Knotwilg: while I assume joseki would fall under public domain (if even problems do), I'm not sure about all the specific diagrams explaining refutations of improper moves. Perhaps quote those as being the work of 廖渝生 (Liao Yu Sheng), the author of 围棋定式大全 (WeiQi DingShi DaQuan) (ISBN-9787536458857).
While there were almost no kids at School Stairs, School Pink Stones seems to be doing well for itself during summer. The 2-week recess was used to paint the walls, both inside and outside, and it has been cleaned quite thoroughly. Since a new semester just started at the school, there are a lot of new kids in our class. Many of these appear to be first-time students of Yan Laoshi. They've been assigned the same tesuji and joseki book as us. I played two of the new kids yesterday and today, and found - perhaps unsurprisingly - they are not yet at the same level of the kids that were here before them. I won all four games, but played really poorly.
In yesterday's first game my opponent made a pretty big mistake in the opening, and then lost all sense of direction for a couple of moves. I took advantage and had a lead which should have been comfortable. I should learn to play solid and thick moves if this happens again. I didn't, making the game closer than it should have been.

The second game of the day was played with a 9-year old girl who's new to the school. When I noticed a mistake in joseki, I quickly went from trying to punish the mistake to overplaying. I was not punished, but should have been. When I realized I was being a bully on the board, I let a second white group make easy life, and guided my opponent towards the big points in the endgame.

In the second game, I played almost at the kid's speed (no thinking), and the result on the board was clear about who was having the better end of that deal. When I noticed I wasn't doing so well against the little girl I beat by over 40 points yesterday, I overplayed big-time. In the end the game became really close, and I managed to sneak my way towards a close win.

After the review, I went over the game once more with Liu Jia Yi, and highlighted why her moves were good and mine bad. Also, she has gained the rights to all snacks I receive from Yan Laoshi.
Except for the losses against the three 5-dan opponents, all of my games this week have left a bit of a foul aftertaste. It doesn't feel good to win when you know you played a poor game. Playing stronger opponents forces me to look for better moves. But why does playing weaker opponents lure me into playing worse? I should work on playing a more consistent game.
Because we still study go most of the day on our free days, I feared that the problem with this week's games may be non-go related: I need some time off. I ditched my problems today, played some browser games, went out for basketball and did absolutely nothing productive. Right now me and my room mate are both lying in opposite corners of the room, and the AC remote is right in the middle of said room. Neither of us can reach it from our beds, and it doesn't look like either one is getting up soon. Forsti: if you're reading this: I can do this all day, man. I'm not getting that remote.
