Hi! As my last problem still has many problems in it, I decided to make a new problem hopefully without mistakes this time (so I can say this is my first problem =). The problem occured in a game between a 6k and a 18k during a handicapped go tournament at a camp. As I found it interesting, decided to create it on goproblems.
