Next 9 dan best move
Hello, today I had my last statistics lesson. Well I hope it was the last one (if I dont pass my statistics exams I will have to do the course again). It was about indexes, there were two types of them and by mutliplying you can get some third one. As usual I was bored and was thinking about some go and goproblems and suddenly found this position. Finding the solution took me about one hour so I think this problem is quite comlicated - there are several tesujis available and it is hard to pick the one which will serve you best (at least if you want to be really precise). The comments with score I wrote for some moves are without komi, just points on the board plus prisoners. After I came to my room and run MutliGo to check my solutions, I found that if you play optimally, you will win by 0,5 points if white had 6,5 komi and if there were no prisoners at the beginning. So.. 6,5 KOMI, 0 PRISONERS EACH, BLACK TO PLAY AND WIN !!
