And in this situation the black moyo on the right side has much potential that white must invade.]

White played six moves and black played five moves. Who got more? Clearly black got more. So what happened? See move variation under move L16.

We learned in this game:
1, No need always to follow our opponent, but take initiative to play elsewhere. Thus look at the whole board more often.
2, Build territory in the corner and side is mostly more efficient than build territory in the center.
