Commentary by Yamashiro Hiroshi 9p, transcribed by Richard Dolen.

Both players played very well so Yamashiro 9 dan did not have many opportunities to comment. In the late middle game, black played very flexibly, while white became focused on tactics and became over concentrated. After a big exchange put black clearly in the lead, he played very solidly and left white no chance to win.
