Midnight Madness

Everyone sane had long gone off to bed, but two of us decided to stay up and play a game. My big regret in this game was not invading his left side moyo when I could have. It was so obvious and easy when she reviewed it later. Still kicking myself over it.

This was the position.



As you see, W is quite open on the left and the correct way to play would be this.



Instead, I decided to make the invasion much harder on myself, and I played Black 1.



Now W has some ideal moves to convert the left from moyo into territory. Bad idea for Black. It is pretty easy to see that now it is way harder to invade the left.

Friday night lesson. "Do not help your opponent."
