Go (Wikipedia ) is an abstract strategy board game for two players, in which the aim is to surround more territory than the opponent. The game was invented in ancient China more than 2,500 years ago, and is thus the oldest board game continuously played today. Despite its relatively simple rules, Go is very complex, even more than chess.
To find this cache you first have to solve six simple go life and death problems (A to F): in each black play first and have to find unique first move to unconditionaly kill white stones. For each problem you have to write a right move in a form: letter and number (for example intersection O is R12). Then you have to convert letter to number like A=1, B=2, C=3,... (R=18) and multply these two numbers ( 18 * 12 = 216 ). Now add all digits of this result ( 2 + 1 + 6 = 9 ). If this result is not one digit, add all new digit again, until you got only one digit. This way you will get 6 numbers, A to F.
Final coordinates are: N 44.49.D(A-1)B E 020.24.(C+2)F(E+3)
