky to find a chance to reverse the game. Gotta be more careful reading in the early game!
