The difference between 7d and 8p

Yesterday I played a game against another current teacher of new KBC, Go Yuyeon 8p. We played at 4 stones and a few mistakes on my side gave here the opportunity in fighting to end the game quickly.

Today I played with a former KBC teacher, Hong Seul-ki 7d Amateur. We played at three stones and due to a mistake in judging the aji of my moyo I lost by 14 points in the end.

So what is the difference between those two games except the obvious one stone handicap difference? Similar at first sight is the definite style of making the game unusual and complicated as fast as possible. We weaker players tend then to make mistakes that will be exploited to maximum profit. See the first game as example.
Another distinct fact is that in handicap games I play and see the course of the game usually goes for a moyo-style or influence based game, as if guided by invisible hand. And then when the time is right a deadly invasion or complicated reduction come.
The 8p resolutely struck down the first mistakes to full intent while against the 7d one could hold on and suffer some damage first before sinking completely. The ko in the second game was a tremedous step forward for white but only the mistake by black in the end allowing the reduction sealed the fate of the game.

Hope vs despair in a reading battle. I need to study to read more and read more quickly. Time to prepare for the next battles against pros~~~
