On May 17 & 18, the forth game of 65th Meijin-sen between Meijin Moriuchi and challenger Goda 9 dan was held in Hokkaido, Japan. Moriuchi was Sente(Black, or lower side of the diagram) player and he won it in 103 moves. The score is tied by 2-2. You may replay the game here.
The diagram above is the resignation diagram when Moriuchi dropped his Bishop on 4c as the 103 moves. They say Goda resigned too early. After the diagram, there might be lots of variations. I don't know how Sente could clealy win the game if Gote dropped his Rook on 5b after the diagram. Here is my analysis of the variations after it except for R*5b. What difficult variations there are!
