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~~~

The reasons why it is advisable to read

Today, I played a professional. Yongshin Lee 8p who is currently a teacher of New KBC in Hungary. We played a 4 stone handicap game in which reading with foresight should always be the key!

It seems common strategy in handicap for pros to make safe living groups on the sides or corners and once the handicap receiving player builds considerable influence they turn to invade the center moyo and make it a reading contest. Whoever wins the fight will win the game then. The game displayed below shows the game I played and lost. We see all is quite peaceful until in the middle game white becomes split and a fight starts with a black group in between.

What do I learn? More reading training neccesary...

Below we see nice little problem to which I have no solution yet. It is black to play so if you want give it a try.
