I haven’t play Go in a very long time but I came across this short video of a Master making a major blunder. I don’t understand Japanese but you can hear the gasps and comments about it.
What happened was the Master placed a black stone and created a cross shape. This effectively gave him 1 liberty (you always want two liberties) for survival. This is called ‘atari.’
