In the final fifth game, the fourth vertical debut was played, the newfangled 5th move – diagonally across the cage from the white couple. Many players now consider him to be very strong for Black, calling him fifth in strength (in the 4th debut there are four winning fifth moves). Oosumi was unable to secure the flank with a black stone standing apart, relying on White’s activity, but on the 29th move Black increased the grouping of his stones, further breaking off and extinguishing his opponent’s activity. Nakamura won the last, fifth, game of the major match, the score was 2.5-2.5, and thus Nakamura retained the title of major. Nakamura became a major for the 25th time.
